CONTROLS
Steering Control Levers
WARNING! The machine can turn very rapidly if one
steering control is moved much further forward than the
other.
Park Brake
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.
The park brake is integrated with the steering control levers.
Move the levers outward from the neutral position to engage
the park brake.
To release the park brake, rotate both steering control levers
inwards to the neutral position. Do not attempt to operate the
unit without both levers being inwards out of the engaged
position or machine components could be damaged.
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.
IMPORTANT INFORMATION The machine must stand
absolutely still when applying the park brake. Always set
the park brake before dismounting. Release the park brake
before moving the mower.
If the steering controls are in uneven positions when standing
still or do not fit in the slots for moving the controls outward,
they can be adjusted.

CONTROLS
Throttle Control
Service Meter
The throttle control regulates the engine speed and the rate of
rotation of the blades, assuming the blade switch is pulled out.
See Blade Switch.
The service meter displays the total number of hours the
engine has run and indicates when the engine and mower
need servicing.
To increase or decrease the engine speed, the control is
moved forward or back respectively.
Avoid idling the engine for long periods, as there is a risk
of fouling the spark plugs. USE FULL THROTTLE WHEN
MOWING, for best mower performance and battery charging.
After every 50 hours of operation, an oil can icon will appear
and stay on for two hours, before an automatic reset occurs.
To manually reset the meter, turn the key off and on five times
at one second intervals. To service the engine and mower, see
the Service Journal of this manual.
Note: The service meter operates (clocks hours) only when the
engine is running. Be sure to turn the key off when the unit is
not in use, to prevent meter hours from accumulating.
Cold Weather Control
In temperatures below 32OF, move the throttle control forward
past the start detent to the snowflake symbol. Once the engine
has started, slowly move the throttle control back to the full
throttle position.
Blade Switch
To engage the mower deck, pull the knob out; mower blades
are disengaged when the knob is pressed down.

CONTROLS
Fuel Tank
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 for
additional information. Never use engine or carburetor
cleaners in the fuel tank or permanent damage may occur.
Tracking
WARNING! Gasoline is highly flammable.
Observe caution and fill the tank outdoors (see the safety
instruction).
WARNING! The engine and the exhaust system,
become very hot during operation. There is a risk for burns
if touched. Allow engine and exhaust system to cool 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.
If the mower is not tracking straight, check the air pressure in
both rear tires. Recommended air pressure for the rear tires is
15 psi (1 bar).
1. Tracking adjustments are made using the tracking bolts.
The tracking bolts act as limiting devices for the motion
control levers when in the full-forward position.
2. For preliminary tracking adjustment, move unit to an open,
unobstructed area such as an empty parking lot or open
field.
Read the safety instructions before refueling. The machine has
one fuel tank, just behind the console. The tank capacity is 3½
gallons (13.25 litres).
Regularly check the gas cap gasket for damage and keep the
cap properly tightened.
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. Do not use E85
alcohol based fuel. Damage to engine and components may
occur.

OPERATION
Read the Safety section and following pages, if you are
unfamiliar with the machine.
Before Starting
1. Read the sections on Safety and Controls before starting
the machine.
Training
2. Perform the daily maintenance before starting (see
Due to unique steering capabilities, zero turn mowers are far
more maneuverable than typical riding mowers.
Maintenance Schedule in the Maintenance section).
3. Check that there is sufficient fuel in the fuel tank.
4. Adjust the seat to the desired position.
The following conditions must be fulfilled before the engine
can be started:
• The blade switch must be pressed down into the
disengaged position.
This section should be reviewed in its entirety prior to
attempting to move the mower under its own power. When
first operating the mower or until becoming comfortable with
controls, use a reduced throttle speed and reduced ground
speed. DO NOT move control levers to the furthest forward or
reverse positions during initial operation.
First time users should become familiar with the mower’s
movement on a hard surface, such as concrete or blacktop
PRIOR to attempting to operate on turf. Until the operator
becomes comfortable with the mower controls and zero turning
capability, overly aggressive maneuvers may damage turf.
• Both steering / park brake controls must be in the locked
(outer) position.
WARNING! Engine exhaust and certain vehicle
components contain or emit chemicals considered to cause
cancer, birth defects or other reproductive system damage.
The engine exhaust contains carbon monoxide, which is a
odorless, colorless, poisonous gas. Do not use the machine
in enclosed spaces.
Steering
To move forward and backward
The direction and speed of the mower’s movements are
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.
Starting the Engine
First time users should push the mower (see Moving the
Machine By Hand in the Operation section) to an open, flat
area without other people, vehicles or obstacles nearby. To
move the unit under its own power, the operator must sit in the
seat and start the engine (see Before Starting in the Operation
section). Adjust the engine speed to idle and disengage the
park brake by moving the steering control levers inward. Do
not engage the blades. As long as the control levers have not
been moved forward or backwards, the mower will not move.
1. Sit on the seat.
2. Raise the mower deck to the highest position.
Slowly move both control levers slightly forward. This will allow
the mower to move forward in a straight line. Pull the control
levers back to the neutral position and the mower should stop
moving.
Pull back slightly on control levers, allowing the mower to
move backwards. Push the control levers forward 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.
3. Disengage the mower blades by pressing the blade
switch downwards.
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, complete the turn.

