To the new owner
The purpose of this manual is to assist owners and operators in maintaining and operating the Hustler Super Z Diesel tractor and deck. Please read it carefully; information and instructions furnished can help you achieve years of dependable performance.
A separate Engine Manual is included with your owner’s packet which contains additional engine information that will not be repeated in this manual. You are urged to read it before attempting any operation or repair of the engine.
The Quick Reference Decals, located under the right front of the seat, the right front of the deck, and under the seat pan, are designed to give the operator brief information needed in the daily operation of the machine. These decals are not intended to be used in place of this manual but instead are to be used as an extension of this manual. These decals should not be removed or obliterated. Replace these decals if they become unreadable.
It is the owner’s responsibility to make certain that the operator reads and understands this manual and the Quick Reference Decals before operating this machine. It is also the owner’s responsibility to make certain that the operator is a qualified and physically able individual, properly trained in the operation of this equipment. Local regulations may restrict the age of the operator.
Using this manual
General operation, adjustment and maintenance guidance is outlined for both the experienced and novice Hustler user. Operating conditions vary considerably and cannot all be addressed individually. Through experience, however, operators should find no difficulty in developing good operating skills suitable to most conditions.
Directions used in this manual, for example RIGHT or LEFT, refer to directions when seated on tractor facing forward, unless otherwise stated.
Photographs and illustrations used were current at the time of printing, but subsequent production changes may cause your machine to vary slightly in detail. Hustler Turf Equipment reserves the right to redesign and change the machine as deemed necessary, without notification. If a change has been made to your machine which is not reflected in this owner’s manual, or the parts manual, see your Hustler dealer for current information and parts.
Warranty registration
The Delivery and Warranty Registration form must be completed and signed to validate your warranty protection. As the new equipment owner, you are expected to see that the form is completed and forwarded to Hustler Turf Equipment at time of delivery.
Be sure to register the tractor plus each attachment that displays a model and serial identification number plate with Hustler Turf Equipment.
IMPORTANT: Any unauthorized modification, alteration, or use of non-approved attachments voids the warranty and releases Hustler Turf Equipment from any liability arising from subsequent use of this equipment.
Model and serial number
Tractor model and serial numbers are found on the serial identification plate, located on the frame directly below and to the left of the operator’s platform.
These numbers are required on the Warranty Registration form. They will also assure you of the correct service parts when replacement becomes necessary.

SAFETY PRECAUTIONS
Page 10
Never push forward suddenly on the steering control levers while the machine is in rearward motion because the machine may tip backward.
When moving in reverse, push forward slowly on levers and avoid sudden movement. Rapid movement of the control levers in either direction could result in a reaction of the tractor that can cause serious injury.
Never operate a poorly maintained machine.
Never carry passengers.
Never attempt high speed maneuvering, especially in crowded or congested areas.
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.
Never put hands or feet under any part of the machine while it is running.
Never leave machine unattended with ignition key in switch, especially with children present.
Never refuel tractor while engine is running; never refuel near an open flame or near devices which can create a spark. Refuel outdoors preferably, or in well ventilated areas.
Never attempt to start engine when there is a strong odor of diesel fumes present. Locate and correct cause.
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.
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 deck clutch is engaged. Repairs or maintenance requiring engine power should be performed by trained personnel only.
Never work under the machine or attachment unless it is safely supported with stands, blocks or a hoist.
Do not touch hot parts of machine.
Never direct discharge of material from mower deck towards bystanders. Do not operate the mower without either the discharge chute or the entire grass collection system in place.
Always disengage the blades and wait for them to stop before crossing gravel drives, walks or roads.
Always keep clear of the mower blades and attachments during their operation.
Turn off blades when not mowing.
Slow down before turning.
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!
Do not operate the machine while under the influence of alcohol or drugs.
Exercise caution when loading or unloading the machine onto a trailer or truck.
Always wear safety goggles or safety glasses with side shields when operating the mower.
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.
Always disengage the blades and wait for them to stop before crossing gravel drives, walks or roads.
Always keep clear of the mower blades and attachments during their operation.
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 lever in either direction could result in a reaction of the tractor that can cause serious injury.
If any attachment or additional weight is mounted on the rear of the unit, any rapid movement of the control levers in either direction could result in a reaction of the tractor that can cause serious injury.
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.
Do not remove or modify the stabilizer wheels.
Remove obstacles such as rocks, tree limbs, etc.
Keep all movement on slopes slow and gradual. Do not make sudden changes in speed or direction.
Avoid starting and stopping on a slope. If tires lose traction, disengage the blades and proceed slowly straight down the slope.
Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.
Do not mow near drop-offs, ditches, or embankments. The machine could suddenly turn over if a wheel goes over the edge of a cliff or ditch, or if an edge caves in.
Do not mow on wet grass. Reduced traction could cause sliding.
Do not try to stabilize the machine by putting your foot on the ground.
Watch for holes, ruts or bumps. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
Keep children out of the mowing area and under the watchful care of another responsible adult.
Be alert and turn the machine off if children enter the area.
Before and while backing, look behind and down for small children.
Never carry children, even with the blades off. They may fall off and be seriously injured or interfere with safe machine operation.
Never allow children to operate the machine.
Use care when approaching blind corners, shrubs, trees, the end of a fence or other objects that may obscure vision.
Use extra caution when handling gasoline and other fuels. They are flammable and vapors are explosive.
Keep nuts and bolts tight, especially the blade
351254_041505

351254_041505
2-3
attachment bolts. Keep equipment in good condition.
Never tamper with safety devices. Check their proper operation regularly.
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.
Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves and use extra caution when servicing them.
Use only genuine Hustler replacement parts to ensure that original standards are maintained
Do not remove or modify the stabilizer wheels.
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 the machine on slopes greater than 15 degrees.
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.
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 many other possibilities too numerous to mention. Just remember to always exercise extreme caution when operating on any slope.
Clean flammable material from machine. Prevent fires by keeping engine compartment, 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.
Specific safety warning decals are located on the equipment near the immediate areas of potential hazards. These decals should not be removed or obliterated. Replace them if they become non-readable.

