the deck clutch on for 15 seconds, and then off for 15 seconds. Repeat
this operation 10 times, it will require about 5 minutes to complete.

Maintenance & Adjustment Safety
This safety alert symbol is used to call attention to a message intended to provide a reasonable degree of
PERSONAL SAFETY for operators and other persons during the normal operation and servicing of this
equipment.
DANGER – denotes immediate hazards which WILL result in severe personal injury or death.
WARNING – denotes a hazard or unsafe practice which COULD result in severe personal injury or death.
This manual uses two other words to highlight information. IMPORTANT calls attention to special
mechanical information and NOTE: emphasizes general information worthy of special attention.
All operators should read this manual, or be instructed about safe operating and maintenance procedures.
This is the owner’s responsibility.
Improper use or maintenance by the operator, mechanic, or owner can result in injury. To reduce
the potential for injury, comply with these safety instructions and always pay attention to the safety
alert symbol, which means DANGER or WARNING – “personal safety instructions.” Failure to
comply with the instructions may result in personal injury or death.
Incorrect usage of this machine may result in severe injury. Personnel operating and maintaining it
should be trained in the proper use and should read the manuals completely and thoroughly before
attempting to set-up, operate, adjust, or service this machine.
The Quick Reference Decals, located in front of and to the right of the seat, are designed to give the
operator/mechanic brief information needed in the daily operation and service of the machine. These
decals are not intended to be used in place of this manual but instead is 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/mechanic reads and understands this
manual and all decals before operating this machine. It is also the owner’s responsibility to make certain
that the operator/mechanic is a qualified and physically able individual, properly trained in the operation of
this equipment. Local regulations may restrict the age of the operator/mechanic.
The owner should also ensure that the operator/mechanic knows that they are responsible for their own
safety as well as the safety of other persons within the vicinity. Remember, the operator/mechanic is
responsible for accidents or hazards occurring to other people or their property.
Safe Maintenance & Adjustment Practices
This product is capable of amputating hands and feet and throwing objects. Always follow all safety
instructions to avoid serious injury or death.
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, remove ignition switch
key and disconnect the negative battery cable. 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.
Follow daily and weekly checklists, making sure hoses are tightly secured and bolts are tightened.
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. Clean up oil or fuel spillage. Allow
machine to cool before storing.

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.
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.
Never put hands or feet under any part of the machine while it is running.
Except when changing or checking belt, always keep belt covers on mower for safety as well as
cleanliness.
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!
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.
Never leave machine unattended with ignition key in switch, especially with children present.
Be alert and turn the machine off if children enter the area.
Always wear adequate eye protection when servicing the battery, hydraulic system, cooling system or
when grinding mower blades and removing accumulated debris.
Use extra caution when handling gasoline and other fuels. They are flammable and vapors are
explosive.
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 gasoline 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 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 2000
pounds to block the unit up. Use in pairs only. Follow the instructions supplied with the vehicle stands.
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.
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.
Exercise caution when working under the deck as the mower blades are extremely sharp. Wearing
gloves or wrapping the blade(s) is advisable when working around or with the blades.
Do not touch hot parts of machine.
Keep nuts and bolts tight, especially the blade 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.
Use only genuine Hustler replacement parts to ensure that original standards are maintained.

Using a ramp
Use extreme caution when loading and unloading a unit with a ramp.
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.
Do not exceed a 15 degree angle between the ramp and the ground or between the ramp and the
trailer or truck.
When on a ramp avoid sudden acceleration
Safety and Instruction Decals
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.
The following illustrations show the various safety decals that are located on the machine. A brief expla-
nation, for those requiring one, is shown to help the operator understand the meanings of these decals.

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.
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 hydraulic reservoir areas;
minute dust particles 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, using jack stands or blocks,
and scrape the build-up from underneath.
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.
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 are given below:
Ft-lbs.
Nm
Wheel (lug) nuts.................................65-75...........88.14-101.7
Wheel motor nut...............................290-310.........393.2-420.4
Blade spindle bolt top.........................65-75...........88.14-101.7
Blade spindle bolt bottom.....................118.................160.01
It is recommended that these be checked after the first 2 hours of operation initially, every 50 hours, and
following removal for repair or replacement.
For all other torques refer to the various tractor parts manuals for standard torque charts.
NOTE:
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
pressures are:
Drive wheels........................... 8-12 psi (55-69 KPa)
Gauge wheels ............................semi-pneumatic
The bar tread tires are reversed from what is considered the normal operating position. this allows for bet-
ter traction when backing up a slope.

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.

