NOTICE OF REQUIREMENT OF SPARK ARRESTER MUFFLER
This equipment may create sparks that can start fires around dry vegetation. California Public Resources Code Sec-
tion 4442.6 provides that it is unlawful to use or operate an internal combustion engine on any forest-covered,
brush-covered, or grass-covered land unless the engine is equipped with a spark arrester maintained in effective
working order. A spark arrester is a device constructed of nonflammable materials specifically for the purpose of
removing and retaining carbon and other flammable particles over 0.0232 of an inch in size from the exhaust flow of
an internal combustion engine that uses hydrocarbon fuels or which is qualified and rated by the United States For-
est Service. Other states or federal areas may have similar laws. The Operator Should Contact Local Fire Agencies
For Laws or Regulations Relating to Fire Prevention Requirements. THIS EQUIPMENT DOES NOT HAVE A
SPARK ARRESTER AND YOU SHOULD CONTACT YOUR AUTHORIZED DEALER FOR THE PURCHASE OF A
SPARK ARRESTER.
Inspect spark arrester daily; replace every 500 hours or as needed.
The Engine Owner’s Manual provides information regarding the U.S. Environmental Protection Agency
(EPA) and the California Emission Control Regulation of emission systems, maintenance and warranty.

VAlways observe traffic laws while driving machine
from one location to another. Watch for traffic when
operating near or crossing roadways.
VAlways 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.
VInspect 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.
VAlways inspect machine for damage after striking a
foreign object. If damage is found, repair machine
immediately. Be sure to stop on level ground, place
park brake lever in the brake engaged position, place
the PTO lever in the “OFF” position, lower attachment,
remove ignition switch key before leaving operator’s
seat to inspect damage.
VNever engage the PTO Control Lever unless the PTO
shaft is securely connected to a power driven attach-
ment.
VAlways 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 head-
phones while operating the machinery. Safe operation
requires your full attention.
VDo not operate the equipment while wearing sandals,
tennis shoes, sneakers, shorts or any type of loose fit-
ting 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.
VAlways 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.
VNever push down suddenly on brake pedal while the
machine is in forward motion because machine may tip
forward causing loss of control.
VNever push down suddenly on the HST reverse pedal
while the machine is in forward motion because
machine may tip forward causing loss of control.
VNever drive the tractor at high speeds without a front-
end attachment mounted to the tool bars. Keep the

VAlways keep clear of the mower blades and attach-
ments during their operation.
VTurn off blades when not mowing.
VSlow down before turning.
VStop the engine before removing the grass catcher or
unclogging the discharge chute. Never clear the dis-
charge chute with the engine running. Turn off the

VDo not operate the machine while under the influence
of alcohol or drugs.
VExercise caution when loading or unloading the
machine onto a trailer or truck.
VAlways wear safety goggles or safety glasses with side
shields when operating the tractor.
VData 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.
VFollow the manufacturer’s recommendation for wheel
weights or rear counter-balance weights.
VIf any attachment or additional weight is mounted on
the front of the unit, any rapid movement of the HST

