Steering Control Levers

Steering Control Levers - Step 1
The machine's speed and direction are continuously variable using the two steering controls. The steering controls can be moved forward or back about a neutral position. There is a neutral / parking brake position which sets the parking brake when 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.
Steering Control Levers - Step 2
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.


The machine must stand still when engaging the park brake. Always engage the park brake before dismounting. Release the park brake before moving the mower.


The machine can turn very fast if one steering control is moved much further forward than the other.

Throttle Control

Throttle Control
The throttle controls the engine speed and the rate of rotation of the blades, assuming the blade switch is pulled out.

The control is moved forward or back to increase or decrease the engine speed.

To prevent the risk of 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 Switch

Ignition Switch
The ignition switch is used to start and stop the engine. On models with headlights, turn the key clockwise to ACCESSORY for headlight use.

Choke Control

Choke Control
The choke control is used for cold starts to give the engine a richer fuel mixture. For cold starts, pull the control up.

Blade Switch

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

Service Meter

Service Meter
The service meter displays the total number of hours the engine has run and shows 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 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.

Seat Adjustment

Seat Adjustment
The seat can be adjusted lengthways. The lever under the front edge of the seat is moved to the left (as seen by the driver in the seat), to adjust the seat backward or forward.

Adjustments may be made to seat suspension by turning the center knob.


Seat must not be adjusted while unit is in motion.

Seat Release

Seat Release
The seat can be rotated forward to access the mower battery and hydro gears. Push down on the latch lever to release the seat. Raise the seat until the rod engages.

Fuel Selector

Fuel Selector
The fuel selector is located at the right rear of the seat. The valve has three positions: right tank, left tank and OFF.

Fuses

CONTROLS - Fuses
Fuses are on the right hand side of the machine and are accessed by tilting the seat forward. Fuses are flat pin fuses type as used in automobiles. The 20 A is the primary fuse. The 7.5 A is for the mower deck coupling.


Always raise the deck to the highest position for transport.

Hydro Release Levers

CONTROLS - Hydro Release Levers

Transmission bypass levers must be engaged when pushing or pulling the machine. Transmissions are put into bypass mode by rotating the levers to the horizontal position. The bypass levers are located at the front of both transmissions. See Manual Transport in the Operation section.

Fuel Tanks

CONTROLS -Fuel Tanks
Read the safety instructions before refueling. The capacity for each tank is 6 gallons (22.7 liters).

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


Fill to bottom of filler neck. Do not overfill. Wipe off spilled oil or fuel. Do not store, spill or use gasoline near an open flame.

The engine will run 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) 0°C, use fresh, clean winter grade gasoline to help insure good cold weather starting.

Tracking

CONTROLS - 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).

  1. Tracking adjustments are made using the tracking bolts.
  2. For preliminary tracking adjustment, move unit to an open, unobstructed area such as an empty parking lot or open field.
  3. Turn the tracking bolts in as far as possible.
  4. Back the tracking bolts out 4 full turns. Any more than four turns could damage the unit.
  5. 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.
  6. Drive forward at full throttle with both motion control levers in the full forward position. Gradually turn in the tracking bolt (left side) until unit tracks straight.

Cutting Height Pedal

Cutting Height Pedal
The desired cutting height is set with the height pin. The cutting height pedal releases the deck lift to place the deck at the selected height. For transport, push the lift pedal fully forward until the deck lift latches in the transport (highest) position.


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.


Gasoline is highly flammable. Observe caution and fill the tank outdoors (see the safety section).


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.

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 before 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 asphalt BEFORE trying to operate on turf. Until the operator becomes comfortable with the mower controls and zero turn, overly aggressive maneuvers can damage turf.

Steering

To move forward and rearward

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, 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, do not engage the blades at this time. Pull control levers inward. As long as the control levers have not been moved forward or to the rear, the mower will not move.

Slowly move the two 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 to the rear. 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 the two 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.

