To the new owner

The purpose of this manual is to assist owners and
operators in maintaining and operating the Hustler Super Z
Diesel tractor and deck. Please read it carefully;
information and instructions furnished can help you achieve
years of dependable performance.

A separate Engine Manual is included with your owner’s
packet which contains additional engine information that
will not be repeated in this manual. You are urged to read it
before attempting any operation or repair of the engine.

The Quick Reference Decals, located under the right front
of the seat, the right front of the deck, and under the seat
pan, are designed to give the operator brief information
needed in the daily operation of the machine. These decals
are not intended to be used in place of this manual but
instead are to be used as an extension of this manual. These
decals should not be removed or obliterated. Replace these
decals if they become unreadable.

It is the owner’s responsibility to make certain that the
operator reads and understands this manual and the Quick
Reference Decals before operating this machine. It is also
the owner’s responsibility to make certain that the operator
is a qualified and physically able individual, properly
trained in the operation of this equipment. Local regulations
may restrict the age of the operator.

Using this manual

General operation, adjustment and maintenance guidance
is outlined for both the experienced and novice Hustler user.
Operating conditions vary considerably and cannot all be
addressed individually. Through experience, however,
operators should find no difficulty in developing good
operating skills suitable to most conditions.

Directions used in this manual, for example RIGHT or
LEFT, refer to directions when seated on tractor facing
forward, unless otherwise stated.

Photographs and illustrations used were current at the
time of printing, but subsequent production changes may
cause your machine to vary slightly in detail. Hustler Turf
Equipment reserves the right to redesign and change the
machine as deemed necessary, without notification. If a
change has been made to your machine which is not
reflected in this owner’s manual, or the parts manual, see
your Hustler dealer for current information and parts.

Warranty registration

The Delivery and Warranty Registration form must be
completed and signed to validate your warranty protection.
As the new equipment owner, you are expected to see that
the form is completed and forwarded to Hustler Turf
Equipment at time of delivery.

Be sure to register the tractor plus each attachment that
displays a model and serial identification number plate with
Hustler Turf Equipment.

IMPORTANT: Any unauthorized modification,
alteration, or use of non-approved attachments voids the
warranty and releases Hustler Turf Equipment from any
liability arising from subsequent use of this equipment.

Model and serial number

Tractor model and serial numbers are found on the serial
identification plate, located on the frame directly below and
to the left of the operator’s platform.

These numbers are required on the Warranty Registration
form. They will also assure you of the correct service parts
when replacement becomes necessary.

are available through your local Hustler dealer. To obtain
prompt, efficient service, always provide the following
information when ordering parts:

1. Correct part description

SAFETY PRECAUTIONS

▲

Never push forward suddenly on the steering control
levers while the machine is in rearward motion
because the machine may tip backward.

▲

When moving in reverse, push forward slowly on
levers and avoid sudden movement. Rapid movement
of the control levers in either direction could result in a
reaction of the tractor that can cause serious injury.

▲

Never operate a poorly maintained machine.

▲

Never carry passengers.

▲

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

▲

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

▲

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

▲

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

▲

Never refuel tractor while engine is running; never
refuel near an open flame or near devices which can
create a spark. Refuel outdoors preferably, or in well
ventilated areas.

▲

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

▲

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

▲

Never attempt to make any adjustments or repairs to
the tractor drive system, mower deck or any
attachment while the tractor engine is running or deck
clutch is engaged. Repairs or maintenance requiring
engine power should be performed by trained
personnel only.

▲

Never work under the machine or attachment unless it
is safely supported with stands, blocks or a hoist.

▲

Do not touch hot parts of machine.

▲

Never direct discharge of material from mower deck
towards bystanders. Do not operate the mower
without either the discharge chute or the entire grass
collection system in place.

▲

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

▲

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

▲

Turn off blades when not mowing.

▲

Slow down before turning.

▲

Stop the engine before removing the grass catcher or
unclogging the discharge chute. Never clear the
discharge chute with the engine running. Turn off the

cleaning. Use a stick to clear a plugged discharge area.

Never use your hand!

▲

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

▲

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

▲

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

▲

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

▲

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

▲

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

▲

Never make sudden starts, stops, turns, or reverse
direction, especially when maneuvering on slopes.
The steering is designed for sensitive response. Rapid
movement of the steering lever in either direction
could result in a reaction of the tractor that can cause
serious injury.

▲

If any attachment or additional weight is mounted on
the rear of the unit, any rapid movement of the control
levers in either direction could result in a reaction of
the tractor that can cause serious injury.

▲

Use extreme caution when operating on slopes.

• Be extremely careful changing directions on a slope.
Slow down.

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

▲

Do not remove or modify the stabilizer wheels.

▲

Remove obstacles such as rocks, tree limbs, etc.

▲

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

▲

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

▲

Do not turn on slopes unless necessary, and then, turn
slowly and gradually downhill, if possible.

▲

Do not mow near drop-offs, ditches, or embankments.
The machine could suddenly turn over if a wheel goes
over the edge of a cliff or ditch, or if an edge caves in.

▲

Do not mow on wet grass. Reduced traction could
cause sliding.

▲

Do not try to stabilize the machine by putting your foot
on the ground.

▲

Watch for holes, ruts or bumps. Uneven terrain could
overturn the machine. Tall grass can hide obstacles.

▲

Keep children out of the mowing area and under the
watchful care of another responsible adult.

▲

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

▲

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

▲

Never carry children, even with the blades off. They
may fall off and be seriously injured or interfere with
safe machine operation.

▲

Never allow children to operate the machine.

▲

Use care when approaching blind corners, shrubs,
trees, the end of a fence or other objects that may
obscure vision.

▲

Use extra caution when handling gasoline and other
fuels. They are flammable and vapors are explosive.

▲

Keep nuts and bolts tight, especially the blade

351254_041505

2-2

351254_041505

2-3

attachment bolts. Keep equipment in good condition.

▲

Never tamper with safety devices. Check their proper
operation regularly.

▲

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

▲

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

▲

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

▲

Do not remove or modify the stabilizer wheels.

▲

The Hustler mower is capable of operating
horizontally (traverse) on moderately steep slopes.
When operating on slopes up to 15 degrees, be aware
of any conditions that may cause the tractor drive tires
to lose traction resulting in a possible loss of control of
the machine. An operator should not operate on a
slope until he is thoroughly familiar with the
equipment.

Do not operate the machine on slopes greater than
15 degrees.

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

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

1. Wet terrain

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

washouts

3. Mounds of dirt

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

5. Grass type, density, and height

6. Extremely dry conditions of grass

7. Tire pressure

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

Another consideration to safe mowing on slopes is
to be aware of what is located at the bottom of the
slope. Extreme caution should be used when there is a
hazard located at the bottom of the slope. Some
examples are:

1. Water; i.e. lake, river

2. Cliffs, retaining walls

3. Roads, highways

4. Buildings

5. Rocks

These are just a few examples of situations when
caution must be used when operating on a slope.
There are many other possibilities too numerous to
mention. Just remember to always exercise extreme
caution when operating on any slope.

