 Always wear safety goggles or safety glasses with side
shields when operating this mower.
 Do not operate the mower if you are fatigued, sick or
while under the influence of alcohol or drugs, if you are
pregnant or under 18 years old.
 Poor posture or operating the mower for extended periods of time may lead to fatigue or injury, resulting in
loss of mower control. Occasionally, stop the mower
and get off the seat to stretch and relax.
 Data indicates that operators, age 60 years and above,
are involved in a large percentage of riding mowerrelated injuries. These operators should evaluate their
ability to operate the mower safely enough to protect
themselves and others from serious injury.
Operation
 Never leave a running mower unattended. Before leaving the operator’s seat for any reason, including emptying the catcher or unclogging the chute:
• Always stop on level ground.
• Disengage the deck clutch.
• Place the steering control levers in the park brake
position.
• Stop the engine.
• Remove the ignition key.
• Wait for the engine and all moving parts to come
to a complete stop.
 Always inspect mower for damage after striking a foreign object. If damage is found, repair mower immediately.
 Always remain seated while operating the mower. Only

• Never operate the machine with the floor plate
pulley cover removed.
 Never operate the mower deck with the discharge
chute damaged, altered, removed, or in the raised position, except when the entire grass catcher attachment
or mulching system is being used.
 Always keep clear of the mower blades and attachments during their operation.
• Never put hands or feet under any part of the
mower while it is running.
 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!
 Follow daily and weekly checklists, making sure hoses
are tightly secured and bolts are tightened.
• Never operate a poorly maintained mower.
 Clean flammable material from mower. Prevent fires by
keeping the engine compartment, top of the deck,
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.
 Prevent fires by keeping the engine and exhaust areas
clear of grass clippings and other debris. Do not back
mower into flammable materials.
• Allow the mower, especially the engine, to cool
before storing inside a building.
 Do not change the engine governor setting or over
speed the engine. Operating the engine at excessive
speed may increase the hazard of personal injury.
 Rapid movement of the steering control levers in either
direction could result in a reaction of the mower that
can cause serious injury.
• Never push forward suddenly on your steering
control levers while the mower is in rearward
motion because mower may tip backwards.
• Never pull back suddenly on your steering control
levers while the mower is in forward motion.
 Always be aware of what is behind the mower before
backing up. Never mow in reverse. Always look down
and behind before and while backing up.
• If mowing in reverse is unavoidable, push forward
slowly on the steering control levers and avoid
sudden movement.
 Slow down before turning.

one location to another. Watch for traffic when operating near or crossing roadways.
• Use care when approaching blind corners,
shrubs, trees, or other objects that may obscure
your vision.
604856 2-3 REV J
Using a Ramp
 Exercise extreme caution when loading and unloading
a mower 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 mower frame to contact if the unit starts to tip backwards. It also reduces
the risk of a wheel going off and the mower tipping
over.
 Do not exceed a 15 degree angle between the ramp
and the ground or between the ramp and the trailer or
truck.
 Avoid sudden acceleration when on a ramp.
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 the mower up the
slope or if you feel uneasy on the slope; 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 mower 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 mower 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.
 Watch for holes, ruts, bumps, rocks or other hidden
objects. Uneven terrain could overturn the mower. 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 mower 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
mower 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 mower rollover and serious injury or death.
 Do not mow on wet grass. Slippery conditions reduce
traction which could cause sliding and loss of steering
control.
 Do not tow on slopes. The weight of the towed equipment may cause loss of traction and loss of steering
control.
 Do not try to stabilize the mower 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, stop the engine, remove
ignition switch key, 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 mower that can cause
serious injury.
 Never stop suddenly while backing down slopes. This
action may result in a reaction of the mower 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 mower drive tires to
lose traction resulting in a possible loss of control of
the mower. 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 the Slope Guide, when determining the degree
of slope to be mowed.
It is strongly recommended that the operator drive the
mower 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 mower. Some of the conditions to be aware of are:
• Wet terrain
• Depressions in the ground; i.e. holes, ruts, washouts
• Mounds of dirt
• Soil type; i.e. sand, loose dirt, gravel, clay
• Grass type, density, and height
• Extremely dry conditions of grass
• Tire pressure
The attachments mounted to the mower will also
affect the way it handles on a slope. Be aware that
each attachment’s characteristics vary.
Another consideration to safe mowing on slopes is to
be aware of what is located at the bottom of the slope.
Extreme caution should be used when there is a hazREV J 2-4 604856
ard located at the bottom of the slope. Some examples
are:
• Water; i.e. lake, river
• Cliffs, retaining walls
• Roads, highways
• Buildings
• 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 mower
and the mowing activity. Never assume that children will remain
where you last saw them.
 Never leave the mower unattended with the ignition
key in the switch, especially with children present.
 Children or bystanders may be injured if they attempt
to move or to operate the mower while it is unattended. Always disengage the deck clutch, place the
control levers in park brake position, stop the engine,
and remove the ignition key when leaving the 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 mower 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 mower 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 mower.
 Never allow children to operate the mower.
 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.
Service Precautions
 Unless specifically required, DO NOT have the engine
running when servicing or making adjustments to the
mower.
• Park the mower on level ground.

