To the new owner
The purpose of this manual is to assist owners and operators in
maintaining and operating the Hustler Z 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 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 operators and
mechanics read and understand this manual and the Quick Reference
Decals before operating this machine. It is also the owner’s responsibility
to make certain that the operators and mechanics are qualified and
physically able individuals, properly trained in the operation of this
equipment. All operators and mechanics must become familiar with the
safe operation of its equipment, operator controls and safety signs before
operating the equipment.
Never let children or untrained people operate or service the equipment.
Local regulations may restrict the age of the operator.
The owner/user can prevent and is responsible for accidents or injuries
occurring to themselves, other people or property.
IMPORTANT: For more detailed maintenance and adjustment
information refer to the proper parts manual for your machine. Refer to the
Product Literature section of this manual for ordering information.

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.

through your local Hustler dealer. To obtain prompt, efficient service,
always provide the following information when ordering parts:
1. Correct part description

All warranty repair and service must be handled through an authorized
Hustler dealer. Arrangements should be made through your local service
center.

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

OPERATION
Safe Operating Practices

▲ Never direct discharged material toward anyone. Avoid discharging
material against a wall or obstruction. Material may ricochet back
towards the operator. 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!
▲ Always keep clear of the mower blades and attachments during
operation.
▲ 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 mower-related injuries. These
operators should evaluate their ability to operate the mower safely
enough to protect themselves and others from serious injury.
▲ Follow the manufacturer’s recommendation for wheel weights or
counterweights.
▲ 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.
▲ Clean flammable material from machine. Prevent fires by
keeping engine compartment, exhaust area, battery, fuel line,
fuel tank and operator’s station clean of accumulated trash,
grass clippings, and other debris. Always clean up spilled fuel
and oil.
▲ Always buckle seat belt, if provided with one, and only if a ROPS is
installed properly, before starting tractor.

Some of the following safety instructions are from ANSI Standard B71.4-2004 while others are specific to the Hustler Mid Mount Z line.
This product is capable of amputating hands and feet and throwing
objects. Always follow all safety instructions to avoid serious injury or
death.

Operation
▲ Evaluate the terrain to determine what accessories and attachments
are needed to properly and safely perform the job. Only use
accessories and attachments approved by the manufacturer.
▲ Never leave a running machine unattended. Always stop on level
ground, disengage deck clutch, place steering control levers in park
brake position, stop tractor engine, and remove ignition key before
leaving operator’s seat for any reason including emptying the catcher
or unclogging the chute.
▲ Do not change the engine governor setting or overspeed the engine.
▲ Always remain seated while operating machine.
▲ Always keep safety shields and covers in place, except for servicing.
▲ Always maintain a safe distance from people and pets when
mowing. Always stop machine if someone enters the area.
▲ Always operate machine in daylight or with adequate working lights.
▲ Follow daily and weekly checklists, making sure hoses are tightly
secured and bolts are tightened.
▲ Always observe traffic laws while driving machine from one
location to another. Watch for traffic when operating near or
crossing roadways.
▲ Always be alert for hazards such as rocks, metal objects and other
debris which may be thrown or entangled by mower blades. Watch
out for holes or deep depressions.
▲ Inspect area to be mowed for hazards such as rocks, metal objects
and other debris which may be thrown or entangled by mower
blades. Remove these objects before mowing.
▲ Always inspect machine for damage after striking a foreign object. If
damage is found, repair machine immediately. Be sure to stop on
level ground, disengage deck clutch, place steering control levers in
park brake position, stop tractor engine, and remove ignition key
when leaving operator’s seat to inspect damage.
▲ 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.
▲ Do not operate the equipment while wearing sandals, tennis shoes,
sneakers, shorts or any type of loose fitting clothing. Long hair,
loose clothing or jewelry may get tangled in moving parts. Always
wear long pants, safety glasses, ear protection and safety shoes when
operating this machine.
▲ Always be aware of what is behind the machine before backing up.
Do not mow in reverse unless absolutely necessary. Always look
down and behind before and while backing up.
▲ Never push forward suddenly on your control levers while the
machine is in rearward motion because machine may tip backwards.
▲ Never pull back suddenly on your control levers while the machine
is in forward motion.
▲ When moving in reverse, push forward slowly on control 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 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 carry passengers.

