CONTROLS
Steering 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.
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.

machine has one fuel tank, just behind the seat. The
tank capacity is 3.5 gallons (13.25 liters).
Regularly check the gas cap gasket for damage and
keep the cap properly tightened.
The engine will run on a minimum of 87-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.
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.
Risk for burns if touched.
Allow engine and exhaust system to
cool before refueling.

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 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 insure good
cold weather starting.

OPERATION
Read the Safety section and following pages, if you
are unfamiliar with the machine.
Training
Due to unique steering capabilities, zero turn mowers
are far more maneuverable than typical riding
mowers.
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.
IMPORTANT INFORMATION
When control levers are in the reverse position
they return to neutral when released. This may
cause the mower to suddenly stop.
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.
First time users should push the mower (see Manual
Transport 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, disengage the parking brake
but do not engage the blades at this time. Rotate
control levers inward. As long as the control levers
have not been moved forward or backwards, the
mower will not move.
Slowly move both control levers forward slightly. This
will allow mower to start moving 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.
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.

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" (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 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.
When the mulching kit is used, it is important that
the mowing interval is frequent.
WARNING!
Clear the lawn of stones and other
objects that can be thrown out by the
blades.
8011-603
Mowing pattern
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.

(2).
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.

4. Turn any blade to align with the deck in frontto-rear manner. If the 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, counterclockwise 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.
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
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. Antiscalp rollers then keep the deck in the proper position
to help prevent scalping in most terrain conditions.
IMPORTANT INFORMATION
Adjust anti-scalp rollers with the mower on a
flat level surface.
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
ground. Do not adjust the rollers to support the deck.
8050-830
Anti-scalp rollers
IMPORTANT INFORMATION
To avoid deck damage, the anti-scalp rollers
must not be adjusted to support the deck.
Caster Wheels
Check every 200 hours. Check that wheels rotate
freely. If wheels do not rotate freely take the unit to
your dealer for service.
Foam filled tires or solid tires will void the warranty.
1
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.
2
Only use O.E.M. specified tires.
Removal and installation
1. Remove nut and caster bolt.
2. Pull the wheel out of the yoke and retain the
spacer for reuse.
3. Install in reverse order.
4. Tighten caster bolt.
Hardware

MAINTENANCE
Cleaning
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.
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.
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.

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.
44
Wipe away excess grease after lubrication.
It is important to avoid getting lubricant on the belts
or the drive surfaces on the belt pulleys. Should this
happen, attempt to clean them with spirits. If the belt
continues to slip after cleaning, it must be replaced.
Gasoline or other petroleum products must not be
used to clean belts.
LUBRICATION

LUBRICATION
Transaxle (Transmission) Fluid Change
This transaxle is designed with an external filter for
ease of maintenance. To ensure constant fluid quality
levels and longer life, an oil filter change interval of
every 200 hours is recommended.
The following procedure is performed with the
transaxles installed in the mower and the mower on
level ground. Apply the pump release valve for each
transaxle and set the parking brake.
1. Remove the three ¼" filter guard screws and filter
guard. Clean any loose debris from around the
perimeter of the filter. See illustration.
2. Place an oil drain pan (12" or more diameter and
8 qt. capacity is optimal) beneath the oil filter.
Remove the oil filter from the transaxle.
3. After the oil has drained, wipe the filter base
surface and apply a film of new oil to the gasket of
the replacement filter.
4. Install the new filter by hand, turning it threequarters to one full turn after the filter gasket
contacts the filter base surface.
5. Reinstall the filter guard. Torque screws to
65 in/lbs. each.
6. Repeat steps on the opposite side.
7. Drain old oil filters of all free flowing oil prior to
disposal. Place used oil in appropriate containers
and dispose of it in accordance with laws in your
area.
8. Remove the top port plug (see illustration) from
the left side and right side of the transaxles prior
to filling with oil. This will allow the transaxles to
vent during oil fill.
9. Remove the cap from the transaxles’ expansion
tank located on the vehicle frame.
10. Fill with 20W50 motor oil until oil just appears
at the bottom of each transaxles’ top port
(approximately 2 quarts per transaxle, 4 quarts
total). Install the top port lug into each transaxle
as the oil level reaches the port.
11. Install and torque the top port plugs to 180 in./lbs.
12. Continue to fill the transaxles through the
expansion tank until the FULL COLD line is
reached (this will take approximately 23 additional
ounces).
13. Reinstall the expansion tank cap by hand. Be
careful to not overtighten.

STORAGE
Winter Storage
The machine should be readied for storage at the
end of the mowing season 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
can cause serious personal injury and
property damage. Drain the fuel into an
approved container outdoors and far
away from open flame. Store the fuel
away from any open flame or source of
ignition.
To ready the machine for 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.
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 the machine
performs its best the following season.
Never use gasoline for cleaning. Use
a degreaser and warm water.