▲▲

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

▲▲

Specific safety warning decals are located on the
equipment near the immediate areas of potential
hazards. These decals should not be removed or
obliterated. Replace them if they become non-readable.

351254_041505

2-4

Do not smoke while refueling.
Do not fill tank with engine running,
or while the engine is hot.
Allow engine to cool before storing
machine inside a building.
Store away from open flame or spark
if there is fuel in tank.
Clean up any gasoline spills.
Do not refuel while in enclosed trailer
or other enclosed areas

Avoid skin contact with battery acid.
Always wear eye protection when
checking the battery, acid can cause
serious injury to skin and eyes. If
contact occurs, flush area with clean
water and call physician immediately.
Acid will also damage clothing.
Do not allow open flame near the
battery when charging.
Hydrogen gas forms inside the
battery. This gas is both toxic and
flammable and may cause an
explosion if exposed to flame.
Always remove the negative ground
first and replace it last.
Do not overfill battery.
Electrolyte may overflow and
damage paint, wiring or structure.
When cleaning the battery, use soap
and water. Be careful not to get
soap and water into the battery. Use
soda mixed in water to clean
corrosion off the terminals.

Hydraulic fluid escaping under
pressure can penetrate skin.
Hydraulic fluid may also cause
infection in a minor cut or opening in
the skin; if exposed to hydraulic fluid,
see a doctor at once.
Before applying pressure to hydraulic
system, make sure all connections
are tight and all hoses and lines are
in good condition.
Relieve all pressure in the system
before disconnecting or working on
hydraulic lines.
To find a leak under pressure, use a
piece of cardboard or wood – never
use your hands.
To relieve all pressure in system,
turn engine off and lower attachment.

Read Owner’s Manual and Quick

Reference Decal before attempting to

operate this machine.

The following illustrations show the various safety decals that are located on the machine. A brief explanation is shown to

help the operator understand the meanings of these decals.

Do not remove or modify stabilizer
wheels or injury can result.
Never stop suddenly while backing
down slopes. This action may result
in a reaction of the tractor that can
cause serious physical injury.

Never operate the mower deck with
side deflector removed or in raised
position, except when the grass
catcher attachment is being used.

Hot surface!

Keep shields or covers in place
while machine is in operation.
Keep hands away from rotating
pulleys and belts.

Whirling blades! Keep hands and
feet away.
Beware of thrown objects.

Avoid crushing
Do not jump if machine tips
Use seat belt
Seat belt must be fastened while
operating this machine. Failure to
use seat belt will result in serious
injury in the event of a roll over.

Use seat belt.

This structure’s protective capability
may be impaired by structural
damage, overturn, or alteration.
To minimize chance of injury or
death from rollover; keep ROPS in
the raised and locked position and
use the seat belt.
There is no roll over protection when
the ROPS is in the lowered position.
Lower the ROPS only when
absolutely necessary. Drive slowly
and carefully. Raise the ROPS as
soon as clearance permits. Read
and follow sloper operation
instructions and warnings.
Do no wear seat belt when the ROPS
is in the lowered position.

1. Hold this sheet of paper in front of you. Make sure that line A is horizontal.

2. Align line B with a verticle surface such as a pole, tree or building.

3. Fold the paper along the slope guide lines (C, D or E).

4. Align the closest slope guide line with the ground slope. This will give you a close estimation of the
ground slope to be mowed.

high temperatures can severely damage the engine.

10. Alternator warning light (Fig. 3-2) — this light

comes on when the ignition switch is placed in the
RUN position and stays lit until the engine is running
and the battery is being charged. If light comes on
during operation, shut engine off immediately, locate
and correct the problem.
If light remains on while engine is running, it indicates
the that the batteries are being discharged.

Safety interlock system

The tractor is equipped with a safety interlock system
consisting of the park brake switches, seat switch, and deck
clutch switch.

Check tractor safety start interlock system daily, prior to
operation. This system is an important tractor safety feature.
It should be repaired immediately if it malfunctions. The
machine incorporates a separate seat switch which will stop
the tractor engine when the operator is unseated for any
reason while the tractor is operating. This is a safety feature
designed to prevent runaway or accidental entanglement. To
inspect the system:

1. The operator must be on the seat when testing the seat

switch.

2. Set both control levers in the park brake position.

3. Start the engine and allow it to warm up to operating

temperature.

4. With the deck clutch switch down and the control

levers in the park brake position, slowly raise off of the
seat. The engine should continue to run.

5. With the deck clutch switch up and/or the control

levers in the neutral position, slowly raise off of the
seat. The engine should stop.

6. If the engine fails to stop when the deck clutch switch

is up or one or both of the control levers is up(out of
the park brake position) and the operator is off the seat,
check the function of the seat switch. If the seat switch
is not operating properly (is not opening or closing)
and if the cause can not be determined, replace the seat
switch.

If the problem can not be located, contact your Hustler

Dealer.

WARNING: The safety interlock system should
always function per steps 4 and 5. If it does not
function properly, it should be corrected
immediately. Do not operate machine without
properly functioning seat safety switch.

Engine starting

The Hustler Super Z Diesel safety start interlock system
is also designed to protect the operator and others from
accidental injury due to unintentional engine starting. The
engine starting motor will not engage until:

A. Control levers are in the park brake position.
B. Deck clutch switch is in the down (OFF) position.

WARNING: The safety interlock system must
not be disconnected or bypassed.

NOTE: The operator’s seat is equipped with a separate
safety switch. If for any reason the operator should become
unseated when the brake switches are disengaged or the
deck clutch switch is engaged the engine will stop.

The following steps are the correct procedures for
starting the engine. If difficulty is encountered, contact the
Hustler Dealer in your area.

1. Before starting tractor each day, perform daily pre-

operation checking.

2. Make sure the control levers are in the park brake

position and deck clutch switch is disengaged.

3. Set throttle at approximately 1/2 open position.

4. Insert key in ignition switch and rotate it to the ON

position, then hold the pre-heat switch down to pre­heat the engine, hold this position for 6 seconds. This
is necessary only when the temperature is below 50o F.
This operation is not necessary when restarting a warm
engine.
Shown in the chart are the standard preheating times
for various temperatures. This operation, however, is
not required when the engine is warmed up.

Failure to follow these recommendations can lead
to premature failure of the starter motor and the
fuel shut-off solenoid.
NOTICE: Ether, or other starting fluids, must
never be used as a starting aid with this engine.
Warranty will be denied when engine damage
results from such use.

5. Rotate ignition switch key full clockwise to engage

starting motor. Release key when engine starts.

IMPORTANT: The engine starter should not be
operated for periods longer than 30 seconds at a time. An
interval of at least two minutes should be allowed between
such cranking periods to protect the starter from overheating
and burn-out.

