OPERATION
OPERATION
The 3 Point Hitch Wood Chippers are designed to chip or
chop scrap lumber, small trees, brush, limbs and other
wood debris. The chipped material is fine enough to be
composted or used in a variety of ways.
It is the responsibility of the owner or operator to read
this manual and to train all other operators before they
start working with the machine. Follow all safety instruc-
tions exactly. Safety is everyone's business.
By following recommended procedures, a safe working
environment is provided for the operator, bystanders, and
the area around the worksite. Untrained operators are not
qualified to use the machine.
The Tractor Mounted Wood Chipper is a rotor with blades
for chipping wood. A hinged feed hopper moves the wood
material into the rotor. Each rotor is designed with 4
blades and a twig-breaker to generate the small pieces of
wood.A stationary knife at the rear of the rotor housing is
placed by the moving knives to shear, chip or chop the
material. The tractor provides rotational power through
its hydraulic system into the hydraulic motor on the rotor
shaft. This drive system is contained in the front frame.
Although there are no operational restrictions on the
Wood Chipper when used for the first time, it is recom-
mended that the following mechanical items be checked:
After operating for 1 hour:
1. Torque all fasteners and hardware.
2. Check condition of rotor bearings.
3. Check the condition and clearance of the twig-breaker,
rotor and stationary blades. Adjust or replace as required.
4. Check for entangled material. Remove all entangled
material before resuming work.
5. Lubricate all grease fittings.
After operating for 10 hours:
1. Repeat steps 1 through 5 listed above. (After operating
for 1 hour)
2. Go to the normal servicing and maintenance schedule
as defined in the Maintenance Section.
Efficient and safe operation of the Tractor Mounted Wood
Chipper requires that each operator reads and under-
stands the using procedures and all related safety
precautions outlined in this section. A pre-operation
checklist is provided for the operator. It is important for
both the personal safety and maintaining good mechani-
cal condition that this checklist is followed. Before
operating the Wood Chipper and each time thereafter, the
following areas should be checked off:
1. Lubricate the machine per the schedule outline in the
Maintenance Section.
2. Check the rotor, blades, and twig-breaker. Remove any
twine, wire or other material that has become entangled.
3. Check the condition and clearance of the twig- breaker,
rotor, and stationary blades. Adjust or replace as required.
4. Check that all bearings turn freely. Replace any that are
rough or seized.
5. Make sure that all guards and shields are in place,
secured and functioning as designed.
6. Check the condition of the curtain in the feed hopper. It
must be in good condition to prevent chips from flying out.

OPERATION
Follow this procedure to prepare and setup the machine
at the work site:
1. Use the Tractor to position the Wood Chipper at the
work site.
IMPORTANT
Position the machine so the prevailing wind/breeze
blows the exhaust gases/fumes away from the opera-
tor's station.
2. Lower the feed hopper down into its working configura-
tion:
a. remove the nuts on the hopper anchor bolts,
b. unpin and the feeder hopper latch
c. carefully lower the hopper and secure it with the with
the nuts on the anchor bolts. d. Secure the feed hopper
latch to the discharge chute with the latch pin
A PTO drive line is supplied with the machine. To accom-
pany the variety of 3 point hitch geometry available
today, the drive line can be too long for most machines or
too short for others. It is very important that the drive
line be free to telescope but not to bottom out when
going through its working range. If the drive line bottoms
out, the bearings on both the machine and tractor PTO
shaft will be overloaded and fail in a short time.
1. To determine the proper length of the drive line, follow
this procedure:
a. Clear the area of bystanders, especially small children.
b. Attach the chipper to the tractor but do not attach the
drive line.
c. Raise the machine until the input shaft is level with
the tractor PTO shaft.
d. Measure the dimension between the locking grooves
on the tractor PTO shaft and the machine input shaft.
e. Measure the same dimensions on the compressed
drive line.
f. If the compressed drive line dimension exceeds the
machine dimension, the drive line will have to be cut.

2. When cutting the drive line, follow this procedure:
a. Subtract the machine dimension (A) from the uncut
drive line dimension (B) or (B-A). This dimension deter-
mines how much too long the drive line is.
b. Add another inch (25 mm) to the dimension to be sure
it doesn't bottom out, to determine (C) the cut off dimen-
sion.
c. Use a hacksaw to cut dimension (C) from both ends.
Cut both the plastic tubes and the metal cores.
d. Use a file to remove the burrs from the edges that
were cut.
e. Assemble the 2 ends of the shaft.
f. Make sure the shaft can telescope freely. If it does
not, separate the 2 parts and inspect for burrs or
cuttings on the shaft ends. Be sure it telescopes freely
before installing.
IMPORTANT It may be necessary to add weight to the
lower lift arms to bring them to the required height.
When attaching chipper to a tractor, follow this proce-
dure.
1. Clear the area of bystanders, especially small children.
2. Make sure there is enough room and clearance to
safely back up to the chipper.
3. Place the tractor arms in their full sway position.
4. Back up slowly and align the lower link arms to the
pins on the machine.
5. Mounting without a Quick Hitch
a. Align the left lower link with the left chipper pin.
b. Insert the left pin through the ball and install the
retainer.
c. Align the right arm to the pin by turning the jackscrew
on the arm.
d. Insert the right pin through the ball and install the
retainer. Return the jack- screw to its starting position.
e. Remove the top pin and install the top link. Use the
turnbuckle to align the top link. Insert the pins and install
the retainers. Return the turnbuckle to its original length
and lock.
6. Install the PTO drive line:
NOTE
Be sure the telescoping portion of the shaft is greased
and free of dirt.
a. Slide the collar back on the yoke, align the splines and
slide the yoke on the tractor.

