Operation

V Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use accessories and attachments approved by the manufacturer.

V Never leave a running machine unattended. Park the machine on level ground. Place park brake lever in the brake engaged position, place the PTO lever in the

“OFF” position, lower attachment, remove ignition switch key before leaving operator’s seat for any reason including unclogging the chute.

V Do not change the engine governor setting or overspeed the engine.

V Always remain seated while operating machine.

V Always keep safety shields and covers in place, except for servicing.

V Always maintain a safe distance from people and pets when mowing. Always stop machine if someone enters the area.

V Always operate machine in daylight or with adequate working lights.

V Follow daily and weekly checklists, making sure hoses are tightly secured and bolts are tightened.

V Always observe traffic laws while driving machine from one location to another. Watch for traffic when operating near or crossing roadways.

V Always be alert for hazards such as rocks, metal objects and other debris which may be thrown or entangled by mower blades. Watch out for holes or deep depressions.

V Inspect area to be mowed for hazards such as rocks, metal objects and other debris which may be thrown or entangled by mower blades. Remove these objects before mowing.

V Always inspect machine for damage after striking a foreign object. If damage is found, repair machine immediately. Be sure to stop on level ground, place park brake lever in the brake engaged position, place the PTO lever in the “OFF” position, lower attachment, remove ignition switch key before leaving operator’s seat to inspect damage.

V Never engage the PTO Control Lever unless the PTO shaft is securely connected to a power driven attachment.

V Always wear adequate ear protection, such as earplugs, when operating this equipment as prolonged exposure to uncomfortable or loud noises can cause impairment or loss of hearing. Do not wear radios or music headphones while operating the machinery. Safe operation requires your full attention.

V Do not operate the equipment while wearing sandals, tennis shoes, sneakers, shorts or any type of loose fitting clothing. Long hair, loose clothing or jewelry may get tangled in moving parts. Always wear long pants, safety glasses, ear protection and safety shoes when operating this machine.

V Always be aware of what is behind the machine before backing up. Do not mow in reverse unless absolutely necessary. Always look down and behind before and while backing up.

V Never push down suddenly on brake pedal while the machine is in forward motion because machine may tip forward causing loss of control.

V Never push down suddenly on the HST reverse pedal while the machine is in forward motion because machine may tip forward causing loss of control.

V Never drive the tractor at high speeds without a frontend attachment mounted to the tool bars. Keep the attachment as low to the ground as possible, mower decks should rest on the gauge wheels.

V Never operate a poorly maintained machine.

V Never attempt high speed maneuvering, especially in crowded or congested areas.

V Never allow persons to operate this machine without proper instruction or allow children to operate machine. Allow only responsible adults who are familiar with these instructions to operate this machine.

V Never put hands or feet under any part of the machine while it is running.

V Never carry passengers.

V Never direct discharged material toward anyone.

Avoid discharging material against a wall or obstruction. Material may ricochet back toward the operator.

Always disengage the blades and wait for them to stop before crossing gravel drives, walks or roads.

V Always keep clear of the mower blades and attachments during their operation.

V Turn off blades when not mowing.

V Slow down before turning.

V Stop the engine before removing the grass catcher or unclogging the discharge chute. Never clear the discharge chute with the engine running. Turn off the engine and be sure the blades have stopped before cleaning. Use a stick to clear a plugged discharge area.

Never use your hand!

V Do not operate the machine while under the influence of alcohol or drugs.

V Exercise caution when loading or unloading the machine onto a trailer or truck.

V Always wear safety goggles or safety glasses with side shields when operating the tractor.

V Data indicates that operators, age 60 years and above, are involved in a large percentage of riding mowerrelated injuries. These operators should evaluate their ability to operate the mower safely enough to protect themselves and others from serious injury.

V Follow the manufacturer’s recommendation for wheel weights or rear counter-balance weights.

V If any attachment or additional weight is mounted on the front of the unit, any rapid movement of the HST

109627_0910 3-1

pedals in either direction could result in a reaction of the tractor that can cause serious injury.

V When desconnection on attachment that uses the tractor PTO output shaft to power the attachment, the powered shaft of device must also be disconnected from the tractor PTO output shaft. Never leave an unsupported

PTO device attached to the tractor PTO output shaft, if it is not completely and properly assembled to the attachment on which it’s use is intended.

V Clean flammable material from machine. Prevent fires by keeping engine compartment, exhaust area, battery, fuel line, fuel tank and operator’s station clean of accumulated trash, grass clippings, and other debris. Always clean up spilled fuel and oil.

Using a ramp

V Use extreme caution when loading and unloading a unit onto a truck or trailer with a ramp.

V Use only a single, full width ramp; do not use individual ramps for each side of the unit. Having a full width ramp provides a surface for the tractor frame to contact if the unit starts to tip backwards. It also reduces the risk of a wheel going off and the machine tipping over.

V Do not exceed a 15 degree angle between the ramp and the ground or between the ramp and the trailer or truck.

V When on a ramp avoid sudden acceleration.

Slope Operation

Slopes are a major factor in loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution. REMINDER: Only operate on slopes of 15 degrees or less.

V Use extreme caution when operating on slopes.

• Be extremely careful changing directions on a slope.

Slow down.

• Do not operate where the machine could slip or tip.

• Turn slowly

• Turn on the most level part of the slope

• While driving on slopes, always run in AWD (All wheel drive) locked position.

• Never make sudden changes in speed or direction.

• If it becomes necessary to turn downhill, turn slowly and gradually, if possible.

V Watch for holes, ruts, bumps, rocks or other hidden objects. Uneven terrain could overturn the machine.

Tall grass can hide obstacles.

V Remove obstacles such as rocks, tree limbs, etc.

V Keep all movement on slopes slow and gradual. Do not make sudden changes in speed or direction.

V Avoid starting and stopping on a slope. If tires lose traction, disengage the blades and proceed slowly straight down the slope.

V Mow a safe distance (minimum of 10 feet) away from drop-offs, retaining walls, drainage ditches, embankments, water, and other types of hazards to avoid a wheel dropping over the edge or to avoid the ground from breaking away. This will reduce the risk of the machine suddenly rolling over causing serious injury or death.

3-2

V Use a walk behind, push mower or hand-held trimmer on slopes and near drop-offs, retaining walls, drainage ditches, embankments and water to avoid machine rollover and serious injury or death.

V Do not mow on wet grass. Reduced traction could cause sliding and loss of steering control.

V If the mower’s tires lose traction when operating on slopes, disengage the blades, engage the park brake, turn the engine off and get help.

V Never make sudden starts, stops, turns, or reverse direction, especially when maneuvering on slopes.

