Slope Operation

Slopes are a major cause related to loss of control and tip-over accidents, which can result in severe injury or death. Operation on slopes requires more care. If you cannot back up the slope or if you feel uneasy on it, do not mow it.

• Mow across slopes (10 degrees maximum), not

up and down.

• Look for holes, ruts, bumps, rocks, or other

hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.

• Select a low ground speed so it will not be

necessary to stop while on the slope.

• Do not mow on wet grass. Tires can lose

traction.

• Avoid starting, stopping, or turning on a slope. If

the tires lose traction, disengage the blades and continue slowly straight down the slope.

• Move slowly and gradually on slopes. Do not

make sudden changes in speed or direction, which could cause machine to tip over.

• Use more care while operating machine with grass catchers or other attachments; the

stability of the machine can be effected.

• Do not use on steep slopes.

• Do not mow near drop-offs, ditches, or

embankments. The machine could suddenly roll over if a wheel is over the edge or the edge caves in.

WARNING! Do not drive across hills with

slopes greater than 10 degrees. Do not drive up or down slopes.

Safe Handling of Gasoline

To avoid personal injury or damage to property, use care in handling gasoline. Gasoline is very ammable and the vapors are explosive.

WARNING! The engine and the exhaust

system become very hot during operation. There is a risk for burns if touched. Let engine and exhaust system to cool before refueling.

• Do not fuel the machine indoors.

• Extinguish all cigarettes, cigars, pipes, and

other sources of ignition.

• Use only approved gasoline containers.

• Do not remove gas cap or add fuel with

the engine running. Let engine cool before refueling.

where there is an open ame, spark or pilot light such as on a water heater or other appliance.

• Before you start refueling, keep the risk of static

electricity to a minimum by touching a metal surface.

• Do not ll containers in a vehicle or on a truck

or trailer bed with plastic liner. Always put containers on the ground away from the vehicle when lling.

• Do not put too much fuel in the tank. Replace

gas cap and tighten securely.

• Remove gas-powered equipment from the truck

or trailer and refuel it on the ground. If this is not possible, refuel such equipment with a portable container, rather than from a gasoline dispenser nozzle.

• Keep the nozzle in contact with the rim of the

fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lockopen device.

• If fuel is spilled on clothing, change clothing

immediately.

SAFETY

Page 9

• Do not start the engine near spilled fuel.

• Do not use gasoline as a cleaning agent.

• If leaks occur in fuel system, the engine must

not be started until problem has been resolved.

WARNING! Fill to bottom of ller neck.

Do not overll. Wipe off spilled oil or fuel. Do not store, spill or use gasoline near an open ame.

The engine will run on a minimum of 87-octane unleaded gasoline (no oil mix). Environmentally adapted alkylate gasoline can be used. See the

Technical Data section in this manual 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 0°C

(32°F), use fresh, clean winter grade gasoline to help insure good cold weather starting.

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 must 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 more information. Do

not use engine or carburetor cleaners in the

fuel tank or permanent damage may occur.

WARNING! The engine and the exhaust

system, become very hot during operation. There is a risk for burns if touched. Let engine and exhaust system to cool before refueling.

CONTROLS

Page 16

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 mowers.

Review this section fully before trying to move the mower under its own power. When rst 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 must become familiar with the

mower’s movement on a hard surface, such as concrete or asphalt BEFORE trying to operate on turf.

Steering

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 lever controls the left wheel. The right lever controls the right wheel.

First time users must push the mower (see Moving Machine By Hand in the Operation

section) to an open, at area without other persons, vehicles or obstacles nearby.

To move forward and back

To move the unit under its own power, start the

engine (see Before Starting in the Operation

section). Adjust the engine speed to idle but do not engage the blades.

Slowly move the two control levers forward slightly. This will let the mower start moving forward in a straight line. Release the control levers back to the neutral position and stop the mower from moving.

Pull back slightly on control levers, allowing the mower to move backwards. Release the control levers to the neutral position to stop the mower from 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, rst pull the two control levers back until the mower stops or slows signicantly. By moving one lever slightly forward and the other in the reverse, complete the turn.

Before Starting

WARNING! Make sure the work area is

free from of stones and other objects that could

be thrown by the rotating blades.

1. Read the sections on Safety and Controls

before starting the machine.

2. Perform the daily maintenance before

starting (see Maintenance Schedule in the

Maintenance section).

3. Check that there is sufcient fuel in the fuel tank.

4. Adjust the mower deck to the desired

cutting height. See Cutting Height in the Maintenance section.