Do not smoke while refueling. Do not fill tank with engine running, or while the engine is hot. Allow engine to cool before storing machine inside a building. Store away from open flame or spark if there is fuel in tank. Clean up any gasoline spills. Do not refuel while in enclosed trailer or other enclosed areas
Avoid skin 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 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. Use soda mixed in water to clean corrosion off the terminals.
Hydraulic fluid escaping under pressure can penetrate skin. Hydraulic fluid may also cause infection in a minor cut or opening in the skin; if exposed to hydraulic fluid, see a doctor at once. Before applying pressure to hydraulic system, make sure all connections are tight and all hoses and lines are in good condition. Relieve all pressure in the system before disconnecting or working on hydraulic lines. To find a leak under pressure, use a piece of cardboard or wood – never use your hands. To relieve all pressure in system, turn engine off and lower attachment.
Read Owner’s Manual and Quick
Reference Decal before attempting to
operate this machine.
The following illustrations show the various safety decals that are located on the machine. A brief explanation is shown to
help the operator understand the meanings of these decals.
Do not remove or modify stabilizer wheels or injury can result. Never stop suddenly while backing down slopes. This action may result in a reaction of the tractor that can cause serious physical injury.
Never operate the mower deck with side deflector removed or in raised position, except when the grass catcher attachment is being used.
Hot surface!
Keep shields or covers in place while machine is in operation. Keep hands away from rotating pulleys and belts.
Whirling blades! Keep hands and feet away. Beware of thrown objects.
Avoid crushing Do not jump if machine tips Use seat belt Seat belt must be fastened while operating this machine. Failure to use seat belt will result in serious injury in the event of a roll over.
Use seat belt.
This structure’s protective capability may be impaired by structural damage, overturn, or alteration. To minimize chance of injury or death from rollover; keep ROPS in the raised and locked position and use the seat belt. 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 sloper operation instructions and warnings. Do no wear seat belt when the ROPS is in the lowered position.

If light comes on during operation, shut engine off immediately, locate and correct the problem. If light remains on while engine is running, it indicates the that the batteries are being discharged.
Safety interlock system
The tractor is equipped with a safety interlock system consisting of the park brake switches, seat switch, and deck clutch switch.
Check tractor safety start interlock system daily, prior to operation. This system is an important tractor safety feature. It should be repaired immediately if it malfunctions. The machine incorporates a separate seat switch which will stop the tractor engine when the operator is unseated for any reason while the tractor is operating. This is a safety feature designed to prevent runaway or accidental entanglement. To inspect the system:

1. The operator must be on the seat when testing the seat
switch.
2. Set both control levers in the park brake position.
3. Start the engine and allow it to warm up to operating
temperature.
4. With the deck clutch switch down and the control
levers in the park brake position, slowly raise off of the seat. The engine should continue to run.
5. With the deck clutch switch up and/or the control
levers in the neutral position, slowly raise off of the seat. The engine should stop.
6. If the engine fails to stop when the deck clutch switch
is up or one or both of the control levers is up(out of the park brake position) and the operator is off the seat, check the function of the seat switch. If the seat switch is not operating properly (is not opening or closing) and if the cause can not be determined, replace the seat switch.
If the problem can not be located, contact your Hustler
Dealer.
WARNING: The safety interlock system should always function per steps 4 and 5. If it does not function properly, it should be corrected immediately. Do not operate machine without properly functioning seat safety switch.
Engine starting
The Hustler Super Z Diesel safety start interlock system is also designed to protect the operator and others from accidental injury due to unintentional engine starting. The engine starting motor will not engage until:
A. Control levers are in the park brake position. B. Deck clutch switch is in the down (OFF) position.
WARNING: The safety interlock system must not be disconnected or bypassed.
NOTE: The operator’s seat is equipped with a separate safety switch. If for any reason the operator should become unseated when the brake switches are disengaged or the deck clutch switch is engaged the engine will stop.
The following steps are the correct procedures for starting the engine. If difficulty is encountered, contact the Hustler Dealer in your area.
1. Before starting tractor each day, perform daily pre-
operation checking.
2. Make sure the control levers are in the park brake
position and deck clutch switch is disengaged.
3. Set throttle at approximately 1/2 open position.
4. Insert key in ignition switch and rotate it to the ON
position, then hold the pre-heat switch down to pre­heat the engine, hold this position for 6 seconds. This is necessary only when the temperature is below 50o F. This operation is not necessary when restarting a warm engine. Shown in the chart are the standard preheating times for various temperatures. This operation, however, is not required when the engine is warmed up.
Failure to follow these recommendations can lead to premature failure of the starter motor and the fuel shut-off solenoid. NOTICE: Ether, or other starting fluids, must never be used as a starting aid with this engine. Warranty will be denied when engine damage results from such use.
5. Rotate ignition switch key full clockwise to engage
starting motor. Release key when engine starts.
IMPORTANT: The engine starter should not be operated for periods longer than 30 seconds at a time. An interval of at least two minutes should be allowed between such cranking periods to protect the starter from overheating and burn-out.
6. Perform test to make sure safety start interlock system
is operating properly. Refer to Safety start interlock system section.
7. As soon as engine begins to run, check to make certain
the oil warning light is off. If not, stop engine immediately and check for the cause.
8. Allow the engine to idle a few minutes before
advancing the throttle and/or engaging the deck clutch.
9. Before stopping the engine, place the control levers in
the park brake position, disengage the deck clutch, and throttle back to low idle for a couple of minutes; then rotate ignition key counter-clockwise to the OFF position. Remove the key from switch before leaving the tractor.
WARNING: Never leave the machine unattended with key in ignition switch.

Page 18
Moving tractor with stalled engine
If it becomes necessary to move the tractor when the engine is inoperative, the hydraulic pumps are equipped with bypass valves. Before moving the unit, turn bypass valves counter clockwise one-half to one revolution. The valve stems on each hydraulic pump are located on the top of the pump and are identified as a hex stud. Figure 3-8
Do not tow the machine. Move it by hand or use a winch to load on a trailer for transporting.
When transporting on another vehicle, the tractor should be facing forward and it must be secured.
IMPORTANT: Always make certain the two bypass valves are returned to their operating position before running the tractor following repairs.
ROPS
The two-post ROPS can be pivoted down so that the
machine can operate under low hanging tree limbs or other obstructions. Do not wear the seat belt when the ROPS is in the lowered position. Fig. 3-10
WARNING: To minimize chance of injury or death from rollover: keep ROPS in the raised and locked position and use the seat belt. 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.
Driving the tractor
DANGER: Never make sudden starts, stops or
reverse direction, especially when going up a slope because the mower may tip backwards. The steering is designed for sensitive response. Rapid movement of the control levers in either direction could result in a reaction of the tractor that can cause serious injury.
After starting engine, engage the control levers and steer
as follows:
To go forward, push control levers forward an equal
distance (Fig. 3-9).
To go in reverse, pull control levers rearward an equal
distance (Fig. 3-9).
To turn left, move the right control lever farther forward
from neutral than the left control lever.(Fig. 3-9)
To turn right, move the left control lever farther forward