Roll Bar

Operate the unit with the roll bar in the raised and locked position and use the seat belt. There is no rollover protection when the roll bar is down. If it is necessary to lower roll bar, do not wear the seat belt. Raise the roll bar as soon as clearance permits.


The seat belt must be used when the roll bar is in upright position.


Make sure the work area is free of stones and other objects that could be thrown by the rotating blades.

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 sufficient fuel in the fuel tank.
  4. Adjust the seat to the desired position.

  • Make all turns slowly.

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

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. Cut the average lawn to 6.35 cm during the cool season and over 7.62 cm during the hot months. For healthier and better looking lawns, mow frequently after moderate growth.
  • For best cutting performance, mow grass over 15.24 cm in height 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 turn 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 frequently. 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 finished.
  • 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 flooding water on top surface, engine and electrical components.
  • When the mulching kit is used, it is important that the mowing interval is frequent.

To make a three-point turn

To make a three-point turn
A correct turn will prevent damage to the lawn. The goal is to turn as you move forward or rearward. Do not turn in a tight circle on a stopped wheel.

  1. After you cut a row, make a slight turn toward the uncut area of grass (A).
  2. Pull back on the levers to stop and reverse (B).
  3. After you complete the turn, pull harder on the lever that faces the previously cut area (B).
  4. Push forward on both control levers to cut the next row (C).

Moving Machine By Hand

When pushing or pulling the mower, engage the bypass levers. The bypass levers are located at the front of each transmission.

  1. Lower the deck if needed.
  2. Move the steering controls inward out of the park brake position.
  3. Lift the seat.
  4. Rotate each bypass lever to the horizontal position.
     Moving Machine By Hand
  5. Lower the seat.
  6. Push the mower using the sturdy feature of the mower's structure. Do not push the mower with the control levers.
  1. To reengage the transmission, rotate the bypass levers to the vertical position.
    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.


Once the bypasses are engaged, and the steering controls are moved in to release the parking brake, the unit is free to roll and potentially injure someone.


Use more care when loading the machine into a truck or trailer using ramps. There is the possibility of dangerous injury or death if the machine falls off the ramps.


Do not make adjustments unless:

  • the engine is stopped,
  • the ignition key is removed,
  • the park brake is engaged

Before performing service or adjustment:

  • Engage the park brake.
  • Place the blade switch in the disengaged position.
  • Turn the ignition switch to OFF position and remove the key.
  • Make sure the blades and all moving parts have completely stopped.


Do not short battery terminals by allowing a wrench or other objects to contact both terminals at the same time. Before connecting battery, remove metal bracelets, wristwatch bands, rings, etc. Positive terminal must be connected first to prevent sparks from accidental grounding.


The mower has a 12-volt negative grounded system. The other vehicle must also be a 12-volt negative grounded system. Do not use your mower to start other vehicles.

Battery

If the battery is too weak to start the engine, it must be recharged.

Jumper Cable Use

  1. Connect each end of the RED cable to the POSITIVE (+) terminal on each battery, taking care not to short against chassis.
  2. Connect one end of the BLACK cable to the NEGATIVE (-) terminal of the fully charged battery.
  3. Connect the other end of the BLACK cable to a good CHASSIS GROUND on the mower with the discharged battery, away from the fuel tank and battery.
     Jumper Cable Use

To remove cables, reverse order

  1. Remove BLACK cable first from chassis and then from the fully charged battery.
  2. Remove RED cable last from both batteries.

The mower has a maintenance free battery and does not need servicing. However, periodic charging of the battery with an automotive type battery charger will extend its life.

    Battery Removal
  3. Using a wrench, disconnect the BLACK battery cable then the RED battery cable.
  4. Carefully remove the battery from the mower and clean if required.
  5. Rinse the battery with plain water and dry.
  6. Clean the terminals and battery cable ends with a wire brush.
  7. Install the new battery with terminals in the same position as the old battery.
  8. Connect RED battery cable first to positive (+) battery terminal.
  9. Connect BLACK grounding cable to negative (-) battery terminal.
  10. Fasten the battery in place with bracket removed in Step 2.


