CONTROLS

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.

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.

CONTROLS

Fuel Tank

Read the safety instructions before refueling. The
capacity for the tank is 5 gallons (19 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 Technical
Data concerning ethanol fuel. Methanol fuel is not
allowed. Do not use E85 alcohol based fuel. Damage
to the engine and components may occur.

When operating in temperatures below 32° F. (0° C.),
use fresh, clean winter grade gasoline to help insure
good cold weather starting.

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.

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.

Gasoline 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.

Hydro Release Levers

Transaxle bypass linkages must be engaged when
pushing or pulling the mower. The release levers are
located on each side of the rear of the unit below
the rear engine plate. See Manual Transport in the
Operation section.

WARNING!

Bypass linkages are located close to the
muffler. To prevent burns, the engine
should be shut off and allowed to cool
before the bypass linkage levels are
handled.

OPERATION

Read the Safety Instructions section and the
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.

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 Moving
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, 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.

24

OPERATION

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 and that the deck
is cleaned more often.

WARNING!

Clear the lawn of stones and other
objects that can be thrown out by the
blades.

8011-603b

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.

MAINTENANCE

Adjusting the Mower Deck

Check the tire pressure before adjustment of the
mower deck. See Tire Pressures in Maintenance
section. Faulty mower deck adjustments will cause an
uneven mowing result.

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, you cannot properly adjust
your deck.

Four slots control the height and pitch of the mower
deck. 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 with the deck side-to-side.

2. Measure from the floor surface up to the bottom
of the blade tip on the discharge side of the
mower deck. Retain this measurement. Move to
the opposite side, check that measurement is the
same. If adjustment is required, loosen the locknut
and move mounting bolt up or down in slot until
both side-to-side measurements are equal. Retain
measurement.

3. Turn both outer blades to align with the deck in
front-to-rear manner. Reposition rear mounting
bolts up or down until rear of mower deck is
positioned level to 1/8" higher in the rear than the
side-to-side measurement.

4. Confirm measurements once again. Blade tips
should be level in a side-to-side manner. In the
rear, blade tips should be level to 1/8" higher than
side-to-side measurement. In the front, blade
tips should be level to 1/8" lower than 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.

Set blades to begin leveling.

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.

Anti-scalp rollers can be set in three positions:

• Upper position 1½ to 3" (38 to 76 mm) grass.

• Middle position 3" to 4½" (76 to 114 mm) grass.

• Lower position 4½" to 6" (114 to 152 mm) grass.
The rollers should be approximately ¼" (6.5 mm) from

ground. Do not adjust the rollers to support the deck.

8058-054

Anti-scalp rollers

IMPORTANT INFORMATION

To avoid deck damage, the anti-scalp rollers
must not be adjusted to support the deck.

43

MAINTENANCE

Caster Wheels

Check every 200 hours. Check that wheels rotate
freely.

IMPORTANT INFORMATION

DO NOT add any type of tire liner or foam fill
material to the tires. Excessive loads created
by foam tires will cause premature failures.

Use only O.E.M. specified tires.

Removal and Installation

Remove nut and caster bolt. Pull the wheel out of the
fork.

To reInstall, reverse the order. Tighten caster bolt.
If wheels do not rotate freely, take the unit to the

dealer for service.

Hardware

Check daily. Inspect the entire machine for loose or
missing hardware.

Cleaning

Regular cleaning and washing, 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 dirt 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 deck and 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.

Do not rinse hot surfaces with cold water. Let unit cool
before washing.

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.

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.

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 plug 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.

2

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.

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 a stabilizer has been added.

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
outdoors, into an approved container.
Store the fuel away from open flame
or any source of ignition. Never use
gasoline for cleaning. Use a degreaser
and warm water.

To ready the machine for storage, follow these steps:

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.
