Safety
Training
1. Carefully read this Owner’s Manual, the
separate Engine Owner’s Manual, and any
other literature you may receive. Be thor-
oughly familiar with the controls and the
proper use of the tiller and its engine.
Know how to stop the unit and disengage
the controls quickly.
2. Never allow children to operate the
tiller. Never allow adults to operate the
tiller without proper instruction.
3. Keep the area of operation clear of all
persons, particularly children and pets.
4. Keep in mind that the operator or user
is responsible for accidents or hazards
occurring to other people, their property,
and themselves.
Preparation
1. Thoroughly inspect the area where the
tiller is to be used and remove all foreign
objects.
2. Put the Wheels/Tines/PTO Drive Lever
into NEUTRAL before starting the engine.
3. Do not operate the tiller without
wearing adequate outer garments. Avoid
loose garments or jewelry that could get
caught in moving parts.
4. Do not operate the tiller when barefoot
or wearing sandals, sneakers, or light
footwear. Wear protective footwear that
will improve footing on slippery surfaces.
5. Do not till near underground electric
cables, telephone lines, pipes or hoses. If
in doubt, contact your telephone or utility
company.
6. Warning: Handle fuel with care; it is
highly flammable and its vapors are
explosive. Be sure to take the following
precautions:
a. Store fuel in containers specifically
designed for this purpose.
b. The gas cap shall never be removed
or fuel added while the engine is
running. Allow the engine to cool
for several minutes before adding
fuel.
c. Keep matches, cigarettes, cigars,
pipes, open flames, and sparks
away from the fuel tank and fuel
container.
d. Fill fuel tank outdoors with extreme
care. Never fill fuel tank indoors.
Use a funnel or spout to prevent
spillage.
e. Replace all fuel tank and container
caps securely.
f. If fuel is spilled, do not attempt to
start the engine, but move the
machine away from the area of
spillage and avoid creating any
source of ignition until fuel vapors
have dissipated.
7. Never make adjustments when engine
is running (unless recommended by
manufacturer).
Operation
1. Do not put hands or feet near or under
rotating parts. Do not allow hands or any
other part of the body or clothing near the
rotating tines or near any other moving
part. The tines begin to rotate forward
once the engine starts, the Tines/PTO
Clutch Lever is in the ENGAGE position,
the Forward Interlock Levers are squeezed
closed and the Wheels/Tines/PTO Drive
Lever is shifted to FORWARD. The tines
rotate in Reverse whether the Interlock
Levers are closed or open.
2. Exercise extreme caution when on or
crossing gravel drives, walks, or roads.
Stay alert for hidden hazards or traffic. Do
not carry passengers.
3. After striking a foreign object, stop the
engine, remove the wire from the spark
plug wire and prevent it from touching the
spark plug. Thoroughly inspect the
machine for any damage and repair the
damage before restarting and operating
the machine.
4. Exercise caution to avoid slipping or
falling.
5. If the unit should start to vibrate abnor-
mally, stop the engine, disconnect the
spark plug wire and prevent it from
touching the spark plug, and check imme-
diately for the cause. Vibration is
generally a warning of trouble.
6. Stop the engine, disconnect the spark
plug wire and prevent it from touching the
spark plug whenever you leave the
operating position, before unclogging the
tines, or when making any repairs, adjust-
ments or inspections.
7. Take all possible precautions when
leaving machine unattended. Stop engine.
Disconnect spark plug wire and move it
away from spark plug. Remove ignition
key on electric start models

Section 1: Safety
8. Before cleaning, repairing, or inspect-
ing, stop the engine and make certain all
moving parts have stopped. Disconnect
the spark plug wire and prevent it from
touching the spark plug to prevent acci-
dental starting.
9. The flap on the tine hood must be
down when operating the tiller, unless
using the Hiller/Furrower attachment.
10. Never use the tiller unless proper
guards, plates, or other safety protective
devices are in place.
11. Do not run engine in an enclosed
area. Engine exhaust contains carbon
monoxide gas, a deadly poison that is
odorless, colorless, and tasteless.
12. Keep children and pets away.
13. Never operate the tiller under engine
power if the Wheel Speed Lever is in the
FREEWHEEL position. In FREEWHEEL,
the wheels will not hold the tiller back and
the revolving tines could propel the tiller
rapidly, possibly causing loss of control.
Always engage the Wheel Speed Lever in
either FAST or SLOW position before
starting the engine or engaging the tines
with the Wheels/Tines/PTO Drive Lever.
14. Be aware that the tiller may unex-
pectedly bounce upward or jump
forward if the tines should strike
extremely hard packed soil, frozen
ground, or buried obstacles like large
stones, roots, or stumps. If in doubt
about the tilling conditions, always use
the following operating precautions to
assist you in maintaining control of the
tiller:
a. Walk behind and to one side of the
tiller, using one hand on the han-
dlebars. Relax your arm, but use a
secure hand grip.
b. Use shallower depth regulator
settings, working gradually deeper
with each pass.
c. Use slower wheel, tine and engine
speeds.
d. Clear the tilling area of all large
stones, roots and other debris.
e. Avoid using downward pressure on
handlebars. If need be, use slight
upward pressure to keep the tines
from digging too deeply.
f. Before contacting hard packed soil
at the end of a row, reduce engine
speed and lift handlebars to raise
tines out of the soil.
g. In an emergency, stop tines and
wheels by shifting the
Wheels/Tines/PTO Drive Lever
into NEUTRAL. If you can not
reach the lever or have lost control
of the tiller, let go of the handle-
bars and all controls. Do not
attempt to restrain the tiller.
15.
Do not overload the tiller’s capacity by
attempting to till too deeply at too fast a
rate.
16. Never operate the tiller at high
transport speeds on hard or slippery
surfaces. Look behind and use care when
backing up.
17. Do not operate the tiller on a slope
that is too steep for safety. When on
slopes, slow down and make sure you
have good footing. Never permit the tiller
to freewheel down slopes.
18. Never allow bystanders near the unit.
19. Only use attachments and accessories
that are approved by the manufacturer of
the tiller.
20. Use tiller attachments and acces-
sories when recommended.
21. Never operate the tiller without good
visibility or light.
22. Never operate the tiller if you are
tired, or under the influence of alcohol,
drugs or medication.
23. Operators shall not tamper with the
engine-governor settings on the machine;
the governor controls the maximum safe
operating speed to protect the engine and
all moving parts from damage caused by
overspeed. Authorized service shall be
sought if a problem exists.
24. Do not touch engine parts which may
be hot from operation. Let parts cool
down sufficiently.
25. POISON/DANGER—CAUSES
SEVERE BURNS. The battery on electric
start models contains sulfuric acid. Avoid
contact with skin, eyes or clothing. Keep
out of reach of children.
Antidotes:
External– Flush immediately with lots of
water.
Internal– Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten eggs or vegetable oil. Call a
doctor immediately.
Eyes– Flush with water for 15 minutes.
Get prompt medical attention.
26. DANGER– BATTERIES PRODUCE
EXPLOSIVE GASES. Keep sparks, flame
or smoking materials away. Ventilate
when charging battery or using in an
enclosed space. Always wear safety
goggles when working near battery.
27. Please remember: You can always
stop the tines and wheels by releasing all
controls, or by moving the ignition switch
and/or throttle control lever on the engine
to OFF or STOP.
28. To load or unload the tiller, see the
instructions in Section 4 of this Manual.
29. Use extreme caution when backing or
pulling the machine towards you.
30. Start the engine carefully according to
instructions and with feet well away from
the tines.
31. Never pick up or carry a machine
while the engine is running.
32. When loading or unloading the tiller,
always disengage tines and use slower
wheel and engine throttle speeds. Use
sturdy ramps wide and strong enough to
easily support the tiller (280-to-325 lbs.,
depending on model) and operator.
Never go down ramps in FORWARD
drive—the tiller could tip forward,
exposing you to the tines (which should
be disengaged). Always use REVERSE
drive and back down ramps. To go up
ramps, use FORWARD drive and follow
the tiller.
33. The Forward Interlock Safety System
should be tested for correct functioning
every time the tiller or PTO power unit is
used. See Section 4 in this Manual.
34. If using the optional Dozer Blade,
either remove the tine attachment, or
disengage the tines with the Tines/PTO
Clutch Lever. Revolving tines are
dangerous.

STEP 6: Check Gear Oil Levels
Your tiller has two separate transmis-
sions: one for the Power Unit (Figure 2-
12), the other for the Tine Attachment
(Figure 2-13). Both transmissions were
filled at the factory with SAE #85W–140
weight gear oil (with an A.P.I rating of
GL-4). Check level in both transmis-
sions to verify that they are still correct.
See Section 5,
Transmission Gear Oil
Maintenance for complete information
on how to check and fill the transmis-
sions.

Owner’s Manual provided with your tiller
BEFORE pouring the full amount of each
bottle into the engine.
IMPORTANT:
• Change engine oil after first 2 hours of
new operation.
• Check engine oil level every 5 hours of
operation or each use.
STEP 8: Attach Engine Throttle
Lever and Cable
For shipping purposes, the throttle cable,
together with the throttle lever, is wound
around the engine. Carefully unwind the
cable. If the throttle control label is
covered with a clear protective coating,
peel it off.
To attach the throttle lever and cable:
1. Run the throttle cable up the inside
edge of the right handlebar and position
the lever as shown in Figure 2-14.
2. From the outside of the handlebar,
insert the curved head screw (A, Figure 2-
14), through the handlebar and the center
hole in the throttle lever mounting
bracket.
3. Loosely install the flanged lock nut
and move the throttle lever back to the
STOP position.
4. From the lever side of the bracket,
thread a pan head screw (B, Figure 2-14)
through the small hole in the throttle lever
bracket and into the handlebar. Tighten
the screw securely.
5. Securely tighten both the flanged lock
nut and the curved head screw.

Introduction
This section describes the location and
function of the controls and features on
your tiller. Refer to Section 4,
Operation
for detailed operating instructions.
Practice using these controls, with the
engine shut off, until you completely
understand the operation of the controls
and feel confident with each of them.
IMPORTANT: Refer to the separate engine
manufacturer’s Engine Owner’s Manual
for information about the controls on the
engine.
NOTE: All references to left, right, front
and rear of the machine are based on a
position behind the handlebars and facing
forward.
PTO Attachments Feature
In addition to powerful tilling capability,
you can quickly convert your machine
into a PTO (Power Take-Off) Power Unit
that is capable of towing or powering
various TROY-BILT attachments.
You can access this capability by
removing the tines attachment (powered
by the PTO Power Unit). The PTO Power
Unit is then available for engine powered
attachments, or for pulling or towing non-
powered attachments. See Section 4,
PTO Power Unit for detailed information
on installing and operating TROY-BILT
PTO attachments.
Wheels/Tines/PTO Drive Lever
Use the Wheels/Tines/PTO Drive Lever (A,
Figure 3-1) to engage and disengage
power to the transmission.
This lever has three operating positions:
FORWARD, NEUTRAL and REVERSE.
• FORWARD is engaged when the lever is
moved down until the clutch roller (G,
Figure 3-2) engages into the detent
position under the adjustment block (H,
Figure 3-2). You will definitely feel the
lever engage into this position.
Use the FORWARD setting to move the
wheels and tines forward, or to apply
power to an optional PTO (Power Take
Off) attachment. (See also
Forward
Interlock Levers.)
To stop the wheels, tines or any PTO
attachment, move the lever to NEUTRAL
by tapping the lever upwards (Figure
3-3) and releasing.
• REVERSE is engaged when the lever is
pushed (with an open palm) all the way
up and held in that position (Figure 3-4).
Use this setting to move the wheels in
reverse. To stop moving in reverse,
release the lever; it automatically returns
to the NEUTRAL position.
IMPORTANT: Do not operate the tines or
any PTO attachment in REVERSE.
• NEUTRAL is this control’s normal non-
operating position. The lever returns to
NEUTRAL when it is tapped out of the
FORWARD position or released from the
REVERSE position. NEUTRAL position
is between FORWARD and REVERSE
(Figure 3-3). Use this setting to stop
the wheels, tines or any PTO attach-
ment.
IMPORTANT: Always shift to NEUTRAL
before starting the engine or before
engaging the wheels, tines or any PTO
attachment.
Forward Interlock Levers
The Forward Interlock Levers (B,
Figure 3-1) are attached under each
handlebar grip.
You must squeeze at least one of these
interlock levers up against the handlebar
grip whenever the Wheels/Tines/PTO
Drive Lever is engaged in FORWARD
position.