6. Perform test to make sure safety start interlock system

is operating properly. Refer to Safety start interlock
system section.

7. As soon as engine begins to run, check to make certain

the oil warning light is off. If not, stop engine
immediately and check for the cause.

8. Allow the engine to idle a few minutes before

advancing the throttle and/or engaging the deck clutch.

9. Before stopping the engine, place the control levers in

the park brake position, disengage the deck clutch, and
throttle back to low idle for a couple of minutes; then
rotate ignition key counter-clockwise to the OFF
position. Remove the key from switch before leaving
the tractor.

WARNING: Never leave the machine
unattended with key in ignition switch.

Bypass valve

Moving tractor with stalled engine

If it becomes necessary to move the tractor when the
engine is inoperative, the hydraulic pumps are equipped with
bypass valves. Before moving the unit, turn bypass valves
counter clockwise one-half to one revolution. The valve
stems on each hydraulic pump are located on the top of the
pump and are identified as a hex stud. Figure 3-8

Do not tow the machine. Move it by hand or use a winch
to load on a trailer for transporting.

When transporting on another vehicle, the tractor should
be facing forward and it must be secured.

IMPORTANT: Always make certain the two bypass
valves are returned to their operating position before running
the tractor following repairs.

ROPS

The two-post ROPS can be pivoted down so that the

machine can operate under low hanging tree limbs or other
obstructions. Do not wear the seat belt when the ROPS is in
the lowered position. Fig. 3-10

WARNING: To minimize chance of injury or
death from rollover: keep ROPS in the raised
and locked position and use the seat belt.
There is no roll over protection when the
ROPS is in the lowered position.
Lower the ROPS only when absolutely
necessary. Drive slowly and carefully. Raise
the ROPS as soon as clearance permits. Read
and follow slope operation instructions and
warnings.
Do not wear seat belt when the ROPS is in the
lowered position.

Driving the tractor

DANGER: Never make sudden starts, stops or

reverse direction, especially when going up a
slope because the mower may tip backwards.
The steering is designed for sensitive response.
Rapid movement of the control levers in either
direction could result in a reaction of the tractor
that can cause serious injury.

After starting engine, engage the control levers and steer

as follows:

To go forward, push control levers forward an equal

distance (Fig. 3-9).

To go in reverse, pull control levers rearward an equal

distance (Fig. 3-9).

To turn left, move the right control lever farther forward

from neutral than the left control lever.(Fig. 3-9)

To turn right, move the left control lever farther forward

from neutral than the right control lever. (Fig. 3-9)

To pivot turn, move one control lever forward and the

other control lever back of neutral. This will allow the drive
wheels to counter-rotate. (Fig. 3-9)

To stop or decrease speed, move control levers to

neutral. When going forward pull back gently on control
levers. When going in reverse push forward gently on
control levers.

DANGER: When moving in the rearward
direction push forward gently on control levers
and avoid sudden movement. Any sudden
movement could cause the front of the mower to
come off of the ground resulting in possible loss
of control.

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

To increase speed, increase control lever’s distance from

neutral. The farther forward control levers are from neutral,
the faster tractor will travel forward. The farther back
control levers are from neutral, the faster tractor will go in
reverse.

Operating suggestions

DANGER: Prior to operating the tractor the

operator should be thoroughly familiar with the
proper use and operation of the equipment,
should read the manual completely and
thoroughly, and should have attempted slow
moving maneuvers to become familiar with the
operation of the equipment before attempting
normal speed operation. An inexperienced
operator should not mow on slopes or on uneven
terrain.

WARNING: If you lose steering control while
operating the machine, place the steering
control levers in the park brake position
immediately. Inspect the machine and involve
your Hustler dealer to resolve the problem
before continuing to operate.

WARNING: The unit’s control levers are very
responsive: Easy does it! For smooth operation,
move lever slowly, avoid sudden movement.
Skill and ease of operation come with practice
and experience.

WARNING: Children or bystanders may be
injured if they move or attempt to operate the
tractor while it is unattended. Always disengage
deck clutch, place control levers in park brake
position, stop tractor engine, and remove ignition
key when leaving operator’s seat.

Inexperienced operators may have a tendency to
oversteer and lose control. Slow-moving practice
maneuvers are recommended to become familiar with these
characteristics before attempting normal speed operation.

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

When turning on soft wet turf, keep both wheels rolling
either forward or backward. Pivoting on one stopped wheel
can damage turf. This is especially important when
mowing.

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

WARNING: Do not operate the equipment
while wearing sandals, tennis shoes, sneakers,
shorts or any type of loose fitting clothing.
Always wear long pants, safety glasses, hearing
protection and safety shoes when operating this
machine.

Keep blades sharp. Many professional mowing
companies have additional sets of blades and change blades
twice a day: once in the morning and again at noon. Many

problems with incorrect cutting patterns are due to dull
blades or blades which have been sharpened incorrectly.

Information on sharpening blades is listed in this manual’s
maintenance section. In addition, most communities have
individuals or companies which specialize in sharpening
mower blades. Blade sharpness should be checked daily.

Use high blade speed. Your Hustler Super Z Diesel is
designed to operate at full throttle. The throttle setting
directly controls blade speed. The highest blade speed
generally gives best cut.

Direct grass discharge to right, away from unmown

351254_041505

3-5

Figure 3-11

Side

discharge

chute

area. Select a mowing pattern that directs grass discharge
towards the outside, not towards center, of mowing area.
Generally, this means using a pattern utilizing left turns
because side discharge (Fig. 3-11) is to right. In any case,
avoid throwing grass discharge onto unmowed area because
grass is then mowed “twice”. Mowing twice puts an
unnecessary load on the unit and reduces mowing efficiency.

When mowing a lawn for the first time cut grass

slightly longer than normal to avoid scalping uneven terrain.
When possible, it is best to use the cutting height that was
used in the past. When cutting grass taller than six inches,
you may want to mow the lawn twice to achieve a better
quality of cut.

During normal mowing cut only about 1/3 of the grass

blade. Cutting more than that is not recommended unless

grass is sparse or it is the end of the mowing season.

Alternate mowing direction to keep the grass growing

straight and better dispersion of the clippings.

Remember, grass grows at different rates at different

time of the year. Mow more often in the early spring to
maintain the same cutting height. As the growth rate slows
in mid summer, mow less frequently. If you cannot mow at
a regular interval, mow at a high cutting height; then mow
again two days later at a lower cutting height.

Raise the cutting height of the mower if the cutting

width of the mower is wider than the previous mower. This
ensures that uneven turf is not cut too short.

Raise the cutting height of the mower if the grass if

slightly taller than normal or if it contains a high degree of
moisture. Then mow it again with the cutting height set
lower.

