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. There is a neutral position, which is locked if the steering controls are moved out.
When both controls are in the neutral position (N), the machine stands still.
By equally moving both controls forward or backward, the machine moves in a straight line forward or backward.
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 more 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 out, they can be adjusted.
WARNING! The machine can turn very rapidly if one steering control is moved much further forward than the other.

Park Brake

The park brake is integrated with the steering control levers. Move both levers out from the neutral position to engage the park brake.
To release the park brake, pull both steering control levers inwards to the neutral position at the same time. Do not try to operate the unit without both levers being inwards out of the engaged position or machine components could be damaged.
IMPORTANT INFORMATION Failure to bring the steering / park brake controls inward at the same time will cause the unit’s safety system to shut the unit down.

Ignition Switch

The ignition switch is placed on the control panel and is used to start and stop the engine.

Throttle Control

The throttle control regulates the engine speed and thereby the rate of rotation of the blades, assuming the blade switch is pulled out.
To increase or decrease the engine speed, the control is moved forward or back respectively.
Avoid idling the engine for long periods, as there is a risk of fouling the spark plugs. USE FULL THROTTLE WHEN MOWING, for best mower performance and battery charging.

Choke control

The choke control is used for cold starts to provide the engine with a richer fuel mixture.
For cold starts the control should be pulled up.

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 with the blade activated.
At 50 hour intervals of operation, an oil can icon shows and stays on for two hours before an automatic reset occurs. To manually reset the meter, turn the key off and on five times at one second intervals. To service the engine and mower, see the Service Journal of this manual.
Note: The service meter operates (clocks hours) only when the engine is running. Be sure to turn the key off when the unit is not in use, to prevent meter hours from accumulating.

Fuse

The 20 amp primary fuse is located on the left hand side of the machine. It is accessed by tilting the seat forward. The fuse is a flat pin type used in automobiles.

Fuel Shut Off Valve

The fuel shut off valve is located at the right rear of the seat. The valve is off when the handle tab is turned perpendicular to the fuel line.

Cutting Height Lever

To set the deck cutting height, pull the cutting height lever inwards and move it to the desired height notch.
IMPORTANT INFORMATION Always raise the deck to the highest position for transport.
IMPORTANT INFORMATION To obtain an even cutting height, it is important that the air pressure in all tires is 15 psi / 103 kPa / 1 bar.

Bypass Linkages

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 guard. See Moving Machine By Hand 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 levers are handled.

To Adjust The Seat

Lift seat up and remove seat adjustment knob (A).
Loosen seat adjustment knob (B).
- IMPORTANT INFORMATION Do not remove seat adjustment knob (B).
Move seat to necessary position, line up the hole in the seat pan for seat adjustment knob (A) with the hole in the seat.
Install and tighten seat adjustment knob (A).
Tighten seat adjustment knob (B).

Fuel Tank

Read the safety instructions before refueling. The capacity for each tank is 3-1/2 gallons.
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 allowed. Do not use E85 alcohol based fuel. Damage to the engine and components may occur.
When operating in temperatures below 32° F, 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 bottom of filler neck. Do not overfill. Clean off spilled oil or fuel. Do not store, spill or use gasoline near an open flame.
WARNING! Gasoline is highly flammable. Observe caution and fill the tank outdoors (see Safe Handling of Gasoline in the Safety section).
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 operate until the fuel lines and carburetor are empty. Use fresh fuel the next season. See Storage for additional information. Do not use engine or carburetor cleaners in the fuel tank or permanent damage may occur.

Tracking

If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure for the rear tires is 15 psi (1 bar).
Tracking adjustments are made using the tracking bolts. The tracking bolts limit the motion control levers when in the full-forward position.

For preliminary tracking adjustment, move unit to an open, unobstructed area such as an empty parking lot or open field.
Using a 1/2″ wrench, back the tracking bolts out until flush with nut.
Test operate unit by driving it at full throttle and the full forward position on both motion control levers. Gradually turn in the tracking bolt on the right hand side until the unit noticeably starts drifting right.
Drive forward at full throttle with both motion control levers in the full forward position. Gradually turn in the left tracking bolt until unit tracks straight.

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.
Review this section fully prior to trying 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 must become familiar with the mower’s movement on a hard surface, such as concrete or blacktop PRIOR to trying 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 must push the mower (see Moving Machine By Hand in the Operation section) to an open, flat area without other persons, 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. Pull 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 let the mower start moving forward in a straight line. Pull 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. Push the control levers forward 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, 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.
WARNING! Make sure the work area is free from objects that could be thrown by the rotating blades. Clear the lawn of stones and other objects.