OPERATION

Page 17

Mowing Tips

• Find and ag rocks and other xed objects to

avoid collisions.

• Start with a high cutting height and reduce it

until the desired mowing result is attained. Cut the average lawn to 6.4 cm (2-1/2") during the cool season and over 7.6 cm (3") during the hot months. For healthier and better looking lawns, mow often after moderate growth.

• For best cutting performance, mow grass over

15.2 cm (6") in height twice. Make the rst 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 operator moves slowly). If the grass is not too long and dense, the operating

WARNING! The engine exhaust contains

carbon monoxide, which is a odorless, colorless, poisonous gas. Do not use the machine in enclosed spaces.

The following conditions must be fullled before

the engine can be started:

• The blade switch must be pressed down into

the disengaged position.

• The park brake must be engaged.

• Both steering controls must be in the neutral

position.

Starting the Engine

1. Move the throttle lever to the mid throttle position. If the engine is cold, pull the choke control up.

2. Press in and turn the ignition key to the start position.

IMPORTANT INFORMATION Do not run the

starter for more than ve seconds each time. If the engine does not start, wait approximately ten seconds before trying again.

3. When the engine starts, immediately release the ignition key back to the run position. Slowly push in the choke control knob, if it was used to start a cold engine.

4. 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. USE FULL THROTTLE WHEN MOWING (no choke).

Operating on Hills

Read the Safety Instructions Driving on Slopes in the Safety section.

• Use the slowest speed possible before starting

up or down hills.

• If stopping is fully necessary, pull steering

controls into the neutral position.

• Pull the steering controls back to the center of the mower and push forward to regain forward

movement.

• Try not to stop or change speed on hills.

• Make all turns slowly.

WARNING! Do not use the mower on

terrain that slopes more than 10 degrees. Mow slopes side to side, never up and down. Avoid sudden directional changes.

Moving Machine By Hand

When pushing or pulling the mower with the

engine not running, engage the hydraulic release lever.

speed can be increased without negatively affecting the mowing result.

• The nest 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.

• 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 nished.

• 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 ooding water on top surface, engine and electrical components.

• When the mulching kit is used, it is important

that the mowing interval is more frequent.

WARNING! Do not make adjustments

unless:

• the engine is stopped,

• the park brake is engaged

• the ignition key is removed,

CAUTION! With the hydraulic release

engaged, the mower will have unrestricted motion if the parking brake is not engaged. Do not use the release lever if the mower is not on a level surface.

Access the lever on the left side of the unit. Set the deck to the lowest position when engaging the bypass linkage. To engage, slide the lever out.

Load the machine into truck or trailer by driving up ramps in low gear. DO NOT LIFT! The machine is not intended to be lifted by hand.

WARNING! Use extreme caution when

loading the machine into a truck or trailer using ramps. There is the possibility of serious injury or death if the machine falls off the ramps.

Tracking - Speed

1. Pull the retaining clip out of the vertical control rod.

2. Adjust the nylon coupler until the desired speed is achieved. When the unit tracks straight and is at appropriate maximum forward speed, reinsert the retaining clip to lock the coupler in place.

Adjusting the Mower Deck

Leveling Deck

Adjust the deck while the mower is on a level

surface and raised to transport mode (cutting

height of 5"). Make sure the tires are inated to

the correct pressure. See Tire Pressures in this

section. If tires are under or over inated, the deck cannot be properly adjusted. Faulty mower deck adjustments will cause an uneven mowing result.

Four bolts control the height and pitch of the

mower deck. Adjust the deck slightly higher in the rear.

NOTE: To insure precision in the leveling procedure, mower deck drive belt must be installed prior to leveling the deck.

1. Wear heavy gloves. Turn the blade tips to align with the deck side to side.

Tire Pressures

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

IMPORTANT INFORMATION DO NOT add

a tire liner or foam ll material to the tires. Excessive loads created by foam lled tires will cause premature failures.

Only use O.E.M. specied tires.

MAINTENANCE

Page 24

2. Measure from the oor 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 measurement is the same. If adjustment is required, loosen and adjust the front nuts until the two side to side measurements are equal. Retain measurement.

4. Turn the two outer blades to align with the deck front to rear. Reposition the rear

mounting nuts up or down until the rear blade

tips are positioned 6.4–9.5 mm (1/4"–3/8") higher in the rear than the center blade tips.

Conrm measurements once again. The blade

tip height must be 0.0–1.6 mm (0"–1/16") side

to side.

