To the new owner

The purpose of this manual is to assist owners and
operators in maintaining and operating the Hustler TrimStar
Hydro. 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 on the unit 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 remove 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.

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 facing forward while
operating the unit, 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 unit 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

Unit model and serial numbers are found on the serial
identification plate, located on the left side of the frame next
to the left drive wheel.

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

Parts and service

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

1. Correct part description and number, as given in the

parts manual supplied with your owner’s packet.

2. Correct model number.

3. Correct serial number.

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

PERSONAL SAFETY for operators and other persons
during the normal operation and servicing of this equipment.

DANGER – denotes immediate hazards which WILL
result in severe personal injury or death.

WARNING - denotes a hazard or unsafe practice which
COULD result in severe personal injury or death.

This manual uses two other words to highlight

information. IMPORTANT calls attention to special
mechanical information and NOTE: emphasizes general
information worthy of special attention.

All operators should read this manual, or be instructed
about safe operating and maintenance procedures. This is
the owner’s responsibility.

Improper use or maintenance by the operator or
owner can result in injury. To reduce the potential for
injury, comply with these safety instructions and always
pay attention to the safety alert ▲ symbol, which means
DANGER or WARNING - “personal safety
instructions.” Failure to comply with the instructions
may result in personal injury or death.

Incorrect usage of this machine may result in severe
injury. Personnel operating and maintain- ing it should
be trained in the proper use and should read the
manuals completely and thoroughly before attempting to
set-up, operate, adjust, or service this machine.

The Quick Reference Decals located on the unit 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 remove 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 Decal 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.

The owner should also ensure that the operator/mechanic
know that they are responsible for their own safety as well
as the safety of other persons within the vicinity.
Remember, the operator is responsible for accidents or
hazards occuring to other people or their property.

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, engage park brake, place H-bar
steering in neutral, place cruise control lever in neutral
position, stop engine, and remove ignition key when
leaving the unit.

▲

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

▲

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 keep engine and machine clean, removing
accumulated dirt, trash and other material from
machine. Clean up oil or fuel spillage. Allow
machine to cool before storing.

▲

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 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.

▲ 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.

▲

Always inspect machine for damage after striking a
foreign object. If damage is found, repair machine
immediately. Be sure to disengage deck clutch, place
park brake lever in park brake position, stop tractor
engine, and remove ignition key when leaving
operator’s seat to inspect damage.

▲

Always be aware of what is behind the machine before
backing up.

▲

Never rotate forward suddenly on H-bar handle while
the machine is in rearward motion.

▲

When traveling in reverse, rotate handle forward
gently and avoid sudden movement. Rapid movement

SAFETY PRECAUTIONS

104893 10/05

2-2

of the handle 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.

▲

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

▲

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

▲

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

▲

Turn off blades when not mowing.

▲

Slow down before turning.

▲

Stop the engine before removing the grass catcher or
unclogging the discharge chute. Never clear the
discharge chute with the engine running. Turn off the
engine and be sure the blades have stopped before
cleaning. Use a stick to clear a plugged discharge area.

Never use your hand!

▲

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

▲

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

▲

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

▲

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

▲

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 H-bar handle in either direction could
result in a reaction of the unit that can cause serious
injury.

▲

If any attachment or additional weight is mounted on
the rear of the unit, any sudden movement of the H-bar
handle could cause the front of mower to come off of
the ground resulting in possible loss of control and
serious injury.

▲

The use of any other manufacturer’s attachments,
including stand-up sulkies, increases the risk of
operator injury, therefore, extreme caution must be
exercised when using these devises.

▲▲

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.

Slope Operation

Slopes are a major factor in loss-of-control and tip-over
accidents, which can result in sever 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.

• To check a slope, attempt to back up it. If the unit
can back up the slope without the operator and drive
wheels slipping, reduce ground speed and proceed
with caution.

• Do not operate the TrimStar Hydro on slopes when
using a stand-up sulky.

▲

Always be sure of your footing. Keep a firm hold on
the H-Bar handle and walk - never run.

▲

Block or chock the machine when parked on a slope or
when trailering.

▲

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 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.

▲

The Hustler mower is capable of operating
horizontally (traverse) on moderately steep slopes.
When operating on slopes of 15 degrees or more, be
aware of any conditions that may cause the 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.

Refer to Figure 2-1, page 2-5, 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

104893 10/05

2-3

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.