Using a ramp
▲ Use extreme caution when loading and unloading a unit onto a truck
or trailer 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

Slope Operation

Slopes are a major factor in loss-of-control and tip-over accidents,
which can result in severe injury or death. All slopes require extra
caution. If you cannot back up the slope or if you feel uneasy on it; do
not mow it. REMINDER: Only operate on slopes of 15 degrees or less.
▲ Use extreme caution when operating on slopes.
• Be extremely careful changing directions on a slope. Slow down.
• Do not operate where the machine could slip or tip.
• Turn slowly
• Turn on the most level part of the slope
• To maximize traction, it is better to turn the front of the machine
uphill, rather than downhill. If drive tires lose traction, steering
control is lost which could cause serious injury or death.
• If it becomes necessary to turn downhill, turn slowly and
gradually, if possible.
▲ Do not remove or modify the stabilizer wheels.
▲ Watch for holes, ruts, bumps, rocks or other hidden objects. Uneven
terrain could overturn the machine. Tall grass can hide obstacles.
▲ Remove obstacles such as rocks, tree limbs, etc.

The attachments mounted to the tractor will also affect the way it
handles on a slope. Be aware that each attachment’s characteristics
vary.
Do not tow on slopes. The weight of the towed equipment may
cause loss of traction and loss of steering control.
Another consideration to safe mowing on slopes is to be aware of
what is located at the bottom of the slope. Extreme caution should
be used when there is a hazard located at the bottom of the slope.
Some examples are:
1. Water; i.e. lake, river
2. Cliffs, retaining walls
3. Roads, highways
4. Buildings
5. Rocks
These are just a few examples of situations when caution must be
used when operating on a slope. There are many other possibilities
too numerous to mention. Just remember to always exercise extreme
caution when operating on any slope.
▲ When operating on terrain where there is a potential for a roll
over, it is important that a ROPS be installed on the equipment.
The ROPS will minimize chance of injury or death from rollover.
Seat belt must be fastened while operating a machine equipped
with ROPS. Failure to use seat belt will result in serious injury in
the event of a roll over.

▲ 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.
▲ Mow a safe distance (minimum of 10 feet) away from drop-offs,
retaining walls, drainage ditches, embankments, water, and other
types of hazards to avoid a wheel dropping over the edge or to avoid
the ground from breaking away. This will reduce the risk of the
machine suddenly rolling over causing serious injury or death.
▲ Use a walk behind, push mower or hand-held trimmer on slopes and
near drop-offs, retaining walls, drainage ditches, embankments and
water to avoid machine rollover and serious injury or death.
▲ Do not mow on wet grass. Slippery conditions reduce traction
which could cause sliding and loss of control.
▲ Do not tow on slopes. The weight of the towed equipment may
cause loss of traction and loss of control.
▲ Do not try to stabilize the machine by putting your foot on the
ground.
▲ If the mower’s tires lose traction when operating on slopes,
disengage the blades, place the control levers in the park brake
position, turn the engine off and get help.
▲ 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 control levers in
either direction could result in a reaction of the tractor that can cause
serious injury.
▲ Never stop suddenly while backing down slopes. This action may
result in a reaction of the tractor that can cause serious physical
injury.
▲ 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.

Children
Tragic accidents can occur if the operator is not alert to the presence of
children. Children are often attracted to the machine and the mowing
activity. Never assume that children will remain where you last saw
them.
▲ Never leave machine unattended with ignition key in switch,
especially with children present.
▲ 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.
▲ Keep children out of the mowing area and under the watchful care of
a responsible adult other than the operator.
▲ 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.
Children who have been given rides in the past may suddenly appear
in the mowing area for another ride and be run over or backed over
by the machine.
▲ Never allow children to operate the machine.
▲ Never allow children or others in or on towed equipment.
▲ Use care when approaching blind corners, shrubs, trees, the end of a
fence or other objects that may obscure vision.

Do not operate on slopes greater than 15 degrees.
Refer to Figure 2-1, page 7, when determining the degree of slope to
be mowed.
IMPORTANT: The Hustler ATZ only, is capable of operating on
slopes of 15 degrees or more (maximum 25 degrees). Do not
operate the Hustler ATZ on slopes greater than 25 degrees.
Refer to Figure 2-1, page 7 when determining the degree of slope to
be mowed.
It is strongly recommended that the operator drive the machine
off of the slope, using extreme caution, if any sign of loss of traction
is detected. Wait until the condition that caused the problem is
resolved before attempting to operate on the slope again.
Terrain conditions can affect traction resulting in possible loss of
control of the machine. Some of the conditions to be aware of are:
1. Wet terrain
2. Depressions in the ground; i.e. holes, ruts, washouts
3. Mounds of dirt
4. Soil type; i.e. sand, loose dirt, gravel, clay
5. Grass type, density, and height
6. Extremely dry conditions of grass
7. Tire pressure