604856 2-5 REV J
 Keep nuts and bolts tight, especially the blade attachment bolts. Keep equipment in good working 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.
 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

Safety Start Interlock System
The mower’s safety start interlock system consists of the
park brake switches, seat switch, and deck clutch switch.
IMPORTANT: Repair this important safety feature immediately if it malfunctions.
This safety feature prevents mower runaway or accidental
entanglement during operation.
Check the mower’s safety start interlock system daily,
prior to operation.
To inspect the system:
1. Sit on the seat when testing the seat switch.
2. Set both steering control levers in the park brake position.
3. Start the engine and allow it to warm up to operating
temperature.
4. With the deck clutch switch down and the steering
control levers in the park brake position, slowly raise
off of the seat. The engine should continue to run.
5. With the deck clutch switch up and/or the steering
control levers in the neutral position, slowly raise off of
the seat. The engine should stop.
6. If the engine fails to stop when:
• the deck clutch switch is up, or
• one or both of the steering control levers is in the
up (out of neutral position), and
• the operator is off the seat, then
• check the function of the seat switch. Replace
the seat switch if it is not operating properly (is
not opening or closing) and if the cause can not
be determined.
If you cannot locate the problem contact your Hustler®
Dealer.

Engine Starting
The mower’s safety start interlock system is also designed
to protect the operator and others from accidental injury due
to unintentional engine starting. The engine starting motor
will not engage until:
1. Steering control levers are in the park brake position.
2. Deck clutch switch is in the down (OFF) position.
NOTE: The operator’s seat is equipped with a separate
safety switch. If for any reason the operator should become
unseated when the steering control levers are not in the park
brake position (park brake switches are disengaged) or the
deck clutch switch is engaged the engine will stop.
The following steps are the correct procedures for starting
the engine. If difficulty is encountered, contact the Hustler®
Dealer in your area.
1. Before starting mower each day, perform daily preoperation checking. (See Safety Start Interlock System
section.)
2. Make sure the steering control levers are in the park
brake position and deck clutch switch is disengaged.
Only start the engine from the operator’s position.
3. Use the choke, if the unit is equipped with one, when
engine is cold, or if warm engine fails to start within 5
seconds of cranking. Avoid flooding and operate
engine without choking as soon as possible.
4. Set throttle at approximately 1/2 open position.
5. Insert key in ignition switch and rotate full clockwise
to engage starting motor. Release key when engine
starts.
IMPORTANT: The engine starter should not be operated for periods longer than 30 seconds at a time. An
interval of at least two minutes should be allowed
between such cranking periods to protect the starter
from overheating and burn-out.
6. Perform test to make sure safety start interlock system is operating properly. Refer to Safety Start Interlock System section.
7. Allow the engine to idle a few minutes before advancing the throttle and/or engaging the deck clutch.
Stopping the Engine
Use the following procedure to shut the engine off.
1. Place the steering control levers in the park brake position.
2. Throttle the engine back to low idle, then disengage
the deck clutch. Refer to the Mower Deck Operation section for more details.
3. Let the engine run at low idle for two minutes.
4. Rotate the ignition key counter-clockwise to the “OFF”
position. Remove the key from the switch before leaving the mower.
Moving the Mower With Stalled Engine
The bypass valves on the transaxles allow the mower to be
moved if the engine quits working.
Before moving the unit, pull out on the bypass valve rod
(Figure 3-6) until the notch in the rod hooks over the edge of
the slot. This places the bypass valves in the disengaged
position.
Place the steering control levers in the neutral position, to
release the park brakes, so that the mower can be moved.
Do not tow the machine. Move it by hand or use a winch to
load onto a trailer for transporting.
Secure the mower, facing forward, when transporting on
another vehicle. Tie the mower down securely using straps,
chains, cables, or ropes. Both front and rear straps should be
directed down and outward from the machine.
IMPORTANT: Always make certain the two bypass valves
are returned to their operating position before running the
mower following repairs.

