Operation  
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!  
Evaluate the terrain to determine what accessories and attachments  
are needed to properly and safely perform the job. Only use  
accessories and attachments approved by the manufacturer.  
Never leave a running machine unattended. Always stop on level  
ground, disengage deck clutch, place steering control levers in park  
brake position, stop tractor engine, and remove ignition key before  
leaving operator’s seat for any reason including emptying the catcher  
or unclogging the chute.  
▲
▲
Always keep clear of the mower blades and attachments during  
operation.  
Do not operate the machine while under the influence of alcohol or  
drugs.  
Exercise caution when loading or unloading the machine onto a  
trailer or truck.  
Always wear safety goggles or safety glasses with side shields when  
operating the mower.  
Data indicates that operators, age 60 years and above, are involved  
in a large percentage of riding mower-related injuries. These  
operators should evaluate their ability to operate the mower safely  
enough to protect themselves and others from serious injury.  
Follow the manufacturer’s recommendation for wheel weights or  
counterweights.  
If any attachment or additional weight is mounted on the rear of the  
unit, any rapid movement of the control levers in either direction  
could result in a reaction of the tractor that can cause serious injury.  
Clean flammable material from machine. Prevent fires by  
keeping engine compartment, exhaust area, battery, fuel line,  
fuel tank and operator’s station clean of accumulated trash,  
grass clippings, and other debris. Always clean up spilled fuel  
and oil.  
▲
▲
▲
▲
▲
Do not change the engine governor setting or overspeed the engine.  
Always remain seated while operating machine.  
▲
▲
▲
▲
Always keep safety shields and covers in place, except for servicing.  
Always maintain a safe distance from people and pets when  
mowing. Always stop machine if someone enters the area.  
Always operate machine in daylight or with adequate working lights.  
Follow daily and weekly checklists, making sure hoses are tightly  
secured and bolts are tightened.  
Always observe traffic laws while driving machine from one  
location to another. Watch for traffic when operating near or  
crossing roadways.  
Always be alert for hazards such as rocks, metal objects and other  
debris which may be thrown or entangled by mower blades. Watch  
out for holes or deep depressions.  
Inspect area to be mowed for hazards such as rocks, metal objects  
and other debris which may be thrown or entangled by mower  
blades. Remove these objects before mowing.

Always inspect machine for damage after striking a foreign object. If  
damage is found, repair machine immediately. Be sure to stop on  
level ground, disengage deck clutch, place steering control levers in  
park brake position, stop tractor engine, and remove ignition key  
when leaving operator’s seat to inspect damage.  
Always buckle seat belt, if provided with one, and only if a ROPS is  
installed properly, before starting tractor.  
▲
▲
▲
▲
Always wear adequate ear protection, such as earplugs, when  
operating this equipment as prolonged exposure to uncomfortable or  
loud noises can cause impairment or loss of hearing. Do not wear  
radios or music headphones while operating the machinery. Safe  
operation requires your full attention.  
Do not operate the equipment while wearing sandals, tennis shoes,  
sneakers, shorts or any type of loose fitting clothing. Long hair,  
loose clothing or jewelry may get tangled in moving parts. Always  
wear long pants, safety glasses, ear protection and safety shoes when  
operating this machine.  
Always be aware of what is behind the machine before backing up.  
Do not mow in reverse unless absolutely necessary. Always look  
down and behind before and while backing up.  
Never push forward suddenly on your control levers while the  
machine is in rearward motion because machine may tip backwards.  
Never pull back suddenly on your control levers while the machine  
is in forward motion.  
When moving in reverse, push forward slowly on control levers and  
avoid sudden movement. Rapid movement of the control levers in  
either direction could result in a reaction of the tractor that can cause  
serious injury.  
Never operate a poorly maintained machine.  
Never attempt high speed maneuvering, especially in crowded or  
congested areas.  
Using a ramp  
Use extreme caution when loading and unloading a unit onto a truck  
▲
or trailer with a ramp.  
Use only a single, full width ramp; do not use individual ramps for  
each side of the unit. Having a full width ramp provides a surface  
for the tractor frame to contact if the unit starts to tip backwards. It  
also reduces the risk of a wheel going off and the machine tipping  
over.  
▲
Do not exceed a 15 degree angle between the ramp and the ground  
or between the ramp and the trailer or truck.  
When on a ramp avoid sudden acceleration  
▲
▲
Slope Operation  
▲
▲
▲
Slopes are a major factor in loss-of-control and tip-over accidents,  
which can result in severe injury or death. All slopes require extra  
caution. If you cannot back up the slope or if you feel uneasy on it; do  
not mow it. REMINDER: Only operate on slopes of 15 degrees or less.  
Use extreme caution when operating on slopes.  
▲
•
•
•
•
•
Be extremely careful changing directions on a slope. Slow down.  
Do not operate where the machine could slip or tip.  
Turn slowly  
▲
▲
Turn on the most level part of the slope  
To maximize traction, it is better to turn the front of the machine  
uphill, rather than downhill. If drive tires lose traction, steering  
control is lost which could cause serious injury or death.  
If it becomes necessary to turn downhill, turn slowly and  
gradually, if possible.  
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.  
▲
•
Do not remove or modify the stabilizer wheels.  
▲
▲
▲
▲
Watch for holes, ruts, bumps, rocks or other hidden objects. Uneven  
terrain could overturn the machine. Tall grass can hide obstacles.  
Remove obstacles such as rocks, tree limbs, etc.  
Never carry passengers.