6. Press in and turn the ignition key to the start position.
position.
7. When the engine starts, immediately release the ignition
key back to the run position.
5. Move the throttle lever to the full throttle position.
NOTE: There is a detent at the full throttle position to aid in
setting the control.
IMPORTANT INFORMATION Do not run the starter for
more than 5 seconds each time. If the engine does not
start, wait approximately 10 seconds before retrying.
8. Set the engine speed with the throttle. Allow the engine to
run at a moderate speed, approximately mid throttle, for a
short time before use.
9. USE FULL THROTTLE WHEN MOWING.
Running
1. Release the park brake by pulling the steering / park
brake controls inwards to the neutral position.
NOTE: The mower is equipped with an operator presence
system. When the engine is running, any attempt by the
operator to leave the seat without first setting the park
brake will shut off the engine.
If the temperature is below 32OF, move the throttle lever
up to the cold weather (snowflake) starting position.
2. Lower the mower deck to the desired cutting height.
When the engine has started, move the throttle lever back
to full throttle detent and allow the engine to warm up for a
short period before operating the unit. Failure to move the
throttle from the cold weather starting position will result in
poor engine performance, smoke and spark plug fouling.
WARNING! Make sure that no one is near mower
when engaging blade switch.
Make sure the work area is free from objects that could be
thrown by the rotating blades.

OPERATION
3. Move throttle control to full throttle (rabbit symbol).
• 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.
4. Engage the mower deck by pulling the blade switch up.
5. Rotate control levers inward and slowly move both control
levers slightly forward to move forward in a straight line.
• When mowing large areas, start by turning to the right so
that clippings will discharge away from shrubs, fences,
driveways, etc. After one or two rounds, mow in the
opposite direction making left hand turns until finished.
Stopping the Engine
1. Move the throttle to the minimum position (tortoise
symbol).
2. Move the steering / park brake controls outward from the
neutral position.
3. Disengage the mower deck by pressing the blade switch
down.
• Avoid mowing wet lawns. The mowing result is poorer
because the wheels sink into the soft lawn, clumps build,
and 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 flooding water on top surface, engine and electrical
components.
4. Raise the mower deck to the highest position.
If the engine has been worked hard, allow it to idle at
least 60 seconds to attain a normal operating temperature
before stopping. To prevent fouling the spark plugs, avoid
idling the engine for longer periods.
5. Turn the ignition key to the stop position. Remove key.
Always remove key when leaving the mower to prevent
unauthorized use.
• When the mulching kit is used, it is important that the
mowing interval is frequent.
IMPORTANT INFORMATION Leaving the ignition switch
in any other position than OFF will cause the battery to be
discharged.
Operating On Hills
Read the Safety Instructions Driving on Slopes in the Safety
section.
• The slowest speed possible should be used before starting
up or down hills.
• Avoid stopping or changing speed on hills.
• If stopping is absolutely necessary, pull steering controls
into the neutral position and the push to the outside of the
unit to engage the park brake.
• To restart movement, move the steering controls back to the
neutral position.
Mowing Tips
• Observe and flag rocks and other fixed 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" during the cool season and over 3" during the
hot months. For healthier and better looking lawns, mow
often after moderate growth. For best cutting performance,
grass over 6" in height should be mowed twice. Make the
first cut relatively high, the second to the desired height.
• Press forward to regain forward motion.
• Make all turns slowly.
• The mowing result will be best with a high engine speed
(blades rotate rapidly) and low speed (rider moves slowly).
If the grass is not too long and dense, the driving speed
can be increased without negatively affecting the mowing
result.
WARNING! Do not drive up or down hills with slopes
greater than 10 degrees. Do not drive across slopes.
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.