from neutral than the right control lever. (Fig. 3-9)
To pivot turn, move one control lever forward and the
other control lever back of neutral. This will allow the drive wheels to counter-rotate. (Fig. 3-9)
To stop or decrease speed, move control levers to
neutral. When going forward pull back gently on control levers. When going in reverse push forward gently on control levers.
DANGER: When moving in the rearward direction push forward gently on control levers and avoid sudden movement. Any sudden movement could cause the front of the mower to come off of the ground resulting in possible loss of control.
WARNING: Never stop suddenly while backing down slopes. This action may result in a reaction of the tractor that can cause serious physical injury.
To increase speed, increase control lever’s distance from
neutral. The farther forward control levers are from neutral, the faster tractor will travel forward. The farther back control levers are from neutral, the faster tractor will go in reverse.
Operating suggestions
DANGER: Prior to operating the tractor the
operator should be thoroughly familiar with the proper use and operation of the equipment, should read the manual completely and thoroughly, and should have attempted slow moving maneuvers to become familiar with the operation of the equipment before attempting normal speed operation. An inexperienced operator should not mow on slopes or on uneven terrain.
WARNING: If you lose steering control while operating the machine, place the steering control levers in the park brake position immediately. Inspect the machine and involve your Hustler dealer to resolve the problem before continuing to operate.
WARNING: The unit’s control levers are very responsive: Easy does it! For smooth operation, move lever slowly, avoid sudden movement. Skill and ease of operation come with practice and experience.
WARNING: Children or bystanders may be injured if they move or attempt to operate the tractor while it is unattended. Always disengage deck clutch, place control levers in park brake position, stop tractor engine, and remove ignition key when leaving operator’s seat.
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.
When turning on soft wet turf, keep both wheels rolling either forward or backward. Pivoting on one stopped wheel can damage turf. This is especially important when mowing.
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 control levers to control ground speed rather than engine rpm.
WARNING: Do not operate the equipment while wearing sandals, tennis shoes, sneakers, shorts or any type of loose fitting clothing. Always wear long pants, safety glasses, hearing protection and safety shoes when operating this machine.
Keep blades sharp. Many professional mowing companies have additional sets of blades and change blades twice a day: once in the morning and again at noon. Many
problems with incorrect cutting patterns are due to dull blades or blades which have been sharpened incorrectly.
Information on sharpening blades is listed in this manual’s maintenance section. In addition, most communities have individuals or companies which specialize in sharpening mower blades. Blade sharpness should be checked daily.
Use high blade speed. Your Hustler Super Z Diesel is designed to operate at full throttle. The throttle setting directly controls blade speed. The highest blade speed generally gives best cut.
Direct grass discharge to right, away from unmown

chute
Page 20
area. Select a mowing pattern that directs grass discharge towards the outside, not towards center, of mowing area. Generally, this means using a pattern utilizing left turns because side discharge (Fig. 3-11) is to right. In any case, avoid throwing grass discharge onto unmowed area because grass is then mowed “twice”. Mowing twice puts an unnecessary load on the unit and reduces mowing efficiency.
When mowing a lawn for the first time cut grass
slightly longer than normal to avoid scalping uneven terrain. When possible, it is best to use the cutting height that was used in the past. When cutting grass taller than six inches, you may want to mow the lawn twice to achieve a better quality of cut.
During normal mowing cut only about 1/3 of the grass
blade. Cutting more than that is not recommended unless
grass is sparse or it is the end of the mowing season.
Alternate mowing direction to keep the grass growing
straight and better dispersion of the clippings.
Remember, grass grows at different rates at different
time of the year. Mow more often in the early spring to maintain the same cutting height. As the growth rate slows in mid summer, mow less frequently. If you cannot mow at a regular interval, mow at a high cutting height; then mow again two days later at a lower cutting height.
Raise the cutting height of the mower if the cutting
width of the mower is wider than the previous mower. This ensures that uneven turf is not cut too short.
Raise the cutting height of the mower if the grass if
slightly taller than normal or if it contains a high degree of moisture. Then mow it again with the cutting height set lower.
If the machine’s forward motion must be stopped while
mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged.
WARNING: Never direct discharge of material from mower deck towards bystanders.
WARNING: Never operate the mower deck with discharge chute removed or in raised position.
WARNING: Always check area to be mown for rocks and other debris before mowing.
Mower deck operation
DANGER: Never attempt to make any
adjustments to the mower deck while the engine is running or with the deck drive clutch engaged. Mower blades cannot be seen and are located very close to deck housing. Fingers and toes can be cut off instantly.
With the engine running, engage the deck clutch switch
(Fig. 3-2) and advance engine throttle to full rpm.
NOTE: Engaging the deck clutch at high engine rpm or when under heavy load (in tall grass for example) can cause belts and/or electric clutch to slip, resulting in premature wear or possible damage.

Introduction
WARNING: Unless specifically required, DO
NOT have engine running when servicing or making adjustments to tractor. Place control levers in the park brake position, disengage deck clutch, and remove ignition switch key. Repairs or maintenance requiring engine power should be performed by trained 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.
DANGER: Before working on or under the deck, make certain engine cannot be accidentally started. Shut engine off and remove ignition
switch key for maximum safety. Repairs or maintenance requiring engine power should be performed by trained personnel only.
DANGER: Exercise caution when working under the deck as the mower blades are extremely sharp. Wearing gloves is advisable when working around or with the blades.
WARNING: Except when changing or checking belt, always keep belt covers on mower for safety as well as cleanliness.
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.
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.
WARNING: Keep your machine clean and remove any deposits of trash and clippings, which can cause engine fires and hydraulic overheating as well as excessive belt wear.
Clear away heavy build-up of grease, oil and dirt, especially in the engine and hydraulic reservoir area; minute dust 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 in the full up position and scrape the build-up from underneath.
WARNING: When possible clean under mower, using a stick or similar instrument making sure that no part of the body, especially arms and hands are under mower.
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.