Keep all movement on slopes slow and gradual. Do not make  
sudden changes in speed or direction.  
The attachments mounted to the tractor will also affect the way it  
handles on a slope. Be aware that each attachment’s characteristics  
vary.  
Do not tow on slopes. The weight of the towed equipment may  
cause loss of traction and loss of steering control.  
Another consideration to safe mowing on slopes is to be aware of  
what is located at the bottom of the slope. Extreme caution should  
be used when there is a hazard located at the bottom of the slope.  
Some examples are:  
▲
▲
▲
Avoid starting and stopping on a slope. If tires lose traction,  
disengage the blades and proceed slowly straight down the slope.  
Mow a safe distance (minimum of 10 feet) away from drop-offs,  
retaining walls, drainage ditches, embankments, water, and other  
types of hazards to avoid a wheel dropping over the edge or to avoid  
the ground from breaking away. This will reduce the risk of the  
machine suddenly rolling over causing serious injury or death.  
Use a walk behind, push mower or hand-held trimmer on slopes and  
near drop-offs, retaining walls, drainage ditches, embankments and  
water to avoid machine rollover and serious injury or death.  
Do not mow on wet grass. Slippery conditions reduce traction  
which could cause sliding and loss of control.  
Do not tow on slopes. The weight of the towed equipment may  
cause loss of traction and loss of control.  
Do not try to stabilize the machine by putting your foot on the  
ground.  
If the mower’s tires lose traction when operating on slopes,  
disengage the blades, place the control levers in the park brake  
position, turn the engine off and get help.  
Never make sudden starts, stops, turns, or reverse direction,  
especially when maneuvering on slopes. The steering is designed  
for sensitive response. Rapid movement of the control levers in  
either direction could result in a reaction of the tractor that can cause  
serious injury.  
1. Water; i.e. lake, river  
2. Cliffs, retaining walls  
3. Roads, highways  
4. Buildings  
▲
▲
▲
▲
▲
5. Rocks  
These are just a few examples of situations when caution must be  
used when operating on a slope. There are many other possibilities  
too numerous to mention. Just remember to always exercise extreme  
caution when operating on any slope.  
When operating on terrain where there is a potential for a roll  
over, it is important that a ROPS be installed on the equipment.  
The ROPS will minimize chance of injury or death from rollover.  
Seat belt must be fastened while operating a machine equipped  
with ROPS. Failure to use seat belt will result in serious injury in  
the event of a roll over.  
▲
▲
Children  
Never stop suddenly while backing down slopes. This action may  
result in a reaction of the tractor that can cause serious physical  
injury.  
The Hustler mower is capable of operating horizontally (traverse) on  
moderately steep slopes. When operating on slopes up to 15  
degrees, be aware of any conditions that may cause the tractor drive  
tires to lose traction resulting in a possible loss of control of the  
machine. An operator should not operate on a slope until he is  
thoroughly familiar with the equipment.  
▲
▲
Tragic accidents can occur if the operator is not alert to the presence of  
children. Children are often attracted to the machine and the mowing  
activity. Never assume that children will remain where you last saw  
them.  
Never leave machine unattended with ignition key in switch,  
especially with children present.  
▲
Children or bystanders may be injured if they move or attempt to  
operate the tractor while it is unattended. Always disengage deck  
clutch, place control levers in park brake position, stop tractor  
engine, and remove ignition key when leaving operator’s seat.  
Keep children out of the mowing area and under the watchful care of  
a responsible adult other than the operator.  
Be alert and turn the machine off if children enter the area.  
Before and while backing, look behind and down for small children.  
Never carry children, even with the blades off. They may fall off  
and be seriously injured or interfere with safe machine operation.  
Children who have been given rides in the past may suddenly appear  
in the mowing area for another ride and be run over or backed over  
by the machine.  
▲
Do not operate on slopes greater than 15 degrees.  
Refer to Figure 2-1, page 7, when determining the degree of slope to  
be mowed.  
▲
▲
▲
▲
IMPORTANT: The Hustler ATZ only, is capable of operating on  
slopes of 15 degrees or more (maximum 25 degrees). Do not  
operate the Hustler ATZ on slopes greater than 25 degrees.  
Refer to Figure 2-1, page 7 when determining the degree of slope to  
be mowed.  
Never allow children to operate the machine.  
▲
▲
▲
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  
Never allow children or others in or on towed equipment.  
Use care when approaching blind corners, shrubs, trees, the end of a  
fence or other objects that may obscure vision.  
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