Do not open or remove caps or covers. Adding or checking level of electrolyte is not necessary. Always use two wrenches for the terminal screws.


Always wear eye protection when around batteries.


Lead-acid batteries generate explosive gases. Keep sparks, flame and smoking materials away from batteries.

Safety System

The machine has 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 controls are in the outer, locked neutral / parking brake position.


To be able to drive, the driver must be seated and move both steering levers in toward each other at the same time, otherwise the engine will stop. Make daily inspections to ensure that the safety system works by attempting 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 released 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 driver's seat.

Park Brake and Steering

Visually check that no damage is found on the lever, links, or switches belonging to the park brake. Do a standstill test and check that there is sufficient braking. For park brake adjustments, contact the Husqvarna service workshop.


Faulty adjustment will result in reduced braking and can cause an accident.

Tire Pressures

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


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 tires specified by Husqvarna.

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

  1. Park on a level surface and apply the parking brake. Lower the deck to the lowest cutting position.
  2. Remove both belt shields.
  3. Remove the debris that has accumulated around the cutter housings and the deck surface.
  4. Push inward on the idler arm to release the tension on the belt.
    Deck Belt Removal
  5. 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.

  1. Wrap the deck belt around the electric clutch pulley located on the engine shaft.
  2. Route the belt forward and up onto the deck.
  3. Place the belt around the idler pulley.
  4. Wrap the belt around the stationary idler pulley and around the mandrel housings.
  5. 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.
  6. Make sure the belt routing matches the deck decal and that the belt does not have any twists.
  7. Replace the belt shields on both mandrel housings.

Pump Belt

The transmissions drive belt tension is adjustable. The tension spring should be compressed to a length between 1.38 and 1.50 inches.

Replacing Pump Belt
Park the mower on a level surface. Engage the park brake by moving the steering controls outward.

Belt Removal
From the top side of the deck:

  1. Remove the deck belt (see Deck Belt Removal in this section of the manual).
  2. Tilt seat forward to access fan covers. Remove both fan covers.
    Pump Belt Removal - Step 1

From the underside of the mower:

  1. Remove clutch stop to access the belt.
  2. Loosen tension spring nuts on eyebolt to shift the arm and create slack in the belt.
    Pump Belt Removal - Step 2
  3. Remove belt from the engine and pump pulleys. Lift belt over the top of the fans.

Belt Installation

  1. If the pump is not locked in the extended position, do Step 4 from the above instructions again.
  2. Slip the belt over the fans and put it between the idler pulleys.
  3. Place the belt over the right and left idler pulleys.
  4. Place the belt on the engine pulley.
  5. Install and tighten the clutch stop.
  6. Adjust drive belt linkage tensioner to achieve a spring length between 1.38 and 1.50 inches.
  7. Install the fan shields.
  8. Install the deck belt.

Cutting Blades


Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling.
The sharpening of blades must be carried out by an authorized service workshop.

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 when hitting obstacles.

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.

Blade Replacement

  1. Remove blade bolt by turning it counter clockwise.
  2. Install new or re-sharpened blade with stamped GRASS SIDE facing toward the ground/grass (down) or THIS SIDE UP facing the deck and cutter housing.
  3. Install and tighten the blade bolt correctly.
  4. Torque the blade bolt to 45-55 ft/lb (61-75 Nm).


The special blade bolt is heat treated. Replace it with a Husqvarna bolt if necessary. Do not a use lower grade hardware than specified.

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 Tire Pressures in Maintenance section. If tires are under or over inflated, the deck cannot be correctly adjusted. Faulty mower deck adjustments will cause an uneven mowing result.

Four slots control the height and pitch of the mower deck. Adjust the deck slightly higher in the rear.