Blade spindle bolt top........................65-75......88.14-101.7
Blade spindle bolt bottom.....................118 ................160.0
It is recommended that these be checked after the first 2 hours of operation, initially and every 50 hours following removal for repair or replacement.
For all other torques refer to the tractor parts manual for standard torque chart.
For engine torque values, see engine owner’s manual.
Tires
It is important for level mowing that the tires have the same amount of air pressure. The recommended pressure are:
Drive wheels............................8-10psi (55-69
KPa)
Gauge wheels..........................8-10 psi (55-69 KPa)
Solid fill tires are not recommended for Hustler turf equipment. On any machine, with solid filled tires, the warranty claim will be denied.
WARNING: Explosive separation of a tire and rim can cause serious injury or death. Do not attempt to mount a tire without the proper equipment and experience to perform the task. Always maintain the correct tire pressure and never over inflate. Never weld or heat a wheel and tire assembly as an explosion may occur. Welding can weaken or deform a wheel. When inflating tires stand to one side and not in front of or over the tire assembly. Check tires for low pressure, blemishes, damaged rims or missing lug bolts and nuts.
Hour meter
To recognize when your machine needs servicing, check the hour meter and the maintenance schedule. The hour meter shows the number of hours the engine has run and the maintenance schedule lists the service intervals. Fig. 4-2
Lubrication
Grease the following areas per the Maintenance
Schedule. Use SAE multi-purpose grease.
1. Front gauge wheel bearings
2. Four deck lift pivots, located to the side of the
operator’s footrest
3. Deck idler
4. Pump idler pivot
5. Two deck pusher arm pivots
6. Blade spindle assemblies The spindle assemblies
require lubrication annually. Each spindle shaft is equipped with a grease zerk located under the deck. Use no more than one or two ounces of SAE multi­purpose grease, (1 to 2 pumps on an average grease gun). Do not force lubricant in to grease zerks. Bearings are sealed and do not require much lubricant.
Electrical system
The electrical system is a 12 volt, negative ground. Recommended battery size is a garden tractor BCI group U1R with 225 or better cranking AMP rating. Two maintenance-free batteries are recommended. Otherwise, follow battery manufacturer’s maintenance, safety, storing and charging specifications.
The batteries are located under the seat. Fig. 4-3
WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to cause cancer and reproductive harm. Wash hands after handling.
WARNING: Avoid skin 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 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. Use soda mixed in water to clean corrosion off the terminals.
Figure 4-2
Hour
meter
Page 25
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.
Common circuit failures are usually caused by shorting, corroded or dirty terminals; loose connections, defective wire insulation or broken wires. Switches, solenoids and ignition components may also fail, causing a shorted or open circuit.
Before attempting any failure diagnosis of the electrical system, use a test light or voltmeter to check the battery voltage. If the battery voltage is satisfactory, check the cleanliness and tightness of the terminals and ground connections. A general understanding of electrical servicing and use of basic test equipment is necessary for troubleshooting and repair.
Major overhaul or repair of the starting motor or alternator should be performed by trained technicians only.
Access to engine and hydraulic pumps
The hydraulic pumps are accessed by lifting the seat
platform. The seat platform is hinged at the front. To raise it, release seat latch and tilt seat platform up and forward. The seat platform catch (Fig. 4-4) will prevent the seat from going all the way over. However, if more access is desired under the seat platform, the seat platform catch can be raised allowing the seat to pivot more. Make certain to place the
control arms in the park brake position and pivot the arm rests upward before placing the seat platform in the full forward position to prevent arm rest damage.
The engine can be accessed from the rear of the machine without removing the engine shroud. If additional access is required, remove the engine shroud.
WARNING: Always wear adequate eye protection when servicing the hydraulic system and battery.
Hydraulic system
IMPORTANT: Never use hydraulic or automatic
transmission fluid in this system; use only motor oil as specified. Remember, dirt is the primary enemy of any hydraulic system.
WARNING: Hydraulic oil escaping under pressure can penetrate skin. Hydraulic oil may cause infection in a minor cut or opening in the skin. If exposed to hydraulic fluid, see a doctor at once.

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.
The 3.0 U.S. gallon (11.4 liter) hydraulic reservoir is part of the radiator housing. The fill neck is the left neck on the top of the radiator housing. Fig. 4-5
Check oil level in hydraulic system after every 50 hours of operation or weekly, whichever occurs first. Check more often if system appears to be leaking or otherwise malfunctioning.
Fluid level should be 3” (7.62
CM) from the top of fill
neck. Use only SAE 10W40 SG, SF/CC, CD service motor oil.
Change hydraulic system filter element (Fig. 4-6) after first 50 hours of tractor operation, then replace filter and oil in reservoir every 500 hours thereafter.
The system filter is located next to the left drive wheel on the tractor frame. A standard oil filter wrench is used to change filter, threads are right handed. Use a Hustler
approved filter element only.
IMPORTANT: Prefill the filter element with clean oil, before installing, to prevent drawing air into the system
pump.
NOTE: Install new hydraulic filter element immediately after the removal of the old filter to minimize oil loss from reservoir.
1. Fill the filter element with clean system oil. Smear a
light coating of oil on upper surface of rubber seal.
2. Install the filter element on base. Tighten the oil filter
by hand until the filter seal makes contact with the filter head, then tighten an additional 3/4 - 1 turn with an oil filter wrench. — DO NOT OVERTIGHTEN.
3. Start tractor engine and let run at approximately 2/3
throttle for a few minutes to work any trapped air out of the system before engaging the steering control lever.
4. Stop the engine and check the filter and connections
for leaks.
5. Check the hydraulic reservoir for specified oil level.
Add clean oil as necessary.
Clean or replace hydraulic reservoir cap annually. Cap may be cleaned by dipping in or flushing with cleaning solvent. Follow manufacturer’s instructions and warnings for application of solvent type selected.
NOTE: The hydraulic pumps are equipped with bypass valves. For more information refer to Operation section, Moving tractor with stalled engine.
A hydraulic oil heat exchanger is installed on the Super Z Diesel. This heat exchanger is designed to keep hydraulic system oil temperature lower in hot operating conditions or