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 near the  
top and are identified as a hex stud. The valve is located per Figure 3-7, 3-8  
& 3-9.  
The two-post ROPS can be pivoted down by removing the right and left  
retaining rings and pulling out on the pins 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. Use the ROPS in the

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  
Driving the tractor  
DANGER: Prior to operating the tractor the operator should  
be thoroughly familiar with the proper use and operation of  
the equipment, should read the manual completely and  
thoroughly, and should have attempted slow moving  
maneuvers to become familiar with the operation of the  
equipment before attempting normal speed operation. An  
inexperienced operator should not mow on slopes or on  
uneven terrain.  
DANGER: Never make sudden stops or reverse direction,  
especially when maneuvering on a slope. The steering is  
designed for sensitive response. Rapid movement of the  
control levers in either direction could result in a reaction of  
the tractor that can cause serious injury.  
After starting engine, engage the control levers and steer as follows:  
To go forward, push control levers forward an equal distance (Fig. 3-  
14).  
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.  
To go in reverse, pull control levers rearward an equal distance (Fig. 3-  
14).  
To turn left, move the right control lever farther forward from neutral  
than the left control lever.(Fig. 3-14)  
To turn right, move the left control lever farther forward from neutral  
than the right control lever. (Fig. 3-14)  
WARNING: The unit’s steering control levers are very  
responsive: Easy does it! For smooth operation, move lever  
slowly, avoid sudden movement. Skill and ease of operation  
come with practice and experience. The machine can spin  
very rapidly. Use caution when making turns and slow down  
before making sharp turns.  
“0” degree turn, move one control lever forward and the other control  
lever back of neutral. This will allow the drive wheels to counter-rotate.  
(Fig. 3-14)  
To stop or decrease speed, move control levers to neutral. When going  
forward pull back gently on control levers. When going in reverse push  
forward gently on control levers.  
For emergency stop, when traveling forward or rearward, place the  
steering control levers in the park brake position immediately.  
Inexperienced operators may have a tendency to oversteer and lose  
control. Slow-moving practice maneuvers are recommended to become  
familiar with these characteristics before attempting normal speed  
operation.  
DANGER: When moving in the rearward direction push  
forward gently on steering control levers and avoid sudden  
movement. Any sudden movement could cause the front of  
the mower to come off of the ground resulting in possible  
loss of control, causing serious injury or death.  
WARNING: Sharp depressions or raised obstacles (such as  
gutters or curbs) should not be directly approached at high  
speed in an attempt to “jump” them as the operator could be  
thrown from the equipment. Approach at a slow speed and  
angle one drive wheel at the obstruction. Continue at an  
angle until the wheel clears and then pivot the opposite wheel  
around.  
To make a three point turn to the right, move the left control lever  
farther forward from neutral than the right control lever and start the turn.  
Next, pull back on the control levers until they are past neutral and the  
machine starts to go rearward. Pull right control lever farther rearward  
from neutral than the left control lever until the rear of the machine has  
pivoted around. Then, push the control levers forward until they are both  
past neutral and the machine starts to go forward. Push the left control  
lever farther forward from neutral than the right control lever and finish the  
turn. (Fig. 3-15)  
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.  
IMPORTANT: Rapid movement of control levers is not recommended

Step 1  
Figure 3-16  
Use the control levers to control ground speed rather than engine rpm.  
Keep blades sharp. Many professional mowing companies have  
additional sets of blades and change blades twice a day: once in the  
morning and again at noon. Many problems with incorrect cutting patterns  
are due to dull blades or blades which have been sharpened incorrectly.  
Information on sharpening blades is listed in this manual’s maintenance  
section. In addition, most communities have individuals or companies  
which specialize in sharpening mower blades. Blade sharpness should be  
checked daily.  
DANGER: Never work with blades while engine is running  
or deck clutch switch is engaged (on). Always place deck  
clutch switch in the disengaged position, place control levers  
in the park brake position and turn engine off and disconnect  
negative battery cable. Block up mower when you must  
work under it. Wear gloves when handling blades. Always  
check for blade damage if mower strikes rock, branch or  
other foreign object during mowing!  
Step 2  
Use high blade speed. Your mower is designed to operate at full  
throttle. The throttle setting directly controls blade speed. The highest  
blade speed generally gives best cut.  
Direct grass discharge to right, away from unmown area. Select a  
mowing pattern that directs grass discharge towards the outside, not  
towards center, of mowing area. Generally, this means using a pattern  
utilizing left turns because side discharge is to right. In any case, avoid  
throwing grass discharge onto unmowed area because grass is then mowed  
“twice”. Mowing twice puts an unnecessary load on the unit and reduces  
mowing efficiency.  
Step 3  
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.  
Neutral  
Right control lever  
Left control lever  
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.