3-2 109627_0910
pedals in either direction could result in a reaction of
the tractor that can cause serious injury.
VWhen desconnection on attachment that uses the trac-
tor PTO output shaft to power the attachment, the pow-
ered shaft of device must also be disconnected from the
tractor PTO output shaft. Never leave an unsupported
PTO device attached to the tractor PTO output shaft, if
it is not completely and properly assembled to the
attachment on which it’s use is intended.
VClean 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.
Using a ramp
VUse extreme caution when loading and unloading a
unit onto a truck or trailer with a ramp.
VUse only a single, full width ramp; do not use individ-
ual 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.
VDo not exceed a 15 degree angle between the ramp and
the ground or between the ramp and the trailer or truck.
VWhen 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. REMINDER: Only operate
on slopes of 15 degrees or less.
VUse 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
• While driving on slopes, always run in AWD (All
wheel drive) locked position.
• Never make sudden changes in speed or direction.
• If it becomes necessary to turn downhill, turn slowly
and gradually, if possible.
VWatch for holes, ruts, bumps, rocks or other hidden
objects. Uneven terrain could overturn the machine.
Tall grass can hide obstacles.
VRemove obstacles such as rocks, tree limbs, etc.
VKeep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction.
VAvoid starting and stopping on a slope. If tires lose
traction, disengage the blades and proceed slowly
straight down the slope.
VMow a safe distance (minimum of 10 feet) away from
drop-offs, retaining walls, drainage ditches, embank-
ments, 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.
VUse 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 roll-
over and serious injury or death.
VDo not mow on wet grass. Reduced traction could
cause sliding and loss of steering control.
VIf the mower’s tires lose traction when operating on
slopes, disengage the blades, engage the park brake,
turn the engine off and get help.
VNever make sudden starts, stops, turns, or reverse
direction, especially when maneuvering on slopes.
The steering is designed for sensitive response. Rapid
movement of the steering wheel or HST foot pedals in
either direction could result in a reaction of the tractor
that can cause serious injury.
VNever stop suddenly while going down slopes. This
action may result in a reaction of the tractor that can
cause serious physical injury.
VThe Hustler mower is capable of operating horizontally
(traverse) on moderately steep slopes. When operating
on slopes up to 15 degrees, be aware of any conditions
that may cause the tractor drive tires to lose traction
resulting in a possible loss of control of the machine.
An operator should not operate on a slope until he is
thoroughly familiar with the equipment.
Do not operate on slopes greater than 15 degrees.
Refer to Slope Guide, page 2-7, when determining the
degree of slope to be mowed.
It is strongly recommended that the operator drive the
machine off of the slope, using extreme caution, if any
sign of loss of traction is detected. Wait until the con-
dition that caused the problem is resolved before
attempting to operate on the slope again.
Terrain conditions can affect traction resulting in possi-
ble loss of control of the machine. Some of the condi-
tions to be aware of are:
1. Wet terrain
2. Depressions in the ground; i.e. holes, ruts, washouts
3. Mounds of dirt
4. Soil type; i.e. sand, loose dirt, gravel, clay
5. Grass type, density, and height
6. Extremely dry conditions of grass
7. Tire pressure
The attachments mounted to the tractor will also affect
the way it handles on a slope. Be aware that each
attachment’s characteristics vary.
Do not tow on slopes. The weight of the towed equip-
ment may cause loss of traction and loss of steering
control.
Another consideration to safe mowing on slopes is to
be aware of what is located at the bottom of the slope.
Extreme caution should be used when there is a hazard
located at the bottom of the slope. Some examples are:
1. Water; i.e. lake, river
2. Cliffs, retaining walls
3. Roads, highways
4. Buildings
5. Rocks
These are just a few examples of situations when cau-
tion must be used when operating on a slope. There are

109627_0910 3-3
many other possibilities too numerous to mention.
Just remember to always exercise extreme caution
when operating on any slope.
VThe ROPS will minimize chance of injury or death
from rollover. Seat belt must be fastened while oper-
ating a machine equipped with ROPS in the raised
and secured position. Both retaining pins and hair
pins must be installed. Failure to use seat belt will
result in serious injury in the event of a roll over.
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.
VNever leave machine unattended with ignition key in
switch, especially with children present.
VChildren or bystanders may be injured if they move or
attempt to operate the tractor while it is unattended.
Always disengage PTO lever, engage park brake, stop
tractor engine, and remove ignition key when leaving
operator’s seat.
VKeep children out of the mowing area and under the
watchful care of a responsible adult other than the
operator.
VBe alert and turn the machine off if children enter the
area.
VBefore and while backing, look behind and down for
small children.
VNever 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.
VNever allow children to operate the machine.
VUse care when approaching blind corners, shrubs,
trees, the end of a fence or other objects that may
obscure vision.
VNever allow children or others in or on towed equip-
ment.
Instrument Panel
A. Electronic hour meter (Figure 3-1) — Registers 1/10
hour increments up to 9,999.9 total hours. Connected
to the ignition switch, the meter records the
accumulative time while the ignition key is switched
to the RUN position.
B. Temperature gauge and alarm (Figure 3-1) —
When the needle is in the middle area, the engine is at
its normal operating temperature. When the needle
reaches the “H” side of the gauge it indicates the
engine coolant has reached an unsafe temperature. If
this occurs, shut down the machine as soon as
possible. Never risk continued operation; high
temperatures can severely damage the engine.
The coolant temperature fluctuates depending on
ambient temperatures and working loads. If the needle
is at the “H” side during operation, the overheat alarm
buzzer sounds.