heavy continuous operating conditions.
This hydraulic heat exchanger is part of the radiator housing. The air is drawn across the cooling fins by the left electric fan located to the rear of the radiator housing. Fig. 4-6
NOTE: The electric fans will perform a test cycle where they will push the air and then will auto reverse and pull air before reversing and pushing the air.
The deck blades are powered by a hydraulic motor. This motor provides power to the deck spindle drive belt. Fig. 4­7
Fuel system
WARNING: Observe usual fuel handling
precautions; do not smoke while refueling, do not fill tank with engine running or while engine is hot; 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 if there is fuel in the tank. Read and observe safety precautions at front of this manual.
WARNING: Fuel System Under Pressure! The fuel system operates under high pressure, and the fuel filter and fuel line used must be approved system components only. Use of substitute parts can result in system failure, fuel leakage and possible explosion.
The fuel tanks are located in the tractor’s fenders. (Fig. 4-8) Total capacity for the fuel tanks is 18 U.S. gallon (68.1 liter)
This engine requires number 2 diesel fuel only. The fuel filter is located on the left, rear side of the engine. Change filter after every 100 hours of operation or annually,
whichever occurs first. Fig. 4-9
When replacing the fuel filter, check the fuel line hoses
for any cracks or leaks. Replace as needed.
Super Z Diesel tractors are equipped with a fuel shutoff valve located to the right rear of the seat (Fig. 4-10). Rotate the valve to the middle position (shown) to allow fuel to
flow from the right fuel tank to the fuel pump. The right position prevents fuel flow to the fuel pump. The left position allows fuel to flow from the left fuel tank to the fuel pump. Close this valve to prevent fuel flow to the engine when servicing the fuel system or when transporting the unit on a trailer or truck.
Diesel engines are subject to air blockage whenever the fuel tank runs empty, the fuel filter has been removed, any fuel lines have been disconnected or removed and replaced, or when the tractor has been stored for a period of time. Should such air blockage occur, it will be necessary to bleed the system, removing any trapped air between the fuel tank and filter, then trapped air between the filter and injector pump as follows:
1. Fill the tank with fresh fuel and make sure the shut-off
valve is open at tank.
2. Loosen the vent screw (Fig. 4-9) located on top of the
fuel filter and leave it open until air bubbles are no longer present, then close the vent screw.
3. Start the engine and run at low rpm for 15 to 30
seconds to expel air from pump, then close the air vent screw.
4. If engine fails to start, repeat steps 2, 3 and 4.

located on top and rear of the engine (Fig. 4-11). Tractor must be setting level when checking oil. Refer to engine
manual and maintenance schedule for oil recommendation and capacities.
Change the engine oil and filter after the first 5 hours of operation, per the engine manufacturer’s recommendations after that. If tractor is being operated in extremely dirty conditions, then it is recommended oil be changed more frequently.
The oil drain and oil filter are located at the lower rear of the engine. Fig. 4-12
Engine air filter
Perform engine air filter maintenance per the Service Interval chart on page 4-2.
A specially designed dry filter is standard equipment on the Super Z Diesel tractors and supplies clean combustion air to the engine. Fig. 4-13
Air service indicator
The Super Z Diesel has an air service indicator installed in the air cleaner. Fig. 4-13 & 4-14
Replace the element whenever the service indicator reaches the change filter red line. Check the indicator daily and replace element as needed or annually whichever occurs first.
Reset the indicator by pushing in on the yellow button after each element change. Fig. 4-14
A service indicator takes the guesswork out of air cleaner servicing and allows you to safely benefit from the filter’s optimum performance.
Safety filter
The Super Z Diesel is equipped with a safety filter. The filter element slides over the safety filter. Use Hustler part number 785279 only when replacing the safety filter.
NOTE: The safety filter does not require servicing unless it becomes contaminated with dirt or moisture.
Recommended service procedure
Many engine failures can be attributed to improper air cleaner servicing. Ingested dust and dirt will cause cylinder,
piston and bearing damage in a few hours. “Dusted” engines will result from:
1. Overservicing the air filter element.
2. Improper installation.
3. Damaged filter, seals or canister.
4. Incorrect air filter element size.
5. Use of poorly designed aftermarket air filter elements.
Air cleaner servicing is an inexpensive maintenance check that can prevent costly non-warrantable premature engine damage.
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.
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 Donaldson
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.
Improper installation of an air filter element
Dust must not leak past the seals on each end of the air filter element. The filter must be aligned within the canister and properly seated for an effective seal so that no dirt can enter the engine.
Damaged filter, seals or canister
Never bang or bump the filter element against the tire or any solid object, as dust and dirt particles will be forced through the media causing continual passing of dirt into the engine. Visually inspect the outside of the air cleaner canister periodically for external damage and replace if necessary.

Cooling system
Engine cooling is accomplished with circulated water and Ethylene Glycol mixture. The radiator is equipped with a pressure cap and recovery tank. System capacity is approximately 3.0 U.S. gallon (11.36 liter). A 50-50 mixture is recommended for all season operation. This mixture provides freeze protection to -32 degrees F (-35 degrees C). Should temperatures fall below this level, additional Ethylene Glycol must be added to the mixture.
Visually inspect the system daily prior to operating tractor. Check coolant level in the recovery tank located to the front left of the radiator assembly (Fig. 4-15). When the engine is cold there should be 1” (2.54 CM) of coolant in the recovery tank. When adding coolant, pre-mix the solution before adding it to the recovery tank. It is not necessary to remove radiator cap for adding small amounts of coolant to system.
DANGER: Never remove radiator cap when engine is hot. Pressurized hot steam and water may be released, causing serious burns or possible blindness.
The system should be drained, flushed and refilled with fresh solution after every 500 hours of operation.
If frequent refilling is necessary or if coolant appears

Incorrect air cleaner element
Use only the correct Donaldson air filter element, Hustler part number 785261, which is designed to fit the canister properly.
Hustler air filter elements have the correct media composition, filter area, micron size and dimensions. Always use genuine Hustler filters. Many aftermarket filters have been found to be incompatible with Hustler’s canisters and engines.
The air filter must remain intact to block passage of dirt and foreign particles from entering the engine. Being inclined to disbelieve the need for more expensive air filter elements used on diesel engines may cause some individuals to opt for a less expensive part.
The filter element must be sufficient size and construction to withstand stresses, caused by rapid cycling of the air volume demanded by the engine, without cracking or tearing under fatigue and pressure (especially diesel engines). Therefore, Hustler Turf Equipment and the engine manufacturers have carefully selected a reliable filter designed to fit the needs of the engines. The filter specified is a Donaldson filter, Hustler part number 785261.
Owners should be reminded that failure to use original equipment replacement parts is an “alteration” and will not be considered for warranty in the event of engine damage.
Recommended service procedure
1. Release clamps and remove element. Clean the
canister with a damp cloth.
2. 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.
3. Reinstall the dust cup. Make sure it seals all the way
around the air cleaner body, then tighten the clamps.
4. Check all fittings and clamps periodically for tightness
and inspect hoses for holes or cracks.
5. Periodically check the intake hose for signs of ingested
dust. Locate and repair the source of ingested dirt.
6. Never operate a machine without an air filter installed.

rusty, thoroughly check the system. Refer to the engine manual for information on checking and cleaning system.
The air is pushed across the radiator cooling fins by the right electric fan located at the rear of the radiator housing. Keep the radiator and hydraulic heat exchanger area clean at all times and make sure trash is not allowed to accumulate, nor allow the fins and cores to become plugged.
NOTE: The electric fans will perform a test cycle where they will push the air and then will auto reverse and pull air before reversing and pushing the air.
Never force anything into the radiator fins which may
bend or distort them. For cleaning, use compressed air only.
General engine maintenance
Detailed instructions and recommendations for break-in and regular maintenance are specified in the Engine Owner’s manual. Please refer to this manual for engine servicing, lubricating oil levels with quality and viscosity recommendations, bolt torques, etc. The engine warranty is backed by the manufacturer. Special attention should be paid to applicable data which will not be duplicated here.

