CONTROLS
Motion Control Levers
The machine's speed and direction are continuously
variable using the two steering controls The steering
controls can be moved forward or backward about
a neutral position Furthermore, there is a neutral
position, which is locked if the steering controls are
moved outward
When both controls are in the neutral position (N), the
machine stands still
By moving both controls an equal amount forward
or backward, the machine moves in a straight line
forward or backward respectively
For example, to turn right while moving forward, move
the right control towards the neutral position The
rotation of the right wheel is reduced and the machine
turns to the right
Zero turn can be achieved by moving one control
backward (behind the neutral position) and carefully
moving the other steering control forward from its
neutral position, The rotation direction when zero
turning is determined by which steering control is
moved backward behind the neutral position. If the left
steering control is pulled backward, the machine turns
to the left Use extra care when using this maneuver
Steering controls

IMPORTANT INFORMATION
Experience indicates that alcohol blended
fuels (called gasohol, ethanol or methanol)
can attract moisture which leads to separation
and formation of acids during storage. Acidic
gas can damage the fuel system of an engine
while in storage. To avoid engine problems,
the fuel system should be emptied before
storage of 30 days or longer. Drain the gas
tank, start the engine and let it run until the
fuel lines and carburetor are empty. Use fresh
fuel the next season. See Storage Instructions
for additional information. Never use engine
or carburetor cleaners in the fuel tank or
permanent damage may occur.

OPERATION
Read the Safety Instructions section and the
following pages if you are unfamiliar with the machine
Training
Zero turn mowers are far more maneuverable than
typical riding mowers due to their unique steering
capabilities
We suggest that this section be reviewed in its entirety
prior to attempting to move the mower under its own
power Additionally, we suggest when first operating
the mower, use a reduced throttle speed and reduced
ground speed by NOT moving control levers to the
furthest forward or reverse positions during initial
operation, or until operator becomes comfortable
with controls We also suggest first time users, or new
users to Zero Turn mowers to become familiar with
the mower's movement on a hard surface, such as
concrete or blacktop PRIOR to attempting to operate
on turf Until operator becomes comfortable with
mower controls and zero turning capability, they may
damage turf due to overly aggressive maneuvers
Steering
To move forward and backward
The direction and speed of the mower's movements
is eflected by the movement of the control lever(s)
on each side of mower The left control lever controls
the left wheel The right control lever controls the right
wheel
moved forward or backwards, the mower will not
move, Slowly move both control levers forward slightly,
This will allow mower to start moving forward in a
straight line Pull back on control levers to the neulral
position and mower should stop moving Pull back
slightly on control levers, this will allow mower to start
moving backwards Push forward on control levers to
the neutral position and mower should stop moving,,
To turn to the right
While moving in a forward direction, pull the right lever
back towards the neutra! position while maintaining
the position of the left lever, this will stow the rotation
of the right wheel and cause the machine to turn in
that direction
To turn to the left
While moving in a forward direction pull the left lever
back towards the neutral position while maintaining
the position of the right lever, this will slow the rotation
of the left wheel and cause the machine to turn in that
direction..
To zero turn
While moving in a forward direction, first pull both
contro! levers back until the mower stops or slows
dramatically
Then by alternating one lever slightly to the forward
position and the other in the reverse position, the
mower turns to the direction of the reverse position
lever,
IMPORTANT INFORMATION
When control levers are in the reverse position
they return to neutral when released. This may
cause the mower to suddenly stop.
First time users should push mower (see Manual
Transport in the Operation section) to an open, flat
area, without other people or vehicles or obstacles

Mowing Tips
o Observe and flag rocks and other fixed objects to
avoid collisions
o Begin with a high cutting height and reduce it
until the desired mowing result is attained, The
average lawn should be cut to 2t/2° (64 mm)
during the cool season and over 3' (76 mm)
during the hot months For healthier and better
looking lawns, mow often after moderate growth
• For best cutting performance, grass over 6" (15
cm) in height should be mowed twice,, Make the
first cut relatively high; the second to the desired
height.
. The mowing result will be best with a high engine
speed (the blades rotate rapidly) and low speed
(the rider moves slowly), If the grass is not
too long and dense, the driving speed can be
increased without negatively affecting the mowing
result.
o The finest lawns are obtained by mowing often
The lawn becomes more even and the grass
clippings more evenly distributed over the mown
area The total time taken is not increased as a
higher operating speed can be used wilhout poor
mowing results.
o Avoid mowing wet lawns. The mowing result is
poorer because the wheels sink into the soft lawn,
clumps build, and the grass clippings fasten
under the cowling
- Hose the mower deck underside with water after
each use, When cleaning, the mower deck shall
be raised into the transport position Make sure
the mower is cooled and the engine is off,
o Use compressed air to clean top surface of the
deck, Avoid flooding water on top surface, engine
and electrical components
o When the mulching kit is used, it is important that
the mowing interval is frequent and that the deck
is cleaned more often,,
WARNING!
Clear the lawn of stones and other
objects that can be thrown out by the
blades.
Mowing pattern

WARNING!
Never drive the rider on terrain that
slopes more than 10 degrees. Mow
slopes up and down, never side
to side. Avoid sudden directional
changes.

weekly,
Wipe away excess grease after lubrication
It is important to avoid getting lubricant on the belts
or the drive surfaces on the belt pulleys Should this
happen, attempt to clean them with spirits, If the belt
continues to slip after cleaning, it must be replaced
Gasoline or other petroleum products must not be
used to clean belts,

