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.  
6003-004  
Mow up and down, not side-to-side  
Choose a low ground speed so that you  
will not have to stop while on the slope.  
WARNING!  
Do not mow on wet grass. Tires may lose  
traction.  
Do not drive up or down hills  
with slopes greater than 10  
degrees. And do not drive  
across any slopes.  
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.  
English-9

SAFETY INSTRUCTIONS  
Use extra care while operating machine  
with grass catchers or other attachments;  
they can affect the stability of the  
machine. Do not use on steep slopes.  
Do not try to stabilize the machine by  
putting your foot on the ground.  
Do not mow near drop-offs, ditches, or  
embankments. The machine could  
suddenly roll over if a wheel is over the  
edge or if the edge caves in.  
Children  
8011-519  
Tragic accidents can occur if the operator is  
not alert to the presence of children. Children  
are often attracted to the machine and the  
mowing activity. Never assume that children  
will remain where you last saw them.  
Be extra cautious when driving on slopes  
Never allow children to operate the machine  
Keep children away from the work area  
Keep children out of the mowing area  
and in the watchful care of a responsible  
adult other than the operator.  
Be alert and turn machine off if a child  
enters the area.  
Before and while backing, look behind  
and down for small children.  
Never carry children, even with the  
blades shut off. They may fall off and be  
seriously injured or interfere with safe  
machine operation. Children who have  
been given rides in the past may  
suddenly appear in the mowing area for  
another ride and be run over or backed  
over by the machine.  
8011-517  
Never allow children to operate the  
machine.  
Use extra care when approaching blind  
corners, shrubs, trees, or other objects  
that may block your view of a child.

1. 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.  
8011-751  
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.  
Motion control levers  
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.  
WARNING!  
The machine can turn very  
rapidly if one steering control  
is moved much further forward  
than the other.  
Tracking  
1
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 flat and level concrete or blacktop  
surface. If unit still does not track straight, contact a  
Husqvarna workshop for adjustment.

5. Refueling  
The machine has one fuel tank, just behind  
the seat. The tank capacity is 3 gallons  
(11.4 liters).  
The engine will run on a minimum of  
85-octane unleaded gasoline (no oil mix).  
Environmentally adapted alkylate gasoline  
can be used. See also Technical Data  
concerning ethanol fuel. Methanol fuel is not  
allowed.  
WARNING!  
Gasoline is highly flammable.  
Observe caution and fill the  
tank outdoors  
8011-752  
Fuel tank  
(see the safety rules).  
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  
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.  
Instructions for additional information.  
Never use engine or carburetor cleaners  
in the fuel tank or permanent damage  
may occur.  
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.  
When operating in temperatures below 32° F.  
(0° C.), use fresh, clean winter grade gasoline  
to help insure good cold weather starting.

12. Cutting height pedal  
The deck cutting height is obtained by  
pressing the foot pedal forward to lift the  
deck. To lower the deck, you apply pressure  
to the top side of the foot pedal and allow it to  
pivot while allowing the lift arm to rotate to the  
rear of the unit. To stop in a desired cutting  
position, rotate the foot pedal down into the  
notch in the height plate. The cutting height  
range is from 1 1/2" (38 mm) to 5" (127 mm)  
in 1/2" (13 mm) increments. The heights are  
measured from the ground up to the blade tip  
with the engine not running  
.
8011-753

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 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.  
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.

OPERATION  
Mowing Tips  
Observe and flag rocks and other fixed  
objects to avoid collisions.  
WARNING!  
Clear the area of objects such  
as rocks, toys, wire, etc.,  
which could be picked up and  
throw by the blades.  
Begin with a high cutting height and  
reduce it until the desired mowing result  
is attained.  
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.  
8011-603  
Mowing patterns  
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.  
WARNING!  
Never drive the rider on terrain  
that slopes more than 10°.  
Mow slopes up and down,  
never side-to-side. Avoid  
sudden directional changes.  
Use compressed air to clean top surface  
of the deck. Avoid flooding water on top  
surface, engine and electrical  
components.  
When the mulching kit is used, it is  
important that the mowing interval is  
frequent.

hard can damage the threads in the  
cylinder head.  
2. Remove the spark plug with a spark plug  
socket wrench.  
3. Check the spark plug. Replace the spark  
plug if fouled, the electrodes are burned  
and if the insulation is cracked or  
damaged. Clean the spark plug with a  
steel brush if it is to be reused.  
4. Measure the electrode gap with a  
gapping tool. The gap should be .030”  
(0.75 mm). Adjust as necessary by  
bending the side electrode.  
5. Reinsert the spark plug, turning by hand  
to avoid damaging the threads.  
6. After the spark plug is seated, tighten it  
using a spark plug wrench so that the  
washer is compressed. A used spark  
plug should be turned 1/8 of a turn from  
the seated position. A new spark plug  
should be turned 1/4 a turn from the

STORAGE  
To ready the machine for storage, follow these  
steps:  
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.  
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 foul the  
carburetor and disrupt engine function.  
2. Inspect the machine for worn or damaged  
parts and tighten any nuts or screws that may  
have become loose.  
Fuel stabilizers are an acceptable option as  
regards to the sticky residues that can occur  
during storage.  
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.  
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.  
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.  
WARNING!  
7. Remove the battery. Clean, charge, and store  
the battery in a cool place, but protect it from  
direct cold.  
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.  
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.