▲

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.

Service

▲

Always keep engine and machine clean, removing
accumulated dirt, trash and other material from
machine. Clean up oil or fuel spillage. Allow machine
to cool before storing.

▲

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

▲

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

▲

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

▲

Never attempt to make any adjustments or repairs to
the drive system or mower deck while the engine is
running or deck clutch is engaged. Mower blades
cannot be seen and are located very close to the deck
housing. Fingers and toes can be cut off instantly.
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.

▲

Keep nuts and bolts tight, especially the blade
attachment bolts. Keep equipment in good condition.

▲

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

▲

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

▲

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

Engine starting

The TrimStar Hydro safety interlock system is also
designed to protect the operator and others from accidental
injury due to unintentional engine starting. The engine will
not start until:

A. Cruise control is in the neutral (down) position.

Fig. 3-5

B. Deck clutch switch is in the disengaged (down)

position.

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

NOTE: The machine is equipped with operator presence
control switches. If for any reason the operator should
release both of the operator presence control levers when the
cruise control is not in neutral (up) or the deck clutch switch
is engaged (up position), the engine will stop.

DANGER: The operator presence switches
should never be engaged when starting the unit.
When the operator presence switches are
engaged, they override the cruise control’s
neutral switch and the deck clutch interlock
system. Severe personal injury could result
when starting the unit if the operator presence
switches are engaged.

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

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

operation checking.

2. Make sure the cruise control is in the neutral (down)

position and deck clutch switch is disengaged (down
position).

3. When the engine is cold place the choke lever in the

choke (up) position. Avoid flooding and operate
engine without choking as soon as possible.
When the engine is already warmed up set throttle to
approximately 1/2 throttle position.
NOTE: If the ambient temperature is below 50
degrees disengage the cold weather pump clutch
before attempting to start the engine. Refer to the Cold
Weather Pump Clutch section for more information.

4. Insert key in ignition switch and rotate full clockwise.

Pull engine recoil start rope.

5. Perform test to make sure safety interlock system is

operating properly. Refer to Safety interlock system
section.

6. Allow the engine to idle a few minutes before

advancing the throttle and engaging the clutch. Press
operator’s presence control levers, the cruise control is
not in neutral (Fig. 3-6) and rotate the H-bar slowly
forward.

7. Before stopping the engine, place the H-bar handle in

the neutral position, set cruise control in the neutral
(down) position, disengage the deck clutch, and

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

Cold weather pump clutch

The TrimStar Hydro is equipped with a pump clutch that
disengages the pump clutch belt. When the belt is
disengaged, the engine will start easier in colder temp­eratures.

To disengage the pump clutch, pull the chain until the
tension is released from the pump drive belt and latch in the
slot. Fig. 3-7

To engage the pump clutch, with H-bar locked in
neutral, release the chain from the latching slot.

Never operate the unit with the pump clutch partially
engaged. Make sure the clutch is completely released and

the chain has slack.

Safety interlock system

The unit is equipped with a safety interlock system
consisting of the cruise control neutral switch, operator
presence control levers (Fig. 3-4), and deck clutch switch.

Check the safety interlock system daily, prior to
operation. This system is an important safety feature. It
should be repaired immediately if it malfunctions. The
machine incorporates two operator presence control
switches which will stop the tractor engine when the
operator releases both of the operator presence control levers
for any reason while the tractor is operating. However, if
only one operator presence control lever is released, the unit
will continue to operate. This is a safety feature designed to
prevent runaway or accidental entanglement. To inspect the
system:

1. Place the H-bar lever in the neutral position, move

cruise control to the neutral (down position), and move
deck clutch switch to the disengaged (down) position.

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

temperature.

3. With the cruise control out of neutral (up) position

and/or the deck clutch switch engaged (up position),

slowly release both operator presence control levers.

The engine should stop within a few seconds.

4. Place the cruise control to the neutral (down) position

and the deck clutch switch disengaged (down)
position. The engine should continue to run without

the operator presence control switches engaged.

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

is engaged or the cruise control is not in the neutral
position and both operator presence control levers are
released, check the function of the operator presence
control switches. If these switches are not operating
properly (not opening or closing) contact your
Authorized 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 operator presence control
switches.