If both Forward Interlock Levers are
released before first returning the
Wheels/Tines/PTO Drive Lever to
NEUTRAL, the engine will stop.
IMPORTANT: The Forward Interlock
Levers are a safety control that stops the
engine should you lose control while
going forward and cannot shift into
NEUTRAL.
Wheel Speed Lever
Use the Wheel Speed Lever (C, Fig. 3-1)
to select one of three operating positions:
SLOW, FAST or FREEWHEEL.
• SLOW – Lever moved all the way down.
Most effective for normal tilling or for
low-speed transport.
• FAST – Lever moved all the way up.
Most effective for cultivating or for fast-
speed transport.
• FREEWHEEL – Lever in between SLOW
and FAST (wheels will roll freely). Used
when transporting the machine on level
ground without engine power, and when
using stationary PTO attachments.
IMPORTANT: To avoid transmission
damage, always move Wheels/Tines/PTO
Drive Lever into NEUTRAL before shifting
the Wheel Speed Lever.
IMPORTANT: When shifting into SLOW
or FAST, gently roll the machine forward
or backward to help fully engage the
wheel gears. When engaged, the wheels
will not turn unless the engine is running
and the Wheels/Tines/PTO Drive Lever is
engaged in FORWARD or REVERSE.
Tines/PTO Clutch Lever
Use this lever (D, Figure 3-1) to engage or
disengage power from the transmission
PTO clutch to the tines or any PTO attach-
ment. This control has two operating
positions: ENGAGE and DISENGAGE.
• ENGAGE – Lever moved into detent slot
farthest from engine. Use this position to
operate tines or other PTO attachments.
After shifting to ENGAGE, briefly operate
machine in FORWARD to help fully
engage the PTO clutch.
• DISENGAGE – Lever moved into detent
slot nearest engine. Use this position to
disengage power to tines or other PTO
attachments before transporting, loading,
turning, or operating in reverse.
IMPORTANT: To avoid transmission
damage, always move the Wheels/Tines/
PTO Drive Lever into NEUTRAL before
shifting the Tines/PTO Clutch Lever.
Depth Regulator Lever
Use this lever (E, Figure 3-1) to regulate
the tilling depth of the tines. This control
also has a TRAVEL position, which
enables transport with the tines off the
ground.
To operate the lever, lift up on the handle-
bars, pull the Depth Regulator Lever
straight back, and then slide it up or down
to one of the eight detent height settings.
The eight detent positions offer a range of
tine height settings. This enables you to
select the height that is most effective for
a particular condition. The top detent
position is the TRAVEL setting. Use the
second or third detent from the top for
shallow tilling and cultivating. Use the
other detents for deeper tilling and for
power composting.
Handlebar Height Adjustment
Lever
Use this lever (F, Figure 3-1) to adjust the
handlebars to one of two height settings.
1. To change the height, hold the handle-
bars with one hand and loosen the lever in
a counterclockwise direction.
2. Move the handlebars to one of the two
preset height settings.
3. Retighten the lever.
NOTE: You can swap the positions of the
inside handlebar ratchets to change the
two preset settings by approximately four
inches higher or lower. See Section 2,
Step 2: Attach Handlebar for detailed
assembly information.
To avoid personal injury,
always place the tines in the TRAVEL
position before starting the engine.
This prevents the tines from touching
the ground until you are ready to begin
tilling.
WARNING
Engine Throttle Lever
Use the throttle lever (G, Figure 3-1) to
adjust engine speed as well as to start
and stop the engine.
Move the lever away from the STOP
position before starting the engine.
Engine speeds are variable and range
between the FAST and SLOW. Use the
STOP position to turn the engine off.
NOTE: A secondary throttle lever is
located on the front of the 8HP and 10HP
engines. A separate On/Off switch may
also be available on the engine. (See
Engine Owner’s Manual for information.)
Engine Controls
Refer to the engine manufacturer’s Engine
Owner’s Manual (included in the tiller lit-
erature package) to identify the controls
on your engine.
IMPORTANT: An engine On/Off switch, a
secondary throttle control, a choke lever
and a fuel line shut-off control may be
located on the engine. Refer to your
Engine Owner’s Manual for detailed
information.

Operating the Tiller
When first practicing, keep the Tines/PTO
Clutch Lever in DISENGAGE position and
the Wheel Speed Lever in SLOW position.
The following pages provide guidelines
for using your tiller effectively and safely
in various gardening applications. Be
sure to read
Tilling Tips & Techniques, in
this Section, before you actually put the
tines into the soil.
This is a traditional standard-rotating-tine
(SRT) tiller with forward rotating tines. It
operates in a completely different manner
than counter-rotating-tine (CRT) tillers, or
from front-tine tillers.
Moving the Tiller Forward and Tilling
1. Start the engine and gradually increase
engine speed to FAST (see
Starting the
Engine, this Section).
2. Test the Forward Interlock Safety
System. See Testing Forward Interlock
System
, this Section.
3. When practicing, set the Depth
Regulator Lever to Travel position.
Otherwise, set the Depth Regulator Lever
to a desired depth.
4. Move Tines/PTO Clutch Lever to
ENGAGE position if you want the tines to
turn. If practicing, leave in DISENGAGE.
IMPORTANT: Do not move Tines/PTO
Clutch Lever to ENGAGE unless
Wheels/Tines/PTO Drive Lever is in
NEUTRAL. Tiller damage may occur!
5. To move the tiller forward and engage
the tines, squeeze and hold either Forward
Interlock Lever (Figure 4-3) against the
handlebar grip, then move the
Wheels/Tines/PTO Drive Lever down to
FORWARD position.
To avoid serious personal injury or
damage to equipment:
• Always place Wheels/Tines/PTO Drive
Lever in NEUTRAL before starting
engine, and before engaging wheels,
tines or other PTO attachments.
• Be sure there are no obstacles behind
you before moving in reverse.
• Wheels/Tines/PTO Drive Lever should
automatically return to NEUTRAL
when released from REVERSE
position. If it does not, move lever to
NEUTRAL manually and discontinue
use until you adjust the lever. See
Section 5,
Checking and Adjusting
Reverse Drive System.
• No reverse motion should occur if
Wheels/Tines/PTO Drive Lever is not
held up in REVERSE. See Section 5,
Checking and Adjusting Reverse
Drive System for adjustment steps.
Do not use tiller unless properly
adjusted.
• Always return to NEUTRAL and let all
motion stop before shifting to
FORWARD or REVERSE.
CAUTION
The Forward Interlock Safety System is
designed for the operator’s safety. Do
not disconnect or attempt to defeat the
purpose of the system. If the system
malfunctions, immediately contact your
local authorized dealer or the
TROY-BILT Technical Service Depart-
ment for assistance. Do not use the
tiller or the PTO power unit until the
Forward Interlock Safety System is
functioning properly. Always test the
system before using the tiller or PTO
power unit.
DANGER
Keep away from rotating tines. Rotating
tines will cause injury.
WARNING
Cold Weather Operation
When temperatures fall below 40
o
F, do
the following steps to protect your
engine and transmission from damage:
1. Refer to the Engine Owner’s Manual
for motor oil specifications for cold
weather operation. Use winter blend
gasoline.
2. Warm up the engine before putting it
under a load.
3. Use winter-blend gasoline.
4. Use the correct weight gear oil in PTO
Power Unit transmission.
5. Warm up the transmission gear oil as
follows: With engine running, move
Wheel Speed Lever (Figure 4-2) to
FREEWHEEL (then block wheels so they
can’t roll), put Tines/PTO Clutch Lever
into DISENGAGE, then squeeze one of
the Forward Interlock Levers and shift
the Wheels/Tines/PTO Drive Lever to
FORWARD.
6. If wheels are frozen to the ground,
melt ice with warm water.
16
Section 4: Operation
6. When the tiller moves forward, relax
and let the wheels power the tiller along
while the tines dig. Walk behind and to
one side of the tiller. Walk on the side
that is not yet tilled (Figure 4-4). Use a
firm grip on the handlebars but keep your
arm relaxed.
IMPORTANT: Let the tiller move ahead at
its own pace. Do not push it ahead—this
reduces operator control and tilling effi-
ciency. Do not push handlebars down in
an attempt to dig deeper— this takes
weight off the wheels, reduces traction,
and causes the tines to try to propel the
tiller.
Stopping Forward Motion and Tines
1. To stop forward motion, tap
Wheels/Tines/PTO Drive Lever upward
into NEUTRAL. Then release the Forward
Interlock Levers. The wheels and tines
will stop and the engine will continue
running.
2. In an emergency, release all of the
control levers. This stops forward motion
and shuts-off the engine.
Moving the Tiller in Reverse
IMPORTANT: Do not till while in
REVERSE.
1. Shift the Tines/Wheels/PTO Drive Lever
(Figure 4-2) into NEUTRAL and move the
Wheel Speed Lever to the SLOW position.
2. Move Tines/PTO Clutch Lever (Figure
4-2) into DISENGAGE position.
3. Verify that the area behind you is clear.
4. Lift up the handlebars until the tines
are off the ground, then shift the
Wheels/Tines/PTO Drive Lever all the way
up and hold. You do not need to squeeze
the Forward Interlock Levers to use
reverse.
5. The unit immediately engages in
reverse. Periodically check behind you
while holding the handlebars up and the
Wheels/Tines/PTO Lever in its upper-most
position.
Stopping Reverse Motion
Release the Wheels/Tines/PTO Drive
Lever– the lever automatically returns to
the NEUTRAL position. This stops the
wheels immediately. (The Forward
Interlock Levers will not stop REVERSE
motion.)
To Stop the Engine
Move the engine Throttle Lever to the
STOP position. Then, on electric start
models, turn key to OFF. Remove the key
for safekeeping.
Making Turns
Turning the tiller is easy and just requires
practice. First find the balance point
between the engine and the tines by lifting
up the handlebars (Figure 4-5). Once you
find the balance point, then let the
powered wheels do the turning as you
push sideways on the handlebars in the
direction of the turn. Practice the turning
maneuver described here in a large open
area. Once comfortable turning the tiller,
you can then take it to the garden area.
1. At the end of a row, move the Wheels/
Tines/PTO Drive Lever (Figure 4-2) to
NEUTRAL position and reduce the engine
speed.
2. Move the Tines/PTO Clutch Lever
(Figure 4-2) into the DISENGAGE
position.
3. Resume forward operation, and lift
handlebars until tines are off the ground
(Figure 4-5). Find the balance point
between the engine and the tines. Then
push the handlebars in the direction of the
turn.
Be very careful to keep feet and legs
away from the tines (which should be dis-
engaged).
Let the powered wheels do the
hard work. The inside wheel will pivot in
place while the outside wheel drives the
tiller around in the direction of the turn.
NOTE: Use REVERSE if necessary to turn
in a limited space.