If the machine’s forward motion must be stopped while

mowing, a clump of grass clippings may drop onto your
lawn. To avoid this, move onto a previously cut area with
the blades engaged.

WARNING: Never direct discharge of material
from mower deck towards bystanders.

WARNING: Never operate the mower deck
with discharge chute removed or in raised
position.

WARNING: Always check area to be mown for
rocks and other debris before mowing.

Mower deck operation

DANGER: Never attempt to make any

adjustments to the mower deck while the engine
is running or with the deck drive clutch engaged.
Mower blades cannot be seen and are located
very close to deck housing. Fingers and toes can
be cut off instantly.

With the engine running, engage the deck clutch switch

(Fig. 3-2) and advance engine throttle to full rpm.

NOTE: Engaging the deck clutch at high engine rpm or
when under heavy load (in tall grass for example) can cause
belts and/or electric clutch to slip, resulting in premature
wear or possible damage.

Introduction

WARNING: Unless specifically required, DO

NOT have engine running when servicing or
making adjustments to tractor. Place control
levers in the park brake position, disengage deck
clutch, and remove ignition switch key. Repairs
or maintenance requiring engine power should be
performed by trained personnel only. To prevent
carbon monoxide poisoning, be sure proper
ventilation is available when engine must be
operated in an enclosed area. Read and observe
safety warnings in front of manual.

DANGER: Before working on or under the
deck, make certain engine cannot be accidentally
started. Shut engine off and remove ignition

switch key for maximum safety. Repairs or
maintenance requiring engine power should be
performed by trained personnel only.

DANGER: Exercise caution when working
under the deck as the mower blades are
extremely sharp. Wearing gloves is advisable
when working around or with the blades.

WARNING: Except when changing or checking
belt, always keep belt covers on mower for
safety as well as cleanliness.

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

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

WARNING: Keep your machine clean and
remove any deposits of trash and clippings,
which can cause engine fires and hydraulic
overheating as well as excessive belt wear.

Clear away heavy build-up of grease, oil and dirt,
especially in the engine and hydraulic reservoir area; minute
dust particle are abrasive to close-tolerance engine and
hydraulic assemblies.

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

To do this it will be necessary to raise and block the deck
in the full up position and scrape the build-up from
underneath.

WARNING: When possible clean under mower,
using a stick or similar instrument making sure
that no part of the body, especially arms and
hands are under mower.

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

Blade spindle bolt top........................65-75......88.14-101.7

Blade spindle bolt bottom.....................118 ................160.0

It is recommended that these be checked after the first 2
hours of operation, initially and every 50 hours following
removal for repair or replacement.

For all other torques refer to the tractor parts manual for
standard torque chart.

For engine torque values, see engine owner’s manual.

Tires

It is important for level mowing that the tires have the
same amount of air pressure. The recommended pressure
are:

Drive wheels............................8-10psi (55-69

KPa)

Gauge wheels..........................8-10 psi (55-69 KPa)

Solid fill tires are not recommended for Hustler turf
equipment. On any machine, with solid filled tires, the
warranty claim will be denied.

WARNING: Explosive separation of a tire and
rim can cause serious injury or death.
Do not attempt to mount a tire without the proper
equipment and experience to perform the task.
Always maintain the correct tire pressure and
never over inflate.
Never weld or heat a wheel and tire assembly as
an explosion may occur. Welding can weaken or
deform a wheel.
When inflating tires stand to one side and not in
front of or over the tire assembly.
Check tires for low pressure, blemishes, damaged
rims or missing lug bolts and nuts.

Hour meter

To recognize when your machine needs servicing, check
the hour meter and the maintenance schedule. The hour
meter shows the number of hours the engine has run and the
maintenance schedule lists the service intervals. Fig. 4-2

Lubrication

Grease the following areas per the Maintenance

Schedule. Use SAE multi-purpose grease.

1. Front gauge wheel bearings

2. Four deck lift pivots, located to the side of the

operator’s footrest

3. Deck idler

4. Pump idler pivot

5. Two deck pusher arm pivots

6. Blade spindle assemblies The spindle assemblies

require lubrication annually. Each spindle shaft is
equipped with a grease zerk located under the deck.
Use no more than one or two ounces of SAE multi­purpose grease, (1 to 2 pumps on an average grease
gun). Do not force lubricant in to grease zerks.
Bearings are sealed and do not require much
lubricant.

Electrical system

The electrical system is a 12 volt, negative ground.
Recommended battery size is a garden tractor BCI group
U1R with 225 or better cranking AMP rating. Two
maintenance-free batteries are recommended. Otherwise,
follow battery manufacturer’s maintenance, safety, storing
and charging specifications.

The batteries are located under the seat. Fig. 4-3

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

WARNING: Avoid skin contact with battery
acid.
Always wear eye protection when checking the
battery, acid can cause serious injury to skin and
eyes. If contact occurs, flush area with clean
water and call physician immediately. Acid will
also damage clothing.
Do not allow open flame near the battery when
charging.
Hydrogen gas forms inside the battery. This gas
is both toxic and flammable and may cause an
explosion if exposed to flame. Always remove
the negative ground first and replace it last.
Do not overfill battery.
Electrolyte may overflow and damage paint,
wiring or structure. When cleaning the battery,
use soap and water. Be careful not to get soap
and water into the battery. Use soda mixed in
water to clean corrosion off the terminals.

Figure 4-2

Hour

meter

WARNING: Shorts caused by battery terminals

or metal tools touching metal tractor components
can cause sparks. Sparks can cause a battery gas
explosion which will result in personal injury.
Prevent the battery terminals from touching any
metal tractor parts when removing or installing
the battery.
Do not allow metal tools to short between the
battery terminals and metal tractor parts.

WARNING: Incorrect battery cable routing
could cause damage to the tractor and battery
cables. This can cause sparks which can cause a
battery gas explosion which will result in
personal injury.
Always disconnect the negative (black) battery
cable before disconnecting the positive (red)
cable.

Common circuit failures are usually caused by shorting,
corroded or dirty terminals; loose connections, defective
wire insulation or broken wires. Switches, solenoids and
ignition components may also fail, causing a shorted or open
circuit.

Before attempting any failure diagnosis of the electrical
system, use a test light or voltmeter to check the battery
voltage. If the battery voltage is satisfactory, check the
cleanliness and tightness of the terminals and ground
connections. A general understanding of electrical servicing
and use of basic test equipment is necessary for
troubleshooting and repair.

Major overhaul or repair of the starting motor or
alternator should be performed by trained technicians only.

Access to engine and hydraulic
pumps

The hydraulic pumps are accessed by lifting the seat

platform. The seat platform is hinged at the front. To raise
it, release seat latch and tilt seat platform up and forward.
The seat platform catch (Fig. 4-4) will prevent the seat from
going all the way over. However, if more access is desired
under the seat platform, the seat platform catch can be raised
allowing the seat to pivot more. Make certain to place the

control arms in the park brake position and pivot the
arm rests upward before placing the seat platform in the
full forward position to prevent arm rest damage.