hole, the cutting height is at 1-1/4” (3.18 CM).  
The notch located at the rear of the height adjusting bar is to be used  
when the deck is placed in the transport mode.  
Anti-scalp wheels  
Anti-scalp wheel kits are standard on Hustler Mid Mount Z units.  
These anti-scalp wheels are designed to minimize scalping when mowing  
on rough uneven terrain.  
After setting the cutting height, adjust the front anti-scalp wheels so they  
extend below the deck but do not contact the ground. They should always  
be at least 1/4” to 3/4” (6.35MM to 19.05MM) below the deck. With the unit  
sitting on a flat level surface, the front wheel position can be adjusted up or  
down as needed from 3/4” to 1-3/4” (19.05MM to 44.45MM) below the blade  
surface. Move the front wheels up or down, in 1/2” (12.70MM) increments,  
using the different axle mount holes in the wheel mount bracket. Fig. 3-18  
When adjusting the rear anti-scalp wheels, the wheel should be in the  
lower axle mount hole when the front anti-scalp wheels are in the lower or  
middle axle mount holes. When the front wheels are in the upper axle  
mount hole, the rear wheels should be in the upper axle mount hole as well.  
NOTE: When the anti-scalp wheels are installed, the minimum cutting  
height is 1” (2.5 CM) with the anti-scalp wheels set at 3/4” (1.91CM).  
Adjusting  
holes  
Figure 3-18  
If the machine’s forward motion must be stopped while mowing, a  
clump of grass clippings may drop onto your lawn. To avoid this, move  
onto a previously cut area with the blades engaged.  
WARNING: Never direct discharge of material from mower  
deck towards bystanders. Do not operate the mower without  
either the discharge chute or the entire grass collection system  
in place. Fig. 3-16  
BAC-VACTM Mounting  
If a BAC-VAC™ is to be mounted to an Hustler ATZ tractor it will be  
necessary to remove the following from the unit:  
1. Drive wheel weights  
Mower deck operation  
2. Frame weights located between the drive wheels  
3. The front and rear mount legs of the ROPS structure. The two post  
ROPS structure will remain. Fig. 3-19  
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.  
The weights included with the BAC-VAC™ will be used instead of the  
Hustler ATZ tractor weights.  
If a BAC-VAC™ is mounted to the Hustler ATZ it will be necessary to  
remove the BAC-VAC™ and front wheel weights from the tractor and it  
will be necessary to re-attach the drive wheel weights, frame weights and  
the front and rear mount legs to the tractor before operating the unit on a  
slope.  
With the engine running, engage the deck clutch switch (Fig. 3-1) and  
advance engine throttle to full rpm.  
NOTE: Engaging the deck clutch at high engine rpm or when under  
heavy load (in tall grass for example) can cause belts and/or electric clutch  
to slip, resulting in premature wear or possible damage.  
ATZ Tilt Seat  
ATZ units produced after 081100000 will have a tilt seat as standard  
equipment. When the switch, located on the right steering control lever is  
depressed, the seat will tilt up to 15 degrees, from center, both directions.  
Fig. 3-20  
Deck cutting height adjustment  
Deck height is adjustable from 1” to 5” (2.54 CM - 12.7 CM) in 1/4” (.64  
CM) increments. The holes in the height adjusting bar are spaced at 1/2”  
(1.27 CM) intervals. By turning the height adjusting stop around, 1/4” (.64  
CM) increments can be attained due to the 1/4” (.64 CM) plate that is part of  
the stop. Fig. 3-17  
EXAMPLE: When the height adjusting stop is placed in the 1” (2.54  
CM) hole, with the 1/4” (.64 CM) plate facing to the front of the unit, the  
cutting height is at 1”. When the height adjusting stop is placed in the 1”  
(2.54 CM) hole, with the 1/4” (.64 CM) plate on the operator’s side of the