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 infec-
tion 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 1.0 U.S. gallon (3.79 liter) hydraulic reservoir is located in front of the engine and under the operator’s
platform "FIG. 6".
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 1” from top of reservoir. Use only SAE 10W40 SG, SF/CC, CD service motor oil.
Change hydraulic system filter element ("FIG. 6") after first 50 hours of tractor operation, then replace filter
and oil in reservoir every 500 hours thereafter. When changing hydraulic oil use 1/2 unit (approximately
3.5 oz.) of Lubrizol additive (Hustler P/N 027912). This additive, available from your Hustler dealer, will
increase the performance life of the hydraulic system components.

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.
A hydraulic oil heat exchanger is installed on the Super Z. 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 located above the engine. Air is drawn across the cooling fins by an
electric fan located above the heat exchanger "FIG. 7".
Never force anything into the heat exhanger fins which may bend or distort them. For cleaning, use
compressed air or pressurized water only.

FUEL SYSTEM
DANGER: Observe usual fuel handling precautions:
Do not smoke while refueling.
Do not fill tank with engine running or while engine is hot. Clean up any gasoline spills.
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.
Use extra caution when handling gasoline and other fuels. They are flammable and vapors are
explosive. A fire or explosion from gasoline can burn you and others and can damage property.
Refuel outdoors preferably, or in well ventilated areas.
Never attempt to start engine when there is a strong odor of gasoline fumes present. Locate and
correct cause.
Store gasoline in an approved container and keep it out of the reach of children. Never buy more than
a 30 day supply of gasoline.
Always place gasoline containers on the ground away from your vehicle before filling.
Do not fill gasoline containers inside a vehicle or on a truck or trailer as interior carpets or plastic truck
bed liners may insulate the container and slow the loss of any static charge.
When practical, remove equipment from the truck or trailer and refuel the equipment with its wheels on
the ground. If this is not possible, then refuel the equipment on the truck or trailer using a portable
container and not a gasoline dispenser nozzle. If a gasoline 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.
WARNING: Gasoline 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 gas tank or conditioner opening.
Keep gas away from eyes and skin.

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.

108604 10/08
Download from Www.Somanuals.com. All Manuals Search And Download.
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.
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 gasoline 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.
AIR RESTRICTION INDICATOR
Any unit with a Kohler or Kawasaki engine will have an air restriction indicator installed in the air cleaner
"FIG. 13".
Replace the element whenever the restriction indicator shows 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. 13"
A restriction indicator takes the guesswork out of air cleaner servicing and allows you to safely benefit from
the filter’s optimum performance.

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 switch is engaged (on).
Always place deck clutch switch in the disengaged position, place control levers in the park brake
position and turn engine off and disconnect negative battery cable. Block up mower when you must
work under it. Wear gloves when handling blades. Always check for blade damage if mower strikes
rock, branch or other foreign object during mowing!
WARNING: Always wear adequate eye protection when grinding mower blades.
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. 18". 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. 19" and "FIG. 20". Replace any distorted
blade.
Do not re-use spindle bolts which have stripped, worn or undercut threads. Torque bolts to 118 foot-
pounds 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 seri-
ous injury.
WARNING: Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves and use extra
caution when servicing them.

Adjustment
INTRODUCTION
Your Hustler ATZ was adjusted before it left the factory and was checked during predelivery setup.
However, after start-up and continued use, a certain amount of break-in wear will cause some adjustments
to 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.
Clear away heavy build-up of grease, oil and dirt, especially in the area of reservoir and 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 mechanic and should not be attempted by
unskilled personnel. Consult your Hustler service center when assistance is needed.
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. 21". 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. 22".
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: 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 2000 pounds to block the unit up. Use in pairs only. Follow the instructions supplied with the
vehicle stands.
2. Position the control lever in the neutral position. Disengage the deck clutch.
3. Start the engine and observe which way the wheels are rotating.
4. 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. 22". Repeat for the opposite side if necessary.
NOTE:
The left linkage controls the left hydraulic pump and the right linkage
controls the right hydraulic pump.
5. 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. 22". Repeat for the opposite side if necessary.
NOTE:
The left linkage controls the left hydraulic pump and the right linkage
controls the right hydraulic pump.
6. When both wheels remain in neutral, tighten the jam nuts to lock the turnbuckle in
place.
7. 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.
8. After adjusting for neutral it may be necessary to re-adjust the control lever stop
"FIG. 23".
CONTROL LEVER STOPS
The control lever stops "FIG. 23" 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

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 con-
sistency 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. 24", 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. Pull 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. 25", 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. Position the control levers in the neutral position. Disengage the deck clutch.