Moving unit with stalled engine

If it becomes necessary to move the tractor when the
engine is inoperative, the integrated pump/motor units are
equipped with bypass valves. Before moving the unit, shift
the park brake lever to the bypass valve position. (Fig. 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 unit must be
tied down to the transporting vehicle.

IMPORTANT: Always make certain the park brake
lever is returned to the drive position before running the unit
following repairs.

Steering the unit

DANGER: Never make sudden stops or reverse

direction, especially when operating on a slope.
The steering is designed for sensitive response.
Rapid rotation of the H-bar handle in either
direction could result in a reaction of the tractor
that can cause serious injury.

After starting engine, steer as follows:
To go forward, move park brake lever to drive position,

and move the cruise control out of neutral (up posiiton) and
rotate H-bar handle forward (Fig. 3-9).

To go in reverse, rotate the H-bar handle to the neutral

position. After achieving neutral, rotate lever rearward.

To turn left, rotate the H-bar handle to the left and out of

the neutral position.

To turn right, rotate the H-bar handle to the right and out

of the neutral position.

To zero turn, rotate H-bar handle the direction desired

with the handle in the neutral position. This will allow the
drive wheels to counter-rotate.

To stop or decrease speed, move H-bar handle to neutral.

When going forward rotate handle rearward gently. When
going in reverse rotate handle forward.

DANGER: When traveling in reverse rotate
handle forward gently 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.

To increase speed, move the cruise control lever farther

forward. This allows the H-bar handle to rotate further from
neutral. The farther the H-bar handle is rotated forward from
neutral, the faster unit will travel forward. The farther the
H-bar handle is rotated rearward from neutral, the faster unit
will go in reverse.

Mower deck leveling

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

Deck level adjustments

Leveling the deck must be done in the following manner
and order:

1. Check tire pressures to make certain they are properly

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

Drive wheels tire pressure....................8 - 12 psi

Gauge wheels tire pressure.................12 - 16 psi

WARNING: Stop engine. Place the H-bar lever
in the neutral position, move cruise control to the
neutral (down position), place park brake lever in
the park brake position and move deck clutch
switch to the disengaged (down) position.

2. Park the unit on a flat surface.

3. Set the deck at a cutting height of 3” (4th hole from the

top of pin).

4. Loosen the rear deck pin lock nut hardware. Fig. 3-11

5. Measure from level surface to top of mower deck (as

indicated in Fig. 3-10). Note this dimension.

6. Add 1/8” to this measurement and adjust the rear deck

pins until this dimension is achieved. Measure near
the rear deck pins.

7. Tighten the rear deck pin lock nut.

Deck cutting height adjustment

Deck height is adjustable from 1.25” to 4.5” (3.18 cm -

11.43 cm) in 1/4” increments. The holes in the height

adjusting pins are spaced at 1/2” intervals. When the hair

pin is placed in the uppermost hole of the height adjusting

pin, with the two spacers under it, the cutting height is at

1-1/4”. (Fig. 3-11) NOTE: There should always be at

least one spacer under the hair pin.

If the hair pin is placed in one of these holes, with one
spacer between the hair pin and the deck carrier height
adjusting bracket, then the deck height will be set at one of
the following: 1-1/4”, 1-3/4”, 2-1/4”, 2-3/4”, 3-1/4”, 3-3/4”
or 4-1/4”.

If the two spacers are placed between the hair pin and the
deck carrier height adjusting bracket (Fig. 3-9), then the
deck height will be set at one of the following: 1-1/2”, 2”, 2­1/2”, 3”, 3-1/2”, 4” or 4-1/2”.

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 to slip, resulting in premature wear or possible damage.

Operating suggestions

DANGER: Prior to operating the unit the

operator should be thoroughly familiar with the
proper use and operation of the equipment,
should have 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 untrained and
inexperienced operator should not mow on
slopes or on uneven terrain.

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 and
safety shoes when operating this machine.

WARNING: The unit’s H-bar handle is very
responsive: Easy does it! For smooth operation,
rotate handle slowly, avoid sudden movement.
Skill and ease of operation come with practice
and experience.

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 lose control
of the equipment. If the depression or obstacle
can not be avoided, 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.

The following list is not all inclusive.

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.

Unit 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 cruise control and the H-bar
handle to control ground speed rather than engine rpm. Set
the cruise control to a comfortable walking speed.

The safety interlock system is designed to shut the engine
off if the operator releases the operator presence control
levers when the cruise control is engaged or the deck clutch
lever is engaged the engine will stop.