IMPORTANT: Refer to the Caterpillar engine owner’s
manual for specific cleaning instructions.
Belt replacement
Figures 4-17, 4-18 and 4-19 show diagrams and
descriptions of the unit’s belt drive systems.
Inspect these belts frequently for wear and serviceability. Replace a belt that shows signs of severe cuts, tears, separation, weather checking and cracking, or burns caused by slipping. Slight raveling of belt covering does not indicate failure, trim ravelings with a sharp knife.
WARNING: If the pump belt fails, loss of control will occur especially when operating on a slope. If you lose steering control while
operating the machine, place the steering control levers in the park brake position immediately. Inspect the machine and involve your Hustler dealer to resolve the problem before continuing to operate.
Inspect the belt pulley grooves and flanges for wear. A new belt, or one in good condition, should never run against the bottom of the groove. Replace the pulley when this is the case, otherwise belt will lose power and slip excessively.
Never pry a belt to get it on a pulley as this will cut or damage the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt dressings. Any of these will destroy the belt composition in a very short time.
Mower blade maintenance
Check the mower blades daily, they are the key to power efficiency and well groomed turf. Keep them sharp, a dull blade will tear rather than cut the grass, leaving a brown ragged top on the grass within a few hours. A dull blade also requires more power from the engine.
Replace any blade which is bent, cracked or broken.
WARNING: Never attempt to straighten a bent blade by heating, or weld a cracked or broken blade as the blade may break and cause serious injury.
DANGER: Never work with blades while engine is running or deck clutch is engaged. Always place deck clutch in the disengaged position, place steering control levers in the park
brake position and turn engine off. Block up mower when you must work under it. Wear gloves when handling blades. Always check for blade damage if mower strikes rocks, branches or other foreign object during mowing!
Mower blade removal
Use a 15/16" wrench to remove the 5/8" cap screw
holding the blade to the spindle shaft from underneath.
Sharpen the blades on a grinder following pattern as shown (Fig. 4-20). Touch-up sharpening can be done with a file.
Check the blades for balance following grinding. A commercial balancing tool is available through most hardware supply stores, or balancing can be done by placing the blade on an inverted line punch or 1/2" bolt. Blade should not lean or tilt. Spin the blade slowly, blade should not wobble. If blade is out of balance, true it up before reinstalling.
Lay the blade on a flat surface and check for distortion (Fig. 4-21 and 4-22). Replace any distorted blade.
Do not re-use spindle bolts which have stripped, worn or undercut threads. Torque bolts on spindles to 118 foot­pounds (160.0
Nm) when reinstalling blades.
WARNING: When mounting blades, rotate them after installation to ensure blade tips do not touch each other or sides of the mower.
WARNING: Failure to correctly torque the bolt may result in the loss of the blade which can cause serious injury.
WARNING: Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves and use extra caution when servicing them.

ADJUSTMENTS
Introduction
WARNING: Unless specifically required, DO
NOT have engine running when servicing or making adjustments to tractor. Place control levers in the park brake position and remove ignition switch key. Repairs or maintenance requiring engine power should be performed by trained 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.
Your Super Z Diesel was adjusted before it left the factory and was checked during predelivery setup. However, after start-up and break-in some adjustments could change.
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.
WARNING: Keep your machine clean and remove heavy deposits of trash and clippings, they can cause engine fires and hydraulic overheating as well as excessive belt wear.
Clear away heavy build-up of grease, oil and dirt, especially in the area of reservoir oil and engine combustion air; minute dust particle are abrasive to close-tolerance engine and hydraulic assemblies.
Some repairs require the assistance of a trained service technicians and should not be attempted by unskilled personnel. Consult your Hustler service center when assistance is needed.
Torque values
WARNING: Particular attention must be given
to tightening the drive wheel lug nuts, wheel motor nuts, and blade spindle bolts. Failure to correctly torque these items may result in the loss of a wheel or blade, which can cause serious damage or personal injury.
Torque values given below:
Ft-lbs. Nm
Wheel (lug) nuts ................................65-75......88.14-101.7
Wheel motor nut ...........................350-375 .....474.6-508.5
Blade spindle bolt top........................65-75......88.14-101.7
Blade spindle bolt bottom ....................118 ................160.0
It is recommended that these be checked after the first 2 hours of operation, initially and every 50 hours following removal for repair or replacement.
For engine torque values, see engine owner’s manual. For all other torques refer to the parts manual for
standard torque chart.
Steering linkage
The neutral adjustment for the control levers in the neutral
position is discussed in this section.
The tractor steering has been factory adjusted to eliminate creeping when the control levers are in the neutral position (Fig. 5-1). However, should the tractor begin to creep, the control lever linkage can be adjusted as follows:
Control Lever Neutral Adjustment
Before considering any adjustment, check the tire air pressure and make certain hydraulic system oil is at operating temperature. Unequal tire pressure will cause the tractor to drift to one side. Refer to tire pressure information in the Maintenance section of this manual.