doesn't bottom out.
8. Level the machine front and rear, and side to side
using the jackscrew on the right arm and the turnbuckle-
onthe top link.
9. The chipper should always be level on the ground in its
working position.
10. To unhook from the tractor, reverse the above proce-
dure. Always park the machine in a dry, level area. If
vandalism is a problem, remove the PTO drive line and
store in a secure place.
The Wood Chipper is a strong, rugged machine that is
built to a straightforward design which provides consis-
tent chipping of logs up to 6" (152mm)
Always wear personal protective equipment (PPE) when-
ever operating the machine. This includes but is not
limited to protective shoes with slip resistant soles,
protective goggles or face shield, heavy gloves, hearing
protection and protective clothing.
Do not place metal, bottles, cans, rocks, glass or other
solid material into the wood chipper. If something like
this gets into the machine, stop the machine immediate-
ly for a detailed inspection. Stop engine, remove ignition
key and place in your pocket and wait for all moving parts
to stop before inspecting or unplugging. Inspect machine
for damaged or loosened parts before resuming work.
Caution and care should be exercised when feeding
material into the feeder. Do not reach into the hopper
past the curtain barrier.
a. Before beginning to feed the rotor is up to speed.
b. Slowly slide the wooden material into the feed hopper
and move it into the rotor.
c. Do not force the material into the rotor, as the material
engages the rotor, the rotor will draw the material in. Use
continuous lite pressure to guide in the material.
d. Be aware of how much material you feed in, slow down
or stop if the rotor begins to slow down.
e. Do not reach into the feed hopper further than the
curtain to be sure not to contact the blades on the rotor.
f. Use a stick or branch to push any piece of material into
the rotor that does not move on its own. If the jam
persists then stop the engine and wait for the rotor to
stop and then clear the jam. Do not take a chance with
getting your hand caught in the rotor.
g. Ensure your wood chip pile is contained and doesn't
affect the immediate work area.
Although the machine is designed to handle a wide
variety of material without any problem, occasionally it
plugs. When the machine plugs, follow this procedure to
unplug:
a. Clear the area of bystanders, especially small children.
b. Turn off the hydraulics, stop the engine, remove the
ignition key and place it in your pocket and wait for all
moving parts to stop before unplugging.
c. Pull the material out of the feed hopper. Be sure all the
material is out, and nothing is jammed or wedged
between the input opening and the rotor.
d. Pull the material out of the discharge hood. Use a stick
to poke loose any material jammed into the discharge
hood. Do not allow anything to remain in this area.
e. Check that everyone is clear of machine before
restarting engine.
f. Start the engine turn on the hydraulics, and resume
working.
a. Clear the area of bystanders, especially small children.

MAINTENANCE
By following a careful service and maintenance program
for your machine, you will enjoy many years of trouble-free
operation.
The rotor and ledger blades need to be sharp for the
Chipper to perform as expected. Periodic inspection is
recommended. Keep the blades sharp to reduce the
amount of power required during operation. Watch the
sharpness of the blades when processing material with a
lot of sand, soil or dirt mixed with it. Reverse or sharpen
the blades if the cutting edge becomes dull. Twig breaker
should be inspected for gouges or bent.
The rotor is equipped with 4 blades spaced evenly to keep
the rotor in balance. If one needs to be changed, the one
opposite should also be changed.
It is recommended that the rotor blades be removed from
the rotor when sharpening. Always sharpen the blades at
a 45° angle to provide the best cutting effect as it meets
the stationary blade. Be sure to tighten the blade mount-
ing bolts to their specified torque when reinstalling the
blades to the rotor.
1. Turn off the hydraulics, stop the engine, remove the
ignition key, and place it in your pocket and wait for all
moving parts to stop.
2. Remove the bolt that secures the upper rotor housing,
and carefully open the rotor housing.
3. Manually rotate chipper rotor plate so that the blade is
fully exposed
4. Remove the bolts that hold the rotor blade to the rotor,
remove the blade.
5. Rotate the blade and reinstall or replace with new or
resharpened blade.
6. Ensure the blade is properly oriented, with the leading
edge out. The blade is designed to fit into the rotor one
way only. See diagram for proper installation.
7. Tighten down bolts as specified in the torque chart.
8. Repeat steps for remaining blades.

The bx62S is equipped with a ledger (stationary) blade
that acts as a shear for the moving rotor blades. The
ledger blade is designed with 4 usable corners. When the
corner facing the rotor blade rounds over, remove the
blade and reinstall with a different corner facing the rotor
blade. It is recommended that the clearance between the
rotor and stationary blades be set and maintained at
1/32 to 1/16 " (.76 - 1.52 mm) to obtain the best perfor-
mance.
1. Turn off the hydraulics, stop the engine, remove the
ignition key and place it in your pocket and wait for all
moving parts to stop.
2. Remove the 2 bolts that hold the ledger blade to the
ledger mount, remove the blade.
3. Rotate the blade and replace or replace with new or
re-sharpened blade.
4. Hand tighten the bolts and set the clearance
between the ledger and rotor blades at 1/32 - 1/16" .
5. Tighten down bolts as specified in the torque chart .
CHECKING BOLT TORQUE
The tables shown below give correct torque values for
various bolts and cap screws. Tighten all bolts to the
torques specified in chart unless otherwise noted. Check
tightness of bolts periodically, using bolt torque chart as
a guide. Replace hardware with the same strength bolt.
Torque figures indicated above are valid for non-greased
or non-oiled threads and heads unless otherwise speci-
fied. Therefore, do not grease or oil bolts or cap screws
unless otherwise specified in this manual. When using
locking elements, increase torque values by 5%.