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

  1. Wear heavy gloves. Turn each outer blade tip to align with the deck side to side.
    Adjusting the Mower Deck - Step 1
  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 locknut on the top of the rear links and adjust until both side to side measurements are equal. Retain measurement.
    Adjusting the Mower Deck - Step 2
  3. Turn both outer blades to align with the deck front-to-rear. Reposition the front mounting bolts up or down until the rear blade tips are positioned 1/8" to 3/8" higher in the rear than the front blade tips.
  1. Confirm measurements once again. The blade tip height must be equal side-to-side. In the rear, blade tips must be 1/8" to 3/8" higher than the front 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 can be necessary to get the desired cut.

Powertrain

Regular external maintenance of the Powertrain™ should include the following:

  1. Check each transmission oil level. When the engine is cold, the oil level should touch the bottom of each transmission oil dipstick.
  2. Examine the vehicle drive belt, idler pulley(s), and idler spring(s). Ensure that no belt slippage can occur. Slippage can cause low input speed to the transmissions.
  3. Examine each transmission cooling fan for broken or bent blades. Remove any obstructions such as grass clippings, leaves or dirt.
  4. Examine the park brake and vehicle linkage to make sure they work correctly.
  5. Examine the vehicle control linkage to the directional control arm on the transmissions. Also, make sure the control arm is correctly fastened to the trunnion arm of the transmissions.
  6. Examine the bypass levers on the transmissions and make sure they rotate freely.


Any servicing dealer attempting a warranty repair must have prior approval before conducting maintenance of a Parker® product, unless the servicing dealer is a current Authorized Parker™ Service Center.

Caster Wheels

Check every 200 hours. Check that wheels turn freely. Foam filled tires or solid tires will void the warranty.

To replace, remove the nut and caster bolt. Pull the wheel out of the yoke and take care with the spacer. Install in reverse order. Tighten the caster bolt and torque to 45 ft/lb (61 Nm).
Caster Wheels Maintenance

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

Anti-scalp Rollers

Anti-scalp rollers are correctly adjusted when they are slightly off of the ground when the deck is at the desired cutting height. Anti-scalp rollers keep the deck in the correct position to prevent scalping in most terrain conditions. Do not adjust the rollers to support the deck. The rollers must be approximately 1/4" (6.5 mm) from ground.
Anti-scalp Rollers Maintenance


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

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


Always wear eye protection when cleaning and washing.

Hardware

Check daily. Examine the machine for loose or missing hardware.

LUBRICATION

Lubrication Schedule

 Lubrication Schedule

12/12 Every year
1/52 Every Week
1/365 Every day
Lubricate with grease gun
Filter change
Oil change
Level check

*Initial hydraulic oil and filter change at 100 hrs, every 400 hrs thereafter.
Change engine oil every 50 hours

General

Remove the ignition key to prevent unintentional movements during lubrication.

When lubricating with an oil can, it must be filled with engine oil.

When lubricating with grease, unless otherwise stated, use high grade molybdenum disulfide grease.

For daily use, the machine must be lubricated twice weekly.

Wipe away excess grease after lubrication.

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

Qualified Hydraulic Oils
If Parker™ HT-1000 oil is used continually, the oil and filters must be changed every 750 hours. If Castrol™ Syntec 5W-50, Amsoil AW ISO 68, or Shell™ TTF-SB oils are used, the oil and filters must be changed every 500 hours after the initial 750 hour oil and filter change.

If a premium grade synthetic engine oil with a minimum viscosity grade of 15W40 is used, then the oil and filters must be changed every 250 hours after the initial 750 hour oil and filter change.


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


Escaping hydraulic oil under pressure can have sufficient force to penetrate the skin, causing serious injury. If injured by escaping fluid, see a doctor at once. Serious infection or reaction can develop if proper medical treatment is not administered immediately.

Engine oil change

NOTE: Change the engine oil when the engine is warm. Refer to the engine owner's manual for the correct replacement oil and filter change recommendations.


The engine drain plug is near to the muffler. To prevent burns, the engine should be shut off and allowed to cool slightly so the engine is still warm but the adjacent surfaces and oil are not.