Fine adjustment to the unit’s steering is made with the adjustable pump linkage rods located between the control lever and pump arms. Fig. 5-2
Neutral is properly adjusted when the control levers are in the neutral position and the drive wheels are not turning.
If the tractor creeps in the neutral position the control linkage may be adjusted as follows:
1. Raise and block the tractor up so the drive wheels are
off of the floor.
WARNING: 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.
2. Position the control lever in the neutral position.
Disengage the deck clutch.
3. Disconnect the park brake linkage by removing the
bolt and nut from the turnbuckle. This must be done on both the right and left sides. This linkage is located below the tractor frame just in front of the drive tires. Fig. 5-3
4. Start the engine and observe which way the wheels are
rotating.
5. If wheel(s) are rotating forward, loosen the jam nuts on
the pump linkage rods and rotate the rod to lengthen the steering control linkage until the wheel(s) come to a stop. Fig. 5-2 NOTE: The left linkage controls the left drive wheel and the right linkage controls the right drive wheel . Repeat for the opposite side if necessary.
6. If wheel(s) are rotating in reverse then loosen the jam
nuts on the pump linkage rods and rotate the rod to shorten the steering control linkage until the wheel(s) come to a stop. Fig. 5-2 NOTE: The left linkage controls the left drive wheel and the right linkage controls the right drive wheel . Repeat for the opposite side if necessary.
7. When both wheels remain in neutral, tighten the jam
nuts to lock the turnbuckle in place.
8. Test again by moving the control levers forward and
backward before returning them to the neutral position. If the tires are in neutral, the unit is now ready for operation.
9. After adjusting for neutral it may be necessary to re-
adjust the control lever stop. Fig. 5-4
10. Re-connect the park brake linkage bolt and torque to
33 ft.-lbs (44.75 N
m). Fig. 5-3
11. Remove the tractor from the jack stands.
WARNING: Be sure to reconnect the brake linkage before operating tractor.
Control lever stops
The control lever stops (Fig. 5-4) are designed to do two things: First, and most important, they must keep the pumps from bottoming out internally. Secondly, the stops may be adjusted to help drive straight when the control levers are pushed forward against the stops.
To keep the pumps from bottoming out internally use the following procedure:
1. To make the first adjustment the tractor engine must
NOT be running.
2. Check to make sure the control levers are against the
stops before the pumps are bottomed out internally. To do this, gently and slowly move the control levers forward and feel if there is some resistance on the pump lever before the control levers hit the stops. Check one side at a time. If you sense that the pump arms are stopping the forward motion of the control arms, loosen the jam nut on the adjustable stop of the corresponding side and turn the stop (set screw) inward to stop the control levers slightly before the pump bottoms out. Lock in place when the adjustment is correct by re-tightening the jam nut.
3. Do this for each side.
To adjust the stops for driving straight when control levers are against the stops during operation:
1. Determine which drive tire is rotating too fast when
both control levers are against the stops. Then stop the tractor and loosen the lock nut on the side which is rotating too fast and turn the stop (set screw) inward to

stop the control lever sooner. Tighten the lock nut on the stop and test again. Repeat this procedure until unit drives straight.
NOTE: Since this is a hydrostatic drive, variables such as temperature of oil, efficiency of pumps and motors, tire pressure etc. may effect the consistency of the ability to rely on the stops to drive straight without the operator making minor steering adjustments with the control arms.
Steering dampener
The steering dampener (Fig. 5-5) is spring loaded to return the control levers to the neutral position from the reverse position. This gives the operator a sense of neutral during operation.
To set the steering dampeners in the correct operating position follow these steps:
1. Place the control lever in the neutral position.
2. Loosen the steering dampener’s front ball stud.
3. Compress the dampener spring housing pass the point
that the internal spring is engaged.
4. Release the dampener spring housing and allow the
internal spring to bring the housing back to the neutral position.
5. Tighten the nut on the steering dampener’s front ball
stud.
Control lever adjustment
The control levers can be adjusted for operator comfort. By loosening the cap screws that attaches the upper control lever to the lower lever (Fig. 5-6), the upper control lever can be pivoted to fit the operator’s personal preference.
The control levers should be adjusted so that they align with each other when in the neutral position.
Park brake adjustment
Occasionally check the park brakes and adjustment using the following method:
1. Move the control lever to where it is 1/2” (1.27
CM)
inside the park brake slot. Fig. 5-9 NOTE: When the control lever is against the outside edge of the the slot, the brakes should not be engaged.
2. Hold the control lever in this position. Rotate the
brake linkage to shorten it until the brake acutator lever is rotated forward as far as it will go. Re-tighten

the jam nuts until they are tight against the turnbuckle. NOTE: It may be necessary to loosen the jam nuts before turning the brake linkage.
3. Repeat steps 1 thru 2 for the other side.
4. The brakes should now be set.
Hydraulic pump belt adjustment
The pump belt belt tension remains constant by means of a tension idler and spring (Fig. 5-11). The spring tension should be such that the belt does not slip under normal operating load conditions, assuming the belt is not excessively worn or damaged. As belt stretches and wears, adjustment may become necessary. To increase belt tension, move the spring chain one (or more) link(s) at the anchor bracket (Fig. 5-11). Installed spring length should be 9.0" ± .3" (22.8 cm ± .76 cm) originally with adjustments of .60" (15.2mm) per chain link. (Fig. 5-13)
IMPORTANT: Do not over tension the spring to compensate for a badly worn belt or pulley.
NOTE: Replace the belt every 400 hours or every two (2) years whichever comes first.
WARNING: If the pump belt fails, loss of control will occur especially when operating on a slope. If you lose steering control while
operating the machine, place the steering control levers in the park brake position immediately. Inspect the machine and involve your Hustler dealer to resolve the problem before continuing to operate.
Deck drive belt adjustment
The spindle belt tension remains constant by means of a tension idler and spring (Fig. 5-12). The spring tension should be such that the belt does not slip under normal operating load conditions, assuming the belt is not excessively worn or damaged. As belt stretches and wears, adjustment may become necessary. To increase belt tension, move the spring chain one (or more) link(s) at the anchor bracket (Fig. 5-12). Installed spring length should be 9.0" ± .3" (22.8 cm ± .76 cm) originally with adjustments of .60" (15.2mm) per chain link. (Fig. 5-13)
IMPORTANT: Do not over tension the spring to compensate for a badly worn belt or pulley.
Engine RPM setting
The Super Z Diesel is designed so that the engine will run at the following settings:
High idle - 3100 ±50 rpm At this speed the hydraulic pumps are running at their maximum rated speed. Low idle - 1200 ±50 rpm
Deck leveling and height adjustment
The mower deck has three areas that may need to be checked and adjusted periodically. Before considering any mower deck leveling adjustments, check that the tire air pressure is within the specified range.
Deck level adjustments
Leveling the deck must be done in the following manner
and order:
1. Check tire pressures to make certain they are properly
inflated before starting to level deck. The recommended pressures are as follows:
Drive wheels tire pressure .......8-10 psi (55-69
KPa)
Gauge wheels tire pressure......8-10 psi (55-69 KPa)
WARNING: Stop engine. Make sure deck clutch switch is in the down (OFF) position. Place control levers in the brake position before leaving machine.
2. Park the unit on a flat surface.
3. Raise deck and place 3" (7.62
CM) of blocking under
all 4 corners of the deck (Fig. 5-14). This will set the cutting height at 3 ¼ " (8.26). NOTE: Back of deck