To Help Avoid Personal Injury or
Damage to Equipment:
• Be sure no obstacles are behind you
before operating the tiller in REVERSE.
• Disengage the tines, reduce engine
speed, and move the Wheel Speed
Lever to SLOW position before
operating in REVERSE. Avoid using
FAST wheel speed until you are
familiar with backing the tiller.
CAUTION
Figure 4-5: Turning the tiller.
Section 4: Operation
4. When the turn is complete, shift to
NEUTRAL and lower the handlebars.
Move Tines/PTO Clutch Lever back to
ENGAGE position and resume forward
operation.
Transporting The Tiller Around
Your Property
When the engine is running, the tiller’s
powered wheels make moving the tiller to
and from the garden easy. If the engine is
not running set the Wheel Speed Lever to
FREEWHEEL position to roll the tiller to
another location.
1. Place the Tines/PTO Clutch Lever in
DISENGAGE position.
2. Move Depth Regulator Lever down all the
way into the Travel setting.
3. If using engine power, move Wheel
Speed Lever to either SLOW or FAST, and
use the Wheels/Tines/PTO Drive Lever to
drive the wheels.
4. If the engine is stopped, move Wheel
Speed Lever to FREEWHEEL, and
manually push tiller.
Testing the Forward
Interlock Safety System
The Forward Interlock Safety System is
designed to shut the tiller engine off
immediately if you lose control and
cannot stop moving FORWARD by
shifting the Wheels/Tines/PTO Drive Lever
into NEUTRAL. When you release both
Forward Interlock Levers, they send
ground to the ignition system thereby
stopping the engine. Squeezing one or
both levers up against the handlebars
enables the ignition system; therefore,
you must squeeze at least one lever
whenever the Wheels/Tines/PTO Drive
Lever is engaged in FORWARD.
IMPORTANT: The interlock system also
prevents the engine from starting if the
Wheels/Tines/PTO Drive Lever is engaged
in FORWARD.
How to Check the Interlock System
The Forward Interlock System has an
electro-mechanical design, and so is
subject to normal wear and possible mal-
function. Check the system for proper
operation each time prior to using the
tiller or PTO power unit.
To test the Forward Interlock System:
1. Move tiller outside to level ground.
Remove any obstacles.
2. Check that the Forward Interlock wire
harness plug, at the bottom of the handle-
bars (Figure 4-6), is securely connected
to the receptacle on the top, right side of
the transmission.
3. Move Wheel Speed Lever (Figure 4-2)
to SLOW position and move Tines/ PTO
Clutch Lever to DISENGAGE.
4. Start engine as described under
Starting and Stopping the Engine, in this
section. Set engine throttle lever to
SLOW, and let engine warm up.
5. Squeeze and hold just one of the
Forward Interlock Levers against the
handlebar grip while moving the Wheels/
Tines/ PTO Drive Lever down to
FORWARD (Figure 4-3). As the tiller
moves forward, release the Forward Inter-
lock Lever briefly. The engine should
start to stall out if the interlock system is
working properly. If it does start to stall,
quickly squeeze the lever up against the
handlebar grip, and then return the
Wheels/ Tines/ PTO Drive Lever to
NEUTRAL. Repeat this test to check that
the engine begins to stall out when the
other Forward Interlock Lever is released.
6. If the engine does not begin to shut off
when either Forward Interlock lever is
released, shut the engine off, remove the
key (if electric start), and
do not operate
the tiller or PTO power unit until the
system has been repaired and is func-
tioning properly.
IMPORTANT:
To avoid possible damage
to the Forward Interlock Safety system,
do not use high-pressure sprays near the
wire harness receptacle or neutral plunger
assembly.
Loading and Unloading the Tiller
The following provides information on
tiller loading, unloading, and requirements
before loading and unloading the tiller.
Read the following instructions carefully
before attempting to load or unload your
tiller.
Before Loading or Unloading the
Tiller
• Ramps must be strong enough to
support the combined weight of the tiller
and handlers. They should provide good
traction to prevent slipping; they should
have side rails to guide the tiller along
the ramps; and they should have a
locking device to secure them to the
vehicle.
• Handlers should wear sturdy footwear
that will help to prevent slipping.
Figure 4-6: Plug and receptacle of
Forward Interlock Safety System
must be securely connected.
The Forward Interlock Safety System is
designed for the operator’s safety. Do
not disconnect or attempt to defeat the
purpose of the system. If the system
malfunctions, immediately contact your
local authorized dealer or the
TROY-BILT Technical Service Depart-
ment for assistance. Do not use the
tiller or the PTO power unit until the
Forward Interlock Safety System is
functioning properly. Always test the
system before using the tiller or PTO
power unit.
DANGER
To help avoid personal injury from
revolving tines, always put the
Tines/PTO Clutch Lever in DISENGAGE
position before transporting, loading, or
unloading tiller.
WARNING
18
Section 4: Operation
• Turn the vehicle’s engine off and apply
its parking brake.
• Position the loading vehicle so that the
ramp angle is as flat as possible (the
less incline to the ramp, the better).
Loading the Tiller
1. Use loading ramps that are strong and
wide enough to safely hold the weight of
the tiller and the operator combined—
your tiller weighs between 280 and 325
lbs.
2. Move the Tines/PTO Clutch Lever
(Figure 4-2) into DISENGAGE position.
3. Set the Depth Regulator lever (Figure
4-2) to the Travel position.
4. Move Wheel Speed Lever (Figure 4-2)
into SLOW position and reduce the
engine throttle speed.
5. Shift the Wheels/Tines/PTO Lever
(Figure 4-2) into FORWARD position and
follow the tiller up the ramps (Figure 4-7).
Check the wheels as you move the tiller
forward. Ensure that they move up the
center of each ramp.
6. Prevent tiller from rolling in vehicle.
Leave Wheel Speed Lever in FAST or
SLOW position, chock wheels with blocks
and tie down the tiller.
Unloading the Tiller
IMPORTANT: Never unload the tiller in
FORWARD drive. The tiller could tip
forward and expose you to the tines
(which should be disengaged as
instructed).
1. Use loading ramps that are strong and
wide enough to safely hold the weight of
the tiller and the operator combined—
your tiller weighs between 280 and 325
lbs.
2. Move the Tines/PTO Clutch Lever
(Figure 4-2) to DISENGAGE position.
3. Set the Depth Regulator Lever (Figure
4-2) to the Travel position.
4. Move Wheel Speed Lever (Figure 4-2)
to SLOW position and reduce the engine
throttle speed.
IMPORTANT: Look behind you before
you back down the ramp to ensure that all
is clear. While descending, keep checking
for obstacles behind you.
5. Move and hold the Wheels/Tines/PTO
Lever into REVERSE drive and back down
the ramps (Figure 4-8). Check the wheels
as you move the tiller backward. Ensure
that they move down the center of each
ramp.
Changing Speed Belts
Your tiller has two belt-driven speed
ranges – HIGH RANGE and LOW RANGE
– you pick one or the other by deciding
which set of pulley grooves to move the
forward belt into. By moving the belt
from one speed range into the other, in
combination with the FAST and SLOW
wheel speeds, you obtain a choice of four
different forward wheel speeds and two
different tine speeds.
Changing the belt from LOW range into
HIGH range (or back again) is a matter of
moving the belt from one set of pulley
grooves to a second set of pulley grooves.
This change is done quickly and without
tools (Figures 4-9 through 4-13).
When the tiller is moving in REVERSE, the
wheels are powered by a rubber reverse
disc, not by the belt. Therefore, you have
only two reverse speeds SLOW and FAST,
as set with the Wheel Speed Lever.
Table 4-1 shows the range of wheel and
tine speeds available when using the two
belt speed ranges and the FAST and
SLOW selections on the Wheel Speed
Lever.
Changing Belt From LOW Range
to HIGH Range
1. To avoid personal injury, shut off
engine, let all moving parts come to a
complete stop, then disconnect spark
plug wire from spark plug and move it
away from spark plug before making any
adjustments. Wait for the engine and
muffler to cool down.
2. Move Wheels/Tines/PTO Drive Lever
into NEUTRAL.

Section 4: Operation
3. Kneel on left side of tiller. To create
belt slack, reach over to right side of the
pulleys and push in at the center of the
belt with a finger. At the same time, use
your left hand to work the belt part-way
onto the lower-front transmission pulley
groove (Figure 4-10).
4. Go to the other side of the tiller to
finish seating the belt onto the pulley
groove.
5. Working from the left side of the tiller,
work the belt as much as possible onto
the top-front engine pulley groove (Figure
4-11).
6. Finish seating the belt from the right
side
of the tiller.
IMPORTANT: Proper belt tension is
important for good performance. See
Section 5,
Drive Belt Maintenance for
information on belt maintenance schedule
and procedures.
NOTE: If extra belt slack is needed to
move the belt, just raise the
Wheels/Tines/PTO Drive Lever up into
REVERSE. This lowers the engine pulley,
and creates more slack.
7. Check both sides of the high range
pulley grooves to verify that the belt is
properly seated.
Changing Belt From HIGH Range to
LOW Range
1. To avoid personal injury, shut off
engine, let all moving parts come to a
complete stop, then disconnect spark
plug wire from spark plug and move wire
away from spark plug before making any
adjustments. Let engine and muffler cool.
2. Move the Wheels/Tines/PTO Drive
Lever into NEUTRAL.
3. Stand on left side of tiller. Use your
right hand to hold the Wheels/Tines/PTO
Drive Lever up into REVERSE position.
Use your left hand to move the belt off
top-front engine pulley groove to top-rear
engine pulley groove (Figure 4-12).
4. Go to right side of tiller and finish
seating the belt.
5. Still holding the lever up in REVERSE
position, and working from the left side of
the tiller, move the belt from the lower-
front transmission groove to the lower-
rear transmission groove.
6. Go to the right side of the tiller and
finish seating the belt (Figure 4-13).
7. Check that the belt is fully seated in the
pulley grooves. Check this from both
sides of the tiller.
Choosing Wheel
and Tine Speeds
Your tiller has four FORWARD wheel/tine
speed combinations for handling a variety
of tilling tasks and gardening jobs. Exper-
iment with the tine depth, engine speed,
and wheel/tine speed and determine the
combination that provides the best
results. Here are some tips:
1. Advance the throttle lever so the engine
has sufficient power.
2. When tilling untilled or hard earth, do
not set the Depth Regulator too deep. The
tiller will buck and the engine will load
down.
3. You will know your settings are ideal
when the tines break-up the soil easily,
the engine does not labor, and your
progress is steady and smooth.
See Table 2,
Wheel Speed and Belt Range
Selection Guide for recommendations.

