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  
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.  
6003-004  
Mow up and down, not side to side  
Avoid starting, stopping, or turning on a  
slope. If tires lose traction, disengage blades  
and proceed slowly straight down the slope.  
WARNING!  
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.  
Do not drive up or down hills  
with slopes greater than 10  
degrees. And do not drive across  
any slopes.

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  
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.  
8011-509  
Be extra cautious when driving on slopes  
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.

WARNING!  
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 can turn very  
rapidly if one steering control  
is moved much further forward  
than the other.

OPERATION  
Read the “Safety Instructions” section and the  
following pages if you are unfamiliar with the machine.  
Steering  
To turn to the right  
Training  
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.  
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 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 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 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.  
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.  
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 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  
WARNING!  
Observe and flag rocks and other fixed  
objects to avoid collisions.  
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 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 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.  
8011-603a  
Mowing pattern  
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 degrees.  
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.

MAINTENANCE  
Ignition System  
The engine is equipped with an electronic ignition  
system. Only the spark plug requires maintenance.  
IMPORTANT INFORMATION  
Fitting the wrong spark plug type can  
damage the engine.  
For recommended spark plugs, see Technical Data.  
1. Remove the ignition cable boot and clean around  
the spark plug.  
Inadequately tightened spark plugs can  
cause overheating and damage the engine.  
Tightening the spark plugs too 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

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.  
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.  
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  
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.

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 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.  
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.