  1. Park on a level surface. Engage park brake.
  2. Clean the dirt and debris from the area around the oil fill cap.
  3. Remove the cap/dipstick.
  4. Find the drain hose at the right rear of the engine. Place a sufficiently sized container under the end of the drain hose and remove the oil drain plug.
    Engine oil change
  5. Let the used oil fully drain from the engine.
  6. Replace and tighten the drain hose plug.
  7. Fill the engine with new oil to the bottom of the fill tube threads. Check the level with the dipstick.
  8. Replace and tighten the oil fill cap when the oil level is FULL.
  9. Refer to the Service Journal for oil checking and changing intervals and change recommendations.

Wheel and Deck Zerks

Use only good quality bearing grease. Grease from well-known brand names (petrochemical companies, etc.) usually maintains a good quality.
Front Wheel Mount
Lubricate 3-4 strokes with a grease gun on each set of wheel mounts.

Front Wheel Bearings
Lubricate 3-4 strokes with a grease gun on each set of wheel bearings.
Front Wheel Bearings Lubrication

Deck Spindles
Lower the cutting deck completely.

If a grease gun without rubber hose is used, the foot plate must be removed to access the center spindle.

Lubricate with a grease gun, 2-3 strokes per spindle.
Deck Spindles Lubrication

Oil and Filters Change

The hydraulic oil and filters must be replaced every 250 to 750 hours or once per year, depending on the type of oil used. See Qualified Hydraulic Oils in the Lubrication section for a list of approved oils or refer to the transmission manufacturers service manual.

Due to the risk of impurities entering the system, all transmission work should be performed by an authorized service workshop.

The following procedure is performed with the transmissions installed in the mower and the mower on level ground. Apply the pump release valve for each transmission and set the park brake.

  1. Thoroughly clean the unit free of grass and other debris. Clean any loose debris from around the perimeter of the filter.
  2. Remove breather / dipstick.
  3. Place an oil drain pan (12" or more diameter and 8 qt. capacity is optimal) beneath the oil filter.
  4. Using a socket and ratchet, remove filter plug and O-ring assembly.
  5. Using a strong magnet or pair of needle nose pliers, remove the oil filter.
  6. Install the new filter.
  7. Install filter plug and O-ring assembly. Torque filter plug to 115–135 in/lbs.
  8. Repeat steps on the opposite side.
  9. 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.
    Oil and Filters Change
  10. Fill transmission with Paker HT-1000 transmission oil or other approved hydraulic fluid.
  11. The cold fluid level should touch the bottom of the breather/dipstick.
  12. Install breather / dipstick and torque to 18–30 in./lbs.

Transmission Purging
Purge procedures must be implemented if the hydrostatic system has been opened for maintenance or when more oil has been added to the system. Due to the effects air has on efficiency in hydrostatic drive applications, it is critical to purge the system. Resulting symptoms of air in hydrostatic systems may be:

  • Noisy operation.
  • Lack of power or drive after short term operation.
  • High operation temperature and excessive expansion of oil.
  • Shortened component life.

Before starting, make sure the oil tank is at the proper oil level. If not, fill to the specifications outlined above.

Perform the procedure first with the vehicle drive wheels off the ground, then repeated under normal operating conditions.

See Moving Machine By Hand in the Operation section for bypass linkage adjustments.

  1. Disengage the brake if activated.
  2. With the bypass linkage open and the engine running at fast idle, slowly move the directional control in both forward and reverse directions (5 or 6 times). As air is purged from the unit, the oil level will drop.
  3. With the bypass linkage closed and the engine running, slowly move the directional control in both forward and reverse directions (5 to 6 times). Check the oil level and add oil as required after stopping the engine.
  4. It may be necessary to repeat Steps 2 and 3 until all the air is completely purged from the system. When the hydraulic drive operates at normal noise levels and moves smoothly forward and reverse at normal speeds, the hydraulic drive is considered purged.
  5. After the vehicle has been used two times, the oil level must be checked while the oil is cold and adjusted accordingly.

STORAGE

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 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 a stabilizer has been added.


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 serious 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:

  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 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.