The engine can be accessed from the rear of the machine
without removing the engine shroud. If additional access is
required, remove the engine shroud.

WARNING: Always wear adequate eye
protection when servicing the hydraulic system
and battery.

Hydraulic system

IMPORTANT: Never use hydraulic or automatic

transmission fluid in this system; use only motor oil as
specified. Remember, dirt is the primary enemy of any
hydraulic system.

WARNING: Hydraulic oil escaping under
pressure can penetrate skin. Hydraulic oil may

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

The 3.0 U.S. gallon (11.4 liter) hydraulic reservoir is part
of the radiator housing. The fill neck is the left neck on the
top of the radiator housing. Fig. 4-5

Check oil level in hydraulic system after every 50 hours
of operation or weekly, whichever occurs first. Check more
often if system appears to be leaking or otherwise
malfunctioning.

Fluid level should be 3” (7.62

CM) from the top of fill

neck. Use only SAE 10W40 SG, SF/CC, CD service motor
oil.

Change hydraulic system filter element (Fig. 4-6) after
first 50 hours of tractor operation, then replace filter and oil
in reservoir every 500 hours thereafter.

The system filter is located next to the left drive wheel on
the tractor frame. A standard oil filter wrench is used to
change filter, threads are right handed. Use a Hustler

approved filter element only.

IMPORTANT: Prefill the filter element with clean oil,
before installing, to prevent drawing air into the system

pump.

NOTE: Install new hydraulic filter element immediately
after the removal of the old filter to minimize oil loss from
reservoir.

1. Fill the filter element with clean system oil. Smear a

light coating of oil on upper surface of rubber seal.

2. Install the filter element on base. Tighten the oil filter

by hand until the filter seal makes contact with the
filter head, then tighten an additional 3/4 - 1 turn with
an oil filter wrench. — DO NOT OVERTIGHTEN.

3. Start tractor engine and let run at approximately 2/3

throttle for a few minutes to work any trapped air out
of the system before engaging the steering control
lever.

4. Stop the engine and check the filter and connections

for leaks.

5. Check the hydraulic reservoir for specified oil level.

Add clean oil as necessary.

Clean or replace hydraulic reservoir cap annually. Cap
may be cleaned by dipping in or flushing with cleaning
solvent. Follow manufacturer’s instructions and warnings
for application of solvent type selected.

NOTE: The hydraulic pumps are equipped with bypass
valves. For more information refer to Operation section,
Moving tractor with stalled engine.

A hydraulic oil heat exchanger is installed on the Super Z
Diesel. This heat exchanger is designed to keep hydraulic
system oil temperature lower in hot operating conditions or

heavy continuous operating conditions.

This hydraulic heat exchanger is part of the radiator
housing. The air is drawn across the cooling fins by the left
electric fan located to the rear of the radiator housing. Fig.
4-6

NOTE: The electric fans will perform a test cycle where
they will push the air and then will auto reverse and pull air
before reversing and pushing the air.

The deck blades are powered by a hydraulic motor. This
motor provides power to the deck spindle drive belt. Fig. 4­7

Fuel system

WARNING: Observe usual fuel handling

precautions; do not smoke while refueling, do not
fill tank with engine running or while engine is
hot; allow engine to cool before storing machine
inside a building, keep fuel away from open
flame or spark and store machine away from
open flame or spark if there is fuel in the tank.
Read and observe safety precautions at front of
this manual.

WARNING: Fuel System Under Pressure! The
fuel system operates under high pressure, and the
fuel filter and fuel line used must be approved
system components only. Use of substitute parts
can result in system failure, fuel leakage and
possible explosion.

The fuel tanks are located in the tractor’s fenders. (Fig.
4-8) Total capacity for the fuel tanks is 18 U.S. gallon (68.1
liter)

This engine requires number 2 diesel fuel only. The fuel
filter is located on the left, rear side of the engine. Change
filter after every 100 hours of operation or annually,

whichever occurs first. Fig. 4-9

When replacing the fuel filter, check the fuel line hoses

for any cracks or leaks. Replace as needed.

Super Z Diesel tractors are equipped with a fuel shutoff
valve located to the right rear of the seat (Fig. 4-10). Rotate
the valve to the middle position (shown) to allow fuel to

flow from the right fuel tank to the fuel pump. The right
position prevents fuel flow to the fuel pump. The left
position allows fuel to flow from the left fuel tank to the fuel
pump. Close this valve to prevent fuel flow to the engine
when servicing the fuel system or when transporting the unit
on a trailer or truck.

Diesel engines are subject to air blockage whenever the
fuel tank runs empty, the fuel filter has been removed, any
fuel lines have been disconnected or removed and replaced,
or when the tractor has been stored for a period of time.
Should such air blockage occur, it will be necessary to bleed
the system, removing any trapped air between the fuel tank
and filter, then trapped air between the filter and injector
pump as follows:

1. Fill the tank with fresh fuel and make sure the shut-off

valve is open at tank.

2. Loosen the vent screw (Fig. 4-9) located on top of the

fuel filter and leave it open until air bubbles are no
longer present, then close the vent screw.

3. Start the engine and run at low rpm for 15 to 30

seconds to expel air from pump, then close the air vent
screw.

4. If engine fails to start, repeat steps 2, 3 and 4.

Engine oil and filter

Check engine oil daily and after every 4 hours of

operation. Crankcase dipstick and oil filler location are

located on top and rear of the engine (Fig. 4-11). Tractor
must be setting level when checking oil. Refer to engine

manual and maintenance schedule for oil
recommendation and capacities.

Change the engine oil and filter after the first 5 hours of
operation, per the engine manufacturer’s recommendations
after that. If tractor is being operated in extremely dirty
conditions, then it is recommended oil be changed more
frequently.

The oil drain and oil filter are located at the lower rear of
the engine. Fig. 4-12

Engine air filter

Perform engine air filter maintenance per the Service
Interval chart on page 4-2.

A specially designed dry filter is standard equipment on
the Super Z Diesel tractors and supplies clean combustion
air to the engine. Fig. 4-13

Air service indicator

The Super Z Diesel has an air service indicator installed
in the air cleaner. Fig. 4-13 & 4-14

Replace the element whenever the service indicator
reaches the change filter red line. Check the indicator daily
and replace element as needed or annually whichever occurs
first.

Reset the indicator by pushing in on the yellow button
after each element change. Fig. 4-14

A service indicator takes the guesswork out of air cleaner
servicing and allows you to safely benefit from the filter’s
optimum performance.

Safety filter

The Super Z Diesel is equipped with a safety filter. The
filter element slides over the safety filter. Use Hustler part
number 785279 only when replacing the safety filter.