The steering is designed for sensitive response. Rapid movement of the steering wheel or HST foot pedals in either direction could result in a reaction of the tractor that can cause serious injury.

V Never stop suddenly while going down slopes. This action may result in a reaction of the tractor that can cause serious physical injury.

V The Hustler mower is capable of operating horizontally

(traverse) on moderately steep slopes. When operating on slopes up to 15 degrees, be aware of any conditions that may cause the tractor drive tires to lose traction resulting in a possible loss of control of the machine.

An operator should not operate on a slope until he is thoroughly familiar with the equipment.

Do not operate on slopes greater than 15 degrees.

Refer to Slope Guide, page 2-7, when determining the degree of slope to be mowed.

It is strongly recommended that the operator drive the machine off of the slope, using extreme caution, if any sign of loss of traction is detected. Wait until the condition that caused the problem is resolved before attempting to operate on the slope again.

Terrain conditions can affect traction resulting in possible loss of control of the machine. Some of the conditions to be aware of are:

1. Wet terrain

2. Depressions in the ground; i.e. holes, ruts, washouts

3. Mounds of dirt

4. Soil type; i.e. sand, loose dirt, gravel, clay

5. Grass type, density, and height

6. Extremely dry conditions of grass

7. Tire pressure

The attachments mounted to the tractor will also affect the way it handles on a slope. Be aware that each attachment’s characteristics vary.

Do not tow on slopes. The weight of the towed equipment may cause loss of traction and loss of steering control.

Another consideration to safe mowing on slopes is to be aware of what is located at the bottom of the slope.

Extreme caution should be used when there is a hazard located at the bottom of the slope. Some examples are:

1. Water; i.e. lake, river

2. Cliffs, retaining walls

3. Roads, highways

4. Buildings

5. Rocks

These are just a few examples of situations when caution must be used when operating on a slope. There are

109627_0910

many other possibilities too numerous to mention.

Just remember to always exercise extreme caution when operating on any slope.

V The ROPS will minimize chance of injury or death from rollover. Seat belt must be fastened while operating a machine equipped with ROPS in the raised and secured position. Both retaining pins and hair

pins must be installed. Failure to use seat belt will result in serious injury in the event of a roll over.

Children

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.

V Never leave machine unattended with ignition key in switch, especially with children present.

V Children or bystanders may be injured if they move or attempt to operate the tractor while it is unattended.

Always disengage PTO lever, engage park brake, stop tractor engine, and remove ignition key when leaving operator’s seat.

V Keep children out of the mowing area and under the watchful care of a responsible adult other than the operator.

V Be alert and turn the machine off if children enter the area.

V Before and while backing, look behind and down for small children.

V Never carry children, even with the blades off. They may fall off and be seriously injured or interfere with safe machine operation. Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the machine.

V Never allow children to operate the machine.

Stopping the engine should be done according to the following procedures;

1. Pull the throttle lever fully rearward to the low idle position.

2. Release the HST foot pedals.

3. Engage the parking brake.

4. Place the transmission selector and lift control levers in the “N” position.

5. Turn the key start switch to the “OFF” position.

6.

Remove the key.

IMPORTANT: Failure to turn the key start switch to the

“OFF" position, after the engine stops, will allow the warning lights to remain on, causing the battery to discharge.

IMPORTANT: Do not stop the engine immediately after hard or extended operation. Keep the engine running at slow idle for about 2 minutes to allow engine to cool down.

Operating the hydrostatic transmission and

PTO

Hydrostatic transmission

The hydrostatic transmission is controlled by the HST foot pedals, cruise control switch, and transmission selector lever.

Figure 3-5, Figure 3-8 & Figure 3-9

When operating the transmission selector lever, place the

HST foot pedals in the neutral position. If it is difficult to engage, slightly depress the Forward or Reverse foot pedal for smooth engagement.

Never engage or disengage the transmission selector lever when the unit is in motion.

With the transmission selector lever in “H” range (Figure 3-

10), ground speed can be varied from zero to maximum by depressing the forward or reverse travel pedal. In “L” range, speeds are about 60% of “H” range. Maximum speeds in

reverse are about a 65% of maximum forward speeds.

To stop the unit, release the pedal gradually (except on an emergency). When released, the pedal returns to the Neutral position automatically, stopping the unit. Sudden release can result in an abrupt, and possibly dangerous stop.

For prolonged operation at a fixed forward speed, use the forward travel pedal to attain the desired speed, then move the cruise control switch to the “ON” position. Speed will remain at the set value when the pedal is released.

To cancel the speed setting or stop, push the switch to the

“OFF” position or firmly depress the master brake pedal.

Automatic or Locked All Wheel Drive (AWD)

The transmission selector lever is used to select Automatic

Four-Wheel Drive or Locked Four-Wheel Drive.

When the Transmission Selector lever is located in the inside slot, the tractor will run in Automatic AWD mode.

Figure 3-9

When the lever is placed in the outer slot, the mower will run in Locked AWD mode and low range. Figure 3-10

When in motion, always bring the unit to a complete stop before moving the transmission selector lever.

Automatic All Wheel Drive (AWD) means that the fourwheel drive line is engaged automatically when the front wheels start to slip, but, in normal operation, reverts to 2WD, this provides sharp and smooth turns without damaging turf.

Locked Four-Wheel Drive should be used when additional traction is required while operating in loose soil, wet, slippery conditions or slopes.

NOTE: The steering (rear) axle is not powered in reverse when tractor is operating in Automatic AWD.

Power take-off operation

The power take-off (PTO) transfers engine power directly to the PTO equipment.

PTO is controlled through the PTO lever. To engage the

PTO, push the lever forward. To disengage the PTO, pull the lever rearward. Figure 3-11

WARNING: To avoid personal injury, keep children and others away when operating PTO equipment.

NOTE: The PTO lever must be placed in the disengaged position to start the tractor.

Operating the differential lock

Do not engage the differential lock when ground speed is above 5 mph (8 kmh). Figure 3-7

The differential lock is engaged by depressing the differential lock pedal. Depressing the pedal locks both differential gears together, preventing one wheel from rotating independently of the other. The lock should be used to obtain additional traction from the opposite wheel whenever one wheel begins to slip in wet or loose soil.

NOTE: The differential lock pedal only locks the front axle when applied. The rear axle is not lockable.

WARNING: Do not engage the differential lock when turning the unit. If the lock is engage when turning, a loss of steering control will result.

To operate the differential lock depress and hold down the pedal until the lock is positively engaged. It is best to engage the differential lock while the wheels are turning slowly to minimize shock loads to the drive line. If a wheel spins at high speed, as on ice, reduce engine speed to idle before

engaging the lock, or damage may occur. The differential lock is released when the pedal releases as the loads equalizes on both drive wheels.