running. Turn off the engine and be sure the blades have stopped  
before cleaning. Use a stick to clear a plugged discharge area.  
Never use your hand!  
Grass collection system components are subject to wear, damage and  
deterioration, which could expose moving parts or allow objects to  
be thrown. Frequently check components and replace with  
manufacturer’s recommended parts, when necessary.  
Exercise caution when working under the deck as the mower blades  
are extremely sharp. Wrap the blade(s) or wear gloves and use extra  
caution when servicing them.  
This product is capable of amputating hands and feet and throwing  
objects. Always follow all safety instructions to avoid serious injury or  
death.  
▲
Service  
Unless specifically required, DO NOT have engine running when  
servicing or making adjustments to tractor. Park the machine on  
level ground. Place steering control levers in the park brake  
position, disengage deck clutch, lower deck, remove ignition switch  
key and disconnect negative battery cable before doing any  
maintenance. Wait for all movement to stop before adjusting,  
cleaning or repairing. Repairs or maintenance requiring engine  
power should be performed by trained maintenance personnel only.  
To prevent carbon monoxide poisoning, be sure proper ventilation is  
available when engine must be operated in an enclosed area. Read  
and observe safety warnings in front of manual.

Use only genuine Hustler replacement parts to ensure that original  
standards are maintained  
Introduction  
Regular maintenance is the best prevention for costly downtime or  
expensive, premature repair. The following pages contain suggested  
maintenance information and schedules which the operator should follow  
on a routine basis. The following pages contain suggested maintenance  
information and schedules which the operator should follow on a routine  
basis. For more detailed information order the correct parts manual for  
your unit. Refer to the Product Literature section of this manual.  
Remain alert for unusual noises, they could be signaling a problem.  
Visually inspect the machine for any abnormal wear or damage. A good  
time to detect potential problems is while performing scheduled  
maintenance service. Correcting the problem as quickly as possible is the  
best insurance.  
Before working on or under the deck, make certain engine cannot be  
accidentally started. Shut engine off, remove ignition switch key  
adn disconnect negative battery cable for maximum safety. Repairs  
or maintenance requiring engine power should be performed by  
trained maintenance personnel only.  
▲
Except when changing or checking belt, always keep belt covers on  
mower deck for safety as well as cleanliness.  
Use a stick or similar instrument to clean under the mower making  
sure that no part of the body, especially arms and hands are under  
mower.  
▲
▲
Clear away heavy build-up of grease, oil and dirt, especially in the  
engine and under the seat platform areas; minute dust particle are abrasive  
to close-tolerance engine and hydraulic assemblies.  
Keep your machine clean and remove any deposits of trash and  
clippings, which can cause engine fires and hydraulic overheating as  
well as excessive belt wear. Clean up oil or fuel spillage. Allow  
machine to cool before storing.  
Clean flammable material from machine. Prevent fires by  
keeping engine compartment, top of deck, exhaust area, battery,  
hydraulic lines, fuel line, fuel tank and operator’s station clean  
of accumulated trash, grass clippings, and other debris. Always  
clean up spilled fuel and oil.  
▲
▲
Daily inspect mower for grass clippings and wire and string tangles.  
The underside of the mower deck will collect a build-up of grass clippings  
and dirt, especially when grass is wet or has high moisture content. This  
build-up will harden, restricting blade and air movement and will probably  
show a poorer quality of cutting. Therefore it should be removed routinely.  
To do this it will be necessary to raise and block the deck, using jack  
stands or blocks, in the full up position and scrape the build-up from  
underneath.  
Always wear adequate eye protection when servicing the hydraulic  
system and battery, or when grinding mower blades and removing  
accumulated debris.  
▲
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.  
Use extra caution when handling gasoline and other fuels. They are  
flammable and vapors are explosive.  
Never attempt to start engine when there is a strong odor of gasoline  
fumes present. Locate and correct cause.  
Never remove the fuel cap or refuel tractor while engine is running;  
never refuel near an open flame or near devices which can create a  
spark. Refuel outdoors. Never refuel or drain the fuel from the  
machine indoors.

correctly torque these items may result in the loss of a wheel  
or blade, which can cause serious damage or personal injury.  
Never run the engine in an enclosed area unless exhaust is vented to  
the outside. Exhaust gases contain carbon monoxide which is  
odorless and deadly poison.  
Never attempt to make any adjustments or repairs to the tractor drive  
system, mower deck or any attachment while the tractor engine is  
running or deck clutch is engaged. Repairs or maintenance requiring  
engine power should be performed by trained maintenance personnel  
only.  
Never work under the machine or attachment unless it is safely  
supported with jack stands. Make certain machine is secure when it  
is raised and placed on the jack stands. The jack stands should not  
allow the machine to move when the engine is running and the drive  
wheels are rotating. Use only certified jack stands. Use only  
appropriate jack stands, with a minimum weight rating of 2000  
pounds to block the unit up. Use in pairs only. Follow the  
instructions supplied with the vehicle stands.  
Do not touch hot parts of machine.  
Keep nuts and bolts tight, especially the blade attachment bolts.  
Keep equipment in good working condition.