Driving the Mower
After starting the engine, engage the steering control
levers and steer as follows:
To go forward, push the steering control levers forward an
equal distance. Figure 3-7
To go in reverse, pull the steering control levers rearward
an equal distance. Figure 3-7
To turn left, move the right steering control lever farther
forward from neutral than the left steering control lever.
To turn right, move the left steering control lever farther
forward from neutral than the right steering control lever.
Figure 3-7
Zero radius turn, move one steering control lever forward
and the other steering control lever back of neutral. This
allows the drive wheels to counter-rotate. Figure 3-7
To stop or decrease speed, move steering control levers to
neutral. When going forward pull back gently on steering control levers. When going in reverse push forward gently on
steering control levers.
For emergency stops, when traveling forward or rearward,
place the steering control levers in the park brake position
immediately.
To make a three point turn to the right:
1. Move the left steering control lever farther forward
from neutral than the right steering control lever and
start the turn. Figure 3-8
2. Next, pull back on the steering control levers until they
pass neutral and the machine starts to go rearward.
Figure 3-8
3. Pull the right steering control lever farther rearward
from neutral than the left steering control lever until
the rear of the machine pivots around. Figure 3-8
4. Then, push the steering control levers forward until
they both pass neutral and the machine starts to go
forward. Figure 3-8
5. Push the left steering control lever farther forward
from neutral than the right steering control lever and
finish the turn. Figure 3-8
IMPORTANT: Damage to the hydraulic system components may occur with rapid movement of the steering controls.
To increase speed, increase the steering control lever’s distance from neutral. The farther forward the steering control
levers are from neutral, the faster the mower will travel forward. The farther back the steering control levers are from
neutral, the faster the mower will go in reverse.

Operating Suggestions
Inexperienced operators may have a tendency to oversteer
and lose control. Practice slow maneuvers at low engine rpm
(idle) on a flat open area before attempting normal speed
operation.
When turning on soft wet turf, keep both wheels rolling
either forward or backward. Pivoting on one stopped wheel
can damage turf, especially when mowing.
Set the throttle at full rpm for maximum performance. This
gives maximum power to the drive wheels and deck when
needed. The throttle setting directly controls blade speed.
Use the control levers to control ground speed rather than
engine rpm.
Keep blades sharp. 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. Blade sharpness
should be checked daily.
Direct grass discharge to the right, away from the
unmowed area. Generally, this means using a pattern of left
turns. Avoid throwing grass discharge onto unmowed area.
Mowing clippings puts an unnecessary load on the unit and
reduces mowing efficiency.
When mowing a lawn for the first time cut grass slightly
longer than normal to avoid scalping uneven terrain. When
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.
Alternate the mowing direction to keep the grass growing
straight and for better dispersion of the clippings.
Remember, grass grows at different rates at different
times of the year. Mow more often in the early spring to
maintain the same cutting height. As the growth rate slows
in midsummer, mow less frequently. If you cannot mow at a
regular interval, mow at a high cutting height; then mow
again two days later at a lower cutting height.
Raise the cutting height of the mower if the cutting width
of the mower is wider than the previous mower. This ensures
that uneven turf is not cut too short.
Raise the cutting height of the mower if the grass is
slightly taller than normal or if it contains a high degree of
moisture. Then mow it again with the cutting height set
lower.
If the machine’s forward motion must be stopped while
mowing, a clump of grass clippings may drop onto your lawn.
To avoid this, move onto a previously cut area with the
blades engaged.
An inexperienced operator should not mow on
slopes or on uneven terrain.
Before attempting normal speed operation an inexperienced operator should:
• be thoroughly familiar with the proper use
and operation of the equipment.
• read the manual completely and thoroughly.
• have attempted slow moving maneuvers.
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.
The unit’s steering control levers are very responsive: Easy does it! For smooth operation, move the
levers slowly, avoiding 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.
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.