will automatically be set ¼" (.64 CM) higher. NOTE: When blocking up the rear discharge decks make certain the blocks are not in the discharge opening.
4. Set cutting height at 3 ¼" (8.26 CM) in the height
indicator by placing the height adjusting stop in the 3" (7.62 CM) hole, and turning the height stop so that the flat side is against the stop handle. Fig. 5-15 NOTE: Refer to Deck Cutting Height Adjustment section on how to set the cutting height.
5. Clamp the height adjusting stop against the stop handle
(5-15). This will assure that the height will not move during the setting process. Otherwise, spring pressure from the deck lift springs will tend to pull the stop away from the handle.
6. Loosen all nuts on the deck lift threaded rods, and the hardware on the adjuster (on the right front), until all
the deck lift chains are loose, and the deck is sitting tightly on all four blocks. Fig. 5-16, 5-17, 5-18
7. Loosen the two nuts on the front of height indicator so
that the foot pedal is free. Fig. 5-19
8. Start the leveling process on the left front of the
tractor.
9. Set the amount of threads protruding on the deck lift
rod from the lift block at approximately 1" (2.54
CM).
Fig. 5-20
10. Jam both nuts against the block.
11. Push or pull on the deck lift foot pedal until the chain
on the left front just becomes tight, making sure that the deck stays tight against the 3" (7.62 CM) block.
12. While keeping the chain tight, tighten the nuts against
the deck lift block on the height indicator rod. Fig. 5­19
13. Go to the right front of the tractor.
14. Loosen the 5/16" jam nut on the adjuster lift chain (5-
18), and back the adjuster bolt out to allow the adjuster to move up and down freely.
15. Be sure that adjuster is free to move up and down.
16. Tighten the adjuster bolt until the chain just becomes
tight, making sure that the deck stays tight against the 3" (7.62
CM) block.
17. Tighten the adjuster bolt jam nut to prevent the
adjuster bolt from moving. Fig. 5-18

loosen the two nuts on the block holding the threaded rod until there is slack in the deck lift chain. Fig. 5-17
21. Tighten the appropriate nut until the chain just
becomes tight, making sure that the deck stays tight against the 3" (2.54 CM) block.
22. Tighten the other nut on the opposite side of the block,
and jam them tightly together against the block.
23. Go to the left rearof the tractor.
24. Make sure that there is still slack in the chain. If not,
loosen the two nuts on the block holding the threaded rod until there is slack in the deck lift chain. Fig. 5-16
25. Tighten the appropriate nut until the chain just
becomes tight.
26. Tighten the other nut on the opposite side of the block,
and jam them tightly together against the block.
27. Compress the deck lift assist springs so that there is 1”
(2.54 CM) of space between the front nut and on the spring and the rear nut on the deck lift block (Fig. 5-
20). Typical both sides.
28. When completed, all chains will be tight, and deck
cutting height will be set to the deck height indicator.
Deck cutting height adjustment
Deck height is adjustable from 1” to 7” (2.54 cm - 17.78 cm) in 1/4” (.64 CM) increments. The holes in the height adjusting bar are spaced at 1/2” (1.27 CM) intervals. By turning the height adjusting stop around, 1/4” (.64 CM) increments can be attained due to the 1/4” (.64 CM) plate that is part of the stop. Fig. 5-21
There are three (3) holes in each of the four (4) deck chain brackets that are also used for height adjustment. Fig. 5-22
The top hole is used for cutting heights of 1” - 5” (2.54
- 12.70 CM). The following information is to ascertain what
to set the cutting height at when the top hole is used.

The notch located at the rear of the height adjusting bar
is to be used when the deck is placed in the transport mode.
Anti-scalp wheels
Anti-scalp wheel kits are standard on the Super Z Diesel. These anti-scalp wheels are designed to minimize scalping when mowing on rough uneven terrain.
After setting the cutting height, adjust the anti-scalp wheels so they extend below the deck but do not contact the ground. They should always be at least 1/4” to 3/4” (.6 cm to 1.9 cm) below the deck. With the unit sitting on a flat level surface, the wheel position can be adjusted up or down as needed from 3/4” to 1-3/4” (1.9 cm to 9.5 cm) below the blade surface. Move the front wheels up or down, in 1/2” (1.3 cm) increments, using the different axle mount holes in the wheel mount bracket. Fig. 5-23
NOTE: When the anti-scalp wheels are installed, the minimum cutting height is 1” (2.5 cm) with the anti-scalp wheels set at 3/4”.

When storing the unit at the the end of the mowing season, the following steps should be taken to ensure readiness for the next mowing 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.
2. Replace air filter element.
3. Check thoroughly for any worn or damaged parts that
need replacing and order them from your dealer.
4. Thoroughly lubricate machine, according to
lubrication instructions.
5. Check hydraulic oil level. Add oil if necessary or change oil and filter if not done in last 500 hours. Refer to Maintenance section.
6. Block tractor up so weight is off tires. NOTE: Do not deflate tires.
7. Perform separate engine and battery preparation as listed below.
8. Store tractor in a clean, dry place.
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. Drain fuel tanks.
5. Remove and replace fuel filter.
6. Clean exterior surface of engine. Spread a light film
of oil over any exposed metal surfaces of engine that are subject to corrosion.
7. Check oil filler cap and fuel tank cap to make certain they are securely in place.
Preparation of batteries for storage
When the machine is to be unused for long periods, it is best to disconnect the batteries and remove them from the unit. At this time perform the following battery maintenance:
1. Clean battery
2. Check the electrolyte level
3. Charge the battery, if necessary
4. Store battery in a cool, dry place (do not expose to
freezing temperatures)
5. Always keep the battery fully charged. (Especially
important to prevent battery damage when the temperature is below 32F.)
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, hydraulic oil and coolant levels.
3. Fill fuel tanks with fresh fuel. Bleed fuel system as
outlined in Maintenance section. Run machine at half speed for 5 minutes, checking operation of steering control lever. Stop engine and check for oil leaks, loose fittings and so forth.
WARNING: At start of new season always check that fresh oil and coolant have been added to machine. If oil and coolant are drained at season’s end and not replaced, engine damage will result.
4. Tighten any bolts that have loosened and make sure all
hair pins, cotter pins and clevis pins are in place.
5. Install all safety shields and review safety precautions
listed in this manual.
6. Check and inflate tires to 8-10 psi (55-69
