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.

• Avoid starting, stopping, or turning on a slope. If
the tires lose traction, disengage the blades and
proceed slowly straight down the slope.

• Keep movement on the slopes slow and gradual.
Do not make sudden changes in speed or
direction, which could cause machine to roll over.

• Use extra care while operating machine with
grass catchers or other attachments; they can
affect the stability of the machine.

• Do not use on steep slopes.

WARNING!

Do not drive up or down hills with slopes
greater than 10 degrees. And do not drive
across any slopes.

Mow up and down, not side to side

SAFETY

Safety System

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 blades are disengaged.

• The park brake is on.

• The motion control levers are in neutral.
After the machine is started, the engine will continue

to run for five minutes if the operator leaves the
seat after setting the park brake. The blades will be
disengaged by the safety system. This allows the
operator to leave the machine momentarily to remove
obstacles from the mowing path without having to re­enter the passcode.

The blade switch light will blink until the blade switch
is disengaged. See Ignition System Faults in the
Operation section. When the operator returns to the
seat, the blade switch will need to be reset (pushed
down, pulled up ) to re-engage the blades.

8058-241

Conditions for starting

If the park brake is not engaged before the operator
leaves the seat, the engine and blades will shut down
and the blade switch and park brake lights will blink,
signalling a safety system fault.

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.

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.

Service Minder

The service minder displays the total number of hours
the engine has run and indicates when the engine
and mower need servicing.

After every 50 hours of operation, an oil can icon will
appear and stay on for two hours, before an automatic
reset occurs. To service the engine and mower, see
the Service Journal of this manual.

Note: The service minder operates (clocks hours) only
when the engine is running or when the SmartSwitch
is active (unlocked).

Tracking Knob

If the mower is not tracking straight, check the
air pressure in both rear tires. Recommended air
pressure is 15 psi (103 kPa / 1 bar) for all tires.

automobiles.

Fuel Tank

Read the safety instructions before refueling. The
machine has one fuel tank, just behind the console.
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 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.

When operating in temperatures below 32° F. (0° C.),
use fresh, clean winter grade gasoline to 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.

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

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.

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 park
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.

one or both headlights are not working.

The headlights can also be used when the ignition
switch is not activated or the unit is not running. Press
Button 2 and the headlights will stay lit for one minute.

For a longer headlight mode, press and hold the
button for five seconds. The headlights will flash twice
to acknowledge and will stay on for five minutes.

MAINTENANCE

Tire Pressures

All tires should be at 15 psi / 103 kPa / 1 bar.

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.

Only use O.E.M. specified tires.

IMPORTANT INFORMATION

Adjust anti-scalp rollers with the mower on a
flat level surface.

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.

Anti-scalp rollers can be set in four positions. The
rollers should be approximately ¼" (6.5 mm) from
ground. Do not adjust the rollers to support the deck.

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.

MAINTENANCE

Adjusting the Mower Deck

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 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. Record this measurement.

3. Move to the opposite side, check that the
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 side-to-side measurements are equal.

80158-166

Set blades to begin alignment

4. Turn either outer blade to align with the deck in
front-to-rear manner. If the front blade tip does
not measure 1/8" to ½" higher in the rear, follow the
front adjustment instructions that follow.

5. 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

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.

Hardware

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

IMPORTANT INFORMATION

Use protective glasses when
cleaning and washing.

IMPORTANT INFORMATION

Make sure no children are in the area when
using the cleanout port.

Clean regularly

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 ten 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 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. Never use
gasoline for cleaning. Use a degreaser
and warm water instead.

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 your machine
performs its best the following season.