Block the mower up when you must work under it.
Wear gloves when handling blades.
Always check for blade damage if the mower
strikes a rock, branch or other foreign object during mowing!
Never direct the discharge of material from the
mower deck toward bystanders.
• Never operate the mower deck with the discharge chute damaged, altered, removed, or

Deck Clutch Operation
Before beginning operation, check to make sure the deck
clutch switch is engaging and disengaging the blades properly.
To check the deck clutch switch:
1. Start the engine and engage the deck clutch.
2. With the deck clutch switch up (clutch engaged) and
the engine running, listen to confirm that the mower
blades are rotating.
3. Now, push the deck clutch switch down (clutch disengaged), and with the engine running, listen to confirm
that the blades have stopped rotating.
4. If the mower blades continue to rotate with the deck
clutch switch down, discontinue operation immediately and contact your Hustler® Dealer.
Follow these procedures to maximize clutch life.
1. Engage the clutch only when the throttle is set at
approximately 2/3 throttle and there is no load on the
blades. After clutch engagement, advance the engine
throttle to full rpm.
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.
2. Disengage the clutch only when the throttle is set at
less than 1/2 throttle.
Never disengage the clutch with the engine running at
high rpm. Setting the throttle to less than 1/2 throttle
when disengaging the clutch will help extend clutch life.
Warranty will not be allowed for deck clutches that fail due
to improper engagement and disengagement practices.
Deck Cutting Height Adjustment
Deck cutting height is adjustable in 1/4” (6.4mm) increments.
Step on the deck lift pedal and latch the transport lever in
the deck transport position. Pull the adjusting pin out of the
hole that it is in and insert it into the desired cutting height
hole. Step on the deck lift pedal to release the transport
lever. Figure 3-10
Step on the deck lift pedal and raise the deck to its highest
position and latch the transport lever in place when transporting the unit. Figure 3-10
Anti-Scalp Wheels
Anti-scalp wheels are standard on these mowers. These
wheels are designed to minimize scalping when mowing on
rough uneven terrain. Figure 3-11
Anti-scalp wheels can be installed in two positions. With
the wheel installed in the bottom hole, the wheel is located

MAINTENANCE & ADJUSTMENTS
Safe Servicing Practices
Refer to the Safety section of this manual for more detailed
service safety information.
Service 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. For more detailed information order the correct Parts
Manual and General Service Manual for your unit. Refer to the
Product Literature section of this manual.
Remain alert for unusual noises, which could signal a problem. Visually inspect the machine for any abnormal wear or
damage. A good time to detect potential problems is while
performing scheduled maintenance service. Correcting the
problem as quickly as possible is the best insurance.
Clear away heavy build-up of grease, oil and dirt, especially
in the engine and under the seat platform areas; minute dust
particle are abrasive to close-tolerance engine and hydraulic
assemblies.
Inspect mower daily for grass clippings and wire or string
tangles. The underside of the mower deck will collect a buildup 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. Scrape the
build-up from underneath.
IMPORTANT: Seat arm rests – Place the steering control
levers in the park brake position and pivot the arm rests
upward before lifting the seat platform to prevent arm rest
damage.
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.

Master In-Line Fuse
These mowers have a master in-line fuse in the electrical
system. This is the main fuse to protect the complete electrical system. It is located under the seat platform and next to
the solenoid. Figure 4-1
Hydraulic System
This mower is equipped with two integrated hydrostatic
transmissions. Figure 4-2
IMPORTANT: Never use hydraulic or automatic transmission fluid in this system; use only motor oil as specified.
Remember, dirt is the primary enemy of any hydraulic system.
The hydraulic expansion tank is located in front of the
engine and under the operator’s platform. Figure 4-2
Check oil level in hydraulic system after every 50 hours of
operation or weekly, whichever occurs first. Check more
often if system appears to be leaking or otherwise malfunctioning.
Fluid level should be at the “Full Cold” line on the expansion tank. Use only SAE 20W50 service motor oil.
Initial system oil and filter change must be after the first 75
hours of use or 1 year whichever comes first. Thereafter,
replace filter and oil in each transmission every 2 years or
200 hours, whichever comes first. NOTE: The filter guard
must be removed to access filter.
Each transmission’s filter is located per Figure 4-3. A standard oil filter wrench is used to change filter, threads are
right handed. Use a Hustler® approved filter element only.
Fuel and Evaporative Emissions Control System
IMPORTANT: Refer to the Safety section of this manual for
fuel handling safety information.
The fuel and evaporative emissions control system for this