When operating the TrimStar Hydro on slopes, the
operator should mow traversing the slope. The operator
should stay more on the uphill side of the unit when
mowing.

104893 10/05

Spacers

Height

adjusting

pin

WARNING: To check a slope, attempt to back

up it. If the unit can back up the slope without
the operator and drive wheels slipping, reduce
ground speed and proceed with caution.

For additional safety issues regarding slope mowing refer

to the Safety section of this manual.

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 TrimStar Hydro 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 (Fig. 3-12) 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.

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.

Avoid sudden turns on wet turf. This can damage turf

unnecessarily.

Always check area to be mown for rocks and other debris

before mowing.

Stand-up sulkies

Hustler Turf Equipment does not warrant or accept

liability for the use of any attachments not manufactured
by Hustler Turf Equipment, including the use of stand­up sulkies.

All manufacturer’s safety instructions issued with any

attachments including stand-up sulkies must be followed.

WARNING: Never operate the Hydro Walk­Behind on slopes when using a stand-up sulky.

WARNING:The use of any other manufact­urer’s attachments, including stand-up sulkies,
increases the risk of operator injury, therefore,
extreme caution must be exercised when using
these devises.

Introduction

WARNING: Unless specifically required, DO

NOT have engine running when servicing or
making adjustments to tractor. Always
disengage deck clutch, place H-bar steering in
neutral, place cruise control lever in neutral
position, stop engine, and remove ignition 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.

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.

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.

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.

Description of deck operation

The blades are indirectly driven by the engine through a
V-belt drive system. The V-belt drives a pulley located on
top of spindle housing assemblies. The pulleys drive 1”
spindle shafts which in turn drive the blades. A blade is
affixed to each spindle shaft by a 5/8” bolt.

WARNING: Particular attention must be given

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

Torque values given below:

Ft-lbs. Nm

Wheel (lug) nuts..................65-75..................88 -102

Blade spindle bolts (top).....65-75..................88 -102

Blade spindle bolt (bottom)....118...................160.01

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...............................................8-12 psi

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

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

The mower blade spindle assemblies require lubrication
after every 500 hours of use or annually, whichever occurs
first. Each spindle shaft is equipped with a grease zerk

located on under the deck. Use no more than one or two
ounces of SAE multi-purpose 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.

Hydraulic system

The TrimStar Hydro is equipped with two Hydro-Gear

C-IZT integrated pump/motor transmissions.

These units have a replaceable filter which will require
replacement every 200 hours or 2 years whichever comes
first. The required service involves draining the oil and
installing a new filter kit (Hustler p/n 789511). Fill with
new 20W50 engine oil.

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.

To replace the filter use the following procedure:

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

off the floor. Place the jack stands under the izt guard
to support the machine.

WARNING: Make sure the transmissions are
cool before performing service procedures.

2. Remove the drain plug and filter from the integrated

pump/motor transmission and drain the oil into a
drain pan. Dispose of the oil in a proper manner.
This oil will not be re-used. Fig. 4-3

3. Install a new filter kit into the transmission.

4. Remove the lower side plug and install the magnetic

plug included with the kit. Fig. 4-3

5. Repeat steps 2 through 4 for the other side.

6. Lower the tractor. NOTE: The unit must be level

when filling and checking the oil.

7. Remove the fill plug from the transmission and fill

with new, clean 20W50 engine oil. It will require
approximately 2 - 2.46 quarts of oil to fill the
transmission. Re-install the fill plug. Fig. 4-4

WARNING: Do not overfill. If you overfill the
unit while it is “cold”, it may overflow as it
reaches normal operating temperatures. The oil
level should be to the bottom of the fill plug.
Fig. 4-4

8. Start the unit and drive it forward and rearward 5

times approximately 10 - 20 feet each time.
If it feels smooth then the unit is ready to operate.
If either side moves slower than the other or sluggish
then the system will need to be purged. Follow steps
9 through 12 until the air is purged from the system.

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

off the floor.

10. With the park brake lever in the bypass valve position

and the engine running at 1/2 throttle, rotate the H-bar
slowly forward and rearward 5 to 6 times to allow air
to be purged from the system. As this occurs, the oil
level will drop.

