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.
8011-789
Steering controls
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.
Tracking
If the mower is not tracking straight, check the air
pressure in both rear tires. Recommended air pressure
is 15 psi. (1 bar) Tracking must be checked on a at
and level concrete or blacktop surface. If the unit
still does not track straight contact your Husqvarna
workshop for adjustments.
WARNING!
The machine can turn very

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.

Lifting Lever for the Mower Deck
The deck cutting height is achieved with the foot
pedal. To lift the deck, press the foot pedal forward.
To lower the deck, apply pressure to the top side
of the foot pedal and allow the pedal to pivot while
allowing the lift arm to rotate to the rear of the unit.
To stop at the desired cutting position, rotate the pedal
down into the notch in the height plate. The cutting
height range is from 1½" (38mm) to 5" (127mm) in
½" (13mm) increments. The heights are measured
from the ground up to the blade tip with the engine not
running.
IMPORTANT INFORMATION
In order to obtain an even cutting height it
is important that the air pressure in all four
tires is the same 15 psi (1 bar).

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 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.
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.
Steering
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.
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 “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.

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.

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:
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 stabilizer 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 ret the spark plug.
6. Lubricate all grease zerks, joints, and axles.
7. Remove the battery. 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 annual check-up at an authorized service workshop
is a good way to ensure that your machine performs its
best the following season.