Fuel Evaporation System Filter
These mowers have a fuel evaporation system filter. This
filter must be checked and replaced every 100 hours or annually whichever comes first. Figure 4-6 & Figure 4-7
Carbon Canister
Some Hustler® Raptor® SD mowers have a carbon cannister incorporated into the fuel system. Figure 4-8
This is a mandatory feature on all mowers using gasoline
engines that are put into operation in California.
This canister should be replaced every 5 years or if it
becomes damaged.
Engine Oil and Filter
Check engine oil daily and after every 4 hours of operation.
Mower must be on a level surface 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 and then per the engine manufacturer’s recommendations after that. If mower is being operated in extremely
dirty conditions, then it is recommended oil be changed more
frequently.
IMPORTANT: After the new oil filter has been installed,
clean up any oil which may have spilled onto the engine
plate, muffler, and heat shield.
Draining the engine oil:
1. Locate the oil drain valve on the lower right side of the
engine.
2. Locate the oil drain hose that was supplied with the
machine. Be sure to clean and clear it of debris that
might block the flow of the engine oil. Figure 4-9 &
Figure 4-10
3. Attach one end of the hose onto the oil drain valve nipple. Make sure the hose is pushed all the way onto the
valve. Figure 4-9 & Figure 4-10

4. Position the loose end of the hose forward and down
in front of the right side transmission so that it can
drain into a suitable oil drain container.
5. With the hose in position, use a 10 mm wrench or
socket and open the valve approximately 4 turns in the
counterclockwise direction. Allow 10 minutes for
engine oil to adequately drain.
6. After oil is drained, close the valve by turning it in the
clockwise direction until it is fully closed.
7. Once the valve is closed, carefully remove the oil drain
hose and clean up any spilled oil.
IMPORTANT: All oil drips or spills must be cleaned off
of the exhaust system before operating the machine.
8. Clean the oil drain hose and store it appropriately.
Figure 4-9 & Figure 4-10
Engine Air Filter
Perform engine air filter maintenance per the Maintenance
Schedule shown elsewhere in this manual.
General Engine Maintenance
Detailed instructions and recommendations for break-in
and regular maintenance are specified in the Engine Owner’s
Manual. Please refer to this manual for engine servicing,
lubricating oil levels with quality and viscosity recommendations, bolt torques, etc. The engine warranty is backed by the
manufacturer. Special attention should be paid to applicable
data which will not be duplicated here.
Belts
Inspect belts frequently for wear and serviceability.
Replace a belt that shows signs of:
• severe cuts
• tears
• separation
• weather checking
• cracking
• burns caused by slipping.
Slight raveling of belt covering does not indicate failure,
trim ravelings with a sharp knife.
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 the 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.

Refer to the Mower Blade Replacement section for blade
removal and installation.
Check the mower blades daily, they are the key to power
efficiency and well groomed turf. Keep the blades 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.
Sharpen the blades following the pattern shown.
Figure 4-11 Touch-up sharpening can be done with a file.
After grinding the blades, check for balance. Blade balancing can be done by placing the blade on an inverted line
punch or 5/8" bolt. A commercial balancing tool is also available through most hardware supply stores.
The blade should not lean or tilt. When spinning the blade
slowly it should not wobble. Balance the blade before reinstalling.
Lay the blade on a flat surface and check for distortion
(Figure 4-12 & Figure 4-13). Replace any distorted blade.
Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution
when servicing them.
Always check for blade damage:
• if mower strikes a rock, branch or other foreign object during mowing!
• or if an abnormal vibration occurs while operating.
Make all necessary repairs before resuming operation.