TABLE 2-4: WHEEL SPEED AND BELT RANGE SELECTION GUIDE
IMPORTANT — For correct wheel speed and belt range choices when using attachments or accessories
other than tines, read the Owner/Operator Manual provided with the attachment or accessory.
Let the tiller do the work
• While tilling, relax and let the wheels
pull the tiller along while the tines do
the digging. Walk on the side that is not
yet finished (to avoid making footprints
in the freshly tilled soil) and lightly, but
securely grip the handlebar with just
one hand (Figure 4-4).
• Avoid pushing down on the handlebars
in an attempt to force the tiller to dig
deeper. Doing so takes the weight off
the powered wheels, causing them to
lose traction. Without the wheels
helping to hold the tiller back, the tines
will attempt to propel the tiller – often
causing the tiller to skip rapidly across
the ground. (Sometimes, slight
downward pressure on the handlebars
will help get through a particularly
tough section of sod or unbroken
ground, but in most cases this won’t be
necessary.)
Tilling depths
• Avoid trying to dig too deeply too
quickly, especially when busting sod or
tilling soil that hasn’t been tilled for
some time.
Use shallow depth settings
(only an inch or two deep) for the first
passes through the garden area.
With each succeeding pass, adjust the
depth regulator to dig another inch or
two deeper. (Watering the garden area
a few days prior to tilling will make
tilling easier, as will letting the newly
worked soil set for a day or two before
making a final, deep tilling pass.)
• When cultivating (breaking up the
surface soil around plants to help
destroy weeds), use very shallow depth
settings to prevent injury to plants whose
roots often grow close to the surface. If
needed, lift up on the handlebars slightly
to prevent the tines from digging too
deeply. Cultivating on a regular basis not
only eliminates weeds, it also loosens and
aerates the soil for better moisture
absorption and faster plant growth.
Avoid tilling wet, soggy soil
Tilling wet soil often results in large, hard
clumps of soil that can interfere with
planting. If time permits, wait a day or
two after heavy rains to allow the soil to
dry before tilling. Test the soil by
squeezing it into a ball. If it compresses
too easily, it is too wet to till.
Tilling Tips
&
Techniques
21
To help avoid personal injury, be aware
that the tiller can unexpectedly bounce
up or jump ahead and propel away from
you if the tines strike hard or frozen
ground, or buried obstacles like large
stones, roots or stumps. Always use
the following precautions to help
maintain control of the tiller:
• Walk behind and to the side of the
tiller. Use one hand on the handlebars,
relaxing your arm but with a secure
hand grip.
• Use shallow depth regulator settings.
Till gradually deeper.
• Use slower wheel, tine and engine
speeds.
• Clear the tilling area of all large
stones, roots and other debris.
• Do not put downward pressure on the
handlebars. If needed, apply slight
upward handlebar pressure to keep the
tines from digging too deeply.
• Avoid contacting hard soil or sod at
the end of a row – reduce engine speed
and lift handlebars to raise tines out of
the soil.
• In An Emergency, stop tines and
wheels by moving Wheels/Tines/ PTO
Drive Lever to NEUTRAL. If you cannot
reach the lever or have lost control, Let
Go Of The Handlebars and All Controls.
WARNING
Section 4: Operation
22
Avoid making footprints
When possible, walk on the untilled side
of the unit to avoid making footprints in
the freshly tilled soil (Figure 4-4). Foot-
prints cause soil compaction that can
hamper root penetration and contribute
to soil erosion. They can also “plant”
unwanted weed seeds back into the
newly tilled soil.
Suggested tilling patterns
• When preparing a seedbed, go over
the same path twice in the first row,
then overlap one-half the tiller width
on the rest of the passes (Figure 4-
14). When finished in one direction,
make a second pass at a right angle as
shown in Figure 4-15. Overlap each
pass for best results (in very hard
ground it may take three or four
passes to thoroughly pulverize the
soil).
• If the garden size will not permit
lengthwise and then crosswise tilling,
then overlap the first passes by one-
half a tiller width, followed by succes-
sive passes at one-quarter width
(Figure 4-16).
• With planning, you can allow enough
room between rows to cultivate
(Figure 4-17). Leave room for the
hood width, plus enough extra room
for future plant growth.
Tilling on slopes
If you must garden on sloping ground,
please follow two very important guide-
lines:
1. Till only on moderate slopes, never
on steep inclines where footing is
difficult (review safety rules in the
“Safety” Section of this Manual).
2. We recommend tilling up and down
slopes rather than terracing. Tilling
vertically on a slope allows maximum
planting area and also leaves room
for cultivating.
IMPORTANT: When tilling on slopes,
be sure the correct oil level is main-
tained in the engine (check every one-
half hour of operation). The incline of
the slope will cause the oil to slant away
from its normal level and this can starve
engine parts of required lubrication.
Keep the engine oil level at the full point
at all times!
A. Tilling up and down slopes:
• To keep soil erosion to a minimum, be
sure to add enough organic matter to
the soil so that it has good moisture-
holding texture and try to avoid leaving
footprints or wheel marks.
• When tilling vertically, try to make the
first pass uphill as the tiller digs more
deeply going uphill than it does
downhill. In soft soil or weeds, you
may have to lift the handlebars slightly
while going uphill. When going
downhill, overlap the first pass by
about one-half the width of the tiller.
HINT: For best results, use the HIGH
belt range and SLOW wheel speed lever
position. See Changing Speed Belts in
this section for more information on
changing to high range.

Figure 4-16
To avoid serious personal injury or
damage to the equipment:
• Do not operate tiller on a slope too
steep for safe operation. Go slowly
on any slope. Make sure you have
good footing.
• Wear footwear that increases
stability and reduces slippage.
• Do not use FAST wheel speed
position when on sloped ground.
• Do not shift the Wheel Speed Lever
when heading up or down a slope. If
lever is accidentally moved to FREE
WHEEL position, the tiller could roll
out of control.
• To prevent engine damage due to oil
starvation (on slopes,the engine is
inclined and oil moves away from
surfaces that need lubrication), be
sure the correct oil level is main-
tained during all uphill/downhill
tilling operations. Check the level of
the oil in your engine after every one-
half hour of operation.
WARNING
23
B. Terrace Gardening:
• When a slope is too steep or too short
for vertical tilling, it may be necessary
to till across the slope and create
terraced rows. Terraces are rows that
are cut into the side of a slope, creating
a narrow, but flat area on which to
plant.
• On a long slope, you can make several
terraces, one below the other.
• Terraces should be only 2-to-3 feet
wide. Digging too far into the side of
the slope will expose poor subsoil that
is unproductive for plants.
• To create a terrace, start at the top of
the slope and work down. Go back and
forth across the first row as shown in
Figure 4-18.
• Each succeeding lower terrace is
started by walking below the terrace
you’re preparing. For added stability of
the tiller, always keep the uphill wheel
in the soft, newly tilled soil. Do not till
the last 12" or more of the downhill
outside edge of each terrace. This
untilled strip helps prevents the
terraces from breaking apart and
washing downhill. It also provides a
walking path between rows.
C. Tilling across slopes
without terracing
• If vertical or terracing gardening aren’t
practical for you, then you can till
laterally across a slope. We don’t
really recommend this method as it
can create unsure footing and invites
soil erosion.
• Study the terrain to make certain the
slope is not too steep for safe tilling.
If possible, make terraced rows or till
vertically.
• Move the belt into LOW belt range and
the Wheel Speed Gear Lever to SLOW
position. As in terrace gardening, start
at the top of the slope and overlap the
first pass by half the width of the tiller.
For added stability, keep the uphill
wheel in the soft, newly tilled soil. Each
succeeding terraced area is started by
walking
below the terrace you are
preparing (Figure 4-19).
Clearing the tines
The tines have a self-clearing action
which helps to eliminate most tangling
of debris. However, occasionally dry
grass, stringy stalks or tough vines may
become tangled.
Follow these procedures to help avoid
tangling and to clear the tines, if
necessary.
• To reduce tangling, set the Depth
Regulator deep enough to get
maximum “chopping” action as the
tines chop the material against the
ground. Also, try to till under crop
residues or cover crops while they are
green, moist and tender.
• While power composting, try swaying
the handlebars from side to side (about
6" to 12"). This “fishtailing” action
often clears the tines of debris.
• It may be necessary to remove the
debris by hand (a pocket knife will help
you to cut away the material).
Section 4: Operation

Before clearing the tines by hand, stop
the engine, allow all moving parts to
stop and disconnect the spark plug
wire. Failure to follow this warning
could result in personal injury.

Section 4: Operation
24
POWER COMPOSTING
Power composting means tilling under
and burying in the soil all manner of
organic matter such as crop residues,
leaves, grass clippings and cover crops.
This material will decompose during the
non-growing season and add important
natural nutrients to the soil.
Begin by composting crop residues such
as leftover vines, stalks, stems and
roots. Power compost these crop
residues as soon as they finish bearing.
The sooner this is done, the better, as
tender green matter is easier to till
under. Use the deepest depth regulator
setting possible without causing the
engine to labor or the tiller to jump
ahead.
Standing cornstalks of reasonable height
can be power composted (Figure 4-20).
Pushing over (but not uprooting) corn-
stalks will often make it easier for your
tiller to chop up the stalks. Keep the
tines clear of excessive tangling by “fish-
tailing” or frequently using reverse.
Make several passes, then return a few
days later to finish off any remaining
stubble.
After tilling under crop residues, add
more organic matter such as leaves,
grass clippings and even kitchen scraps.
When tilled into the soil, this organic
matter will decompose and add even
more important nutrients to the soil.
After power composting, you may want
to plant a “green manure” cover crop to
protect the soil during the off-season.
Grow a crop of clover, alfalfa,
buckwheat, peas, beans, rye grass,
grain, or kale and then till it into the soil
prior to the planting season.
Wide-Row Planting
The wide-row planting technique is
spreading seeds anywhere from 10
inches to 2 feet wide or more. As a
result, you can grow anywhere from 3 to
4 times (or more) produce in the same
space that is normally set aside for an
area that has narrow, single rows.
Wide-row planting automatically shades
the ground which keeps weed growth
down and also holds moisture in the
soil. And of course, harvesting is much
easier – everything is right at hand to be
picked. Preparing wide rows is easy —
after you prepare the seedbed and mark
off the rows with string, hand-broadcast
the seeds as if seeding a lawn (not quite
as much as lawn seed). Cover with soil
and tamp the area firmly with a hoe.
Tilling Under Corn
After corn is harvested, the stalks should
be tilled into the soil while still green.
Dry plants are more difficult to till under,
and the roots break loose too easily.
IMPORTANT: Do not pull the roots out
by hand or cut the stalks before tilling.
Stalks that are firmly anchored by their
roots are much easier for the tines to
chop, cut, and work under.
1. As you move forward into a row of
stalks, aim the tiller so that the stalks go
between the left wheel and the transmis-
sion case (Figure 4-19). Do not use the
right wheel because damage could occur
to the air cleaner, carburetor or throttle
linkage.
2. Each new pass should overlap the
previous pass by one-half the width of
the tiller.
3. Till as deeply as possible. Pull the
Depth Regulator all the way UP and
engage the lowest notch for deep tilling.
Use either LOW or HIGH belt range and
SLOW wheel speed gear position.
Let the tilled-in stalks decompose for a
week or so. Then till in the remaining
residue as deep as possible.
Soil Enrichment Idea
Trench Composting — Trench com-
posting is easy with the optional
Hiller-Furrower Attachment (Section
5). Dig a trench, put in all kinds of
organic matter, and cover with soil.
Earthworms and microbes will break it
down quickly.
Figure 4-20: Tilling under corn
stalks.
Tilling Tips
&
Techniques
When power composting, do not keep
the Depth Regulator Lever at a deep
setting if the tiller jumps or bucks.
If jumping or bucking occurs, move
the Depth Regulator Lever down to
one of the shallower settings and
then slowly increase the tilling depth
on later passes.
Failure to comply could result in loss
of tiller control, property damage or
personal injury.
WARNING
Your tiller is a self-contained PTO (Power
Take-Off) Power Unit that was shipped
with a tine attachment installed. The tine
attachment can be quickly removed and
replaced with other optional attachments.
The following instructions will familiarize
you with your PTO Power Unit. Please
read these pages carefully.
The following steps explain how to
remove and replace the tine attachment.
You will need a 3/4" wrench (minimum
12" long for leverage).
Removing Tine Attachment
1. Move the tiller to level ground.
2. Be sure the engine is stopped, the
electric start key is removed, and the spark
plug wire is disconnected and moved away
from spark plug.
3. Place a sturdy support under the
engine to prevent the engine from tipping
forward when the tine attachment is
removed (Figure 4-23).
4. Place the Wheels/Tines/PTO Drive Lever
into NEUTRAL (Figure 4-22).
5. Place Tines/PTO Clutch Lever in
DISENGAGE (Figure 4-22).
6. Place Wheel Speed Lever into FREE
WHEEL (Figure 4-22).
7. Loosen the two swing-out bolts (Figure
4-24) that connect the power unit trans-
mission to the tine attachment and swing
out the bolts (Figure 4-25).
HINT: Loosening swing-out bolts can be
difficult. Use an extra-long wrench for
leverage.
8. Tip the PTO power unit forward about
one inch with one hand while pulling the
tine attachment back (Figure 4-26). The
guide pin on the power unit will slide out
of the guide hole in the tine attachment
(Figure 4-27).

