SAFETY
Slope Operation
Slopes are a major factor related to loss of control and
tip-over accidents, which can result in severe injury or
death. Operation on all slopes requires extra caution. If
you cannot back up the slope or if you feel uneasy on
it, do not mow it.
Mow up and down slopes (10 degrees maximum), •
not across.
Watch for holes, ruts, bumps, rocks, or other •
hidden objects. Uneven terrain could overturn the
machine. Tall grass can hide obstacles.
Choose a low ground speed so that you will not •
have to stop while on the slope.
Do not mow on wet grass. Tires may lose traction.•
Avoid starting, stopping, or turning on a slope. If •
the tires lose traction, disengage the blades and
proceed slowly straight down the slope.
Keep movement on the slopes slow and gradual. •
Do not make sudden changes in speed or
direction, which could cause machine to roll over.
Use extra care while operating machine with grass •
catchers or other attachments; they can affect the
stability of the machine.

CONTROLS
Steering 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.
In order, 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.
If the steering controls are in uneven positions when
standing still or do not t in the slots for moving the
controls outward, they can be adjusted.

OPERATION
Read “Safety Instructions” section and 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 rst 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 rst 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 effected 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.
First time users should push mower (see “Moving by
Hand” in the Operation section) to an open, at area,
without other people or vehicles/obstacles nearby. In
order to move unit under its own power, the operator
must be in the seat, start engine (see “Before Starting”
in Operation section), adjust engine speed to idle,
disengage parking brake, do not engage blades at
this time, rotate control levers inward. As long as
the control levers have not been moved forward or
backwards, 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 neutral 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.
IMPORTANT INFORMATION
When control levers are in the reverse position
they return to neutral when released. This may
cause the mower to suddenly stop.
To turn to the right
While moving in a forward direction, pull the right lever
back towards the neutral position while maintaining the
position of the left lever, this will slow 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, rst pull both
control 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.

OPERATION
Mowing Tips
Observe and ag rocks and other xed objects to •
avoid collisions.
Begin with a high cutting height and reduce it until •
the desired mowing result is attained.
The average lawn should be cut to
2½" (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
rst 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.
The nest 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 without poor
mowing results.
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.
Use compressed air to clean top surface of the •
deck. Avoid ooding water on top surface, engine
and electrical components.
When the mulching kit is used, it is important that •
the mowing interval is frequent.
WARNING!
Clear the lawn of stones and other
objects that can be thrown out by the
blades.
8011-603
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.

control lever out of the lock notch and down into
the lower position.
Raise the mower deck by pulling the lifting lever •
upward to the transport position.
When the machine is standing still, activate the •
parking brake by pulling the lever backward.
Move the throttle to the minimum position (tortoise •

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 specied by
the manufacturer of the stabilizer. Run the engine for
at least 10 minutes after adding the stabilizer so that it
reaches the carburetor. Do not empty the fuel tank and
the carburetor if you have added stabilizer
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 ames, sparks, or a
pilot light such as in a boiler, hot water
tank, clothes drier, etc. Handle the fuel
with care. It is very ammable and
can cause serious personal injury and
property damage. Drain the fuel into
an approved container outdoors and
far away from open ame. Never use
gasoline for cleaning. Use a degreaser
and warm water instead.
To ready the machine for storage, follow these steps:
Thoroughly clean the machine, especially under 1.
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.
Inspect the machine for worn or damaged parts 2.
and tighten any nuts or screws that may have
become loose.
Change the engine oil; dispose of properly.3.
Empty the fuel tanks or add a fuel stabilizer. Start 4.
the engine and allow it to run until the carburetor
is drained of fuel or the stabilizer has reached the
carburetor.
Remove the spark plug and pour about a 5.
tablespoon of engine oil into the cylinder. Turn
over the engine so that the oil is evenly distributed
and then ret the spark plug.
Lubricate all grease zerks, joints, and axles.6.
Remove the battery. Clean, charge, and store the 7.
battery in a cool place, but protect it from direct
cold.
Store the machine in a clean, dry place and cover 8.
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 annual checkup at an authorized service workshop
is a good way to ensure that the machine performs its
best the following season.
