Personal protective equipment
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
maxium), 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 all movement on the slopes slow
and gradual. Do not make sudden
changes in speed or direction, which
could cause the machine to roll over.
6003-004
Mow up and down, not side-to-side
WARNING!
Do not drive up or down hills
with slopes greater than 10
degrees. And do not drive
across any slopes.

CONTROLS
1. Parking Brake
IMPORTANT INFORMATION
The machine must be absolutely standing
still when applying the parking brake.
The parking brake is found on the left of the
machine. Pull the lever backward to activate
the brake and forward to release it.
8011-711
Parking brake not activated
2. 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.
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.

The machine has one fuel tank, just behind
the seat. The tank volume is 5.4 gallons
(20.4 liters).
The engine will run on a minimum of 85octane unleaded gasoline (no oil mix).
Environmentally adapted alkylate gasoline
can be used beneficially. See also Technical
Data concerning ethanol fuel. Methanol fuel is
not allowed.
WARNING!
Gasoline is highly flammable.
Observe caution and fill the
tank outdoors
(see the safety rules).
8011-761
Fuel tank
IMPORTANT INFORMATION
WARNING!
The engine and the exhaust
system, become very hot during
operation.
Risk for burns if touched.
Allow engine and exhaust
system to cool at least two (2)
minutes before refueling
WARNING!
Fill to bottom of filler neck. Do
not overfill. Wipe off any
spilled oil or fuel. Do not store,
spill or use gasoline near an
open flame.
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.
When operating in temperatures below 32° F.
(0° C.), use fresh, clean winter grade gasoline
to help insure good cold weather starting.

OPERATION
Operation
Read "Safety Instructions" section and following pages, if you are unfamiliar with the machine.
Training
Zero turn mowers are far more manueverable than typical riding mowers due to their unique steering
capabilities.
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 ZeroTurn
mowers to become familiar with the mowers 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 over aggressive maneuvers.
To move forward and backward
The direction and speed of the mowers 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.
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, flat area,
without other people or vehicles/obstacles near by. 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 park 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.
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, first 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.

Mowing Tips
•
Observe and flag rocks and other fixed
objects to avoid collisions.
WARNING!
•
Begin with a high cutting height and
reduce it until the desired mowing result
is attained.
Clear the area of objects such
as rocks, toys, wire, etc.,
which could be picked up and
thrown by the blades.
The average lawn should be cut to 2 1/2"
(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.
•
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 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 should 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 flooding water on top
surface of deck engine or electrical
components.
•
When the mulching kit is used, it is
important that the mowing interval is
frequent.

Purging Procedures
Due to the effects air has on efficiency in
hydrostatic drive applications, it is critical that
it is purged from the system.
These purge procedures should be
implemented any time a hydrostatic system
has been opened to facilitate maintenance or
any additional oil has been added to the
system.
The resulting symptoms in hydrostatic
systems may be:
1.
Noisy operation.
2.
Lack of power or drive after short term
operation.
3.
High operation temperature and
excessive expansion of oil.
Before starting, make sure the transaxle is at
the proper oil level. If it is not, fill to the
specifications outlined earlier.
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

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 oil 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
transaxle operates at normal noise levels
and moves smoothly forward and
reverse at tnormal speeds, then the
transaxle is considered purged.
5.
After the vehicle has been used two
times, the oil level should be checked
while the oil is cold and adjusted
accordingly.

STORAGE
Storage
To ready the machine for storage, follow these
steps:
Winter Storage
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 refit 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.
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 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 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 careless
use 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
instead.
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.