penetrate skin. Hydraulic oil may 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. 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.  
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.  
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.  
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

Always place fuel containers on the ground away from your  
vehicle before filling.  
When practical, remove gas-powered equipment from the  
truck or trailer and refuel the equipment with its wheels on  
the ground. If this is not possible, then refuel such equipment  
on the truck or trailer using a portable container and not a fuel  
dispenser nozzle. If a gasoline dispenser nozzle must be  
used, keep the nozzle in contact with the rim of the fuel tank  
or container opening at all times until fueling is complete. Do  
not use a nozzle lock-open device.

A fuel shut-off valve is located on each tractor. The location and  
operation of the fuel valve will vary depending upon the unit. Close the  
fuel valve to prevent fuel flow to the engine. The valve’s two other  
positions will allow fuel to be drawn from either one or the other fuel tank.

Diesel units  
Read and observe safety precautions elsewhere in this  
manual.  
The fuel tanks are located in the tractor’s fenders. These engines  
requires number 2 diesel fuel only.  
Hustler Z Shibaura Diesel tractors are equipped with a fuel shutoff valve  
located to the right rear of the seat. Rotate the valve to the middle position  
to allow fuel to flow from the right fuel tank to the fuel pump. The right  
position prevents fuel flow to the fuel pump. The left position allows fuel  
to flow from the left fuel tank to the fuel pump. Close this valve to prevent  
fuel flow to the engine when servicing the fuel system or when transporting  
the unit on a trailer or truck. Fig. 4-4  
WARNING: Gasoline or diesel fuel is harmful or fatal if  
swallowed.  
Long-term exposure to vapors can cause serious injury and  
illness.  
Avoid prolonged breathing of vapors.  
Keep face away from nozzle and gas tank or fuel container  
opening.  
If the diesel fuel system runs dry, use the following procedure when re-  
starting the engine:  
Keep gas away from eyes and skin.  
If fuel is spilled on clothing, change clothing immediately.  
1. Refill the fuel tanks.  
2. Make sure the fuel shutoff valve is turned to the full fuel tank.  
3. Take the priming bulb and compress it until it becomes firm. Fig. 4-5  
4. Try and start the engine. If it will not start after 15 seconds of  
cranking, repeat Step 3.  
5. If after trying several tries, the engine still will not start, contact your  
Hustler Dealer.  
WARNING: Fuel System Under Pressure! The EFI 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, gasoline  
leakage and possible explosion.  
Gasoline units  
The fuel tanks are located in the tractor’s fenders.  
Engine oil and filter  
Check engine oil daily and after every 4 hours of operation. Tractor  
must be setting level when checking oil. Refer to engine manual and  
maintenance schedule for oil recommendation and capacities.  
Change the engine oil and filter after the first 5 hours of operation (50  
Use regular unleaded gasoline with an octane rating of 87 or higher.

hours on a Hustler Z Shibaura diesel unit), per the engine manufacturer’s  
recommendations after that. If tractor is being operated in extremely dirty  
conditions, then it is recommended oil be changed more frequently.  
Engine air filter  
Perform engine air filter maintenance per the Service Interval chart  
shown elsewhere in this manual.  
A specially designed dry filter is standard equipment on these tractors  
and supplies clean combustion air to the engine. Some examples of the air  
filter are shown in Fig. 4-6 & 4-7.  
Recommended service procedure  
Canister  
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.  
Figure 4-7  
3. Reinstall the dust cup. Make sure it seals all the way around the air  
cleaner body, then tighten the clamps.  
Safety filter  
4. Check all fittings and clamps periodically for tightness and inspect  
hoses for holes or cracks.  
5. Periodically check the intake hose for signs of ingested dust. Locate  
and repair the source of ingested dirt.  
6. Never operate a machine without an air filter installed.  
Safety filter  
Some Hustler tractors are equipped with a safety filter. The filter  
element slides over the safety filter.  
NOTE: The safety filter does not require servicing unless it becomes  
contaminated with dirt or moisture. Fig. 4-8  
Overservicing  
Overservicing occurs when an air filter element is removed for cleaning  
or replacement before it is necessary. Each time the filter is removed a  
small amount of dirt and dust could fall in the intake system. This  
accumulated dirt can cause a dusted engine. It only takes a few grams of  
ingested dirt over the normal service life of an engine to cause a dusted  
engine.  
Do not clean element, replace with a new element only. Cleaning  
used air filter elements, through improper cleaning procedures, can get dust  
on the inside of the filter causing dirt ingestion and engine failure.  
It is important to note that whenever an air filter element is cleaned by  
any method, the person or company performing the cleaning assumes  
responsibility for the integrity of the filter from then on. The warranty for  
air filters expires upon cleaning or servicing in any manner because the  
condition of the filter after servicing is completely out of their control.  
Therefore, on a dust ingested engine failure, there will be no warranty  
Figure 4-8  
consideration if the air filter element has been cleaned or serviced in  
any manner.  
A partially dirty air filter element works better than a new element.  
Therefore, a dirty filter element is not bad for the engine unless it is  
excessively restricting the air flow and engine performance is affected. The  
reason is simple. The media in the filter must be porous to allow air to pass  
through it. When dirty air passes through the filter, the dirt plugs some of  
the holes in the media and actually acts as part of the filter media. When  
the next round of dirt enters, the first dirt helps filter out even smaller  
particles making the filter more efficient at stopping dirt from entering the  
engine. This is referred to as barrier filtration.  
Of course, at some point the filter media becomes too clogged to allow