In the rear, the blade tips must be 6.4–9.5 mm (1/4"–3/8") higher than the front center measurement. In the front, blade tips must be equal from side to side.

NOTE: This will place the mower deck in a standard measurement position. Depending on the type of grass being mowed or environmental conditions, more adjustments may be required to get the desired cut.

Cutting Blades

To attain the best mowing effect, it is important that blades are well sharpened and not damaged. Replace blades that have been bent or cracked when hitting obstacles.

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.

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.

Anti-scalp Rollers

Anti-scalp rollers keep the deck in the proper position to help prevent scalping in most terrain conditions. Do not adjust the rollers to support the deck.

IMPORTANT INFORMATION Adjust anti-scalp

rollers with the mower on a at level surface. To avoid deck damage, the anti-scalp rollers must not be adjusted to support the deck.

Anti-scalp rollers can be set in three positions.

• Upper: 38 mm to 64 mm (1-1/2" to 2-1/2") grass

• Middle: 64 mm to 102 mm (2-1/2" to 4") grass

• Lower: 102 mm to 127 mm (4" – 5") grass

The rollers must be approximately 6.4 mm (1/4") from the ground. Do not adjust the rollers to support the deck.

Blade Replacement

1. Remove blade bolt by turning it counter clockwise.

2. Install new or resharpened blade with the

stamped part number facing towards the

ground/grass (down).

3. Install and tighten blade bolt securely.

4. Torque blade bolt to 122 Nm (90 ft-lb).

IMPORTANT INFORMATION Special blade

bolt is heat treated. Replace with a Husqvarna bolt if required. Do not use lower grade hardware than specied.

Park Brake

WARNING! Faulty adjustment will result

in reduced braking and can cause an accident.

Visually check that no damage is found on the brake arms, cables, or park brake mechanism. Check that there is sufcient braking action.

1. If the park brake is not performing correctly, examine the brake arm pivot. With the park brake disengaged, the brake arm pivot bracket should have approximately 3.2 mm (1/8") of play when lifted from the top of the

Cleaning

CAUTION! Always wear eye

protection when cleaning or washing

the mower.

Regular cleaning and washing, especially under the mower deck, will increase the machine’s lifespan. 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.

Caster Wheels

Check every 200 hours. Check that wheels rotate freely.

To replace, remove nut and caster bolt. Pull the wheel out of the fork. Install in reverse order.

Tighten caster bolt. Torque to 67.8 Nm (50 ft-lb).

NOTE: Tire must rotate freely but axle spacers must not. If wheels do not rotate freely take the unit to the dealer for service.

Neutral Switches

1. Make sure the park brake is engaged.

2. With a 1/2" wrench, loosen the jam nuts on each side of the unit.

3. Adjust the neutral bolt on the left side of the

unit so the plunger on the neutral switch is

ush with the surface of the switch.

4. Go to the right side of the unit and back

the bolt out so the bolt is not contacting the

plunger.

On the right side:

5. Start tightening the right neutral bolt one to

or two turns at a time. Between tightening, attempt to start the unit, but be sure to keep ngers or loose articles of clothing away from the pump fans.

6. Continue tightening the neutral bolt until the

unit attempts to start (it is not necessary to keep the unit running if it fully starts up).

7. Tighten the neutral bolt an additional half to

full turn and then tighten down the jam nut. To prevent bending the bracket, do not over tighten.

On the left side:

8. Loosen the left neutral bolt until it no longer

contacts the plunger on the switch.

9. Tighten the bolt one to two turns and attempt to start the unit between each adjustment. When the unit attempts to start, tighten the

bolt one half to one full turn and tighten the

jam nut.

Winter Storage

The machine must be readied for storage at the end of the mowing season, or if it will not be in use for more than thirty days.

Fuel allowed to stand for long periods of time

(thirty days or more) can leave sticky residues

that can plug the carburetor and disrupt engine

function.

Fuel stabilizers are an permitted 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 specied 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 a stabilizer has been added.

WARNING! Do not store an engine with

fuel in the tank indoors or in poorly ventilated spaces where fuel vapor can come in contact with open ames, sparks, or a pilot light such as in a boiler, hot water tank, clothes dryer, etc. Handle the fuel with care. It is very ammable and can cause serious personal injury and property damage. Drain the fuel into an approved container outdoors and store far away from open ame or sources of ignition. Do not use gasoline for cleaning. Use a degreaser and warm water.

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 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 let it 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 ret 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.