WARNING: 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 2000 pounds to block the unit up. Use in pairs only. Follow the instructions supplied with the
vehicle stands.
NOTE:
The front brake link is not adjustable. "FIG. 26"
2. Raise and block the tractor up so the drive wheels are off of the floor.
3. Open the hydraulic pump’s bypass valve "FIG. 27", on the side that is being adjusted,
by turning bypass valves counter clockwise one-half to one revolution. The valve
stems on each hydraulic pump are located near the top and are identified as a hex
stud.

4. Rotate the tire. The tire should rotate. Remember hydraulic oil resistance will prevent
the tire from rotating freely even with the bypass valves open. There should be no
resistance from the brakes at this point.
5. Move the control lever to where it is just inside (1/8”) the park brake slot "FIG. 28".
NOTE:
When the control lever is against the outside edge of the the slot, the
brakes should not be engaged.
6. Rotate the tire. If the brake is adjusted properly the tire will still rotate but friction will
start to become noticeable here. However, if no brake resistance is noticed, the brake
needs adjusted as follows:
7. Loosen the brake linkage jam nuts "FIG. 29".

8. Rotate the tire and at the same time rotate the turnbuckle to shorten the length of the
brake linkage to increase the brake pressure. When you feel the brake begin to
engage, stop adjusting the turnbuckle. Re-tighten the jam nuts on the turnbuckle.
9. Place the control lever in the park brake slot "FIG. 28". The tire should not rotate when
the control lever is in the park brake position.
10. Place the control lever in the neutral position. The tire should rotate freely.
11. Close the hydraulic pump’s bypass valve.
12. Repeat steps 3 thru 11 for the other side.
13. Remove the jack stands and lower the unit. It is now ready to operate.
HYDRAULIC PUMP BELT ADJUSTMENT
The pump drive belt tension remains constant by means of a tension idler and spring "FIG. 30". There is
no tension adjustment of this belt.
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. 31". 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 in, adjustment may become
necessary. To increase belt tension, move the spring chain one (or more) link(s) at the anchor bracket
"FIG. 31". Installed spring length should be 9.0" ± .3" (22.8 cm ± .76 cm) originally with adjustments of .60"
(15.2mm) per chain link "FIG. 32".
IMPORTANT: Do not over tension the spring to compensate for a badly worn belt or pulley.

ENGINE RPM SETTING
The Hustler ATZ is designed so that the engine will run at 3600 rpm static pump load only. At this speed
the hydraulic pumps are running at their maximum rated speed.
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 - 12 psi
Gauge wheels tire pressure ........ 8 - 12 psi
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 3.25” block under the back of the deck and a 4” block under the
front of the deck "FIG. 33". This will set the cutting height at 3-1/2 ".
NOTE:
Back of deck will automatically be set approximately ¼" higher.
4. Set cutting height at 3-1/2" in the height indicator by placing the height adjusting stop
in the 3-1/2" hole, and turning the height stop so that the pin side is against the stop
handle "FIG. 34"
5. Clamp the height adjusting stop against the stop handle "FIG. 34". 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.

approximately 1" "FIG. 39".
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 4" block.
12. While keeping the chain tight, tighten the nuts against the deck lift block on the height
indicator rod, just enough to carry most of the deck weight on that side—the 4" block
should be able to move with only a slight drag "FIG. 38".
13. Jam nuts tightly together against the deck lift block.
14. Go to the right front of the tractor.
15. Loosen the 5/16" jam nut on the adjuster lift chain "FIG. 37", and back the adjuster bolt
out to allow the adjuster to move up and down freely.
16. Be sure that adjuster is free to move up and down.
17. Tighten the adjuster bolt until the chain just becomes tight. Then tighten just enough
more to carry the weight of the front of the deck on that side—to check, move the 4"
blocks back and forth; they should move with a slight drag.
18. Tighten the adjuster bolt jam nut to prevent the adjuster bolt from moving "FIG. 37"
19. Tighten the hardware holding the chain and adjuster onto the deck lift arm.
20. Go to the right rear of the tractor.
21. 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. 36".
22. Tighten the appropriate nut until the chain just becomes tight, and carries most of the
deck weight. Check by moving the 3.25" block—it should move with a slight drag.
23. Tighten the other nut on the opposite side of the block, and jam them tightly together
against the block.
24. Go to the left rear of the tractor.
25. 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. 35".
26. Tighten the appropriate nut until the chain just becomes tight, and carries most of the
deck weight. Check by moving the 3.25" block—it should move with a slight drag.
27. Tighten the other nut on the opposite side of the block, and jam them tightly together
against the block.
28. Compress the deck lift assist springs so that there is 1” of space between the front nut
and on the spring and the rear nut on the deck lift block "FIG. 39". Typical both sides.
29. When completed, all chains will be tight, and deck cutting height will be set to the deck