Before Starting

Read the sections on Safety and Controls before starting the machine.
Do the daily maintenance before starting (see Maintenance Schedule in the Maintenance section).
Check that there is sufficient fuel in the fuel tank.
Adjust the seat to the desired position.

IMPORTANT INFORMATION The seat should not be adjusted while the unit is in motion.
The following conditions must be fulfilled before the engine can be started:
The blade switch must be pressed down into the disengaged position.
Both steering / park brake controls must be in the locked (outer) position.
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

Sit on the seat.
Raise the mower deck to the highest position.
Disengage the mower blades by pressing the blade switch downwards.
Move the steering / park brake controls firmly out to the locked position.
Move the throttle lever to the middle throttle position. If the engine is cold, the choke control should be pulled up.
Push in and turn the ignition key to the start position.

IMPORTANT INFORMATION Do not operate the starter for more than five seconds each time. If the engine does not start, wait approximately ten seconds before retrying.

When the engine starts, immediately release the ignition key back to the run position.

Running

Release the park brake by pulling the steering / park brake controls inwards to the neutral position at the same time.
- NOTE: The mower is equipped with an operator presence system. If the operator tries to leave the seat with the engine running, without first setting the park brake, the engine will shut off.
Lower the mower deck to the desired cutting height.
Move throttle control to full throttle (rabbit symbol).
Engage the mower deck by pulling the blade switch up.
- WARNING! Make sure that no one is near mower when engaging blade switch.
Pull control levers inward and slowly move both control levers slightly forward to move forward in a straight line.

IMPORTANT INFORMATION When stopping and leaving the machine, both steering / park brake controls must be moved out to the locked position at the same time.

Stopping the Engine

Move the throttle to the minimum position (tortoise symbol).
Move the steering controls at the same time out to the park brake position.
Disengage the mower deck by pressing the blade switch down.
Raise the mower deck to the highest position. If the engine has been worked hard, let it idle at least 60 seconds to attain a usual operating temperature before stopping. To prevent fouling the spark plugs, avoid idling the engine for longer periods.
Turn the ignition key to the stop position. Remove key. Always remove key when leaving the mower to prevent unauthorized use.

IMPORTANT INFORMATION Leaving the ignition switch in a position than OFF will cause the battery to be discharged.

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.
Avoid 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 drive the rider on terrain that slopes more than 10 degrees. Mow slopes up and down, never side to side. Avoid sudden directional changes. Do not drive across slopes.

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 must be cut to 2-1/2″ during the cool season and over 3″ 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 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 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.
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.
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 finished.
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.

Moving Machine By Hand

WARNING! Make no adjustments without:
the engine stopped,
the park brake activated
IMPORTANT INFORMATION To manually push the mower, engage the hydro bypass levers on both sides, pull both steering / park brake controls inwards and push machine.
When pushing or pulling the mower, engage the EZT bypass linkages. The EZT bypass linkages are located on the rear of the frame, below the rear engine guard.

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 deck is disengaged.
the steering / park brake controls are in the outer, locked neutral position, making sure of full parking brake engagement for a safe startup.
NOTE: If the steering / park brake controls are not holding in the full outboard position, the tension can be adjusted by tightening the nut on the backside of the pivot. (See Park Brake in this section).
Make daily inspections to make sure that the safety system works by trying to start the engine when one of the conditions is not met. Change the conditions and try again.
If the machine starts when one of these conditions is not met, turn the machine off and repair the safety system before using the machine again.
Make sure the engine stops when the park brake is not engaged and the operator leaves the seated position.
Check that the engine stops if the mower blades are engaged and the driver temporarily moves off the drivers seat.
IMPORTANT INFORMATION To be able to drive, the driver must sit in the seat and the steering / park brake controls must be moved into the engaged (outer) position. Otherwise the engine will stop.

Park Brake

Visually check that no damage is found on the steering control levers, links or switches belonging to the park brake. Do a standstill test and check that there is sufficient braking action.
To adjust the park brake tension, move the boot covering the steering control base. Tighten the 1/2″ pivot nut until the braking action is correct.
Replace the steering boot, making sure the boot top sits between the two adjustment bolts on the steering control.
For any further adjust to the park brake, contact the Husqvarna service workshop.
IMPORTANT INFORMATION The machine must be standing still when applying the park brake.
WARNING! Faulty adjustment will result in reduced braking ability and can cause an accident.

Tire Pressures

All tires must be at 15 psi / 103 kPa / 1 bar.
IMPORTANT INFORMATION DO NOT add a 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.