NOTE: In some instances the lock may remain engaged after the pedal is released. This may occur if one front wheel tends to turn at a faster speed than the other. Should this happen, the lock may be disengaged by decreasing the drawbar pull by raising or disengaging the implement so that neither wheel tends to slip.

Operating the hydraulic lift system

The hydraulic lift system provides hydraulic power for raising front mounted equipment whenever the engine is running.

To raise the front mounted equipment, pull the lift control lever rearward and hold it until the desired equipment height is reached. Figure 3-11

To lower the equipment, push the lever forward. When pushed all the way forward, the lever will remain in a lowered float detent position.

IMPORTANT: Always set the lift control lever in the float detent position when mowing.

WARNING: Make sure the area is clear of people before raising or lowering equipment.

WARNING: Always lower the hydraulic lift and equipment before stopping the unit.

3-10

Weight transfer valve

The weight transfer valve is used to transfer the front attachment weight to the tractor unit to reduce equipment weight on turf and prevent damage and improve front drive wheel traction. Figure 3-11

The weight transfer valve should be used according to the following procedures;

1. With the engine running, push the hydraulic lift lever forward to the floating position.

2. Turn the adjusting knob clockwise until the mower or other equipment lifts off the ground.

3. Turn the adjusting knob counter-clockwise slowly until the mower deck front gauge wheels or other equipment just touches the ground, then turn the knob counterclockwise 1/4 turn more.

4. Operate the unit over uneven terrain at desired travel speed and observe the mower deck’s front gauge wheels. If the wheels or equipment do not follow ground contour, the operation will be affected.

5. To correct this condition, turn the knob 1/4 turn clockwise at a time until the mower deck’s front gauge wheels follow the ground contour.

Auxiliary hydraulic valve kit (optional)

An Auxiliary Hydraulic Valve kit is available from your

Hustler Dealer, as an option. When using the auxiliary valve,

109627_0910

the lift control lever must remain in neutral. Figure 3-17 and

Figure 3-18

Auxiliary control valve levers

WARNING: Never attempt to connect or disconnect the couplers with the hydraulics engaged and the system oil under pressure.

Rear counter-balance weights

WARNING: Improper operation on slopes can cause injury. Install rear counter-balance weights, when the attachment is installed, to increase stability. Use extreme care when operating on slopes.

Rear counter-balance weights are required to improve stability, steering and traction. They also reduce tire lift off when attachments are raised, operated on slopes or during an abrupt stop. Refer to Figure 3-19 for weight attachment.

Refer to the attachment’s owner’s manual for the proper weight amount and weight part number.

ROPS

(Roll Over Protective Structure)

A Roll Over Protective Structure (ROPS) and seat belt are standard equipment. Do not remove the ROPS and seat belt.

ROPS when used with seat belt is effective in reducing injuries during unit overturn accidents. Overturning the unit without ROPS can result in serious injury or death.

NOTE: Inspect the ROPS after the first 20 hours of operation. Following the initial inspection, check the ROPS after every 500 hours of operation or every six months, whichever comes first. Figure 3-20

1. Check the torque of the ROPS mounting bolts. Tighten the bolts to the correct torque of 72 ft.-lbs. (97 Nm) if necessary. Figure 3-21

2. Inspect the operator’s seat and the mounting parts for the seat belt. Tighten the bolts to the correct torque of

72 ft.-lbs. (50.0 Nm) if necessary and replace parts that show wear or damage.

The two-post ROPS can be pivoted down by removing the right and left retaining rings and pulling out on the pins so that the machine can operate under low hanging tree limbs or other obstructions. (Figure 3-22) Do not wear the seat belt

WARNING: Do not operate the mower with the

ROPS folded (lowered position) as a standard operating mode. A folded ROPS does not provide rollover protection.

WARNING: Always wear your seat belt unless the tractor is not equipped with a ROPS or safety cab or if the ROPS is folded down. In this case, the seat belt should never be worn.

WARNING: To minimize chance of injury or death from rollover: keep ROPS in the raised and locked position and use the seat belt.

Never operate machine on a slope with the ROPS folded down (lowered position).

There is no roll over protection when the ROPS is in the lowered position.

Lower the ROPS only when absolutely necessary.

Drive slowly and carefully. Raise the ROPS as soon as clearance permits. Read and follow slope operation instructions and warnings.

Do not wear seat belt when the ROPS is in the lowered position.

WARNING: Always pull from the tractor hitch. Do not attach chains or ropes to the ROPS for pulling purposes,as the machine can tip backwards.

Always fasten seat belt during operation of the machine with ROPS in “raised/up” position. Figure 3-20

Inspect the area to be mowed for proper overhead clearance

(tree limbs, guy wires, doorways, etc)

Do not contact any overhead object with the ROPS.

Inspect the seat belt system (all seat, seat belt parts, seat pan and seat pan latch) daily prior to mowing for signs of any damage. These parts should be replaced if any parts indicate signs of:

1. cuts

2. fraying

3. extreme or unusual wear

4. significant discoloration due to UV exposure

5. dirt or stiffness

6. abrasion to the seat belt webbing

7. damage to the buckle, latch plate or hardware.

8. or any other problem

If the seat belt is to be cleaned, use soap and water. Do not use carbon tetrachloride, naphtha, etc., as these will weaken the webbing. For the same reason, do not bleach or dye the webbing. Replace seat belt if worn or damaged.

Possible damage to the ROPS

If the unit has rolled over or the ROPS has been in some other type of accident (such as hitting an overhead object during transport), the ROPS must be replaced to retain the best protection.

Following an accident, check the ROPS, the operator’s seat, and the seat belt and seat belt mountings for possible damage,

Before operating the machine, replace all damaged parts.

IMPORTANT: Do not attempt to weld or straighten the

ROPS.

WARNING: If the ROPS or cab is removed or replaced, make sure that the proper hardware is used and the recommended torque values are applied to the attaching bolts.

WARNING: The ROPS structure’s protective capability may be impaired by structural dam-

3-12 109627_0910

age, overturn or alteration. If any of these conditions

occur, this structure must be replaced.

WARNING: Do not remove or alter any of the

ROPS parts. Failure to adhere to these instructions could result in severe injury or death. Do not attempt to weld or straighten ROPS. Failure to adhere to these instructions could result in severe injury or death..

Retaining pin

ROPS uneven terrain. To prevent personal injury, observe the following precautions when driving the unit.

V Watch where you are going - especially at row ends, on roads, and around the trees.

V Reduce speed before turning or applying brakes.

V Avoid sudden starts and stops on slopes.