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

Recommended service procedure

Many engine failures can be attributed to improper air
cleaner servicing. Ingested dust and dirt will cause cylinder,

piston and bearing damage in a few hours. “Dusted”
engines will result from:

1. Overservicing the air filter element.

2. Improper installation.

3. Damaged filter, seals or canister.

4. Incorrect air filter element size.

5. Use of poorly designed aftermarket air filter elements.

Air cleaner servicing is an inexpensive maintenance
check that can prevent costly non-warrantable premature
engine damage.

Overservicing

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

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

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

It is important to note that whenever an air filter element
is cleaned by any method, the person or company
performing the cleaning assumes responsibility for the
integrity of the filter from then on. The Donaldson

warranty for air filters expires upon cleaning or
servicing in any manner because the condition of the
filter after servicing is completely out of their control.
Therefore, on a dust ingested engine failure, there will be
no warranty consideration if the air filter element has
been cleaned or serviced in any manner.

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

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

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

Improper installation of an air filter element

Dust must not leak past the seals on each end of the air
filter element. The filter must be aligned within the canister
and properly seated for an effective seal so that no dirt can
enter the engine.

Damaged filter, seals or canister

Never bang or bump the filter element against the tire or
any solid object, as dust and dirt particles will be forced
through the media causing continual passing of dirt into the
engine. Visually inspect the outside of the air cleaner
canister periodically for external damage and replace if
necessary.

Cooling system

Engine cooling is accomplished with circulated water and
Ethylene Glycol mixture. The radiator is equipped with a
pressure cap and recovery tank. System capacity is
approximately 3.0 U.S. gallon (11.36 liter). A 50-50
mixture is recommended for all season operation. This
mixture provides freeze protection to -32 degrees F (-35
degrees C). Should temperatures fall below this level,
additional Ethylene Glycol must be added to the mixture.

Visually inspect the system daily prior to operating
tractor. Check coolant level in the recovery tank located to
the front left of the radiator assembly (Fig. 4-15). When the
engine is cold there should be 1” (2.54 CM) of coolant in the
recovery tank. When adding coolant, pre-mix the solution
before adding it to the recovery tank. It is not necessary to
remove radiator cap for adding small amounts of coolant to
system.

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

The system should be drained, flushed and refilled with
fresh solution after every 500 hours of operation.

If frequent refilling is necessary or if coolant appears

Incorrect air cleaner element

Use only the correct Donaldson air filter element, Hustler
part number 785261, which is designed to fit the canister
properly.

Hustler air filter elements have the correct media
composition, filter area, micron size and dimensions.
Always use genuine Hustler filters. Many aftermarket
filters have been found to be incompatible with Hustler’s
canisters and engines.

The air filter must remain intact to block passage of dirt
and foreign particles from entering the engine. Being
inclined to disbelieve the need for more expensive air filter
elements used on diesel engines may cause some individuals
to opt for a less expensive part.

The filter element must be sufficient size and
construction to withstand stresses, caused by rapid cycling
of the air volume demanded by the engine, without cracking
or tearing under fatigue and pressure (especially diesel
engines). Therefore, Hustler Turf Equipment and the engine
manufacturers have carefully selected a reliable filter
designed to fit the needs of the engines. The filter specified
is a Donaldson filter, Hustler part number 785261.

Owners should be reminded that failure to use original
equipment replacement parts is an “alteration” and will not
be considered for warranty in the event of engine damage.

Recommended service procedure

1. Release clamps and remove element. Clean the

canister with a damp cloth.

2. Before installing a new element, inspect it by placing a

bright light inside and rotate the element slowly,
looking for any holes or tears in the paper. Also check
gaskets for cuts or tears. Do not attempt to use a
damaged element which will allow abrasive particles
to enter the engine.

3. Reinstall the dust cup. Make sure it seals all the way

around the air cleaner body, then tighten the clamps.

4. Check all fittings and clamps periodically for tightness

and inspect hoses for holes or cracks.

5. Periodically check the intake hose for signs of ingested

dust. Locate and repair the source of ingested dirt.

6. Never operate a machine without an air filter installed.

rusty, thoroughly check the system. Refer to the engine
manual for information on checking and cleaning system.

The air is pushed across the radiator cooling fins by the
right electric fan located at the rear of the radiator housing.
Keep the radiator and hydraulic heat exchanger area clean at
all times and make sure trash is not allowed to accumulate,
nor allow the fins and cores to become plugged.

NOTE: The electric fans will perform a test cycle where
they will push the air and then will auto reverse and pull air
before reversing and pushing the air.

Never force anything into the radiator fins which may

bend or distort them. For cleaning, use compressed air only.

General engine maintenance

Detailed instructions and recommendations for break-in
and regular maintenance are specified in the Engine
Owner’s manual. Please refer to this manual for engine
servicing, lubricating oil levels with quality and viscosity
recommendations, bolt torques, etc. The engine warranty is
backed by the manufacturer. Special attention should be
paid to applicable data which will not be duplicated here.

IMPORTANT: Refer to the Caterpillar engine owner’s

manual for specific cleaning instructions.

Belt replacement

Figures 4-17, 4-18 and 4-19 show diagrams and

descriptions of the unit’s belt drive systems.

Inspect these belts frequently for wear and serviceability.
Replace a belt that shows signs of severe cuts, tears,
separation, weather checking and cracking, or burns caused
by slipping. Slight raveling of belt covering does not
indicate failure, trim ravelings with a sharp knife.

WARNING: If the pump belt fails, loss of
control will occur especially when operating on a
slope. If you lose steering control while

operating the machine, place the steering
control levers in the park brake position
immediately. Inspect the machine and involve
your Hustler dealer to resolve the problem
before continuing to operate.

Inspect the belt pulley grooves and flanges for wear. A
new belt, or one in good condition, should never run against
the bottom of the groove. Replace the pulley when this is
the case, otherwise belt will lose power and slip excessively.

Never pry a belt to get it on a pulley as this will cut or
damage the fibers of the belt covering.

Keep oil and grease away from belts, and never use belt
dressings. Any of these will destroy the belt composition in
a very short time.

Mower blade maintenance

Check the mower blades daily, they are the key to power
efficiency and well groomed turf. Keep them sharp, a dull
blade will tear rather than cut the grass, leaving a brown
ragged top on the grass within a few hours. A dull blade
also requires more power from the engine.

Replace any blade which is bent, cracked or broken.

WARNING: Never attempt to straighten a bent
blade by heating, or weld a cracked or broken
blade as the blade may break and cause serious
injury.

DANGER: Never work with blades while
engine is running or deck clutch is engaged.
Always place deck clutch in the disengaged
position, place steering control levers in the park

brake position and turn engine off. Block up
mower when you must work under it. Wear
gloves when handling blades. Always check for
blade damage if mower strikes rocks, branches
or other foreign object during mowing!

Mower blade removal

Use a 15/16" wrench to remove the 5/8" cap screw

holding the blade to the spindle shaft from underneath.