Caster Wheels

Check at 200 hour intervals. Check that wheels turn freely. If wheels do not turn freely take the unit to your dealer for service.
Foam filled tires or solid tires will void the warranty.
Removal and installation
Remove nut, washer and caster bolt. Pull the wheel out of the yoke and take care of the spacers.
Install in reverse order. Tighten caster bolt.

V-belts

Check the belts every 100 hours of operation.
Check for severe cracking and large nicks.
The belt will show some small cracks in normal operation. The belts are not adjustable. Replace the belts if they begin to slip from wear.

Deck Belt Removal

Park on a level surface and apply the parking brake.
Lower the deck to the lowest cutting position.
Remove both belt shields.
Remove the debris that has accumulated around the cutter housings and the deck surface.
Loosen the nut securing the belt guide. Note the position of the belt guide for reinstallation
Push inward on the idler arm to release the tension on the belt.
Slip the belt over the top of the cutter housing pulleys and remove the belt from the deck.

Deck Belt Installation

NOTE: For ease in installing the deck belt, refer to the routing decal on the top of the deck.

Wrap the deck belt around the electric clutch pulley located on the engine shaft.
Route the belt forward and up onto the deck.
Place the belt around the spring loaded idler pulley.
Wrap the belt around the stationary idler pulley and around the mandrel housings.
Push inward on the idler arm and carefully route the belt over the stationary idler pulley.
- Once the belt is properly routed, slowly release the idler arm to tension the belt.
Make sure the belt routing matches the deck decal and that the belt does not have any twists.
Tighten the belt guide and replace the belt shields on both mandrel housings. The belt guide should be perpendicular to the belt when installation is complete.

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 correctly adjusted. Raise the deck to the highest (transport) position.
The deck must be adjusted slightly higher in the rear.

NOTE: To insure the precision of the leveling procedure, the mower deck drive belt must be installed before leveling the deck.

Wear heavy gloves. Turn each outer blade tip to align front to rear with the deck side-to-side.
Measure from the floor surface up to the bottom of the blade tip on the discharge side of the mower deck. Record the measurement.
Move to the opposite side, check that measurement is the same. If adjustment is required—with a 3/4″ or adjustable wrench, turn the lift link adjustment nuts on either side counter clockwise to lower or clockwise to raise. Adjust until both measurements are equal.
Turn either blade to align with the deck frontto- rear. If the front blade tip does not measure 1/4″ to 3/8″ lower than the rear, remove the foot plate access the front deck adjustment. With an adjustable wrench, loosen the rear jam nut on the front suspension linkage.

Make adjustment to level with the front lift link nut. Clockwise raises the front of the mower, counter clockwise will lower the front. Adjust the nut until rear blade tip is 1/4″ to 3/8″ higher than the front blade tip.
NOTE: This will position 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 get the desired cut.

Cutting Blades

For the best mowing results, it is important that blades are correctly sharpened and not damaged.
Replace blades that have been bent or cracked when hitting obstacles.
Let the service workshop decide if a blade with large nicks can be repaired/ground or must be replaced. Balance the blades after sharpening.
Check the blade mounts.

Blade replacement

Remove blade bolt by turning counter clockwise.
Install new or resharpened blade with stamped GRASS SIDE facing towards ground/grass (down) or THIS SIDE UP facing deck and cutter housing.
Seat the blade’s opening firmly onto the cutter housing.
Tighten blade bolt securely.
Torque blade bolt to 45-60 ft/lbs (60-81 Nm).

CAUTION! Blades are sharp. Protect your hands with gloves and/or wind heavy cloth around the blades before handling.
The sharpening of blades must be carried out by an authorized service workshop.
IMPORTANT INFORMATION Special blade bolt is heat treated. Replace with a Husqvarna bolt if required. Do not use lower grade hardware than specified.

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. Avoid spraying engine and electrical components with water.
Clean the underside of the deck with normal water pressure. 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.
CAUTION! Use protective glasses when cleaning and washing.

Hardware

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

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 allowed to stand 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 an acceptable option to prevent 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. 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.
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 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 dangerous personal injury and property damage. Drain the fuel into an approved container outdoors and store far away from open flame or sources of ignition. Do not use gasoline for cleaning. Use a degreaser and warm water.

To ready the machine for storage:

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 avoid corrosion.
Inspect the machine for worn or damaged parts and tighten any nuts or screws that may have become loose.
Change the engine oil; dispose correctly.
Empty the fuel tanks 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.
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 refit the spark plug.
Lubricate all grease zerks, joints and axles.
Remove the battery. Clean, charge and store the battery in a cool area and protected from direct cold.
Store 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.
Always use genuine Husqvarna spare parts.
An annual check-up at an authorized service workshop is a good way to make sure that your machine performs its best the following season.