11. With the park brake lever in the drive position and the

engine running, rotate the H-bar slowly forward and
rearward 5 - 6 times. Stop engine and place H-bar in
the neutral position. Lower the tractor and check the
oil level. Add oil as required.

12. Start the unit and drive it forward and rearward 5

times approximately 10 - 20 feet each time.
If it feels smooth then the unit is ready to operate.
If either side moves slower than the other or sluggish
then the system will need to be purged again. Follow
steps 9 through 12

NOTE: The C-IZT integrated pump/motor transmissions
are equipped with bypass valves. For more information
refer to Operation section, Moving tractor with stalled
engine.

WARNING: When washing the mower, direct
spray away (especially if using a power washer)
from the Hydro-Gear C-IZT transmission’s seals
to prevent water intrusion and to ensure
component performance.

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.

The 5.0 U.S. gallon (18.9 liter) fuel tank is located

behind the engine. Fig. 4-5

Use regular unleaded gasoline with an octane rating of 87

or higher.

The fuel filter is installed in the fuel line between fuel
tank and engine fuel pump. Replace filter annually or after
every 500 hours of operation, whichever occurs first. Fig. 4­6

When replacing the fuel filter, check the fuel line hoses
and fuel shut-off valve grommet for any cracks or leaks.
Replace as needed.

A fuel shut-off valve is located on the underneath side of

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 may occur when operating on a slope.

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, engage parking brake and neutral lock
levers 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 rock, branch or other
foreign object during mowing!

Mower blade removal

Use a 15/16" wrench to remove the 5/8" cap screw
holding blade to spindle shaft from underneath.

Sharpen the blades on a grinder following pattern as
shown (Fig. 4-11). 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 5/8" 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. 4-12 and 4-13). Replace any distorted blade.

Do not re-use spindle bolts which have stripped, worn or
undercut threads. Torque bolts to 118 foot-pounds (160.01
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.

Deck height adjusting shaft
and bushing

The deck height adjusting pin and bushing can be replaced
if they become worn. Refer to the Parts Manual for the
proper replacement parts. Fig. 4-14 and 4-15

neutral must be adjusted per the following instructions. To
adjust:

1. Place the H-bar in the neutral position.

2. Raise and block the tractor so that the drive wheels are

not making contact with the floor. Approximately 2” ­3” off of ground.

3. Start the engine. Leave the H-bar in the neutral

position.

4. If rear wheels rotate forward or rearward, loosen the

locking hardware on the turnbuckle assembly. Fig. 5­2

5. Tighten or loosen the turnbuckle until rear wheel

comes to a stop. Retighten locking hardware.

6. Neutral should now be set.

7. With engine running, move cruise control lever out of

the neutral position to allow wheels to rotate forward.

ADJUSTMENTS

Introduction

WARNING: Unless specifically required, DO

NOT have engine running when servicing or
making adjustments to the unit. Place H-bar
handle in the neutral position, engage neutral
lock lever, 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 Hustler TrimStar Hydro was adjusted before it left
the factory and was checked during predelivery setup.
However, after start-up and continued use, a certain amount
of break-in wear will cause some adjustments to change.

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

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, engine oil and engine
combustion air; minute dust particle are abrasive to close­tolerance engine and hydraulic assemblies.

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

Torque values

WARNING: Particular attention must be given

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

Torque values given below:

Ft-lbs. Nm

Wheel (lug) nuts..................65-75..................88 -102

Blade spindle bolts (top).....65-75..................88 -102

Blade spindle bolt (bottom)....118...................160.01

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.

4. Remove the deck cover.

5. Remove the brake spring. Fig. 5-4

6. Loosen the locking nut and the outside adjusting nut.

Measure from the end of the threaded linkage rod to

the inside adjusting nut. This dimension should be 1-

1/4” - 1-1/2””. If it is not adjust the inside adjusting

nut until the dimension is attained. Fig. 5-5 & 5-6

7. Tighten the outside adjusting nut until there is a 1/16”

gap between it and the brake linkage adjusting plate.

Fig. 5-6

8. Tighten the locking nut against the outside adjusting

nut. Fig. 5-6

9. Re-attach the brake spring.

10. To test the brake adjustment, slide the park brake lever

from the drive position into the park brake position
(Fig. 5-7). The brakes should be engaged. If they are
not, it will be necessary to adjust the two adjusting
nuts a little one way or the other until the brakes are
fully engaged.