V Be careful when changing direction on slopes.

V Stay alert for holes, rocks, roots and other hidden hazards in the terrain. Keep away from drop-offs.

V Do not park on slopes.

V Avoid quick stops especially when an attachment is not installed or raised. Quick stops will cause upsets.

DANGER: Use extreme care when operating on slopes. Inexperienced operators may have a tendency to oversteer and lose control. Slow-moving practice maneuvers are recommended to become familiar with these characteristics before attempting normal speed operation.

WARNING: Sharp depressions or raised obstacles

(such as gutters or curbs) should not be directly approached at high speed in an attempt to “jump” them as the operator could be thrown from the equipment. Approach at a slow speed and angle one drive wheel at the obstruction. Continue at an angle until the wheel clears and then pivot the opposite wheel around.

Tractor performance is maximum when the throttle is set at full rpm. This gives maximum power to the drive wheels and deck when needed. Use the HST pedals to control ground speed rather than engine rpm.

Figure 3-22

MAINTENANCE & ADJUSTMENTS

Safe Servicing Practices

IMPORTANT: This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.

Service

V Unless specifically required, DO NOT have engine running when servicing or making adjustments to tractor. Park the machine on level ground. Place park brake lever in the brake engaged position, place the

PTO lever in the “OFF” position, lower attachment, remove ignition switch key and disconnect negative battery cable before doing any maintenance. Wait for all movement to stop before adjusting, cleaning or repairing. Repairs or maintenance requiring engine power should be performed by trained maintenance personnel only. To prevent carbon monoxide poisoning, be sure proper ventilation is available when engine must be operated in an enclosed area. Read and observe safety warnings in front of manual.

V Before working on or under the deck, make certain engine cannot be accidentally started. Shut engine off, remove ignition switch key, engage park brake and disconnect negative battery cable for maximum safety.

Repairs or maintenance requiring engine power should be performed by trained maintenance personnel only.

V Except when changing or checking belt, always keep safety shields and covers in place.

V Use a stick or similar instrument to clean under the mower making sure that no part of the body, especially arms and hands are under mower.

V Keep your machine clean and remove any deposits of trash and clippings, which can cause engine fires and cooling system overheating as well as excessive belt wear. Clean up oil or fuel spillage. Allow machine to cool before storing.

V Clean flammable material from machine. Prevent fires by keeping the top of the deck, engine compartment, radiator screen, front screen, exhaust area, battery, hydraulic lines, fuel line, fuel tank and operator’s station clean of accumulated trash, grass clippings, and other debris. Always clean up spilled fuel and oil.

V Always wear adequate eye protection when servicing the hydraulic system, cooling system, battery or when grinding mower blades and removing accumulated debris.

V Use extra caution when handling diesel fuel. It is flammable and vapors are explosive.

V Never attempt to start engine when there is a strong odor of diesel fumes present. Locate and correct cause.

V Never remove fuel cap or refuel tractor while engine is running; never refuel near an open flame or near devices which can create a spark. Refuel outdoors.

Never refuel or drain the fuel from the machine indoors.

V Never run the engine in an enclosed area unless exhaust is vented to the outside. Exhaust gases contain carbon monoxide which is odorless and deadly poison.

V Never attempt to make any adjustments or repairs to the tractor drive system, mower deck or any attachment while the tractor engine is running or PTO is engaged.

Repairs or maintenance requiring engine power should be performed by trained maintenance personnel only.

V Never work under the machine or attachment unless it is safely supported with jack stands. Make certain machine is secure when it is raised and placed on the jack stands. The jack stands should not allow the machine to move when the engine is running and the drive wheels are rotating. Use only certified jack

stands. Use only appropriate jack stands, with a minimum weight rating of 3500 pounds to block the unit up. Use in pairs only. Follow the instructions supplied with the vehicle stands.

V Do not touch hot parts of machine.

V Keep nuts and bolts tight, especially the blade attachment bolts. Keep equipment in good working condition.

V Never tamper with safety devices. Check their proper operation daily.

V Stop the engine before removing the grass catcher or unclogging the discharge chute. Never clear the discharge chute with the engine running. Turn off the engine and be sure the blades have stopped before cleaning. Use a stick to clear a plugged discharge area.

Never use your hand!

V Grass collection system components are subject to wear, damage and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check components and replace with manufacturer’s recommended parts, when necessary.

V Exercise caution when working under the deck as the mower blades are extremely sharp. Wrap the blade(s) or wear gloves and use extra caution when servicing them. Take care as the rotation of one blade can cause the other blades to rotate.

V Use only genuine Hustler replacement parts to ensure that original standards are maintained

Introduction

Regular maintenance is the best prevention for costly downtime or expensive, premature repair. The following pages contain suggested maintenance information and schedules which the operator should follow on a routine basis.

For more detailed information order the correct parts manual for your unit. Refer to the Product Literature section of this manual.

Remain alert for unusual noises, they could be signaling a problem. Visually inspect the machine for any abnormal wear or damage. A good time to detect potential problems is while performing scheduled maintenance service. Correcting the problem as quickly as possible is the best insurance.

Clear away heavy build-up of grease, oil and dirt, especially in the engine and under the seat platform areas; minute dust

109627_0910 4-1

particle are abrasive to close-tolerance engine and hydraulic assemblies.

Daily inspect mower for grass clippings and wire and string tangles. The underside of the mower deck will collect a build-up of grass clippings and dirt, especially when grass is wet or has high moisture content. This build-up will harden, restricting blade and air movement and will probably show a poorer quality of cutting. Therefore it should be removed routinely.

To do this it will be necessary to raise and block the deck, using jack stands or blocks, in the full up position and scrape the build-up from underneath. Refer to the deck owner’s manual for more detailed information.

Some repairs require the assistance of a trained service mechanic and should not be attempted by unskilled personnel. Consult your Hustler service center when assistance is needed.

WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

WARNING: Charge batteries in an open well ventilated area, away from spark and flames. Unplug charger before connecting or disconnecting from the battery. Wear protective clothing and use insulated tools.

WARNING: Avoid skin and clothing contact with battery acid.

Always wear eye protection when checking the battery, acid can cause serious injury to skin and eyes.

If contact occurs, flush area with clean water and call physician immediately. Acid will also damage clothing.

Do not drink the battery electrolyte.

Do not allow open flame near the battery when charging.

Hydrogen gas forms inside the battery. This gas is both toxic and flammable and may cause an explosion if exposed to flame. Always remove the negative ground first and replace it last.

Do not overfill battery.

Electrolyte may overflow and damage paint, wiring or structure. When cleaning the battery, use soap and water. Be careful not to get soap and water into the battery. Clean the battery terminals with a solution of four parts water and one part baking soda when they become corroded.

