Safe Operating Practices
This product is capable of amputating hands and feet and throwing
objects. Always follow all safety instructions to avoid serious injury or
death.
Operation
▲Never leave a running machine unattended. Always disengage deck
clutch, place control levers in park brake position, stop tractor
engine, and remove ignition key when leaving operator’s seat.
▲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 disengage
deck clutch, place 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. 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.
▲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 mower-related injuries. These
operators should evaluate their ability to operate the mower safely
enough to protect themselves and others from 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.
▲▲Clean flammable material from machine. Prevent fires by
keeping engine compartment, battery, fuel line, fuel tank and
operator’s station clean of accumulated trash, grass clippings,
and other debris. Always clean up spilled fuel and oil.
Using a ramp
▲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
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.
▲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.
▲Do not remove or modify the stabilizer wheels.
▲Watch for holes, ruts or bumps. Uneven terrain could overturn the
machine. Tall grass can hide obstacles.
▲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.
▲Mow a safe distance (minimum of two mower widths) away from
drop-offs, retaining walls, drainage ditches, steep banks, water, and
other types of hazards to avoid a wheel dropping over the edge or to
avoid the ground from breaking away. This will help avoid machine
rollover and serious injury or death.
▲Use a walk behind or push mower on slopes and near drop-offs,
retaining walls, drainage ditches, steep banks and water to avoid
machine rollover and serious injury or death.
▲Do not mow on wet grass. Reduced traction could cause sliding and
loss of steering 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,

IMPORTANT: When access is required under the seat platform and
the seat is equipped with the optional arm rests, 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.

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.
Do not operate on slopes greater than 15 degrees.
Refer to Figure 2-1, page 9, when determining the degree of slope to
be mowed.
It is strongly recommended that the operator drive the machine
off of the slope, using extreme caution, if any sign of loss of traction
is detected. Wait until the condition that caused the problem is
resolved before attempting to operate on the slope again.
Terrain conditions can affect traction resulting in possible loss of
control of the machine. Some of the conditions to be aware of are:
1. Wet terrain
2. Depressions in the ground; i.e. holes, ruts, washouts
3. Mounds of dirt
4. Soil type; i.e. sand, loose dirt, gravel, clay
5. Grass type, density, and height
6. Extremely dry conditions of grass
7. Tire pressure
The attachments mounted to the tractor will also affect the way it
handles on a slope. Be aware that each attachment’s characteristics
vary.
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.
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
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.

Controls
A. Control levers (Fig. 3-2 & 3-3) — these levers control the tractor’s
speed, direction, neutral lock, and park brake. Levers are used to
steer, accelerate, decelerate and change direction. When the control
levers are in the park brake position (3-3) the tractor will not move
when the engine is on and drive pumps are operating.
WARNING: The parking brake may not hold the tractor if
parked on a slope. Block or chock the machine when parked
on a slope

lower the deck. Push on the pedal to raise the deck and then place
the deck height locking pin into the desired cutting height hole.
Push the deck lift pedal to raise the deck when going over
obstructions.
Safety start interlock system
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: 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 tractor’s 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. Doing so could cause the machine
to operate unexpectedly resulting in personal injury.
NOTE: The operator’s seat is equipped with a separate safety switch.
If for any reason the operator should become unseated when the control
levers are not in the park brake position (park 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. (See Safety start interlock system section)
2. Make sure the control levers are in the park brake position and deck
clutch switch is disengaged.
3. Use choke, if unit is equipped with one, when engine is cold, or if
warm engine fails to start within 5 seconds of cranking. Avoid
flooding and operate engine without choking as soon as possible.
4. Set throttle at approximately 1/2 open position.
5. Insert key in ignition switch and rotate 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, check engine light and alternator warning light (if
applicable) are 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.
Stopping the engine
Use the following procedure to shut off the engine after operating the
equipment.
1. Place the control levers in the park brake position
2. Disengage the deck clutch
3. Throttle back to low idle for a couple of minutes
4. Rotate ignition key counter-clockwise to the OFF position. Remove
the key from switch before leaving the tractor.
Moving tractor with stalled engine
If it becomes necessary to move the tractor when the engine is
inoperative, the transaxles are equipped with bypass valves. Before moving
the unit, pull out on the bypass valve rods and slide them into the slot to
lock in position.
Both bypass valve rods are located underneath the rear of the tractor at
the back of the transaxle. (Fig. 3-5)
The control levers must be placed in the neutral position, to release the
park brakes, so that the tractor can be moved.
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 must be secured.
IMPORTANT: Always make certain the two bypass valves are
returned to their operating position before running the tractor following
repairs.
WARNING: Allow engine exhaust manifold to cool before
engaging or disengaging the bypass valves. The bypass valve
rods are located close to the exhaust system.
Driving the tractor
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. 3-6).
To go in reverse, pull control levers rearward an equal distance (Fig. 3-
6).
To turn left, move the right control lever farther forward from neutral
than the left control lever.(Fig. 3-6)
To turn right, move the left control lever farther forward from neutral
than the right control lever. (Fig. 3-6)
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. 3-6)
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.
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. 3-8)
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.
IMPORTANT: Rapid movement of control levers is not recommended
as damage to the hydraulic system components may occur.
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. 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

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. Do not operate the mower
without either the discharge chute or the entire grass
collection system in place. Fig. 3-7
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.
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.
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!
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

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.
Deck cutting height adjustment
Deck height is adjustable from 1” - 5” (2.54 CM - 12.7 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. 3-9
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” (2.54 CM). When the height adjusting stop is placed
in the 1” (2.54 CM) hole, with the 1/4” (.64 CM) plate on the operator’s
side of the hole, the cutting height is at 1-1/4” (3.18 CM).
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
wheel

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 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 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 wheels up or down, in 1/2” (12.70MM) increments,
using the different axle mount holes in the wheel mount bracket. Fig. 3-10
When adjusting the rear anti-scalp wheels, the wheel should be in the
same axle mount hole as the front anti-scalp wheels.

MAINTENANCE & ADJUSTMENTS
Safe Servicing Practices
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. Place control levers in
the park brake position, disengage deck clutch, remove ignition
switch key and disconnect negative battery cable before doing any
maintenance. 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 and remove ignition switch key
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, 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 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 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 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
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!
▲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
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.

to ensure component performance.
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.
Read and observe safety precautions elsewhere in this
manual.
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.
The fuel tanks are located in the tractor’s fenders.
Use regular unleaded gasoline with an octane rating of 87 or higher.
IMPORTANT: Never use methanol, gasoline containing methanol, or
gasohol containing more than 10% ethanol because the fuel system could be
damaged. Do not mix oil with gasoline.
A fuel shut-off valve is located on each tractor. The location and
operation of the fuel valve will vary depending upon the unit. Close the
fuel valve to prevent fuel flow to the engine. The valve’s two other
positions will allow fuel to be drawn from either one or the other fuel tank.

IMPORTANT: Do not overfill the fuel tanks. The fuel tanks should
be filled no higher than 2” (5.08 CM) below the tank’s fill neck.
Engine oil and filter
Check engine oil daily and after every 4 hours of operation. 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.
Engine air filter
Perform engine air filter maintenance per the Service Interval chart

A specially designed dry filter is standard equipment on these tractors
and supplies clean combustion air to the engine. Fig. 4-5
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.

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.
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

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 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.
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.
Belts
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.
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.