Pump drive belt adjustment

The pump drive belt tension remains constant by means of
a tension idler and spring (Fig. 5-8). The spring tension
should be such that the belt does not slip under normal
operating load conditions, assuming the belt is not
excessively worn or damaged. As belt stretches and wears
in, adjustment may become necessary. To increase belt
tension, move the spring chain one (or more) link(s) at the
anchor bracket. Installed spring length should be 5.0" ± .5"
(12.7 cm ± 1.27 cm) originally with adjustments of .60"
(15.2mm) per chain link. Fig. 5-9

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

Deck drive belt adjustment

The deck drive belt tension remains constant by means of
a tension idler and spring (Fig. 5-8). The spring tension
should be such that the belt does not slip under normal
operating load conditions, assuming the belt is not

excessively worn or damaged. As belt stretches and wears
in, adjustment may become necessary. To increase belt
tension, move the spring chain one (or more) link(s) at the
anchor bracket. Installed spring length should be 5.50" ± .5"
(12.7 cm ± 1.27 cm) originally with adjustments of .60"
(15.2mm) per chain link. Fig. 5-10

IMPORTANT: Do not over tension the spring to

compensate for a badly worn belt or pulley.

Deck spindle belt adjustment

The spindle belt tension remains constant by means of a
tension idler and spring (Fig. 5-8). The spring tension
should be such that the belt does not slip under normal
operating load conditions, assuming the belt is not

Engine RPM setting

The TrimStar Hydro is designed so that the engine will
run at 3600 rpm static pump load only. At this speed the
hydraulic pumps are running at their maximum rated speed.

Cruise control spring adjustment

The cruise control tension can be adjusted. The more
tension that is placed on the spring results in the cruise
control engaging quicker. Less spring tension results in the
operator having more control over the cruise control.

Adjust the cruise control tension by moving the spring
chain at the anchor bracket. Fig. 5-12

Anti-scalp wheels

Anti-scalp wheel kits are standard on the TrimStar Hydro.
(Fig. 5-13) This anti-scalp kit is recommended 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 wheels up or down, in 1/2” (1.3
cm) increments, using the different axle mount holes in the
wheel mount bracket. Fig. 5-13

NOTE: When the anti-scalp wheels are installed the
minimum cutting height is 1” (2.5 cm) with the anti-scalp
wheels set at 3/4”.

When storing the unit at the the end of the mowing
season, the following steps should be taken to ensure
readiness for the next mowing season.

1. Remove all grass, dirt, and trash from tractor and

mower. Clean tractor and mower and touch up all
scrapes with Hustler spray paint.

2. Clean paper air filter. Replace if necessary. Wash and

re-oil foam precleaner.

3. Check thoroughly for any worn or damaged parts that

need replacing and order them from your dealer.

4. Thoroughly lubricate machine, according to

lubrication instructions.

5. Block unit up so weight is off tires.

NOTE: Do not deflate tires.

6. Perform separate engine preparation as listed below.

7. Store tractor in a clean, dry place.

Preparation of engine for storage

When engine is to be unused for long periods, proceed as
follows:

1. Run engine for a minimum of 15 minutes.

2. Drain oil from crankcase while engine is still warm.

3. Refill with fresh oil of proper viscosity.

4. Drain fuel tank and run the engine until it stops from

lack of fuel. Gasoline evaporates if left in carburetor
for long periods, forming gum and varnish deposits in
carburetor. These deposits will cause engine flooding
and loss of power.

5. Remove and replace fuel filter if not done in previous

100 hours.

6. Clean exterior surface of engine. Spread a light film

of oil over any exposed metal surfaces of engine that
are subject to corrosion.

7. Clean dirt and chaff from cylinders and fins, blower

housing and muffler.

8. Check oil filler cap and fuel tank cap to make certain

they are securely in place.

New season preparation

Before starting the tractor following post season storage,

the following servicing is required:

1. Clean tractor, removing trash and dirt accumulation.

2. Check engine oil oil levels.

3. Fill fuel tank with fresh gasoline. Run machine at half

speed for 5 minutes, checking operation of steering
control lever. Stop engine and check for oil leaks,
loose fittings and so forth.

4. Tighten any bolts that have loosened and make sure all

hair pins, cotter pins and clevis pins are in place.

5. Install all safety shields and review safety precautions

listed in this manual.

6. Check and inflate drive tires to 8-12 psi.