Owner’s Manual for installation and
operation instructions specific to that
attachment.
Installing the Tine Attachment
1. Move the two PTO Power Unit swing-
out bolts outward and slide the washers
up against the bolt heads.
2. Remove the support block from under
the engine and slowly roll the power unit
back next to the tine attachment. Place
the support block back under the engine.
3. Remove the dust cap (or protective
wrapping) from the dog clutch coupling
on the tine attachment.
4. Carefully align the guide pin on the
PTO Power Unit with the alignment hole
in the tine attachment and bring the two
units together (Figure 4-27).
5. Move the two swing-bolts into the
slots of the tine attachment. Alternately
tighten each bolt until they are tight
enough to make the concave washers flat.
The bolts must be very tight – if you have
a torque wrench, tighten each bolt to
between 70 and 80 ft.-lbs.
IMPORTANT: The swing-bolts must be
kept very tight to prevent damaging wear
to the dog clutch coupling, alignment pin
or the alignment hole. Check bolt
tightness every 2-1/2 operating hours.
6. Remove the engine support before
moving the tiller in a forward direction.

Maintenance
Before inspecting, cleaning or
servicing the machine, shut off engine,
wait for all moving parts to come to a
complete stop, disconnect spark plug
wire and move wire away from spark
plug. Remove ignition key on electric
start models.
Failure to follow these instructions can
result in serious personal injury or
property damage.
WARNING
Tighten Bolts and Nuts
Check for loose or missing hardware
every ten (10) operating hours. Failure to
tighten or replace fasteners can cause
poor performance, equipment damage or
oil leakage. See your Parts Catalog for
complete fastener descriptions.
Most hardware on your tiller is visible.
Pay particular attention to hardware
shown in Figures 5-1, 5-2, 5-3 and 5-3A.
1. Check the transmission pulley
mounting bolt (Figure 5-1). If the washer
behind the bolt head is loose, the bolt
needs tightening. To do this, first insert a
punch or thick screwdriver into the hole
next to the bolt and wedge the tool
against the side of the motor mount
casting. This immobilizes the pulley while
you tighten the bolt.
2. Check jam nut on left side of neutral
plunger assembly (Figure 5-2). If loose,
immobilize bolt head with one wrench and
use another wrench to tighten the nut.
3. Check the three rear bearing cap
screws under the depth regulator
mounting bracket (A, Figure 5-3). If any
is loose, it can cause an oil leak or drive
shaft end play.
4. Check the five bolts securing the tiller
housing cover to the left side of the trans-
mission (B in Figure 5-3). Gear oil can
leak from a loose housing cover. To
reach the bolts, remove the left side tine
holder. See
Bolo Tine Maintenance in this
Section for tine holder removal directions.
5. Check both swing-bolts (C, Figure 5-3)
that connect the power unit transmission
to the tine attachment. Both bolts should
be checked every 2-1/2 hours of
operation. If loose, wear can occur on the
locating pin on the power unit, and cause
enlargement of the locating hole in the
tine attachment. Using a torque wrench,
tighten these bolts to 70-to-80 ft.-lbs.
6. Check the locknut that fastens the
shifting linkage to the eccentric shifting
lever (D, Figure 5-3). Do not tighten the
locknut against the eccentric lever. It
should be very close to, but not touching
the lever.
7. Check the four bolts and nuts securing
left and right tine holders to the tine shaft
(Figure 5-3A).
IMPORTANT: Give screws or bolts that
go into the transmission housing a
coating of non-hardening gasket sealant
to prevent gear oil from leaking.
Tiller Lubrication
Proper lubrication of the tiller’s mechani-
cal parts is an essential part of good
maintenance. Lubrication should be done
after every ten (10) hours of operation.
Use ordinary motor oil (#30 weight or
lighter) where oil is specified. Use a
quality grease with a metal lubricant
where grease is recommended (regular
grease is acceptable). Do not over
lubricate. If there is a build-up of dirt,
remove the build-up and re-apply oil or
grease.

Failure to follow these instructions can result in serious personal injury or property damage.
WARNING
Section 5: Maintenance
IMPORTANT: Do not allow oil or grease
to contact the pulleys, drive belt or
reverse disc. This can cause the belt or
disc to slip on the pulleys.
Lubricate the numbered areas in Figures
5-4 and 5-5, as follows:
1. Oil the wheel shaft between the wheel
hubs and the transmission housing
(A, Figure 5-4).
2. Oil all pivoting and connecting points
on the Wheels/Tines/PTO Drive Lever and
the Wheel Speed Lever (B, Figure 5-4).
3. Grease the face of the belt adjustment
block (C, Figure 5-4).
4. Oil the Depth Regulator Lever,
including the spring in the mounting
bracket (D, Figure 5-4).
5. Oil the full length of the throttle cable
casing (E, Figure 5-4).
6. Oil threads on Handlebar Height Adjust-
ment Lever (F, Figure 5-4).
7. Grease left- and right-side engine
mounting bars at the top, the middle, and
bottom (G, Figure 5-4).
8. Grease the zerk grease fitting located
on the pivot point at the end of the Wheel
Speed Lever (H, Figure 5-4). If Wheel
Speed Lever has a grease fitting on pivot
assembly, apply 2-to-3 strokes of multi-
purpose grease at beginning and end of
tilling season.
9. Keep the PTO access area well-greased
(I, Figure 5-5). If the Tines/PTO Clutch
Lever becomes hard to move, squirt some
oil into its access hole, and work it back
and forth to disperse the oil.
Transmission Gear
Oil Maintenance
Checking for Oil Leaks
At 25-hour operation intervals, check the
tiller for oil leaks. Inspect for oil accumu-
lations on the tiller or the floor where it’s
stored.
A small amount of oil seepage or wetness
around a shaft opening or
cover is no cause for
alarm. But a heavy con-
centration of oil is more
serious. You should
tighten all bolts immedi-
ately, and replace any
worn seals or gaskets.
It may be impossible to
determine how much oil
has been lost, so check the
oil levels in the PTO trans-
mission and the tine
attachment before using
the tiller again. Add any
necessary gear oil.
Serious damage to the
transmission components
can result from operation
when gear oil levels are
low.
If tilling during very hot weather, the gear
oil may heat up and expand inside the
transmissions. To allow for this oil
expansion, both the power unit transmis-
sion and the tine attachment transmis-
sions have oil relief vents (Figure 5-6).
The vents allow small amounts of oil to
seep out.
If a serious leak is discovered, please
contact your authorized dealer or the
Factory Technical Service Department for
service advice.
Checking Gear Oil Levels
Every 30 hours of operation, check the
gear oil level in both the power unit trans-
mission and the tine attachment transmis-
sion. Operating them while low on gear
oil (even briefly) can cause serious
damage to internal components.
Preparation
1. The transmissions must be cool,
since hot gear oil expands and gives a
false reading.
2. The power unit transmission and the
tine attachment transmission must be
connected when checking (or adding)
gear oil.
Checking the Power Unit Oil Level
1. Move the tiller to level ground. Move
the Depth Regulator up so the tines rest
on the ground.
2. Use a 3/8" wrench to remove the oil
level check plug on the left side of the
transmission housing (Figure 5-7).

Failure to follow these instructions can result in serious personal injury or property damage.
WARNING
Section 5: Maintenance
3. If the oil level is correct, oil will seep
out of the check hole (allow extra time in
cold weather). If it does, the level is fine
and you should replace the check plug. If
no oil seeps out, see
Adding or Changing
Gear Oil
.
Checking the Tine
Attachment Oil Level
IMPORTANT: Two different gear oil
checking procedures for the tine attach-
ment transmission are described next.
Use the first procedure if the dipstick in
your tine attachment has only a ‘Check
Cold’ marking. Use the second procedure
if the dipstick has both cold and hot
markings at the end. First remove the
dipstick from the tine attachment trans-
mission (Figure 5-8) to see which type
dipstick you have. Then replace the
dipstick with markings on dipstick facing
to rear.
For Dipsticks With ‘Check Cold’ Marking
(Cold means 2 hours has passed since
the tiller was used.)
1. Move the tiller to level ground.
2. Pull the Depth Regulator Lever back,
then push it down all the way (to engage
its top notch).
3. Place a sturdy support under the
engine to prevent the tiller from tilting too
far.
4. Now slide three pieces of 2" x 4"
lumber underneath the drag bar– raising
the drag bar about 4-1/2" above ground.
This elevation allows an accurate “cold”
gear oil reading .
5. Wait two hours with tiller elevated
(allow more time if temperature is below
40
o
F).
6. Loosen and remove transmission
dipstick (Fig. 5-8). Wipe it clean with a
rag.
7. Hold dipstick so its markings face to
rear of tiller. Lower it straight down into
the sump hole to
touch the drive shaft
inside (Fig. 5-8). Don’t force or try to
thread it back in; an incorrect reading will
result.
8. Remove dipstick and check oil level. It
should be anywhere within the cross-
hatched area or even slightly above the
Max marking. If correct, replace dipstick
and remove the boards used as props.
9. If oil level was low, gear oil must be
added before using the tiller. See Adding
or Changing Gear Oil next.
For Dipsticks With Hot/Cold Markings
1. Move the tiller to level ground.
2. Pull the Depth Regulator Lever back,
then push it down all the way (to engage
its top notch).
3. Place a sturdy support under the
engine to prevent the tiller from tilting too
far.
4. Cold reading (preferred method):
(Two hours has passed since the tiller
was used.) Place a 2" x 4" board (on
edge) under the drag bar– raising the tiller
and drag bar about 3-1/2" above ground.
Hot reading: (Tiller was operated for
more than 30 minutes within the past
hour.) Do not use the wood prop to
elevate the tiller.
5. Follow Steps 4, 5 and 6 given for the
other dipstick type.
6. Remove dipstick and check level. It
should be within or above the “Cold”
range marking if taking a cold reading. If
taking a hot reading, the level should be
within or slightly above the “Hot” range.
7. If the level is incorrect, see Adding or
Changing Gear Oil.
Adding or Changing Gear Oil
For partial fill-ups (just a few ounces or
less), use SAE 140, SAE 85W-140, or SAE
80W-90 weight gear oil with an API rating
of GL-4 or GL-5. For full replacement,
use SAE 140 or SAE 85W-140 gear oil
with an API rating of GL-4 only. (At the
factory, SAE 85W-140 weight gear oil is
used.)
IMPORTANT: Do not use automatic
transmission fluid or engine oil. They are
too light in weight and will result in trans-
mission damage.
The gear oil does not need to be changed.
Do so only if you know, or suspect, it is
contaminated with dirt, sand or other
foreign particles.
Gear oil is available at authorized dealers
and most service stations, power
equipment centers, or farm/heavy
equipment outlets.
Capacities: Power unit transmission
holds approximately 60 ozs.; Tine Attach-
ment transmission holds approximately
12-1/2" ozs.

