Warning! When using the mower,

approved personal protective equipment must be used. Personal protective equipment cannot prevent the risk of injury but it will decrease the degree of injury if an accident does occur. Speak to your retailer for help in choosing the right equipment.

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 slopes requires much more caution. If you feel uneasy, do not mow it.

• Mow up and down slopes (15 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.

• Select 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.

• Do not use on steep slopes.

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

embankments.

• Do not bypass transmission or let the transmission free-wheel when on a slope.

Warning! Do not drive up or down hills

with slopes greater than 15 degrees. Do not drive across slopes.

Safe Handling of Gasoline

To prevent personal injury or property damage, use much more care in handling gasoline.

Gasoline is very ammable and the vapors are

explosive.

• Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

• Do not fuel the machine indoors.

• Use only approved gasoline containers.

• Do not remove the gas cap or add fuel with the engine running. Let the engine cool before refueling.

• Do not keep the machine or fuel container where there is an open ame, spark or pilot

light such as on a water heater or other appliance.

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 cool before refueling.

• 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.

SAFETY

• 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.

• Before refueling, minimize the risk of static electricity by touching a metal surface.

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

trailer bed with plastic liner. Place containers on

the ground away from the vehicle when lling.

• Do not overll fuel tank. Fill the tank to the bottom of ller neck.

IMPORTANT DO NOT OVERFILL! This equipment and/or its engine may include evaporative emissions control system components, required to meet EPA and/ or CARB regulations, that will only function

properly when the fuel tank has been lled to the recommended level. Overlling may cause

permanent damage to evaporative emissions control system components.

• Replace the gas cap and tighten securely.

• If fuel is spilled on clothing, change clothing

immediately.

• 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.

• Check the fuel level before each use and leave space for the fuel to expand, as the heat from the engine and the sun may otherwise cause

the fuel to expand and overow.

General Maintenance

• Do not use the machine indoors or in spaces lacking proper ventilation. The exhaust fumes contain carbon monoxide, an odorless and poisonous lethal gas.

• Make sure that the equipment is in good condition and that all nuts and bolts, especially those fastening the blade attachments, are properly tightened and torqued.

• Maintain or replace safety and instruction labels as necessary.

• Do not interfere with the intended function of a safety device or reduce the protection provided by a safety device. Check their proper operation

regularly. NEVER operate a machine with a safety device that does not function properly.

• To reduce the risk of re, keep the machine free

of grass, leaves or other debris buildup. Clean oil or fuel spills and remove fuel-soaked debris. Let machine cool before storing.

• Stop to inspect the equipment if you run over or into anything. If necessary, make repairs before starting.

• Do not make adjustments or repairs with the engine running.

• The blades are sharp and can cause cuts and gashes. Wrap blades or use protective gloves when handling them.

• Check the park brake’s functionality regularly. Adjust and service as necessary.

• Do not work with the starter circuit if there is spilled fuel.

• Make sure that the fuel ller cap is mounted tightly and no ammable substances are kept in

an open vessel.

• Sparking can occur when working with the battery and the heavy cables of the starter

circuit. This can cause battery explosion, re

or eye injury. Sparking will not occur after the grounding cable (normally negative, black) is removed from the battery.

• Disconnect the grounding cable from the battery rst and reconnect it last.

• Do not make a bridge short circuit across the

starter relay to run the starter.

• Be very careful when handling battery acid. Acid on skin can cause serious corrosive burns. If you spill battery acid on your skin, rinse immediately with water.

• Acid in the eyes can cause blindness, contact a doctor immediately.

• Be careful when servicing the battery. Explosive gases form in the battery. Do not perform maintenance on the battery when smoking or

near open ames or sparks. The battery can

explode and cause serious injury or damage.

• The machine is tested and approved only with the equipment originally provided or recommended by the manufacturer. Only use approved repair parts for the machine.

• Regularly clean the deck and the underside of the deck. Do not spray the engine and electrical components with water.

CAUTION! Use protective glasses for maintenance work.

SAFETY

CONTROLS

Steering Controls

The machine’s direction is variable using the two steering controls. The steering controls can be moved forward and back from a neutral position. See Steering in the Operation section.

Operator Presence Control

Located on the left steering control, the Operator Presence Control (OPC) lever is an added safety feature. An electrical interlock safety system is engaged when the lever is held against the left hand steering control. When either the blades or the speed control are engaged, the lever must be held against the steering control to keep the engine running.

Safety handle / speed control

Located below the steering controls, the safety handle can be adjusted to change ground speeds and grip span. Use the speed adjustment lock to move the handle closer to (for slower speed) or away from (for faster speed) the steering controls.

Speed adjustment lock

Located on the left hand side, the speed adjustment lock adjusts the safety handle / speed control.

Throttle Control

The throttle control regulates the engine speed and the rate of rotation of the blades, when the blade switch is engaged.