MAINTENANCE
Safety System
Park Brake
The machine is equipped with a safety system that prevents
starting or driving under the following conditions.
The engine can only be started when:
• the mower deck is disengaged.
• the steering / park brake controls are in the outer, locked
neutral position.
Visually check that no damage is found on the steering control
levers, links or switches belonging to the park brake. Perform a
standstill test and check that there is sufficient braking action.
To adjust the park brake, contact the Husqvarna service
workshop.
IMPORTANT INFORMATION The machine must be
absolutely standing still when applying the park brake.
WARNING! Faulty adjustment will result in reduced
braking ability and can cause an accident.
Tire Pressures
All tires should be at 15 psi / 103 kPa / 1 bar.
Make daily inspections to ensure that the safety system works
by attempting to start the engine when one of the conditions is
not met. Change the conditions and try again.
If the machine starts when one of these conditions is not met,
turn the machine off and repair the safety system before using
the machine again.
Make sure the engine stops when the park brake is not
engaged and the operator leaves the seated position.
Check that the engine stops if the mower blades are engaged
and the driver temporarily moves off the drivers seat.
IMPORTANT INFORMATION DO NOT add any type of
tire liner or foam fill material to the tires. Excessive loads
created by foam filled tires will cause premature failures.
IMPORTANT INFORMATION To be able to drive, the
driver must sit in the seat and the steering / park brake
controls must be moved into the engaged (outer) position.
Otherwise the engine will stop.
Only use O.E.M. specified tires.

Check every 200 hours. Check that wheels rotate freely. If
wheels do not rotate freely take the unit to your dealer for
service.
Check every 100 hours of operation. Check for severe
cracking and large nicks.
NOTE: The belt will show some small cracks in normal
operation.
Foam filled tires or solid tires will void the warranty.
The belts are not adjustable. Replace belts if they begin to slip
from wear.
Deck Belt Removal
Removal and installation
Remove nut and caster bolt. Pull the wheel out of the yoke and
take care of the spacers. Install in reverse order. Tighten caster
bolt.
1. Park on a level surface. Apply parking brake.
2. Lower the deck into the lowest cutting position.
3. Remove bolts from belt shields and remove shields.
4. Remove any dirt or grass that may have accumulated
around the cutter housings and entire deck surface.
5. Remove tension on the belt by moving the idler arm.
6. Carefully slip belt up over the top of the cutter housing
pulleys and remove belt. Rolling belt over the pulleys may
damage the belt.
Deck Belt Installation
NOTE: For ease in installing the deck belt, refer to the
routing decal on the top of the deck.
1. Wrap the deck belt around the electric clutch pulley that is
located on the engine shaft.
2. Route the belt forward and up onto the deck.
3. Place belt around spring loaded idler pulley.
Anti-scalp Rollers
Anti-scalp rollers are properly adjusted when they are just
slightly off of the ground when the deck is at the desired
cutting height in the operating position. Anti-scalp rollers then
keep the deck in the proper position to help prevent scalping
in most terrain conditions.
The anti-scalp rollers can be set in three positions:
• Upper position 1½" to 2½" (38 to 64 mm) grass
• Middle position 2½" to 4" (64 to 102 mm) grass
• Lower position 4" to 6" (102 to 128) mm grass.
The rollers should be approximately ¼" (6.5 mm) from the
ground.
4. Wrap the belt around the stationary idler pulley and
around the mandrel housings.
5. Push inward on the idler arm and carefully route belt over
stationary idler pulley. Once belt is properly routed, slowly
release idler arm to tension belt.
6. Double check belt routing to make sure it matches the
routing decal, and the belt does not have any twist.
Correct as needed.
7. Replace belt shields on both mandrel housings and
secure with fasteners.
IMPORTANT INFORMATION Adjust anti-scalp rollers with
the mower on a flat level surface.
To avoid deck damage, the anti-scalp rollers must not be
adjusted to support the deck.