WARNING: Shorts caused by battery terminals or metal tools touching metal tractor components can cause sparks. Sparks can cause a battery gas explosion which will result in personal injury.

Prevent the battery terminals from touching any metal tractor parts when removing or installing the battery.

Do not allow metal tools to short between the battery terminals and metal tractor parts.

WARNING: Incorrect battery cable routing could cause damage to the tractor and battery cables. This can cause sparks which can cause a battery gas explosion which will result in personal injury.

Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable.

Always connect the positive (red) battery cable before connecting the negative (black) cable.

Alternator

The 3500/3700 40-amp alternator is belt-driven from the engine crankshaft pulley. It is important that belt slippage does not occur, or the charging system will be affected. Figure

4-3

To adjust the belt, see the instructions given under the Fan

Belt section located elsewhere in this manual.

Other than belt adjustment, the only alternator maintenance required is to periodically inspect the terminals to ensure they are clean and tight. The alternator cooling fins should also be cleaned periodically.

When working on or checking the alternator, adhere to following precautions or alternator damage may occur:

• Do not, under any circumstances, short the field terminal of the alternator to ground.

• Do not disconnect the alternator output lead or battery cables while the alternator is operating.

• Do not remove the alternator from the tractor without first disconnecting the negative (-) battery cable.

When removing the battery, disconnect the negative

(-) cable first.

• To install a battery, make sure that the positive (+) cable is connected first and that the negative terminal is connected to ground. Reverse polarity will destroy the rectifier diodes in the alternator.

If the battery charge warning light illuminates, indicating that the alternator is not charging the battery, check the fan belt and the wiring connections. If these items are in satisfactory condition and the warning light continues to indicate no charge, consult your Hustler Dealer.

Fuel system

DANGER: To avoid personal injury or property damage, use extreme care in handling diesel fuel.

Diesel fuel is extremely flammable and the vapors are explosive.

DANGER: Observe usual fuel handling precautions:

Do not smoke while refueling or anywhere near fuel. Extinguish all cigarettes, cigars, pipes and other sources of ignition.

Do not remove fuel cap or fill tank with engine running or while engine is hot. Clean up any diesel fuel spills immediately.

Always tighten the fuel cap securely.

Allow engine to cool before storing machine inside a building.

Keep fuel away from open flame or spark and store machine away from open flame or spark or pilot light such as on a water heater or other appliances.

Use extreme care when handling diesel fuel. It is extremely flammable and vapors are explosive. A fire or explosion from diesel fuel can burn you and others and can damage property.

Never refuel or drain the diesel fuel from the machine indoors.

Never attempt to start engine when there is a strong odor of diesel fuel fumes present. Locate and correct cause.

Store diesel fuel in an approved container and keep it out of the reach of children.

Do not fill diesel fuel containers inside a vehicle or on a truck or trailer bed with interior carpets or plastic truck bed liners. Always place diesel fuel containers on the ground away from your vehicle before filling.

When practical, remove diesel fuel-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground. If this is not possible, then refuel such equipment on the truck or trailer using a portable container and not a fuel dispenser nozzle. If a fuel dispenser nozzle must be used, 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 lock-open device.

Never use diesel fuel or gasoline for cleaning parts.

Read and observe safety precautions elsewhere in this manual.

WARNING: Diesel fuel is harmful or fatal if swallowed.

Long-term exposure to vapors can cause serious injury and illness.

Avoid prolonged breathing of vapors.

Keep face away from nozzle and fuel tank or diesel fuel container opening.

Keep diesel fuel away from eyes and skin.

If diesel fuel is spilled on clothing, change clothing immediately.

WARNING: Under no circumstances should gasoline, alcohol, or gasohol be added to diesel fuel.

These combinations can create an increased fire or explosive hazard.

WARNING: Fuel System Under Pressure! Fuel in the injection system is under high pressure and can penetrate the skin. Unqualified persons should not remove or attempt to adjust a pump injector, nozzle or any part of the fuel injection system.

Do not use your hand to check for leaks. Use a piece of cardboard or paper to search for leaks.

If any fluid is injected into the skin, obtain medical attention immediately or gangrene may result.

Failure to follow these instructions can result in serious injury.

Check the fuel line periodically as it is subject to wear and aging, fuel may leak onto the engine which could cause a fire.

IMPORTANT: Do not fill tank to capacity. Allow room for expansion.

IMPORTANT: If the original fuel tank cap is lost, always replace it with a Hustler approved cap. A “will fit cap” may not be safe.

Diesel fuel

• Use clean, quality No. 1-D or No. 2-D fuel

• Use No. 1-D fuel if the ambient temperature is expected to be lower than 39 degrees F (4 degrees C) or if the tractor is to be used at an altitude exceeding

5000 ft. (1524 m).

• Use diesel fuel with a pour point of at least 10°F

(12°C) below the expected ambient temperature to prevent fuel flow problems in cold weather.

• Keep dirt from entering the fuel tank.

• Sulfur content of the fuel should be no more than

0.05%.

• Sediment and water content should not exceed

0.05%.

• Minimum cetane number is 40. Low temperature or high altitude operation may require use of fuel with a higher Cetane number.

• Use properly mixed winter fuel when temperatures are extremely cold. In most areas, diesel fuel is properly blended for summer and winter grades as ambient temperatures change. In winter, use winter grade diesel fuel only. Otherwise, the fuel may cloud and block the fuel system.

Refueling the Tractor

The fuel tank filler cap is located at the left side of the tractor hood. Before removing the cap, wipe all dust and dirt from around the cap to prevent debris from falling into the tank while filling. Figure 4-10

Use an approved fuel container and check the inside of the container periodically for cleanliness. Fuel tank capacity is

13.33 gallons (50.5L).

NOTE: The fuel cap is a vented-type. Use only an approved Hustler replacement cap to prevent fuel systemrelated problems.

If there is no filter on the storage tank or fuel container, filter the fuel through a 100-mesh or finer screen when filling the mower fuel tank. Keep the mower tank as full as possible

(without filling to capacity) to minimize condensation.

NOTE: It is a good practice to fill the fuel tank at the end of each day, as this will reduce overnight condensation.

7. Open the fuel shutoff valve (the handle should be pointing to the “O” position), so fuel will flow to the filter. Figure 4-12

8. Bleed the fuel filter and injection pump as described below in Bleeding the Fuel System.

Bleeding the fuel system

IMPORTANT:

The 3500/3700 fuel system is designed to bleed automatically.

1. When the fuel tank is empty

Fill until the fuel level of the tank is at least half full, then wait about one minute for air to dissipate.