Safety start interlock system

Ambient
temperature

The tractor is equipped with a safety start 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 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: Always pull from the tractor hitch. Do not
attach chains or ropes to the ROPS for pulling purposes, as
the machine can tip backwards.
Always fasten seat belt during operation of the machine (mower
equipped with ROPS in “raised/up” position).
Inspect the area to be mowed for proper overhead clearance (tree limbs,
guy wires, doorways, etc)
Do not contact any overhead object with the ROPS.
Inspect the seat belt system (all seat, seat belt parts, seat pan and seat
pan latch) daily prior to mowing for signs of any damage. These parts
should be replaced if any parts indicate signs of:
1. cuts
2. fraying
3. extreme or unusual wear
4. significant discoloration due to UV exposure
5. dirt or stiffness
6. abrasion to the seat belt webbing
7. damage to the buckle, latch plate or hardware.
8. or any other problem

Figure 3-13
Possible damage to the ROPS
If the unit has rolled over or the ROPS has been in some other type of
accident (such as hitting an overhead object during transport), the ROPS
must be replaced to retain the best protection.
Following an accident, check the ROPS, the operator’s seat, and the
seat belt and seat belt mountings for possible damage, Before operating the
machine, replace all damaged parts.
IMPORTANT: Do not attempt to weld or straighten the ROPS.
WARNING: If the ROPS or cab is removed or replaced,
make sure that the proper hardware is used and the
recommended torque values are applied to the attaching
bolts.

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

Operating suggestions

Driving the tractor

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.

DANGER: Never make sudden stops or reverse direction,
especially when maneuvering on a slope. 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. 314).
To go in reverse, pull control levers rearward an equal distance (Fig. 314).
To turn left, move the right control lever farther forward from neutral
than the left control lever.(Fig. 3-14)
To turn right, move the left control lever farther forward from neutral
than the right control lever. (Fig. 3-14)
“0” degree turn, move one control lever forward and the other control
lever back of neutral. This will allow the drive wheels to counter-rotate.
(Fig. 3-14)
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.
For emergency stop, when traveling forward or rearward, place the
steering control levers in the park brake position immediately.

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 steering 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. The machine can spin
very rapidly. Use caution when making turns and slow down
before making sharp turns.
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.

DANGER: When moving in the rearward direction push
forward gently on steering 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, causing serious injury or death.

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.

To make a three point turn to the right, move the left control lever
farther forward from neutral than the right control lever and start the turn.
Next, pull back on the control levers until they are past neutral and the
machine starts to go rearward. Pull right control lever farther rearward
from neutral than the left control lever until the rear of the machine has
pivoted around. Then, push the control levers forward until they are both
past neutral and the machine starts to go forward. Push the left control
lever farther forward from neutral than the right control lever and finish the
turn. (Fig. 3-15)
IMPORTANT: Rapid movement of control levers is not recommended

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.
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.

Step 2

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!

Ri

Use high blade speed. Your mower 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 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 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.

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 Hustler Mid Mount Z units.
These anti-scalp wheels are designed to minimize scalping when mowing
on rough uneven terrain.
After setting the cutting height, adjust the front 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” (6.35MM to 19.05MM) below the deck. With the unit
sitting on a flat level surface, the front wheel position can be adjusted up or
down as needed from 3/4” to 1-3/4” (19.05MM to 44.45MM) below the blade
surface. Move the front wheels up or down, in 1/2” (12.70MM) increments,
using the different axle mount holes in the wheel mount bracket. Fig. 3-18
When adjusting the rear anti-scalp wheels, the wheel should be in the
lower axle mount hole when the front anti-scalp wheels are in the lower or
middle axle mount holes. When the front wheels are in the upper axle
mount hole, the rear wheels should be in the upper axle mount hole as well.
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” (1.91CM).