Sharpen the blades on a grinder following pattern as
shown (Fig. 4-20). Touch-up sharpening can be done with a
file.

Check the blades for balance following grinding. A
commercial balancing tool is available through most
hardware supply stores, or balancing can be done by placing
the blade on an inverted line punch or 1/2" bolt. Blade
should not lean or tilt. Spin the blade slowly, blade should
not wobble. If blade is out of balance, true it up before
reinstalling.

Lay the blade on a flat surface and check for distortion
(Fig. 4-21 and 4-22). Replace any distorted blade.

Do not re-use spindle bolts which have stripped, worn or
undercut threads. Torque bolts on spindles to 118 foot­pounds (160.0

Nm) when reinstalling blades.

WARNING: When mounting blades, rotate
them after installation to ensure blade tips do not
touch each other or sides of the mower.

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

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

ADJUSTMENTS

Introduction

WARNING: Unless specifically required, DO

NOT have engine running when servicing or
making adjustments to tractor. Place control
levers in the park brake position and remove
ignition switch key. Repairs or maintenance
requiring engine power should be performed by
trained personnel only. To prevent carbon
monoxide poisoning, be sure proper ventilation
is available when engine must be operated in an
enclosed area. Read and observe safety warnings
in front of manual.

Your Super Z Diesel was adjusted before it left the
factory and was checked during predelivery setup.
However, after start-up and break-in some adjustments
could change.

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

WARNING: Keep your machine clean and
remove heavy deposits of trash and clippings,
they can cause engine fires and hydraulic
overheating as well as excessive belt wear.

Clear away heavy build-up of grease, oil and dirt,
especially in the area of reservoir oil and engine combustion
air; minute dust particle are abrasive to close-tolerance
engine and hydraulic assemblies.

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

Torque values

WARNING: Particular attention must be given

to tightening the drive wheel lug nuts, wheel
motor nuts, and blade spindle bolts. Failure to
correctly torque these items may result in the
loss of a wheel or blade, which can cause serious
damage or personal injury.

Torque values given below:

Ft-lbs. Nm

Wheel (lug) nuts ................................65-75......88.14-101.7

Wheel motor nut ...........................350-375 .....474.6-508.5

Blade spindle bolt top........................65-75......88.14-101.7

Blade spindle bolt bottom ....................118 ................160.0

It is recommended that these be checked after the first 2
hours of operation, initially and every 50 hours following
removal for repair or replacement.

For engine torque values, see engine owner’s manual.
For all other torques refer to the parts manual for

standard torque chart.

Steering linkage

The neutral adjustment for the control levers in the neutral

position is discussed in this section.

The tractor steering has been factory adjusted to eliminate
creeping when the control levers are in the neutral position
(Fig. 5-1). However, should the tractor begin to creep, the
control lever linkage can be adjusted as follows:

Control Lever Neutral Adjustment

Before considering any adjustment, check the tire air
pressure and make certain hydraulic system oil is at
operating temperature. Unequal tire pressure will cause the
tractor to drift to one side. Refer to tire pressure information
in the Maintenance section of this manual.

Fine adjustment to the unit’s steering is made with the
adjustable pump linkage rods located between the control
lever and pump arms. Fig. 5-2

Neutral is properly adjusted when the control levers are in
the neutral position and the drive wheels are not turning.

If the tractor creeps in the neutral position the control
linkage may be adjusted as follows:

1. Raise and block the tractor up so the drive wheels are

off of the floor.

WARNING: Make certain machine is secure
when it is raised and placed on the jack stands.
The jack stands should not allow the machine to
move when the engine is running and the drive
wheels are rotating. Use only certified jack

stands.

2. Position the control lever in the neutral position.

Disengage the deck clutch.

3. Disconnect the park brake linkage by removing the

bolt and nut from the turnbuckle. This must be done
on both the right and left sides. This linkage is located
below the tractor frame just in front of the drive tires.
Fig. 5-3

4. Start the engine and observe which way the wheels are

rotating.

5. If wheel(s) are rotating forward, loosen the jam nuts on

the pump linkage rods and rotate the rod to lengthen
the steering control linkage until the wheel(s) come to
a stop. Fig. 5-2
NOTE: The left linkage controls the left drive wheel
and the right linkage controls the right drive wheel .
Repeat for the opposite side if necessary.

6. If wheel(s) are rotating in reverse then loosen the jam

nuts on the pump linkage rods and rotate the rod to
shorten the steering control linkage until the wheel(s)
come to a stop. Fig. 5-2
NOTE: The left linkage controls the left drive wheel
and the right linkage controls the right drive wheel .
Repeat for the opposite side if necessary.

7. When both wheels remain in neutral, tighten the jam

nuts to lock the turnbuckle in place.

8. Test again by moving the control levers forward and

backward before returning them to the neutral position.
If the tires are in neutral, the unit is now ready for
operation.

9. After adjusting for neutral it may be necessary to re-

adjust the control lever stop. Fig. 5-4

10. Re-connect the park brake linkage bolt and torque to

33 ft.-lbs (44.75 N

m). Fig. 5-3

11. Remove the tractor from the jack stands.

WARNING: Be sure to reconnect the brake
linkage before operating tractor.

Control lever stops

The control lever stops (Fig. 5-4) are designed to do two
things: First, and most important, they must keep the pumps
from bottoming out internally. Secondly, the stops may be
adjusted to help drive straight when the control levers are
pushed forward against the stops.

To keep the pumps from bottoming out internally use the
following procedure:

1. To make the first adjustment the tractor engine must

NOT be running.

2. Check to make sure the control levers are against the

stops before the pumps are bottomed out internally.
To do this, gently and slowly move the control levers
forward and feel if there is some resistance on the
pump lever before the control levers hit the stops.
Check one side at a time. If you sense that the pump
arms are stopping the forward motion of the control
arms, loosen the jam nut on the adjustable stop of the
corresponding side and turn the stop (set screw) inward
to stop the control levers slightly before the pump
bottoms out. Lock in place when the adjustment is
correct by re-tightening the jam nut.

3. Do this for each side.

To adjust the stops for driving straight when control levers
are against the stops during operation:

1. Determine which drive tire is rotating too fast when

both control levers are against the stops. Then stop the
tractor and loosen the lock nut on the side which is
rotating too fast and turn the stop (set screw) inward to

stop the control lever sooner. Tighten the lock nut on
the stop and test again. Repeat this procedure until
unit drives straight.

NOTE: Since this is a hydrostatic drive, variables such as
temperature of oil, efficiency of pumps and motors, tire
pressure etc. may effect the consistency of the ability to rely
on the stops to drive straight without the operator making
minor steering adjustments with the control arms.

Steering dampener

The steering dampener (Fig. 5-5) is spring loaded to return
the control levers to the neutral position from the reverse
position. This gives the operator a sense of neutral during
operation.