109627_0910 4-7

Figure 4-12

2. When the fuel filter has been replaced:

After replacing the filter, open the fuel shutoff valve.

Air will dissipate for about one minute

NOTE: Fuel tank fuel level must be half full or more for auto bleed system to function correctly.

NOTE: The 3500/3700 is an auto bleeding system. No manual bleeding procedures needed.

Engine oil and filter

Checking the Engine Oil Level

Check engine oil daily. Tractor must be setting level and the engine stopped for a period of time when checking oil level. Refer to engine manual and maintenance schedule for oil recommendation and capacities.

Change the engine oil and filter every 100 hours or annually, whichever comes first.

NOTE: If tractor is being operated in extremely dirty conditions, then it is recommended oil be changed more frequently. If the engine is operated for extended periods of time at maximum rated power and speed or under other types of continuous, severe operating conditions the oil and filter should be changed at 70 hours intervals following the initial oil change.

Refer to Figure 4-13 for the engine oil filter and dipstick location.

Refer to Figure 4-14 for the engine oil fill location.

Refer to Figure 4-15 for the engine oil drain location.

Changing the oil

1. Before adding engine oil, place the unit on a level surface, then remove the dipstick to provide crankcase ventilation.

2. Add oil at the oil fill shown. Figure 4-14

NOTE: When changing the engine oil, add the exact amount specified in the engine owner’s manual.

NOTE: Use CD grade or better by API classification engine oil.

3. Wait about fifteen minutes until the oil gets down to the oil pan. Then check the oil level with a dipstick. A

certain period of time is required before the engine oil completely flows down from the oil filler to the crankcase.

4. Check the oil level, accounting for the higher oil level due to the oil filter oil capacity.

Engine air filter

Perform engine air filter maintenance per the Service

Interval chart shown elsewhere in this manual.

A specially designed dry filter is standard equipment on these tractors and supplies clean combustion air to the engine.

Figure 4-16 Change the filter whenever the Air Cleaner

Restriction Warning Light comes on. Figure 3-1

These units are equipped with a safety filter. The filter element slides over the safety filter. NOTE: For maximum

4-8

Figure 4-15 engine protection and air cleaner service life, install a new inner safety element every third primary element change or after every 1000 hours of operation, whichever comes first.

NOTE: The safety filter does not require servicing unless it becomes contaminated with dirt or moisture.

Recommended service procedure

1. Release clamps and remove element. Clean the

2.

canister with a damp cloth.

Before installing a new element, inspect it by placing a bright light inside and rotate the element slowly, looking for any holes or tears in the paper.

Also check gaskets for cuts or tears. Do not attempt to use a damaged element which will allow abrasive

particles to enter the engine.

Install the new element and reinstall the dust cup.

Make sure it seals all the way around the air cleaner body, then tighten the clamps.

Check all fittings and clamps periodically for tightness and inspect hoses for holes or cracks.

Periodically check the intake hose for signs of ingested dust. Locate and repair the source of ingested dirt.

Never operate a machine without an air filter installed.

Overservicing

Overservicing occurs when an air filter element is removed for cleaning or replacement before it is necessary. Each time the filter is removed a small amount of dirt and dust could fall in the intake system. This accumulated dirt can cause a dusted engine. It only takes a few grams of ingested dirt over the normal service life of an engine to cause a dusted engine.

Do not clean element, replace with a new element only.

Cleaning used air filter elements, through improper cleaning procedures, can get dust on the inside of the filter causing dirt ingestion and engine failure.

109627_0910

It is important to note that whenever an air filter element is cleaned by any method, the person or company performing the cleaning assumes responsibility for the integrity of the filter from then on. The warranty for air filters expires upon cleaning or servicing in any manner because the condition of the filter after servicing is completely out of their control.

Therefore, on a dust ingested engine failure, there will be no warranty consideration if the air filter element has been cleaned or serviced in any manner.

A partially dirty air filter element works better than a new element. Therefore, a dirty filter element is not bad for the engine unless it is excessively restricting the air flow and engine performance is affected. The reason is simple. The media in the filter must be porous to allow air to pass through it. When dirty air passes through the filter, the dirt plugs some of the holes in the media and actually acts as part of the filter media. When the next round of dirt enters, the first dirt helps filter out even smaller particles making the filter more efficient at stopping dirt from entering the engine. This is referred to as barrier filtration.

Of course, at some point the filter media becomes too clogged to allow air to pass.

The mowing conditions will determine the frequency of air filter element changing.

Air filter coolant level only at the overflow reservoir (Figure 4-16). The cooling system is a closed type. Never open the radiator cap.

Doing so may induce air into the cooling system and may cause overheating. The coolant level should be between the low and full marks on the reservoir.

If the coolant recovery reservoir is low, refill system, with the proper coolant mixture, through the recovery reservoir. It is not necessary to remove the radiator cap to replenish the coolant.

Engine cooling is accomplished with a 50/50 mixture of clear water and Ethylene Glycol (anti-freeze). This mixture will provide freeze protection to -32° F (-34° C).

The radiator is equipped with a pressure cap and overflow reservoir.

DANGER: Never remove radiator cap or overflow reservoir cap when engine is hot. Pressurized hot steam and water may be released, causing serious burns or possible blindness.

The cooling system operates under pressure controlled by the radiator cap. It is dangerous to remove the cap while the system is hot. Always cover the cap with a thick cloth and turn it slowly counter-clockwise to the first stop. Allow all pressure to escape before removing the cap completely.

Be sure that the radiator fins are clear of chaff and dirt to allow free air movement.

Cooling system

The 3500/3700 engine must operate at the correct temperature to obtain maximum efficiency and service life. This is dependent on the cooling system.

Always fill the system with a 50/50 solution of permanent antifreeze and clear water.

Checking the coolant level

WARNING: Always wear eye protection when servicing the cooling system.

NOTE: Visually inspect the system daily prior to operating tractor. Be sure the engine is level. Open the hood, and check the coolant recovery reservoir located next to the battery. Check

the coolant level only when the system is cold. Check the

Figure 4-17

Draining and flushing the cooling system

NOTE: Drain and flush the radiator and engine block every

12 months. Refill with a 50/50 mixture of permanent antifreeze and clear water.

WARNING: Allow the engine and radiator to cool before draining and flushing the system.

To drain the cooling system:

1. Use a suitable receptacle to catch the used coolant.

Remove the radiator cap and open the drain valve to drain the radiator and engine block. Figure 4-18

2. After the coolant has drained, place a water hose in the radiator filler neck and run water through the system.

When water is flowing from the block drain valve, start the engine. When the water flowing from the drain valve, is free of discoloration and sediment, stop the engine and remove the hose. Allow all water to drain from the system through the drain valve.