To increase or decrease the engine speed, the control is moved forward or back.

To prevent fouling the spark plugs, do not idle the engine for long periods. USE FULL THROTTLE WHEN MOWING, for best mower performance and battery charging.

Ignition

The ignition switch has three positions— Stop, Start and Run.

CONTROLS

Blade Switch

To engage the mower deck, pull the knob out; mower blades are disengaged when the knob is pressed down.

Service Meter

The service meter displays the total operating time.

NOTE: The service meter operates (clocks hours) only when the engine is running. Be sure to turn the key off when the mower is not in use, to prevent meter hours from accumulating.

Choke Control

The choke control is used for cold starts to provide the engine with a richer fuel mixture.

For cold starts, pull the control up.

Park Brake

The park brake is found on the right of the machine. Pull the lever back to engage the brake and push forward to release it.

IMPORTANT The machine must stand still when engaging the park brake. Release the park brake before moving the mower.

Hydraulic Pump Bypass Valves

Bypass valves are used to release the system so the machine may be moved by hand when not running. See Moving Machine By Hand in the Maintenance section.

Warning! Bypass linkages are located

close to the engine. To prevent burns, the engine should be shut off and allowed to cool before adjusting the valves.

CONTROLS

Fuel Tank

Read the safety instructions before refueling. The capacity for the tank is 5.8 gallons (22 liters).

Regularly check the gas cap gasket for damage and keep the cap correctly tightened.

The engine will operate 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 permitted. Do not use E85 alcohol based fuel. Damage to the engine and components may occur.

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

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.

Warning! Fill to the bottom of the ller

neck. Do not overll. Clean off spilled oil or fuel.

Do not keep, spill or use gasoline near an open

ame.

Warning! Gasoline is highly ammable.

Observe caution and ll the tank outdoors

(see Safe Handling of Gasoline in the Safety section).

IMPORTANT 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 prevent 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 operate 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.

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 mowers.

Review this section fully prior to 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 PRIOR to 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.

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

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, letting the mower 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.

Warning! Make sure the work area is

free from objects that could be thrown by the rotating blades. Clean the lawn of stones and other objects.

Before Starting

1. Read the sections on Safety and Controls before starting the machine.

2. Do 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.

Warning! The engine exhaust contains

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

Starting the Engine

1. Adjust the safety bar halfway back and tighten the speed adjustment lock for moderate a mowing speed.

2. Engage the park brake.

3. Disengage the mower blades by pressing the blade switch down.

4. Move the throttle lever to the mid throttle position. If the engine is cold, the choke control should be pulled up.

OPERATION

5. Push in and turn the ignition key to the start position.

IMPORTANT Do not operate the starter for

more than ve seconds each time. If the engine

does not start, wait approximately ten seconds before retrying.

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

7. Set the engine speed with the throttle. Let the engine to run at a moderate speed, approximately mid throttle, for a short time before use. USE FULL THROTTLE WHEN MOWING (no choke).

Running

1. Move throttle control to full throttle (rabbit symbol).

2. Engage the OPC lever.

3. Release the park brake.

4. Engage the mower deck by pulling the blade switch up.

Warning! Make sure that no one is near

mower when engaging blade switch.

5. Grasp the safety bar and move the steering controls to start movement.

NOTE: When mowing in reverse, use the smaller safety bar at the rear of the console.

Stopping

1. Move the steering controls back to the neutral position and release the OPC lever.

2. Disengage the mower deck by pressing the blade switch down.

3. Move the throttle to the minimum position (tortoise symbol).

4. Engage the park brake.

5. Turn the ignition key to the stop position and remove key. Remove the key when leaving the mower to prevent unapproved use.

Operating on Hills

Read the Safety Instructions Slope Operation in the Safety section.

• Use the slowest speed possible before starting up or down hills.

• Prevent stopping or changing speed on hills.

• If stopping is fully necessary, pull steering / park

brake controls into the neutral position and push outward to engage the park brake.

• Pull the steering / park brake controls back to the center of the mower and push forward to regain forward movement.

• Make all turns slowly.

Warning! Do not use the mower on

terrain that slopes more than 15 degrees. Mow slopes up and down, never side to side. Prevent sudden directional changes. Do not mow across slopes.

Mowing Tips

• Observe and ag rocks and other xed objects

to prevent collisions.

• Start with a high cutting height and reduce it until getting the desired mowing result. Cut the average lawn to 2-1/2" (6.35 cm) during the cool season and over 3" (7.6 cm) during the hot months. For healthier and better looking lawns, mow often after moderate growth.

• For best cutting performance, grass over 6" in height must be mowed 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 speed can be increased without having a negative effect on the mowing result.

OPERATION

• The nest lawns are obtained by mowing

often. The lawn becomes more even and the grass clippings more equally distributed over the mown area. The total time taken is not increased as a higher operating speed can be used without poor mowing results.