Mower Blade Replacement
IMPORTANT: Refer to the Safety section of this manual for
blade handling safety information.
A 15/16" wrench is required to remove the 5/8" cap screw
holding the blade to the spindle shaft. 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.
Do not re-use spindle bolts which have stripped, worn or
undercut threads. Torque bolts on spindles to 118 ft-lbs
(160.0 N•m) when reinstalling blades.
Properly compressed cup washers maintain the correct
compression load on the blades. Replace the cup washers if
they are cracked or flattened.
IMPORTANT: The blade sail (curved part) must be pointing upward toward the inside of the deck to ensure proper
cutting.
When mounting blades, rotate them after installation to
ensure blade tips do not touch each other or sides of the
mower.
Seat Adjustment
The seat on the Hustler® Raptor® SD mower can be
adjusted forward and rearward by pivoting the seat platform
up and forward. Then, loosen the four cap screws on the
underneath side of the seat platform. Position the seat where
you have the best control of the machine and are the most
comfortable and then tighten the cap screws. Figure 4-14
Steering Control Lever Adjustment
The steering control levers can be adjusted for operator
comfort.
A. To pivot the upper control levers forward or rearward,
loosen the cap screws that attach the upper control
lever to the lower lever. Then, pivot the upper control
lever. Tighten the cap screws. Figure 4-15
B. To lower and raise the control levers, remove the cap
screws. Slide the upper control lever up or down and
align the holes in it with the holes in the lower lever.
Re-install the cap screws and tighten.
The steering control levers should be adjusted so that they
align with each other when in the neutral position.
Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution
when servicing them.
Failure to correctly torque the bolt may result in
the loss of the blade which can cause serious
injury.

STORAGE
When storing the unit at the end of the mowing season, the
mower, engine, and battery should have the following items
serviced before storage.
If the mower has been stored for an extended period of
time, follow the new season preparation steps before beginning operation.
General Mower Preparation For Storage
1. Remove all grass, dirt, and trash from mower and cutting units.
IMPORTANT: Wash the machine with a mild detergent
and water. Do not pressure wash the machine. Avoid
excessive use of water, especially near the control
panel and engine.
2. Clean mower and deck and touch up all scrapes with
touch-up paint.
3. Install new air filter per Engine Owner’s Manual.
4. Check thoroughly for any worn or damaged parts that
need replacing and order them from your dealer.
5. Thoroughly lubricate machine, according to the Maintenance section.
6. Block mower up so weight is off tires. Check tire pressure and inflate to proper operating pressure.
NOTE: Do not deflate tires.
7. Perform separate engine and battery preparation as
listed below.
8. Store mower in a clean, dry place.
Preparation Of Engine For Storage
When the engine is to be unused for long periods, proceed
as follows:
1. Run the engine for a minimum of 15 minutes.
2. Drain the oil from the crankcase while the engine is
still warm.
3. Refill with fresh oil of the proper viscosity.
4. Drain the fuel tank and run the engine until it stops
from lack of fuel. Gasoline evaporates if left in the carburetor for long periods, forming gum and varnish
deposits in the 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. Remove the spark plugs and pour a tablespoon of
engine oil into each spark plug hole. Install plugs, but
do not reconnect plug leads.
7. Crank the engine with the starter at least a dozen revolutions to distribute oil over the cylinder walls and
valve mechanism.
8. Clean the exterior surface of the engine. Spread a light
film of oil over any exposed metal surfaces of the
engine that are subject to corrosion.
9. Clean dirt and chaff from the cylinders and fins, blower
housing and muffler.
10. Check the oil filler cap and fuel tank caps to make certain they are securely in place.
11. Refer to the engine manual for more information.
Preparation Of Battery For Storage
When the machine is to be unused for long periods, it is
best to disconnect the battery and remove it from the unit. At
this time perform the following battery maintenance:
1. Remove the battery from machine.
2. Clean the battery, terminals, and cable connectors.
3. Charge the battery, if necessary.
4. Store the 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 32°F (0°C).
New Season Preparation
Before starting the mower following post season storage,
the following service is required:
1. Clean mower, removing trash and dirt accumulation.
2. Check engine oil and hydraulic oil levels.
3. Install fully charged battery and attach the battery
cables.
4. Fill fuel tank(s) with fresh fuel. 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.
5. Tighten any bolts that have loosened and make sure
all hair pins, cotter pins and clevis pins are in place.
6. Install all safety shields and review safety precautions
listed in this manual.
7. Check and inflate tires to 8–12 psi (55–83 KPa).