4. Turn any blade to align with the deck front-to-rear. If the
Adjusting the Mower Deck
front blade tip does not measure 1/8" to ½" higher in the
rear—with a 5/8 or adjustable wrench, turn the nuts on the
front suspension linkage. Clockwise raises the front of the
mower, counter clockwise will lower the front. Adjust nuts
until rear of mower deck is positioned level to 1/8" higher in
the rear than the side-to-side measurement.
Leveling deck
Adjust the deck while the mower is on a level surface.
Make sure the tires are inflated to the correct pressure. See
Technical Data / Transmission. If tires are under or over
inflated, the deck cannot be properly adjusted. Raise the deck
to the highest (transport) position.
The deck should be adjusted slightly higher in the rear.
NOTE: To insure accuracy of leveling procedure, mower deck
drive belt must be installed prior to leveling deck.
1. Wear heavy gloves. Turn each outer blade tip to align front
to rear with the deck side-to-side.
NOTE: For illustration, the front foot rest has been
removed. The adjustment can be made without removal.
2. Measure from the floor surface up to the bottom of the
blade tip on the discharge side of the mower deck.
Record the measurement.
3. Move to the opposite side, check that measurement is the
same. If adjustment is required—with a ¾" or adjustable
wrench, turn the lift link adjustment nuts on either side
counter clockwise to lower or clockwise to raise. Adjust
until both measurements are equal.
NOTE: This will place the mower deck in a standard
measurement position. Depending on the type of grass
being mowed or environmental conditions, additional
adjustments may be required to achieve the desired cut.

MAINTENANCE
Cutting Blades
Cleaning
For the best mowing results, it is important that blades are well
sharpened and not damaged.
Replace blades that have been bent or cracked when hitting
obstacles.
Regular cleaning, especially under the mower deck, will
increase the machine’s life-span. Make it a habit to clean the
machine directly after use (after it is cooled), before the debris
sticks.
Do not spray water on the top of the mower deck. Use
compressed air to clean the top side of mower deck. Regularly
clean the underside of the deck with normal water pressure.
Do not use a high pressure washer or steam cleaner. Avoid
spraying engine and electrical components with water.
Let the service workshop decide whether a blade with large
nicks can be repaired/ground or must be replaced. Balance
the blades after sharpening.
Check the blade mounts.
For models fitted with a cleanout port, attach the quick connect
(from the accessory packet) to any garden hose. After mowing,
snap the hose to the cleanout port and turn on water supply.
CAUTION! Blades are sharp. Protect your hands
with gloves and/or wrap blades with a heavy cloth
when handling.
The sharpening of blades should be carried out by
an authorized service workshop.
Blade replacement
1. Remove blade bolt by turning counter clockwise.
2. Install new or resharpened blade with stamped GRASS
SIDE facing towards ground/grass (down) or THIS SIDE
UP facing deck and cutter housing.
3. Seat the blade's opening firmly onto the cutter housing.
4. Tighten blade bolt securely.
5. Torque blade bolt to 45-60 ft/lbs (60-81 Nm).
Restart the mower and engage the blades to use the spinning
action to wash away debris. Make sure the hose is away from
the mower blades.
Do not rinse hot surfaces with cold water. Let unit cool before
washing.
CAUTION! Use protective glasses when cleaning
and washing.
Hardware
IMPORTANT INFORMATION Special blade bolt is heat
treated. Replace with a Husqvarna bolt if required. Do not
use lower grade hardware than specified.
Check daily. Inspect the entire machine for loose or missing
hardware.

Filter change
Oil change
Level check
1/365 Every day
General
Remove the ignition key to prevent unintentional movements
during lubrication.
When lubricating with an oil can, it must be filled with engine
oil.
When lubricating with grease, unless otherwise stated, use a
high grade molybdenum disulphide grease.
For daily use, the machine should be lubricated twice weekly.
Wipe away excess grease after lubrication.
Deck Spindles
Lower the cutting deck completely. Lubricate with a grease
gun, 2-3 strokes per spindle through the openings in the belt
shields.
If a grease gun without rubber hose is used, the foot plate
must be removed to access the center spindle.
It is important to avoid getting lubricant on the belts or
the drive surfaces of the belt pulleys. Should this happen,
attempt to clean them with spirits. If the belt continues to slip
after cleaning, the belt must be replaced. Gasoline or other
petroleum products must not be used to clean belts.
IMPORTANT INFORMATION Use minimal lubrication
and remove excess lubricant so that is does not come into
contact with belts or belt pulley drive surfaces.
Transmission
The transmission is maintenance free with no need for level
checks or oil changes. If a leak occurs, replace the unit or
contact your Husqvarna dealer.

STORAGE
To ready the machine for storage:
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.
The machine should be readied for storage at the end of the
mowing season or if it will not be in use for more 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 to prevent 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 ten minutes after
adding the stabilizer so that it reaches the carburetor. Do not
empty the fuel tank and the carburetor if stabilizer has been
added.
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.
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 dryer, 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 store far
away from open flame or sources of ignition. Never use
gasoline for cleaning. Use a degreaser and warm water.
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.