• Do not mow wet lawns. The mowing result is poorer because the wheels sink into the soft lawn, clumps build, and grass clippings fasten under the cowling.

• 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.

• Clean the mower deck underside with water

after each use. Make sure the mower is cooled and the engine is off.

• Use compressed air to clean top surface of the deck. Do not ood water on the top surface,

engine and electrical components.

Moving Machine By Hand

When pushing or pulling the mower when the engine is not running, engage the bypass valves.

CAUTION! With the bypass valves open,

the mower will have unrestricted motion if the parking brake is not engaged. Do not open the bypass valves when the mower is not on a level surface.

1. Park on a level surface and engage the park brake.

2. Move the steering / park brake controls inwards to the neutral position.

3. Turn the two bypass valves counter clockwise (as you are facing the mower) one full turn to the open position.

4. Release the park brake and push the mower to the desired location

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

MAINTENANCE

Clutch Adjustment

If the clutch fails to engage or disengage correctly or makes unusual noise, it may need adjustment. Stop the engine and let the mower cool. Check the inspection slots and air gaps. See a service workshop for adjustments.

Cutting Blades

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

Let the service workshop decide whether a blade with large nicks can be repaired/ground or must be replaced.

CAUTION! Blades are sharp. Protect hands with gloves and/ or wind heavy cloth around the blades before handling.

IMPORTANT Special blade bolts are heat treated. Replace with a Husqvarna bolt if required. Do not use lower grade hardware

than specied.

Checking for Bent Blades

1. Park on a level surface and engage the park brake.

2. Measure the distance between the blade tip and the ground surface.

3. Rotate the blade 180° and measure the same distance again.

4. If the difference between the two blade measurements is more than 1/8" (3 mm), a blade must be replaced.

5. Repeat on the other blade.

Replacing the Blades

2. Remove the bolt, blade and spacer from the spindle shaft.

3. Install the replacement blade, reversing the order of removal.

4. Remove the wooden block.

IMPORTANT Blade sharpening of must be carried out by an approved service workshop. Balance the blades after sharpening.

Cleaning

Regular cleaning, especially under the mower deck, will increase the machine’s life-span. 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 the mower deck. Do not use a high pressure washer or steam cleaner. Do not spray the engine or electrical components with water.

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

Hardware

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

LUBRICATION

General

Remove the ignition key to prevent unintentional movements during lubrication.

When lubricating with an oil can, it must be lled

with engine oil. When lubricating with grease, unless otherwise stated, use a high grade molybdenum disulphide grease.

For daily use, the machine must be lubricated twice weekly. Clean away unwanted grease after lubrication.

It is important to prevent lubricant from getting on the belts or the drive surfaces of the belt pulleys. If this happens, try to clean them with spirits. If the belt continues to slip after cleaning, the belt must be replaced. Gasoline or other petroleum products must not be used to clean belts.

IMPORTANT Use minimal lubrication and remove excess lubricant so that is does not come into contact with belts or belt pulley drive surfaces.

Warning! Escaping hydraulic oil under

pressure can have sufcient force to penetrate

the skin, causing dangerous injury. If injured

by escaping uid, see a doctor immediately.

Dangerous infection or reaction can develop if proper medical treatment is not administered.

IMPORTANT Check the engine oil level again if the engine runs over four hours in a day. Do not operate the engine with the oil level below the ADD mark or over the FULL mark.

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 more than 30 days. Fuel that stands for long periods of time (30 days or more) can leave sticky residues that can clog the carburetor and disrupt engine function.

Fuel stabilizers are a satisfactory option to prevent the sticky residues that can occur during storage.

Add stabilizer to the fuel in the tank or in the

storage container. Use the mixing ratios specied

by the manufacturer of the stabilizer. Operate 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 stabilizer has been added.

To ready the machine for storage:

1. Thoroughly clean the machine, especially below the mower deck. Touch up damage to the paint and spray a thin layer of oil on the underside of the mower deck to prevent 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 correctly.

4. Empty the fuel tank or add a fuel stabilizer. Start the engine and let it operate until the carburetor is drained of fuel or the stabilizer has reached the carburetor.

5. Remove the spark plug and put 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 keep the battery in a cool area and protected from direct cold.

8. Keep the machine in a clean, dry area and cover it for more protection.

Service

When ordering spare parts, please specify the purchase year, model, type, and serial number.

Use genuine Husqvarna spare parts. An annual check-up at an approved service

workshop is a good way to make sure that your machine performs its best the next season.

Warning! Do not keep 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 caution. It is very

ammable and can cause dangerous personal

injury and property damage. Drain the fuel into an approved container outdoors and

keep far away from open ame or sources of

ignition. Do not use gasoline for cleaning. Use a degreaser and warm water.