3. Close the drain valve and slowly refill the system with a 50/50 solution of permanent antifreeze and clear water. Fill until the coolant level is approximately 1.5”-

2.0” (3.8cm-5cm) below the bottom of the filler neck.

Do not fill beyond this level.

4. Clean the radiator cap and cap seal and install the cap.

Figure 4-19

5. Fill the coolant recovery reservoir bringing the fluid level up until it is between the full and low marks on the reservoir.

6. Open the front screen and remove chaff, dust, or other foreign substances. The foreign substances can be dropped onto the ground through the rubber at the lower part. Figure 4-20

7. Pull out on the radiator screen and clean it. Figure 4-17

8. Run the engine until normal operating temperature is reached, then stop the engine. Recheck the coolant level when the engine is cold and add additional coolant as necessary.

IMPORTANT: Never run the engine when the cooling system is empty. Do not add cold water or cold antifreeze solution if the engine is hot.

Fan belt

NOTE: Check the condition of the fan belt after every 50 hours of operation. Check fan belt tension after every 200 hours of operation. Figure 4-21

A belt-driven fan located at the front of the engine draws air through the fins of the radiator to lower the temperature of the radiator coolant.

When 20-25 lbs. (9-11 kg) of thumb pressure is applied

4-10

Figure 4-20 midway between the water pump pulley and the alternator pulley, a correctly tightened belt will deflect .40”-.60”

(10mm-15mm).

If the fan belt is slipping, fan efficiency is lowered, resulting in the engine running too hot. If the belt is too tight, the life of the alternator bearing will be shortened. If the fan belt shows signs of cracking or fraying, install a new one.

To adjust fan belt tension:

1. Loosen the alternator mounting bolts. Figure 4-21

WARNING: Hydraulic fluid escaping under pressure may have sufficient force to penetrate skin and cause serious injury. Foreign fluid injected into the skin must be surgically removed within a few hours by a doctor, familiar with this form of injury, or gangrene may result.

Before applying pressure to hydraulic system, make sure all connections are tight and all hoses and lines are in good condition. To find a leak under pressure, use a piece of cardboard or wood — never use your hands. Relieve all pressure in the system before disconnecting or working on hydraulic lines. To relieve pressure, lower all attachments and shut off engine.

Checking Oil Level:

Check the oil level every 50 hours.

1. With the tractor standing level and the engine off, check the oil level with the dipstick. Figure 4-22

2. The oil is at the correct level when the oil level is within the mark at the lower end of the dipstick. If low, add ISO

VG46 hydraulic oil, through the filler hole. Do not fill beyond the mark on the stick, as the transmission will be overfilled.

3. Install the dipstick.

Changing Oil & Filters:

NOTE: Replace the filters after the first 50 hours of operation and every 500 hours or annually thereafter following the procedure below:

Change the oil every 500 hours or annually.

1. With the oil at normal operating temperature, drain and discard the oil by removing the transmission drain plug.

Reinstall the plug after the oil has drained. Figure 4-23

Screw the filters into place until the gasket contacts the sealing surface, then tighten the filters approximately 3/4 of a turn by hand. Do not over tighten. Figure 4-24 &

Figure 4-25

4. Remove the filler plug and dipstick and fill with ISO

VG46 hydraulic oil.

5. The transmission is filled to the correct level when the oil level is within the mark at the lower end of the dipstick.

Do not fill beyond the mark on the stick, as the transmission will be overfilled.

6. Install the dipstick and filler plug.

7. Start the engine and check the hydraulic oil filter for leaks.

8. Stop the engine and check the hydraulic oil level.

Replenish if necessary.

IMPORTANT: The transmission, front axle and hydraulic system operate from a common oil sump. Special attention must be given to keeping oil clean.

NOTE: Place the dipstick/filler plug into the oil inlet to measure the oil level. Do not screw dipstick into housing when checking oil level. Figure 4-26

2. If the level is low, add ISO VG46 hydraulic oil through the filler hole. Do not fill above the dipstick full mark.

3. Reinstall the dipstick/filler plug.

Change the oil every 500 hours or annually.

1. With the oil at normal operating temperature, drain the oil by removing the rear axle and final reduction gear case drain plugs. Reinstall the plugs after the oil has drained.

Discard the oil. Figure 4-27 & Figure 4-28

2. Supply new ISO VG46 hydraulic oil into the fill hole until oil level is between the two marks on the dipstick.

Figure 4-26

3. To fill the final reduction gear cases with new ISO VG46 hydraulic oil:

a. Remove the right and left rear wheels.

b. Oil supply plugs are located on the front side of the right and left final reduction gear case. Remove the plugs. Figure 4-29

Figure 4-28

1. The PTO control lever must move easily (soft), through the first 50% of travel. The remaining 50% of control lever travel must have a resistance (hard).

2. At the point of resistance (50% into the control lever stroke), attach a pull scale to the PTO control lever. A reading of 11.5 lbs (5 kg) is correct at the point of

109627_0910

Final reduction gear case fill plug

Figure 4-29 resistance (50% into the control lever stroke). A reading of 26.4-28.6 lbs. (12-13 kg) is correct at the full engagement point (the final 50% of control lever travel).

If the control lever stroke is not correct, or the amount of resistance on the pull scale at the point of resistance is incorrect, proceed to step 3.

NOTE: The adjustment bolt on the PTO adjustment linkage uses left-hand threads.

3. Loosen the locknuts on the PTO adjustment linkage.

Figure 4-30

4. Turn the adjustment rod and recheck the resistance on the pull scale and the control lever stroke. Repeat this step until the control lever stroke and the pull resistance are correct.

5. Tighten the locknuts.

Locknuts in. (10mm) or more than 0.75 in. (19mm) of free play in the park brake lever (Figure 4-31), the park brake is dragging, or the park brake is not working effectively.

1. Park tractor on level ground, lower the mower deck or front mount attachment to the ground, turn off tractor, and remove key. Chock the front drive tires to keep machine from rolling.

2. Check the park brake lever free travel distance: With the park brake lever all the way down (Off), pull the lever up until you notice resistance from brake engagement measure this distance as shown in Figure 4-31. This free play distance should be 0.38 in. (10mm) to 0.75 in.

(19mm).

3. To adjust the park brake free play, raise the seat platform and secure it in the up position.

IMPORTANT: Make sure the seat platform is secured properly in the up position to prevent it from falling back down on you as you are working.

4. Loosen the jam nuts on each of the park brake cable inline cable adjuster barrels as shown in Figure 4-32.

Back the jam nuts off several turns.