Engine cooling is accomplished with circulated water and Ethylene  
Glycol mixture. The radiator is equipped with a pressure cap and overflow  
reservoir. Follow the information found in the engine owner’s manual for  
the recommended coolant solution.  
Visually inspect the system daily prior to operating tractor. Be sure the  
engine is level. Check the coolant level only when the system is cold.  
Check the coolant level only at the overflow reservoir (Fig. 4-10). The  
cooling system is a closed type. Never open the radiator cap. Doing so  
may induce air into the cooling system and may cause overheating. The  
coolant level should be between the “H” and “L” marks.  
General engine maintenance  
Detailed instructions and recommendations for break-in and regular  
maintenance are specified in the Engine Owner’s manual. Please refer to  
this manual for engine servicing, lubricating oil levels with quality and  
viscosity recommendations, bolt torques, etc. The engine warranty is  
backed by the manufacturer. Special attention should be paid to applicable  
data which will not be duplicated here.  
IMPORTANT: Refer to the Kohler EFI engine owner’s manual for  
specific cleaning instructions.  
Belts  
Diesel Units  
Inspect belts frequently for wear and serviceability. Replace a belt that  
shows signs of severe cuts, tears, separation, weather checking and  
cracking, or burns caused by slipping. Slight raveling of belt covering does  
not indicate failure, trim ravelings with a sharp knife.  
DANGER: Never remove radiator cap or overflow reservoir  
cap when engine is hot. Pressurized hot steam and water may  
be released, causing serious burns or possible blindness. Fig.  
4-11  
WARNING: If the pump belt fails, loss of control will occur  
especially when operating on a slope. If you lose steering  
control while operating the machine, place the steering  
control levers in the park brake position immediately.  
Inspect the machine and involve your Hustler dealer to  
resolve the problem before continuing to operate.  
Engine cooling is accomplished with circulated water and Ethylene  
Glycol mixture. The radiator is equipped with a pressure cap and recovery  
tank. A 50-50 mixture is recommended for all season operation. This  
mixture provides freeze protection to -32 degrees F (-35 degrees C).  
Should temperatures fall below this level, additional Ethylene Glycol must  
be added to the mixture.  
Visually inspect the system daily prior to operating tractor. Check  
coolant level in the recovery tank located to the left rear of the engine (Fig.  
4-11). When the engine is cold the coolant should be up to the cold mark  
on the recovery tank. When the engine is hot the coolant should be up to  
the hot mark on the recovery tank. When adding coolant, pre-mix the  
solution before adding it to the recovery tank. It is not necessary to remove  
radiator cap for adding small amounts of coolant to system.  
Inspect the belt pulley grooves and flanges for wear. A new belt, or one  
in good condition, should never run against the bottom of the groove.  
Replace the pulley when this is the case, otherwise belt will lose power and  
slip excessively.  
Never pry a belt to get it on a pulley as this will cut or damage the fibers  
of the belt covering.  
Keep oil and grease away from belts, and never use belt dressings. Any  
of these will destroy the belt composition in a very short time.