Section 5: Maintenance
Adding Gear Oil to the
PTO Power Unit Transmission
1. Do steps 1 and 2 of Checking the
Power Unit Oil Level on page 32.
2. Using a 3/4" wrench (or socket),
remove the bolt securing the handlebar
base to the top of the transmission (prop
the handlebars first to prevent them from
falling).
Then, unplug the Forward Interlock wire
harness receptacle at the bottom of the
handlebars. Set the handlebar base and
bolt aside on a clean surface. The bolt
hole in the top of the transmission is the
gear oil fill hole (A, Figure 5-9).
3. Slowly pour gear oil through a clean
funnel into the transmission. Stop when
gear oil begins to flow from the oil level
check hole on the left side of the trans-
mission (B, Figure 5-7).
4. Reinstall the oil level check plug.
Tighten it securely.
5. Reinstall the handlebars using the
mounting bolt previously removed. Align
the handlebars so they point straight
backwards, not at an angle. Then tighten
the mounting bolt securely.
6. Reconnect the Forward Interlock wire
harness to the receptacle. Be certain it’s
secure.
7. Test operation of the Forward Interlock
Safety System. See Section 4 for a
procedure.
Draining and Filling the
PTO Power Unit Transmission
1. Place a shallow pan under the trans-
mission gear oil drain plug (B, Figure
5-9).
2. Remove the oil level check plug (Figure
5-7) with a 3/8" wrench. This vents the
transmission for faster oil draining.
3. Using the 3/8" wrench, remove the
drain plug (B, Figure 5-9). The gear oil
will drain quite slowly since it is thick.
After about two quarts have drained, tilt
the tiller forward so any oil at the rear of
the transmission will drain out.
4. Clean the drain plug threads, put non-
hardening gasket sealant on the threads,
and reinstall plug.
5. Refill the transmission with the correct
amount of gear oil before operating the
tiller again. When oil seeps from the oil
level check hole, the right amount of gear
oil has been added. Replace all plugs.
Adding Gear Oil to the Tine
Attachment Transmission
1. Select the right Depth Regulator Lever
setting:
a. If filling an empty transmission, raise
the Depth Regulator Lever so tines
are on the ground.
b. If topping off the gear oil, move Depth
Regulator Lever down to engage its
top notch.
2. Remove dipstick from tine attachment
(Figure 5-8).
3. Slowly add gear oil in the dipstick hole.
Add 1/2-ounce at a time to avoid overfill-
ing. It takes about 12-1/2 ounces.
4. Take dipstick readings frequently. Stop
when oil reaches “Cold” range marking on
dipstick. Replace dipstick securely.
Draining and Filling the Tine
Attachment Transmission
1. The tine attachment transmission is
not equipped with an oil drain plug. To
drain just a small amount of gear oil,
remove the dipstick and tilt the attach-
ment forward (first uncoupling it from the
Power Unit).
2. For complete drainage, remove the left-
side tine assembly (refer to Bolo Tine
Maintenance for instructions), then
remove just one of the lower screws from
the tiller housing cover (Figure 5-10). To
speed drainage, remove the tine attach-
ment dipstick to vent transmission.
NOTE: If you find a plastic washer on the
cover screw you remove, discard the
washer. There is no need to install a
replacement washer.
3. Once all gear oil has drained, reinstall
the housing cover screw securely (first
coat its threads with non-hardening
gasket sealant).
4. Be certain to refill the transmission
with the correct amount of gear oil before
operating the tiller again.

Section 5: Maintenance
Drive Belt Maintenance
Measuring and Adjusting
Drive Belt Tension
On a new tiller (or if a new belt is
installed), the belt tension will probably
need to be adjusted after the first two (2)
hours of operation. Thereafter, check belt
tension every ten (10) operating hours.
Maintaining the right tension is important
to good tiller performance and long belt
life. If too loose, the belt will slip on the
pulleys, and be unable to deliver full
power to the wheels and tines. A loose
belt will also wear prematurely.
While checking belt tension, also inspect
the belt for cuts, cracks, deterioration,
etc. Don’t continue using a belt that isn’t
in good shape. You’re sacrificing tiller
performance by doing so.
Tips on keeping the drive belt in top
condition include:
• Always put the Wheels/Tines/PTO Drive
Lever in NEUTRAL when the tiller is not in
use.
• Keep tension adjusted correctly.
• Don’t “speed shift” when moving the
Wheels/Tines/PTO Drive Lever between
FORWARD and REVERSE.
How to Measure Belt Tension
1. Before taking a measurement, be sure
the linkages and pivot points on the
Wheels/Tines/PTO Drive Lever are clean
and lubricated. If there is any binding,
you won’t get true measurements. Also,
you’ll need the belt adjustment tool you
received with your new tiller (Figure
5-11).
2. Move the Wheels/Tines/PTO Drive
Lever fully down to the FORWARD
position. The clutch roller at the bottom
of the lever should be positioned under-
neath the belt adjustment block (Figure
5-12). Don’t let the clutch roller move
during the next few steps. If it moves,
you’ll get a false belt tension reading.
3. The belt tension is correct if the front
of the clutch roller is 1/4"-to-5/16" away
from the face of the upright bracket that
holds the adjustment block in place
(Figure 5-12). To measure this distance:
a. Without moving the clutch roller, try
inserting the 1/4"-thick, slotted end
of the belt adjustment tool in
between the roller and the upright
bracket. (The flat edge of the tool
must be facing the roller.) Refer to
Figure 5-13.
b. If only the slotted portion of the tool
will fit, the belt tension is correct.
c. If the slotted part of the tool will not
fit in, the belt is too loose.
d. If the full thickness (5/16") of the
tool easily fits in, the belt is too
tight.
4. If the belt tension is correct, move the
Wheels/Tines/PTO Drive Lever back to
NEUTRAL.
How to Adjust Belt Tension
1. As described in the following steps,
drive belt tension is adjusted by moving
the adjustment block up or down.
Moving it down will tighten the belt;
moving it up loosens the belt.
HINT: The distance the block moves
approximately equals the distance the
roller moves.
In most cases, the clutch roller will not
have been very far out of position, so the
adjustment block will only need to be
moved slightly (up or down).
2. Move the Wheels/Tines/PTO Drive
Lever to NEUTRAL position. The clutch
roller will come to rest anywhere on the
face of the belt adjustment block,
depending upon drive belt length and
current belt tension adjustment.
Figure 5-12: Shift into FORWARD
and measure distance between
roller and upright bracket using the
belt adjustment tool.
Figure 5-11: Use this belt adjust-
ment tool to measure and adjust
drive belt tension.

3. Insert the belt adjustment tool through
the hole in the side of the adjustment
block, spacing the ends of the tool equally
on both sides (Figure 5-14). Rotate the
tool so the slotted end faces down.
4. Place the Wheels/Tines/PTO Drive
Lever in FORWARD position. The arms of
the clutch control yoke will be resting on
the belt adjustment tool and the clutch
roller should be engaged slightly beneath
the adjustment block (Figure 5-15).
5. Use one hand to hold the drive lever in
FORWARD while using a 9/16" wrench to
loosen (don’t remove) the bolt at the back
of the belt adjustment block (Figure 5-16).
The adjustment block should be free to
move either up or down.
6. Push the drive lever down if the belt
needs tightening. Pull the lever up if the
belt needs to be loosened. Hold the drive
lever in place and tighten the bolt in the
adjustment block firmly.
7. Let go of the drive lever and remove
the belt adjustment tool from the hole in
the adjustment block.
8. Check the tension on the belt by
following the previous instructions “How
to Measure Belt Tension.”
NOTE: If the adjustment block is all the
way down and the measurement between
the clutch roller and the bracket is less
than 1/4", then a new drive belt is needed.
Replacing the Drive Belt
Removing the Belt
1. Move Wheels/Tines/PTO Drive Lever to
NEUTRAL position.
2. While kneeling on the right side of the
tiller, create slack in the belt by reaching
over to the left side of the pulleys and
pushing in on the center of the belt with
your finger.
3. Use your right hand to move the belt
down and away from the lower pulley, in
the direction of the engine (Figure 5-17).
4. Push the belt upward to create slack in
the belt (Figure 5-18).
5. Lift the top half of the belt up and over
the upper pulley and the rubber reverse
disc, moving it in front of the reverse disc
(refer to Figure 5-19).
6. Push the Wheels/Tines/PTO Drive
Lever down into the FORWARD position.
This increases the distance between the
upper and lower pulleys. Next, lift and
pull the entire belt out between the pulleys
(Figure 5-20).
Replacing the Drive Belt
1. Place Wheels/Tines/PTO Drive Lever in
FORWARD position.
2. Squeeze the belt in the middle and
insert one end in between the pulleys
(Figure 5-20).

lower pulley’s grooves.
HINT: A blunt object, like a ruler, can
help you push the belt downward if
needed.
4. Move the top half of the belt up and
over the rubber reverse disc, but do not
seat it in either of the grooves in the top
pulley.
5. Place the Wheels/Tines/PTO Drive
Lever in NEUTRAL.
6. Move the top half of the belt into the
HIGH Range groove (groove closest to
the engine) on the top pulley (Figure
5-21).
7. Move the bottom half of the belt into
the HIGH Range groove of the lower
pulley (groove closest to engine— Figure
5-21). If extra slack is needed, hold up
Wheels/Tines/PTO Drive Lever while
moving the belt. Verify the belt is seated
properly on the pulleys.
8. To move the belt to the LOW Range
position, see Changing Belt Speeds in
Section 4.
9. After installing the belt, check and
adjust for correct belt tension as
explained previously.
Reverse Drive
System Maintenance
These instructions explain how to inspect,
replace or adjust the various reverse drive
components.
But first, here’s how the reverse drive
system works: When you raise the
Wheels/Tines/PTO Drive Lever up in
REVERSE position, this lowers the rub-
berized reverse disc (it’s attached to the
engine drive pulley) until this rotating disc
contacts the transmission drive pulley.
The friction between the rotating reverse
disc and the transmission pulley causes
the transmission drive shaft to be
powered in a counterclockwise direction
(as viewed from the operator’s position
behind handlebars). The drive shaft then
turns the wheels and tine shafts in a
reverse direction.
Reverse Disc Inspection
The reverse disc is made of steel with a
special, long-lasting rubber compound
bonded to the disc rim. Since this is a
wearing part, it should be inspected after
every 30 operating hours.
1. Measure the width of the outside edge
of the disc as shown in Figure 5-22.
Replace the disc before the rubber edge
wears to a thickness of 1/8" or less.
Failure to do so could cause the steel
underneath the rubber to damage the
transmission pulley.
2. Look for big cracks or missing chunks
of rubber from the disc. If so damaged,
the disc should be replaced immediately.
IMPORTANT: Extend the life of the
reverse disc by always pausing in
NEUTRAL before shifting between
FORWARD and REVERSE. Also – the
reverse disc is not suited for continuous
or sustained reverse operation. Use
reverse sparingly.
Figure 5-21: Seat belt in upper
pulley, then in lower pulley (High
Range position shown).
Figure 5-20: Shift into FORWARD
and remove the belt.