5. Turn the in-line cable adjuster barrel (Figure 4-32) on each cable accordingly to properly adjust the cable.

Lengthening the in-line cable adjuster assembly

(exposing more threads) will tighten the cable and reduce the free play. Shortening the in-line cable adjuster assembly length (less exposed threads) will loosen the cable and create more free play. Both cables should be adjusted so they are providing equal free play when the brake is off, and equal brake force on each brake when the park brake is applied.

6. Re-check the free play (step 2). Re-adjust as necessary.

7. Tighten the jam nuts.

Once the park brake is adjusted properly, check to make sure it is working effectively and does not drag. If any problems persist, do NOT operate the tractor, and contact your dealer.

c. When the brakes are dragging.

1. Park tractor on level ground, lower the mower deck or attachment to the ground, turn off tractor and remove key.

Chock the front drive tires to keep machine from rolling.

Make sure the park brake is in the OFF position.

2. Check the free travel of the brake pedal (Figure 4-33 &

Figure 4-34). This is determined by the distance the brake pedal travels from its rear most position pushing forward on the pedal until you feel the brakes beginning to engage. Measure this distance - if it is more than 0.75

in. (19mm) or less than 0.38 in. (10mm), the brakes must be adjusted.

3. The brake linkage rods are located underneath the floor pan. (Figure 4-35) Loosen the jam nuts located behind the front clevis on each of the brake linkage rod assemblies. Back the jam nuts off. Figure 4-36

4. Adjust the brake linkage rods accordingly until the proper brake pedal free play is achieved. Make sure the right and left brake linkage rod lengths are adjusted equally.

5. Re-check the pedal free play (step 2). Re-adjust as necessary.

6. Tighten the jam nuts against the clevis base.

Once the brakes have been properly adjusted, check to make sure they are working correctly on the tractor in a safe area away from any obstructions or bystanders. Make sure the braking force on both front drive wheels is equal. Re-adjust if necessary.

If you find that the brakes are dragging, check the park brake adjustment. If this does not fix the problem and your brakes continue to work incorrectly, do not operate the tractor and contact your Hustler Dealer.

Rear wheel toe adjustment

1. Park the tractor on a flat, level surface with the rear wheels oriented so the tractor will drive a straight line forward.

2. Fully engage the park brake, lower the front end attachment, and turn off the tractor. Remove the keys.

Chock the front drive tires of the tractor.

3. Measure 'F' and 'R' dimensions: The distance between the inside of the rim edge of the RH wheel to the LH wheel. This measurement needs to be taken at the points

4. The 'F' dimension should be between 0.075" and 0.175"

(1.9 mm - 4.4 mm) less than 'R' dimension.

5. If the toe-in must be re-adjusted to meet the dimensional requirements, loosen the jam nuts on either end of the tie rod. Figure 4-38

6. Once the jam nuts are both loose and backed off, rotate the tie rod in the appropriate direction and adjust accordingly to meet the dimensional requirements of step

#4.

7. Tighten the jam nuts on either end of the tie rod. Make sure the ball joints on each end move freely once jam nuts are tightened.

STORAGE

When storing the unit at the end of the operating season, the following steps should be taken to ensure readiness for the next season.

1. Remove all grass, dirt, and trash from tractor and mower. Clean tractor and mower and touch up all scrapes with Hustler spray paint.

IMPORTANT: Wash the machine with a mild detergent and water. Do not pressure wash the machine. Avoid excessive use of water

2. Install new air filter per Engine Owner’s Manual.

3. Check thoroughly for any worn or damaged parts that need replacing and order them from your dealer.

4. If the tractor does not have a deck mounted, raise the lift arms hydraulically to their fully raised position so that the lift cylinder is fully retracted. This will protect the cylinder rod surfaces from corrosion.

5. Lubricate the unit. Drain and refill the transmission, hydraulic system and front axle with new oil.

6.

7.

Block tractor up so weight is off tires.

Do not deflate tires.

8. Perform separate engine preparation as listed below.

9. Store tractor in a clean, dry place.

10. Remove the battery from machine

a. Clean battery

b. Check the electrolyte level

c. Charge the battery, if necessary

d. Store battery in a cool, dry place (do not expose to freezing temperatures)

e. Always keep the battery fully charged. (Especially important to prevent battery damage when the temperature is below 32 o F (0 o C).)

Preparation of engine for storage

When engine is to be unused for long periods, proceed as follows:

1. Run engine for a minimum of 15 minutes.

2. Drain oil from crankcase while engine is still warm.

3. Refill with fresh oil of proper viscosity.

4. Special precautions should be taken to protect the fuel injection pump and injector nozzle against corrosion and gumming.

5. Flush the fuel system with a special oil, a quantity of which will remain in the system when the engine is shutdown. Special diesel fuel system flushing oils are available from most oil companies. If this oil is not available, mix 0.5 qts.(0.5 liters) of SAE 10 nondetergent engine oil with 2.64 gal. (10 liters) of No. 2 diesel fuel. Drain the fuel tank and pour 1.85 gal. (7 liters) of the special flushing oil (or lubricating mixture) into the fuel tank. Run the engine for 10 minutes to ensure complete distribution of the special oil through the injection pump and fuel injectors. There is no need to remove the injector nozzles.

6. Fill the fuel tank with No. 1 diesel fuel. IMPORTANT:

Do not use No. 2 diesel fuel, for winter storage, because of wax separation and setting at low temperature.

7. Open the drain valve on the radiator. Flush the system, close the drain valve and fill with a 50/50 solution of permanent antifreeze and clear water..

8. Clean exterior surface of engine. Spread a light film of oil over any exposed metal surfaces of engine that are subject to corrosion.

9. Clean dirt and chaff from radiator fins and muffler.

10. Check oil filler cap and fuel tank cap to make certain they are securely in place.

11. Refer to engine manual for more information.

New season preparation

Before starting the tractor following post season storage, the following servicing is required:

1. Clean tractor, removing trash and dirt accumulation.

2. Check engine oil level and common sump (for the hydraulic lift, transmission, front axle and power steering) and the rear axle.

3. Install a fully charged battery.

4. Check the cooling system for proper level of 50/50 solution of anti-freeze and clear water.

5. Tighten any bolts that have loosened and make sure all hair pins, cotter pins and clevis pins are in place.

6. Install all safety shields and review safety precautions listed in this manual.

7. Check and inflate tires to 14-18 psi (96-124 KPA).

8. Refer to engine manual for more information.

9. Start the engine and allow it to idle a few minutes. Be sure the engine has proper oil pressure and that each control is functioning properly.

10. Drive the unit without load and check to be sure it is operating satisfactorily.