Do not re-use spindle bolts which have stripped, worn or undercut  
threads. Torque bolts on spindles to 118 foot-pounds (160.0 Nm) when  
reinstalling blades.  
IMPORTANT: When mounting blades, rotate them after installation to  
ensure blade tips do not touch each other or sides of the mower.  
Mower blade maintenance  
Check the mower blades daily, they are the key to power efficiency and  
well groomed turf. Keep them sharp, a dull blade will tear rather than cut  
the grass, leaving a brown ragged top on the grass within a few hours. A  
dull blade also requires more power from the engine.  
Replace any blade which is bent, cracked or broken.  
WARNING: Failure to correctly torque the bolt may result in  
the loss of the blade which can cause serious injury.  
WARNING: Never attempt to straighten a bent blade by  
heating, or weld a cracked or broken blade as the blade may  
break and cause serious injury. Replace worn or damaged  
blades.  
WARNING: Mower blades are sharp and can cut. Wrap the  
blade(s) or wear gloves and use extra caution when servicing  
them.  
DANGER: Never work with blades while engine is running  
or deck clutch switch is engaged (on). Always place deck  
clutch switch in the disengaged position, place control levers  
in the park brake position and turn engine off and disconnect  
negative battery cable. Block up mower when you must  
work under it. Wear gloves when handling blades. Always  
check for blade damage if mower strikes rock, branch or  
other foreign object during mowing!  
Control lever adjustment  
The steering control levers can be adjusted for operator comfort. By  
loosening the cap screws that attaches the upper control lever to the lower  
lever (Fig. 4-15), the upper control lever can be pivoted to fit the operator’s  
personal preference.  
The steering control levers should be adjusted so that they align with  
each other when in the neutral position.  
WARNING: Always wear adequate eye protection when  
grinding mower blades.

Mower blade removal  
Use a 15/16" wrench to remove the 5/8" cap screw holding the blade to  
the spindle shaft from underneath. NOTE: A blade holding tool (part  
number 381442) is available from Hustler Turf Equipment. It is designed  
to prevent the blades from rotating when they are being removed or  
installed on the spindle. Contact your Hustler dealer for more information.  
Sharpen the blades on a grinder following pattern as shown (Fig. 4-12).  
Touch-up sharpening can be done with a file.  
Straight Blade  
Comparison of Warped and Straight Blades

Check the blades for balance following grinding. A commercial  
balancing tool is available through most hardware supply stores, or  
balancing can be done by placing the blade on an inverted line punch or  
1/2" bolt. Blade should not lean or tilt. Spin the blade slowly, blade should  
not wobble. If blade is out of balance, true it up before reinstalling.  
Lay the blade on a flat surface and check for distortion (Fig. 4-13 and  
4-14). Replace any distorted blade.

STORAGE  
Preparation of batteries for storage  
When the machine is to be unused for long periods, it is best to  
disconnect the batteries and remove them from the unit. At this time  
perform the following battery maintenance:  
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. Replace air filter element.  
1. Clean battery  
2. Check the electrolyte level  
3. Check thoroughly for any worn or damaged parts that need  
replacing and order them from your dealer.  
4. Thoroughly lubricate machine, according to lubrication instructions.  
5. Check hydraulic oil level. Add oil if necessary or change oil and  
filter if not done in last 500 hours. Refer to Maintenance section.  
6. Block tractor up so weight is off tires.  
3. Charge the battery, if necessary  
4. Store battery in a cool, dry place (do not expose to freezing  
temperatures)  
5. Always keep the battery fully charged. (Especially important to  
prevent battery damage when the temperature is below 32F.)  
NOTE: Do not deflate tires.  
7. Perform separate engine and battery preparation as listed below.  
8. Store tractor in a clean, dry place.  
New season preparation  
Before starting the tractor following post season storage, the following  
servicing is required:  
1. Clean tractor, removing trash and dirt accumulation.  
2. Check engine oil, hydraulic oil and coolant levels.  
3. Fill fuel tanks with fresh fuel. Bleed fuel system as outlined in  
Maintenance section. Run machine at half speed for 5 minutes,  
checking operation of steering control lever. Stop engine and check  
for oil leaks, loose fittings and so forth.  
Preparation of engine for storage  
When engine is to be unused for long periods, proceed as follows:  
1. Run engine for a minimum of 15 minutes.  
2. Drain oil from crankcase while engine is still warm.  
3. Refill with fresh oil of proper viscosity.  
4. Drain fuel tanks.  
5. Remove and replace fuel filter.  
6. Clean exterior surface of engine. Spread a light film of oil over any  
exposed metal surfaces of engine that are subject to corrosion.  
7. Check oil filler cap and fuel tank cap to make certain they are  
securely in place.  
WARNING: At start of new season always check that fresh  
oil and coolant have been added to machine. If oil and  
coolant are drained at season’s end and not replaced, engine  
damage will result.  
4. Tighten any bolts that have loosened and make sure all hair pins,  
cotter pins and clevis pins are in place.  
5. Install all safety shields and review safety precautions listed in this  
manual.  
6. Check and inflate tires to 8-12 psi (55-83 KPa).  
7. Install fully charged batteries and attach the battery cables.
