INTRODUCTION  
Introduction  
Congratulations  
Thank you for purchasing a Husqvarna ride-on mower. This machine is built for the greatest efficiency and  
rapid mowing primarily of large areas. Controls in one place and a hydrostatic transmission regulated by

SAFETY INSTRUCTIONS  
Driving on Slopes  
Driving on slopes is one of the operations  
where the risk is greatest that the driver will  
lose control or the machine will tip over, which  
can result in serious injury or death. All  
slopes require extra caution. If you cannot  
reverse up a slope or if you feel unsure,  
do not mow the slope.  
Do as follows  
•
Remove obstacles such as stones,  
tree branches, etc.  
•
Watch out for and avoid driving over  
furrows, holes, and bumps. On uneven  
terrain, the machine can tip more easily.  
Long grass can hide obstacles.  
•
•
Mow up and down, not side-to-side.  
Drive evenly and slowly. Use small  
movements of the steering controls.  
•
•
Be extra cautious with any additional  
equipment, which can alter the  
machine’s stability.  
6003-004  
Mow up and down, not side-to-side  
If the machine stops while going uphill,  
disengage blades and back down slowly.  
Do not  
•
•
•
Do not make sudden changes in speed  
or direction.  
Do not drive the mower on terrain that  
slopes more than 10°.  
Do not mow near verges, ditches, or  
banks. The machine can suddenly spin  
around if a wheel goes over the edge of  
a drop or ditch, or if an edge gives way.  
•
Do not mow wet grass. It is slippery, and  
the tires can lose their grip, so that the  
machine slides.  
•
•
•
Do not try to stabilize the machine by  
putting a foot on the ground.  
8011-519  
Be extra cautious when driving on slopes  
Do not drive near verges or ditches  
when cleaning the machine.

and then, turn slowly and gradually  
downhill, if possible.  
•
Avoid starting or stopping on a slope. If  
the tires begin to slip, shut down the  
blades and drive slowly straight down the  
slope.

CONTROLS  
3. 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.  
8011-789  
Steering controls  
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.  
WARNING!  
The machine can turn very  
rapidly if one steering control  
is moved much further forward  
than the other.  
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

6. Refueling  
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 85-  
octane 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  
8011-761  
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!  
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.  
Instructions for additional information.  
Never use engine or carburetor cleaners  
in the fuel tank or permanent damage  
may occur.

OPERATION  
Operation  
Read “Safety Instructions” on page 7 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 recommend 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 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” on page 34) 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” on page 25), 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!  
Clear the lawn of stones and  
other objects that can be  
thrown out 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.  
When the mulching kit is used, it is  
important that the mowing interval is  
frequent.

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  
seated position.

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 plug 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.