To set the steering dampeners in the correct operating
position follow these steps:

1. Place the control lever in the neutral position.

2. Loosen the steering dampener’s front ball stud.

3. Compress the dampener spring housing pass the point

that the internal spring is engaged.

4. Release the dampener spring housing and allow the

internal spring to bring the housing back to the neutral
position.

5. Tighten the nut on the steering dampener’s front ball

stud.

Control lever adjustment

The control levers can be adjusted for operator comfort.
By loosening the cap screws that attaches the upper control
lever to the lower lever (Fig. 5-6), the upper control lever
can be pivoted to fit the operator’s personal preference.

The control levers should be adjusted so that they align
with each other when in the neutral position.

Park brake adjustment

Occasionally check the park brakes and adjustment using
the following method:

1. Move the control lever to where it is 1/2” (1.27

CM)

inside the park brake slot. Fig. 5-9
NOTE: When the control lever is against the outside
edge of the the slot, the brakes should not be engaged.

2. Hold the control lever in this position. Rotate the

brake linkage to shorten it until the brake acutator
lever is rotated forward as far as it will go. Re-tighten

the jam nuts until they are tight against the turnbuckle.
NOTE: It may be necessary to loosen the jam nuts
before turning the brake linkage.

3. Repeat steps 1 thru 2 for the other side.

4. The brakes should now be set.

Hydraulic pump belt adjustment

The pump belt belt tension remains constant by means of
a tension idler and spring (Fig. 5-11). The spring tension
should be such that the belt does not slip under normal
operating load conditions, assuming the belt is not
excessively worn or damaged. As belt stretches and wears,
adjustment may become necessary. To increase belt tension,
move the spring chain one (or more) link(s) at the anchor
bracket (Fig. 5-11). Installed spring length should be 9.0" ±
.3" (22.8 cm ± .76 cm) originally with adjustments of .60"
(15.2mm) per chain link. (Fig. 5-13)

IMPORTANT: Do not over tension the spring to
compensate for a badly worn belt or pulley.

NOTE: Replace the belt every 400 hours or every two
(2) years whichever comes first.

WARNING: If the pump belt fails, loss of
control will occur especially when operating on a
slope. If you lose steering control while

operating the machine, place the steering
control levers in the park brake position
immediately. Inspect the machine and involve
your Hustler dealer to resolve the problem
before continuing to operate.

Deck drive belt adjustment

The spindle belt tension remains constant by means of a
tension idler and spring (Fig. 5-12). The spring tension
should be such that the belt does not slip under normal
operating load conditions, assuming the belt is not
excessively worn or damaged. As belt stretches and wears,
adjustment may become necessary. To increase belt tension,
move the spring chain one (or more) link(s) at the anchor
bracket (Fig. 5-12). Installed spring length should be 9.0" ±
.3" (22.8 cm ± .76 cm) originally with adjustments of .60"
(15.2mm) per chain link. (Fig. 5-13)

IMPORTANT: Do not over tension the spring to
compensate for a badly worn belt or pulley.

Engine RPM setting

The Super Z Diesel is designed so that the engine will run
at the following settings:

High idle - 3100 ±50 rpm At this speed the hydraulic
pumps are running at their maximum rated speed.
Low idle - 1200 ±50 rpm

Deck leveling and height adjustment

The mower deck has three areas that may need to be
checked and adjusted periodically. Before considering any
mower deck leveling adjustments, check that the tire air
pressure is within the specified range.

Deck level adjustments

Leveling the deck must be done in the following manner

and order:

1. Check tire pressures to make certain they are properly

inflated before starting to level deck. The
recommended pressures are as follows:

Drive wheels tire pressure .......8-10 psi (55-69

KPa)

Gauge wheels tire pressure......8-10 psi (55-69 KPa)

WARNING: Stop engine. Make sure deck
clutch switch is in the down (OFF) position.
Place control levers in the brake position before
leaving machine.

2. Park the unit on a flat surface.

3. Raise deck and place 3" (7.62

CM) of blocking under

all 4 corners of the deck (Fig. 5-14). This will set the
cutting height at 3 ¼ " (8.26). NOTE: Back of deck

When blocking up the rear discharge decks make
certain the blocks are not in the discharge opening.

4. Set cutting height at 3 ¼" (8.26 CM) in the height

indicator by placing the height adjusting stop in the 3"
(7.62 CM) hole, and turning the height stop so that the
flat side is against the stop handle. Fig. 5-15
NOTE: Refer to Deck Cutting Height Adjustment
section on how to set the cutting height.

5. Clamp the height adjusting stop against the stop handle

(5-15). This will assure that the height will not move
during the setting process. Otherwise, spring pressure
from the deck lift springs will tend to pull the stop
away from the handle.

6. Loosen all nuts on the deck lift threaded rods, and the
hardware on the adjuster (on the right front), until all

the deck lift chains are loose, and the deck is sitting
tightly on all four blocks. Fig. 5-16, 5-17, 5-18

7. Loosen the two nuts on the front of height indicator so

that the foot pedal is free. Fig. 5-19

8. Start the leveling process on the left front of the

tractor.

9. Set the amount of threads protruding on the deck lift

rod from the lift block at approximately 1" (2.54

CM).

Fig. 5-20

10. Jam both nuts against the block.

11. Push or pull on the deck lift foot pedal until the chain

on the left front just becomes tight, making sure that
the deck stays tight against the 3" (7.62 CM) block.

12. While keeping the chain tight, tighten the nuts against

the deck lift block on the height indicator rod. Fig. 5­19

13. Go to the right front of the tractor.

14. Loosen the 5/16" jam nut on the adjuster lift chain (5-

18), and back the adjuster bolt out to allow the adjuster
to move up and down freely.

15. Be sure that adjuster is free to move up and down.

16. Tighten the adjuster bolt until the chain just becomes

tight, making sure that the deck stays tight against the
3" (7.62

CM) block.

17. Tighten the adjuster bolt jam nut to prevent the

adjuster bolt from moving. Fig. 5-18

The notch located at the rear of the height adjusting bar

is to be used when the deck is placed in the transport mode.

Anti-scalp wheels

Anti-scalp wheel kits are standard on the Super Z Diesel.
These anti-scalp wheels are designed to minimize scalping
when mowing on rough uneven terrain.

After setting the cutting height, adjust the anti-scalp
wheels so they extend below the deck but do not contact
the ground. They should always be at least 1/4” to 3/4” (.6
cm to 1.9 cm) below the deck. With the unit sitting on a flat
level surface, the wheel position can be adjusted up or down
as needed from 3/4” to 1-3/4” (1.9 cm to 9.5 cm) below the
blade surface. Move the front wheels up or down, in 1/2”
(1.3 cm) increments, using the different axle mount holes in
the wheel mount bracket. Fig. 5-23

NOTE: When the anti-scalp wheels are installed, the
minimum cutting height is 1” (2.5 cm) with the anti-scalp