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come
to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition
key, if so equipped.
Failure to follow these instructions can result in serious personal injury or property damage.
WARNING

Replacing the Reverse Disc
Follow these steps to replace the reverse
disc. (If your tiller has a Bumper Attach-
ment mounted, it must be removed first.)
Removing the Reverse Disc
1. Move Wheels/Tines/PTO Drive Lever in
NEUTRAL position.
2. Wedge a 5/16"-thick board between top
of engine pulley (avoid contacting reverse
disc) and cast iron housing next to it.
This immobilizes pulley.
3. Use a 9/16" wrench to loosen the
mounting bolt shown in Figure 5-23.
Remember to immobilize the pulley with
the wood wedge while loosening the bolt.
If necessary, pry the disc from the pulley
with the tip of a screwdriver. Back the
bolt out as far as possible. Then angle
the disc a little to remove it. Bring the
bolt and lockwasher along with the disc.
Installing a New Reverse Disc
1. Do steps 1-through-3, described previ-
ously, in reverse.
2. Tighten mounting bolt securely, and
check for correct operation — see
Checking and Adjusting Reverse Drive
System
.
Checking and Adjusting
Reverse the Drive System
When the Wheels/Tines/PTO Drive Lever
is moved up into REVERSE, the engine
and engine mount move down to press
on the reverse adjustment bolt (Figure 5-
24). This action compresses the reverse
spring and plunger assembly, requiring
you to hold the lever up in REVERSE.
When you release the lever, the spring
automatically pushes the lever back into
NEUTRAL position.
The spring and plunger assembly is
designed to prevent the reverse disc from
making contact with the transmission
pulley until you shift into REVERSE.
When the lever is in NEUTRAL, the switch
body on the bottom of the engine mount
tab should be resting squarely on top of
the reverse adjustment bolt (Figure 5-24).
The reverse adjustment bolt can be
adjusted up or down to correct a number
of reverse drive operating problems, as
explained next.
Checking and Adjusting Reverse Disc
1. Verify that linkages for
Wheels/Tines/PTO Drive Lever are lubri-
cated with oil and engine mount bars and
belt adjustment block are lubricated with
grease. (See
Tiller Lubrication in this
section.)
2. Place Wheels/Tines/PTO Drive Lever in
NEUTRAL. Briefly pull out engine recoil
start rope while watching reverse disc.
The disc should turn, but lower pulley
should not (Figure 5-25). If reverse disc
turns lower pulley, or if it is located closer
than 3/16" to the pulley, reverse adjust-
ment bolt should be adjusted upward (see
instructions that follow). Moving adjust-
ment bolt upward will also solve problem
of a tiller that goes into REVERSE on its
own.
3. Use your left hand to hold
Wheels/Tines/PTO Drive Lever up in
REVERSE, while briefly pulling out engine
start rope. The reverse disc should turn
lower pulley (see Figure 5-26). If not, or
it requires a lot of pressure to hold lever
up in REVERSE, then reverse adjustment
bolt must be adjusted downward. When
correctly adjusted, the Wheels/Tines/PTO
Drive Lever should pop out of reverse
when the lever is released, but not require
exceptional effort to hold it up in reverse
position.
4. Shift the Wheels/Tines/PTO Drive Lever
to REVERSE and then let it go. The lever
should return to NEUTRAL. If not, the
reverse adjustment bolt will have to be
adjusted upward.

Adjusting Reverse Drive:
1. Place Wheels/Tines/PTO Drive Lever in
FORWARD position.
2. On left side of tiller, put a 1/2" wrench
on the plunger retaining bolt and another
1/2" wrench on the jam nut next to it
(Figure 5-27). While holding the bolt
steady, loosen the jam nut (counterclock-
wise) until it touches the bolt head.
3. Turn the bolt in until it tightens against
the plunger inside the spring. The bolt
must be tight to prevent plunger from
turning – but
be careful not to overtighten
and break the bolt.
4. Place a 7/8" wrench on the head of the
reverse adjustment bolt and a 9/16"
wrench on the jam nut below it (Figure 5-
28). Hold the bolt steady while loosening
the jam nut three or four turns.
5. Move the Wheels/Tines/PTO Drive
Lever to NEUTRAL. The switch body on
the bottom of the engine mount tab
(Figure 5-24) should be resting squarely
on top of the reverse adjustment bolt, and
the reverse disc should be at least 3/16"
away from the transmission drive pulley.
If the reverse disc is any closer than this,
raise the reverse adjustment bolt (turn it
counterclockwise).
6. Check that reverse disc is at least 3/16"
away from transmission drive pulley.
Then hold reverse adjustment bolt steady
with one wrench while tightening jam nut
with a second wrench (Figure 5-28).
7. Place a chalk or pencil mark on the top
edge of the plunger retaining bolt. Now,
while watching the mark, loosen the bolt
3/4-turn (Figure 5-29). Do not exceed a
3/4 turn (this would disengage the bolt
from the locking groove in the side of the
plunger).
8. Hold the plunger retaining bolt steady
with a wrench while tightening the jam
nut against the side of the plunger housing
(Figure 5-27).
9. Check the action of the reverse disc as
explained previously.
IMPORTANT: If the above adjustments
have not corrected an improperly working
reverse drive, contact an authorized
dealer or Factory Technical Service
Department for assistance.
Bolo Tine Maintenance
Checking Tines for Wear
Inspect the tines for wear or damage after
every 30 operating hours. The rate of
wear depends upon hours of use and soil
conditions. With use, the tines get
shorter, narrower and more pointed
(Figure 5-30). If badly worn, they lose the
ability to till deeply.
Worn tines leave an ever-increasing gap
in the middle of a tilled row. The normal
gap is 3" between the tine tips – replace
the tines when the gap widens to 5"
(Figure 5-31).
Tines can be replaced individually or as a
complete set. See replacement instruc-
tions that follow.
Figure 5-27: Hold bolt steady while
loosening or tightening jam nut.

2. Gently tilt the tiller forward until the
engine rests on the ground.
3. Raise the hood flap at the back of the
tiller and tie it up with string.
4. Before removing a tine, note in which
direction the bent tip points. The new tine
must be installed in the same direction.
5. Use two 9/16" wrenches to remove the
two bolts and nuts securing the tine to the
tine holder plate (Figure 5-32). Use pene-
trating oil on the hardware if it is rusted or
hard to remove.
6. Mount the new tine exactly the way the
old tine was positioned. (The sharp edge
of the tine, which enters the soil first, must
face forward when above the tine shaft.)
Replace the bolts and nuts and tighten
them securely.
Removing and Replacing A Tine
Holder Assembly
The 16 Bolo Tines are mounted eight per
side on left-side and right-side tine
holders. Here’s how to replace the tines
and holders as
assemblies.
Removing Tine Holder Assembly
1. Follow steps 1-through-3 in Single
Tine Replacement above.
2. Identify the tine holders as left-side
and right-side holders – they must be
replaced on the same side from which
they were removed. Use a piece of chalk
or a grease pencil to mark them L and R
.
3. Remove the two bolts and nuts
securing each holder (Figure 5-33).
4. Use a soft mallet to drive the holder
off the tine shaft. (Use a heavy hammer
and block of wood to knock off the immo-
bilized tine holder.)
5. When the holder is off, clean all dirt
and debris from the shaft and the holder.
Apply fresh grease to the tine shaft.
Replacing Tines Holder Assembly
1. Replace the holder so the sharp tine
edges face
forward (toward front of tiller).
Tap tine holder back on the tine shaft.
2. Grease the threads on the mounting
bolt(s). Install and tighten the bolt(s)
securely.