Adjusting
holes

Figure 3-18
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. Do not operate the mower without
either the discharge chute or the entire grass collection system
in place. Fig. 3-16

BAC-VACTM Mounting
If a BAC-VAC™ is to be mounted to an Hustler ATZ tractor it will be
necessary to remove the following from the unit:
1. Drive wheel weights
2. Frame weights located between the drive wheels
3. The front and rear mount legs of the ROPS structure. The two post
ROPS structure will remain. Fig. 3-19
The weights included with the BAC-VAC™ will be used instead of the
Hustler ATZ tractor weights.
If a BAC-VAC™ is mounted to the Hustler ATZ it will be necessary to
remove the BAC-VAC™ and front wheel weights from the tractor and it
will be necessary to re-attach the drive wheel weights, frame weights and
the front and rear mount legs to the tractor before operating the unit on a
slope.

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. 3-1) 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.

ATZ Tilt Seat
ATZ units produced after 081100000 will have a tilt seat as standard
equipment. When the switch, located on the right steering control lever is
depressed, the seat will tilt up to 15 degrees, from center, both directions.
Fig. 3-20

Deck cutting height adjustment
Deck height is adjustable from 1” to 5” (2.54 CM - 12.7 CM) in 1/4” (.64
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. 3-17
EXAMPLE: When the height adjusting stop is placed in the 1” (2.54
CM) hole, with the 1/4” (.64 CM) plate facing to the front of the unit, the
cutting height is at 1”. When the height adjusting stop is placed in the 1”

before cleaning. Use a stick to clear a plugged discharge area.
Never use your hand!
▲ 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.
▲ Exercise caution when working under the deck as the mower blades
are extremely sharp. Wrap the blade(s) or wear gloves and use extra
caution when servicing them.
▲ Use only genuine Hustler replacement parts to ensure that original
standards are maintained

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

Service
▲ Unless specifically required, DO NOT have engine running when
servicing or making adjustments to tractor. Park the machine on
level ground. Place steering control levers in the park brake
position, disengage deck clutch, lower deck, remove ignition switch
key and disconnect negative battery cable before doing any
maintenance. Wait for all movement to stop before adjusting,
cleaning or repairing. Repairs or maintenance requiring engine
power should be performed by trained maintenance personnel only.
To prevent carbon monoxide poisoning, be sure proper ventilation is
available when engine must be operated in an enclosed area. Read
and observe safety warnings in front of manual.
▲ Before working on or under the deck, make certain engine cannot be
accidentally started. Shut engine off, remove ignition switch key
adn disconnect negative battery cable for maximum safety. Repairs
or maintenance requiring engine power should be performed by
trained maintenance personnel only.
▲ Except when changing or checking belt, always keep belt covers on
mower deck for safety as well as cleanliness.
▲ 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.
▲ 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, top of deck, exhaust area, battery,
hydraulic lines, fuel line, fuel tank and operator’s station clean
of accumulated trash, grass clippings, and other debris. Always
clean up spilled fuel and oil.
▲ Always wear adequate eye protection when servicing the hydraulic
system and battery, 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 attempt to start engine when there is a strong odor of gasoline
fumes present. Locate and correct cause.
▲ Never remove the fuel cap or refuel tractor while engine is running;
never refuel near an open flame or near devices which can create a
spark. Refuel outdoors. Never refuel or drain the fuel from the
machine indoors.
▲ 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 maintenance 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.
▲ Do not touch hot parts of machine.
▲ Keep nuts and bolts tight, especially the blade attachment bolts.
Keep equipment in good working condition.
▲ Never tamper with safety devices. Check their proper operation
regularly.
▲ Stop the engine before removing the grass catcher or unclogging the
discharge chute. Never clear the discharge chute with the engine

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. The following pages contain suggested maintenance
information and schedules which the operator should follow on a routine
basis. For more detailed information order the correct parts manual for
your unit. Refer to the Product Literature section of this manual.
Remain alert for unusual noises, they could be signaling a problem.
Visually inspect the machine for any abnormal wear or damage. A good
time to detect potential problems is while performing scheduled
maintenance service. Correcting the problem as quickly as possible is the
best insurance.
Clear away heavy build-up of grease, oil and dirt, especially in the
engine and under the seat platform areas; minute dust particle are abrasive
to close-tolerance engine and hydraulic assemblies.
Daily inspect mower for grass clippings and wire and string tangles.
The underside of the mower deck will collect a build-up of grass clippings
and dirt, especially when grass is wet or has high moisture content. This
build-up will harden, restricting blade and air movement and will probably
show a poorer quality of cutting. Therefore it should be removed routinely.
To do this it will be necessary to raise and block the deck, using jack
stands or blocks, in the full up position and scrape the build-up from
underneath.
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.