amount of fuel in the tank.
D. Glo-plug warning light (Figure 3-1) — Comes on
when turning the key switch to the “HEAT” position
or “START” position. This light will stay on for
approximately 5 seconds in the “HEAT” Position.
E. Oil pressure warning light and alarm (Figure 3-1)
—This light comes on when the ignition switch is
placed in the “RUN” position and stays lit until the
engine is running and a safe oil pressure is developed.
If light comes on during operation, shut engine off
immediately and locate and correct the problem.
When oil pressure falls below 4.25 psi (29.4 kPa), the
alarm buzzer will sound. IMPORTANT: The operator
must occasionally check the crankcase for proper oil
level.
NOTE: The alarm buzzer will sound when engine
stops with key left inserted at “RUN” position. In
order to stop the alarm buzzer, return the key to
“STOP” position.
F. Charge indicator warning light (Figure 3-1) — This
light comes on when the ignition switch is placed in
the “RUN” position and stays lit until the engine is
running. If it remains lit the charging system is not
operating normally. Investigate the cause as soon as
possible, otherwise the battery will fully discharge.
G. Air cleaner restriction warning light (Figure 3-1)
— When the air cleaner element is clogged by foreign
substances, such as dust, and clean air is restricted to
the engine, this light will illuminate. Refer to the
Engine Air Filter section of this manual for detailed
information.
H. Parking brake warning light (Figure 3-1) — When

ate in the Locked AWD mode.
H. PTO Control lever (Figure 3-11) — This lever
engages and disengages the PTO. Move the lever
forward and hold it to engage the PTO. Move the lever
rearward to disengage the PTO.
a. PTO must be in disengaged position to start the
engine ( See “PTO stop system:” on page3-7).
IMPORTANT: Do not repeatedly engage and dis-
engage the PTO when Mower becomes clogged.
Doing so may cause PTO clutch failure. If Mower
becomes clogged, stop the engine, remove starter
key and clean underside of deck using a probe, not
your hand.
IMPORTANT: When PTO lever is engaged and
operator raises the front attachment, if attachment
is raised all the way up, the PTO will automatically
be disengaged. This is a tractor safety feature!
I. Tool Bar Lift Control lever (Figure 3-11) — The
front mounted equipment can be raised and lowered by
the tool bar lift control lever. Place handle in the
forward position to lower and to the rearward position
to raise front mounted equipment.
To lower and float the equipment, push the lever
forward. To raise the equipment, pull the lever
rearward and hold it until the equipment is raised to the
desired position.
WARNING: To avoid personal injury, disengage
the PTO Control lever before operating the Tool Bar
Lift Control lever.
J. Weight Transfer Control (Figure 3-11) — This
feature enables the operator to transfer the weight of
the deck or other equipment to the tractor unit.
Turn the knob clockwise, the effort of weight transfer
is increased, refer to the Weight Transfer Valve section
for additional information.
Seat adjustment
The seat can be adjusted four different ways to obtain the
most comfortable position:
1. Back angle (Figure 3-12)
2. Forward and rearward travel (Figure 3-13)
3. Weight (Figure 3-13)
4. Lumbar (Figure 3-14)
Steering wheel adjustment
The 3500/3700 is equipped with an adjustable steering
wheel which can telescope and tilt.
To telescope the wheel, turn the wheel hub to the left and
raise or lower the steering wheel to the desired height. Then
turn the hub to the right to lock it into position. (Figure 3-15)
NOTE: When locking the hub into position, do not
overtighten.
To tilt the wheel, pull up on the lever and move the steering
wheel fore or aft the desired position. If the wheel is not held
in position when the lever is raised, the steering wheel will
spring to its most forward position. Use this feature to gain
additional clearance when mounting and dismounting the
tractor. (Figure 3-16)
Safety start interlock system
The tractor is equipped with a safety start interlock system
consisting of the brake switch, seat switch, PTO switch and
transmission neutral switch.
Check tractor safety start interlock system daily, prior
to operation. This system is an important tractor safety
feature. It should be repaired immediately if it malfunctions.
The machine incorporates a separate seat switch which will
stop the tractor engine when the operator is unseated for any
reason while the tractor is operating. This is a safety feature
designed to prevent runaway or accidental entanglement.
Raising off the seat, the engine will stop whenever
operating PTO driven equipment such as the mower deck.
Also the engine will stop when raising off the seat unless the
parking brake or master brake pedal is applied.