WARNING
• The tines or tine hood edges may be
sharp. Wear thick gloves to protect
your hands.
• Wear safety goggles to protect your
eyes. When loosening hardware, do
not hit a wrench with a metal tool– this
could shatter the tool or wrench,
sending metal particles into your eyes.
WARNING
38
Tine Shaft Maintenance
After every 10 operating hours, remove
the left- and right-side Bolo Tine holders
and clear away dirt and debris that have
accumulated on the tine shaft or inside
the tine holders. Please follow this main-
tenance recommendation, as debris can
cause premature wear to the tine shaft
and its oil seals. Refer to the previous
tine holder removal instructions. After
cleaning away any debris and removing
old grease from the tine shaft, apply fresh
grease to the tine shaft.
Tire and Wheel Maintenance
Check tire air pressure every 30 operating
hours. The recommended pressure for
tilling is 10-to-20 psi (pounds per square
inch). Both tires should be inflated
equally. (Unequal pressure can cause the
tiller to pull to one side.)
Removing the Wheels
Each wheel is secured by a roll (spirol)
pin that passes through the wheel hub
and the wheel shaft. Drive the roll pin out
to remove a wheel.
1. Prop the transmission up with a sturdy
block to raise the wheel you want to
remove off the ground.
2. Move the Wheel Speed Lever to either
SLOW or FAST position to prevent the
wheels from turning.
3. Use a 5/16" drift pin (or a blunt point
16-penny nail) to drive the roll pin free.
Engine Oil Maintenance
Check the engine oil level before starting
the engine each day and after each 5
hours of continuous operation. Running
the engine when it is low on oil will
quickly ruin the engine.
It is recommended that you change the oil
every ten (10) operating hours and even
sooner when operating in extremely dirty
or dusty conditions. Refer to the separate
Engine Owner’s Manual for detailed
service instructions.
Air Cleaner Maintenance
The engine is equipped with a dual
element air cleaner that filters the air
twice before it enters the carburetor to
mix with the fuel.
The engine air cleaner filters dirt and dust
out of the air before it enters the carbure-
tor. Operating the engine with a dirty,
clogged air filter can cause poor perfor-
mance and damage to the engine. Never
operate the engine without the air cleaner
installed. Inspect and service the air
cleaner more often if operating in very
dusty or dirty conditions.
It is critical that the filters be kept clean
and properly installed at all times. See
the location of the air cleaner assembly on
your engine by referring to Figure 5-39 or
Figure 5-40.
Refer to the engine manufacturer’s litera-
ture supplied with your tiller for complete
air cleaner service and maintenance infor-
mation.
Throttle Cable Maintenance
The throttle lever settings are factory-
adjusted, so unnecessary adjustments
should not be made. However, if the
engine does not start or stop, or respond
immediately to various throttle lever
settings, then adjustments may be
necessary. Please refer to the engine
manufacturer literature supplied with your
tiller for specific adjustment instructions.
Ignition System Maintenance
Your engine is equipped with electronic
ignition. It does not have a condenser or
points, so there is no need to perform any
regular tune-up maintenance on this
system other than adjusting or replacing
the spark plug.
Spark Plug Maintenance
The spark plug must be in good condition
for proper engine operation. Remove and
inspect the plug every 50 operating hours
or annually, whichever occurs first.
The correct electrode gap is .030". Check
the gap with a feeler gauge. Do not use a
spark plug if the porcelain is cracked, the
electrodes are pitted or burned, or if other
visible damage is present.
NOTE: Do not wire brush or sandblast the
spark plug to clean it – loose particles
can enter the engine, causing damage!
To replace the plug, first tighten it
securely by hand, then use a spark plug
wrench to tighten the plug an extra 1/4
turn.
Battery Care and Maintenance
The battery is sealed and is maintenence-
free. Acid levels cannot be checked.
• Always keep the battery cables and
terminals clean and free of corrosive
build-up.
• After cleaning the battery and
terminals, apply a light coat of
petroleum jelly or grease to the
terminals and cover both terminals
with the rubber boots.
Section 5: Maintenance
Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come
to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition
key, if so equipped.
Failure to follow these instructions can result in serious personal injury or property damage.
WARNING
Wear safety goggles when driving the
roll pin into or from the wheel hub to
protect your eyes from the possibility of
flying metal particles.
WARNING
39
When removing the battery, always dis-
connect the negative (-) cable first
followed by the positive (+) cable. Re-
verse this procedure when reinstalling
the battery.
WARNING
Storing Your Tiller
When your tiller won’t be used during the
off-season, prepare it for storage with the
following steps:
1. Clean the tiller and engine.
2. Do routine tiller lubrication and check
for loose hardware.
3. Protect the engine from deterioration
or damage by referring to the engine
storage instructions in your engine
manual literature.
4. When engine is still warm, drain oil
from engine crankcase. Refill with fresh
motor oil.
5. Protect internal cylinder against rust by
removing spark plug and pouring one
ounce of clean engine oil into spark plug
hole. Then slowly pull out recoil start
rope 2 or 3 times to distribute oil inter-
nally. Replace spark plug, but do not
reconnect plug wire. Pull rope until resis-
tance is felt — let rope rewind.
6. Charge battery (electric start option).
Store battery in cool, dry location.
7. Move Wheels/Tines/PTO Drive Lever to
NEUTRAL position. Keep tiller in a clean,
dry area.
8. Never store tiller with fuel in fuel tank
in an
enclosed area where gas fumes
could reach an open flame or spark, or
where ignition sources are present (space
heaters, hot water heaters, furnaces, etc.).
Inspecting Forward Interlock
Wiring System
Check the Forward Interlock wiring
system every ten (10) operating hours,
for tight connections and to see that the
insulation on the wires is unbroken (to
prevent the system from shorting out).
1. Check insulated wire harness from
lower ends of handlebars to wire harness
connector on top, right side of transmis-
sion cover. Be sure connector is secure.
2. Check insulated tubing from connector
to cast iron motor mount/belt shroud.
3. Check the wire leading from the tubing
over to the switch assembly mounted on
top of the tab on the cast iron motor
mount–belt shroud. Also check the
second wire that leads to the throttle
cable mounting bracket on the right side,
forward portion of the engine.
Testing the Forward
Interlock Wiring System
The wiring circuit for the Forward
Interlock Safety System is designed to
ground out the engine’s ignition system.
There are three switches in the circuit
which, when open, let the engine run.
One switch is on the neutral plunger tab
of the cast iron motor mount. This switch
is open whenever the Wheels/Tines/PTO
Drive Lever is in NEUTRAL or REVERSE
positions. The other two switches are
located inside the handlebars, directly
above the two Forward Interlock Levers.
The switches are wired so when squeezed
(open) the engine will run. There is a
fourth switch located in the wiring
harness connector on the top, right side
of the transmission cover. It warns you if
the connection is not mated by not letting
the engine run while the Wheels/Tines/PTO
Drive Lever is in FORWARD.
1. A broken or disconnected wire could
let the engine run without you having to
press one of the Forward Interlock Levers.
2. A bare wire touching tiller or engine
metal could ground out the engine’s
ignition.
3. A switch that has failed allows the
engine to run. Or it may prevent the
engine from running.
Refer to the
Troubleshooting section if
your Forward Interlock Safety System is
not operating correctly.
Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come
to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition
key, if so equipped.
Failure to follow these instructions can result in serious personal injury or property damage.

• Drive belt may be too tight. Raise belt
adjustment block a little (Sect. 5).
• Clutch pawl spring at end of lever may be
overstretched. Install new spring.
B. Lever hard to shift into REVERSE–
• Check reverse disc for wear (Sect. 5).
• Check adjustment of reverse disc and/or
reverse spring and plunger assy. (Sect. 5).
• Clean and re-lubricate motor mount bars,
belt adjustment block and linkages on lever
(Sect. 5).
C. Tiller stays in REVERSE when lever is
released–
• Lubricate motor mount bars, belt adjust-
ment block and linkages on lever (Sect. 5).
• Check adjustment of reverse spring and
plunger (Sect. 5). If problem persists,
contact Technical Service Department.
D. Lever sticks in FORWARD–
• Lubricate motor mount bars, belt adjust-
ment block, and linkages on lever (Sect. 5).
If problem continues, contact the Technical
Service Department.
E. Lever hard to shift into FORWARD–
• Follow advice for Problem 1-D. Also check
for possible bent motor mount bar that could
be binding in engine mount holes.
2 Wheel Speed Lever:
A. Lever hard to shift, or sticks in FAST or
SLOW wheel gear positions–
• Lubricate eccentric lever at rear of power
unit transmission (Figure 5-43). If rust is
present, use penetrating oil and work
eccentric lever back and forth by hand.
• Lubricate linkage to Wheel Speed Lever to
eccentric lever (Figure 5-43).
• Clutch inside transmission may be binding.
Disconnect linkage from eccentric lever and
work eccentric lever by hand. If difficult or
impossible to move, it may be due to a
damaged keyway on the wheel shaft.
Contact Technical Service Department.
• Lubricate washers and castle nut on pivot
of lever. If necessary, remove roll pin and
back nut off 1/6th turn. Replace roll pin and
test the movement.
• Apply grease to zerk fitting (if so equipped)
with grease gun until grease appears around
washers.
B. Lever shifts into FAST wheel gear, but
not into SLOW wheel gear–
• Connecting rod at end of lever might be
backwards, or bent in toward transmission
housing and hitting it. Other shifting linkage
might be bent. Straighten or replace linkage
(Figure 5-43).
• Clutch inside transmission may be binding
(Problem 2-A).
C. Lever moves freely, but won’t shift in or
out of gear–
• Eccentric shifting pin inside transmission
may be broken (rare) or worn. Disconnect
linkage from eccentric lever and try moving
eccentric lever by hand (Figure 5-43). If
lever moves easily, contact the Technical
Service Department.
3 Wheels and Tines Won’t Turn:

Troy-Bilt
®
PTO Log Splitter
290-258-081
The Troy-Bilt
®
PTO Log Splitter provides
you with a convenient and easy means of
splitting about a half a cord of wood per
hour when working alone. When
connected to the PTO Power Unit, the
tiller’s engine runs the splitter’s hydraulic
pump, providing you with 13 tons of
steady, unhurried and predictable splitting
force.
As an added benefit, the power-driven
mobility provided by the PTO Power Unit
allows you to move the splitter to and
from your wood pile, over to a neighbor’s
place, or along the woodpile to a fresh
supply of logs.
Features include a 15 second splitting
cycle; can handle log sizes up to 26" long;
a two-stage hydraulic pump that automat-
ically shifts into low gear to provide four-
times greater pressure when needed;
slim-cut wedge design for splitting green,
stringy wood; and an auto-control valve
for automatic return stroke.
Dozer/Snow Blade Attachment
290-259-081
In the winter, moves up to one foot of
light snow (or 6"-to-8" of heavy snow); at
other times use it to move or spread
sand, gravel, loose dirt, grain, sawdust,
etc. Attaches easily to the front of the
Wrap-Around Bumper Guard. Set the
blade to several angles. Weighs 41-lbs.;
measures 15" x 32".
Row Marker Attachment
290-257-081
Do you like very straight, even, neat rows
in your garden? If so, the Row Marker is
a must attachment. Hooks quickly to the
Hiller/Furrower attachment– eliminates
the need for string, stakes, measuring
tape, etc. You’ll like the straight rows it
helps you make if you lay out furrows, dig
compost trenches, or make raised beds.
The Row Marker extends from 28"-to-
49
3
⁄
4", letting you vary the width between
rows to suit the crop you’re planting.
V-Sweep Cultivator
290-260-081
The V-Sweep Cultivator is a specialized
tool designed for between-row crop culti-
vation. Instead of stirring the soil, it
slices through just below the surface to
eliminate practically any weeds in its path.
The Sweep mounts easily to the optional
Tow Hitch Attachment at the rear of the
PTO Power Unit. The blade is made of
high carbon, heat treated steel and
measures 2" wide (overall wing span is
20").
The unique way the Sweep works,
skimming along just underneath the soil’s
surface without turning the soil over,
makes this the ideal tool for use in dry,
dusty conditions where it is important to
keep soil disturbance to a minimum.
And, because of its 20" wide cutting path,
it does an effective cultivation job at a fast
speed.
The Sweep’s natural shallow cultivation
helps to prevent weed seeds from being
brought to the soil’s surface. This
shallow cultivation feature also means
there’s less chance of damaging the roots
of your vegetables. For deeper or more
shallow cultivating, the blade depth can
be changed with a simple adjustment..
Wheel Weights
290-266-081
Help increase traction by putting extra
weight directly on the wheels. They
reduce bucking and jumping when deep-
tilling in heavy soil. They’re shipped
empty– fill them with material like
concrete, sand, gravel, etc. They bolt
directly to the tiller wheels.
Wrap-Around Bumper Guard
290-255-081
Order this Bumper Guard by itself or
receive it as one of the components if you
order the combination Dozer/ Snow Blade
attachment. Protects the engine from
damage by wrapping around and protect-
ing many of the engine components. 1"
diameter, high-strength steel tubing.
Hiller/Furrower Attachment
290-250-081
The most popular attachment because it
does so many jobs. Mounts to the rear of
the depth regulator bracket. Furrower
blade easily makes plant rows, trenches,
ditches to 8" deep. When hiller wings are
attached to furrower blade, attachment
makes hilled rows and raised bed
gardens. Converts from a furrower to a
hiller and back again, in seconds, without
tools.