The fuel tanks are located in the tractor’s fenders. These engines
requires number 2 diesel fuel only.
Hustler Z Shibaura Diesel tractors are equipped with a fuel shutoff valve
located to the right rear of the seat. Rotate the valve to the middle position
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. Fig. 4-4
If the diesel fuel system runs dry, use the following procedure when restarting the engine:
1. Refill the fuel tanks.
2. Make sure the fuel shutoff valve is turned to the full fuel tank.
3. Take the priming bulb and compress it until it becomes firm. Fig. 4-5
4. Try and start the engine. If it will not start after 15 seconds of
cranking, repeat Step 3.
5. If after trying several tries, the engine still will not start, contact your
Hustler Dealer.

WARNING: Gasoline or diesel fuel is harmful or fatal if
swallowed.
Long-term exposure to vapors can cause serious injury and
illness.
Avoid prolonged breathing of vapors.
Keep face away from nozzle and gas tank or fuel container
opening.
Keep gas away from eyes and skin.

recommendations after that. If tractor is being operated in extremely dirty
conditions, then it is recommended oil be changed more frequently.

Engine air filter
Perform engine air filter maintenance per the Service Interval chart
shown elsewhere in this manual.
A specially designed dry filter is standard equipment on these tractors
and supplies clean combustion air to the engine. Some examples of the air
filter are shown in Fig. 4-6 & 4-7.
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.

Safety filter

Safety filter
Some Hustler tractors are equipped with a safety filter. The filter
element slides over the safety filter.
NOTE: The safety filter does not require servicing unless it becomes
contaminated with dirt or moisture. Fig. 4-8

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 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

Figure 4-8
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

be released, causing serious burns or possible blindness. Fig.
4-10

Figure 4-11

Engine cooling is accomplished with circulated water and Ethylene
Glycol mixture. The radiator is equipped with a pressure cap and overflow
reservoir. Follow the information found in the engine owner’s manual for
the recommended coolant solution.
Visually inspect the system daily prior to operating tractor. Be sure the
engine is level. Check the coolant level only when the system is cold.
Check the coolant level only at the overflow reservoir (Fig. 4-10). The
cooling system is a closed type. Never open the radiator cap. Doing so
may induce air into the cooling system and may cause overheating. The
coolant level should be between the “H” and “L” marks.

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 Kohler EFI engine owner’s manual for
specific cleaning instructions.

Belts
Diesel Units

Inspect 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.

DANGER: Never remove radiator cap or overflow reservoir
cap when engine is hot. Pressurized hot steam and water may
be released, causing serious burns or possible blindness. Fig.
4-11

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.

Engine cooling is accomplished with circulated water and Ethylene
Glycol mixture. The radiator is equipped with a pressure cap and recovery
tank. 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 left rear of the engine (Fig.
4-11). When the engine is cold the coolant should be up to the cold mark
on the recovery tank. When the engine is hot the coolant should be up to
the hot mark on 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.

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.

Do not re-use spindle bolts which have stripped, worn or undercut
threads. Torque bolts on spindles to 118 foot-pounds (160.0 Nm) when
reinstalling blades.
IMPORTANT: When mounting blades, rotate them after installation to
ensure blade tips do not touch each other or sides of the mower.

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: Failure to correctly torque the bolt may result in
the loss of the blade which can cause serious injury.

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. Replace worn or damaged
blades.

WARNING: Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution when servicing
them.

Control lever adjustment
The steering control levers can be adjusted for operator comfort. By
loosening the cap screws that attaches the upper control lever to the lower
lever (Fig. 4-15), the upper control lever can be pivoted to fit the operator’s
personal preference.
The steering control levers should be adjusted so that they align with
each other when in the neutral position.

WARNING: Always wear adequate eye protection when
grinding mower blades.
Warped Blade (Replace)

Mower blade removal

Cutting
Plane

Use a 15/16" wrench to remove the 5/8" cap screw holding the blade to
the spindle shaft from underneath. NOTE: A blade holding tool (part
number 381442) is available from Hustler Turf Equipment. It is designed
to prevent the blades from rotating when they are being removed or
installed on the spindle. Contact your Hustler dealer for more information.
Sharpen the blades on a grinder following pattern as shown (Fig. 4-12).
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. 4-13 and
4-14). Replace any distorted blade.

STORAGE
Preparation of batteries for storage

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.

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.)

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.

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.

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.

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 8-12 psi (55-83 KPa).
7. Install fully charged batteries and attach the battery cables.