Transaxle (Transmission) Fluid Change
This transaxle is designed with an external filter for
ease of maintenance To ensure constant fluid quality
levels and longer life, an oil filter change interval of
every 200 hours is recommended,
The following procedure is performed with the
transaxles installed in the mower and the mower on
levet ground Apply the pump release valve for each
transaxle and set the parking brake..
1 Remove the three t/¢ filter guard screws and filter
guard, Clean any loose debris from around the
perimeter of the filter See illustration
2, Place an oil drain pan (12" or more diameter and
8 qt capacity is optimal) beneath the oil filter.,
Remove the oil filter from the transaxfe
t0, Fill with 20W50 motor oil until oil just appears
at the bottom of each transaxles' top port
(approximately 2 quarts per transaxle, 4 quarts
total), Install the top port lug into each transaxle
as the oil level reaches the port
11 install and torque the top port plugs to I80 in Jibs
12 Continue to fill the transaxles through the
expansion tank until the "Full Cold" line is reached
(this will take approximately 23 additional ounces)
13, Reinstall the expansion tank cap by hand. Be
careful to not overtighten
t4_ Proceed to the purge procedure,
Drain old oil filters of all free-flowing oil prior
to disposal. Place used oil in appropriate
containers and dispose of it in accordance
with laws in your area.
3 After the oil has drained, wipe the filter base
surface and apply a film of new oi! to the gasket of
the replacement filter.
4 Install the new filter by hand, turning it three-
quarters to one full turn after the filter gasket
contacts the filter base surface
5, Reinstall the filter guard Torque screws to
65 inilbs, each°
6, Repeat steps on the opposite side
7. Drain old oil filters of atf free flowing oil prior to
disposal, Place used oil in appropriate containers
and dispose of it in accordance with laws in your
area,
8 Remove the top port plug (see illustration) from
the left side and right side of the transaxles prior
to filling with oil, This will allow the transaxles to
vent during oil fill
9, Remove the cap from the transaxles' expansion
tank located on the vehicle frame,

Purging Procedures
Due to the effects air has on efficiency in hydrostatic
drive applications, it is critical to purge the system..
These purge procedures should be impiemented
any time a hydrostatic system has been opened to
facilitate maintenance or any additional oil has been
added to the system
Resulting symptoms in hydrostatic systems may be:
_, Noisy operation.,
o Lack of power or drive after short term operation
o High operation temperature and excessive
expansion of oil
o Shortened component life.
Before starting, make sure the oil tank is at the proper
oil level tf not, fill to the specifications outlined above..
The following procedures are best performed with the
vehicle drive wheels off the ground, then repeated
under normal operating conditions.,
1 Disengage the brake if activated
2 With the bypass valve open and the engine
running at fast idle, slowly move the directional
control in both forward and reverse directions (5
or 6 times).. As air is purged from the unit, the oil
level will drop
3. With the bypass valve closed and the engine
running, slowly move the directional control
in both forward and reverse directions (5 to
6 times) Check the oil level and add oi! as
required after stopping the engine
4 It may be necessary to repeat Steps 2 and 3
until all the air is completely purged from the
system. When the hydraulic drive operates
at normal noise levels and moves smoothly
forward and reverse at normal speeds, the
hydraulic drive is considered purged.
5, After the vehicle has been used two times, the
oi! level should be checked while the oil is cold
and adjusted accordingly,

STORAGE
Winter Storage
At the end of the mowing season, the machine should
be readied for storage (or if it will not be in use for
longer than 30 days).,
Fuel allowed to stand for long periods of time (30 days
or more) can leave sticky residues that can plug the
carburetor and disrupt engine function
Fuel stabilizers are an acceptable option as regards
to the sticky residues that can occur during storage.
Add stabilizer to the fuel in the tank or in the storage
container. Always use the mixing ratios specified by
the manufacturer of the stabilizer. Run the engine for
at least t0 minutes after adding the stabilizer so that
it reaches the carburetor Do not empty the fuel tank
and the carburetor if a stabilizer has been added.
WARNING!
Never store an engine with fuel
in the tank indoors or in poorly
ventilated spaces where fuel vapor
can come in contact with open
flames, sparks, or a pilot light such
as in a boiler, hot water tank, clothes
drier, etc. Handle the fuel with care.
It is very flammable and can cause
serious personal injury and property
damage. Drain the fuel into an
approved container outdoors and
far away from open flame. Never
use gasoline for cleaning. Use
a degreaser and warm water.
To ready the machine for storage, follow these steps:
1 Thoroughly clean the machine, especially under
the mower deck.. Touch up damage to the paint
and spray a thin layer of oil on the underside of
the mower deck to avoid corrosion
2, Inspect the machine for worn or damaged parts
and tighten any nuts or screws that may have
become loose.
3.. Change the engine oil; dispose of properly
4. Empty the fuel tanks or add a fuel stabilizer, Start
the engine and allow it to run until the carburetor
is drained of fuel or the slabilizer has reached the
carburetor
5. Remove the spark plug and pour about a
tablespoon of engine oil into the cylinder. Turn
over the engine so that the oil is evenly distributed
and then refit the spark plug
6 Lubricate all grease zerks, joints, and axles
7. Remove the batlery Clean, charge, and store the
battery in a cool place, but protect it from direct
cold
8 Store the machine in a clean, dry place and cover
it for extra protection
Service
When ordering spare parts, please specify the
purchase year, model, type, and serial number
Always use genuine Husqvarna spare parts
An annuai check-up at an authorized service
workshop is a good way to ensure that the machine
performs its best the following season,
