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,

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.

OPERATION

Read the Safety 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 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, the

mower turns to the direction of the reverse position

lever,

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 21/2'' (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,

_l_ ARNINGt

Clear the lawn of stones and other

objects that can be thrown out by the

blades,

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 the

tires are under or over inflated, the deck cannot be

properly adjusted.

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

either align with the deck (1) or side-to-side (2).

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. Move to

the opposite side, check that measurement is the

same. If adjustment is required, loosen the Iocknut

and move mounting bolt up or down in slot until

both side-to-side measurements are equal.

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. Additional adjustments may

be required to achieve the desired cut for the type of

Adjust anti-scalp rollers with the mower on a

flat level surface.

Anti-scalp rollers can be set in three positions:

• Upper position 11/2to 3" (38 to 76 mm) grass.

• Middle position 3" to 41/2'' (76 to 114 mm) grass.

• Lower position 41/2'' to 6" (114 to 152 mm) grass.

The rollers should be approximately 1/4"(6.5 mm) from

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

Anti-scalp rollers

IMPORTANT INFORMATION

To avoid deck damage, the anti-scalp rollers

must not be adjusted to support the deck.

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,

Use protective glasses when

cleaning and washing.

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 debris sticks,

Use compressed air to clean the top side of mower

deck. For cleaning the underside of the deck, use the

cleanout port,

Attach the connect coupler (from the accessory

packet) to any garden hose. After mowing, snap the

hose to the cleanout port on the deck and turn on the

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,

Avoid spraying water on the engine and electrical

components.

When cleaning is complete, turn off the engine, turn

off the water supply to the hose and disconnect the

connect coupler from the deck,

Allow the mower to dry completely before storage,

Clean regularly

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 1/4"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.

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./Ibs.

12. Continue to fill the transaxles through the

expansion tank until the FULL COLD line is

reached (approximately 23 additional ounces).

13. Reinstall the expansion tank cap by hand. Do not

overtighten.

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.

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 three-

quarters to one full turn after the filter gasket

contacts the filter base surface.

5. Reinstall the filter guard. Torque screws to

65 in/Ibs, 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 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 used 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.

WARNINGt

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, 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.
