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/mechanic
should follow on a routine basis.
Remain alert for unusual noises, they could be signaling a problem.
Visually inspect the machine for any abnormal wear or damage. A good
time to detect potential problems is while performing scheduled
maintenance service. Correcting the problem as quickly as possible is the
best insurance.
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.
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.
Some repairs require the assistance of a trained service mechanic and
should not be attempted by unskilled personnel. Consult your Hustler
service center when assistance is needed.
Torque values
WARNING: Particular attention must be given to tightening the
drive wheel lug nuts and blade spindle bolts. Failure to correctly
torque these items may result in the loss of a wheel or blade,
which can cause serious damage or personal injury.
It is recommended that these be checked after the first 2 hours of
operation, initially and every 50 hours following removal for repair or
replacement.
For all other torques refer to the torque callout chart located elsewhere
in this manual.
For engine torque values, see engine owner’s manual.
Tires
It is important for level mowing that the tires have the same amount of
air pressure. The recommended pressures are:
Solid fill tires are not recommended for Hustler turf equipment. On
any machine, with solid filled tires, the warranty claim will be denied.
WARNING: Explosive separation of a tire and rim can cause
serious injury or death.
Do not attempt to mount a tire without the proper equipment and
experience to perform the task.
Always maintain the correct tire pressure and never over inflate.
Never weld or heat a wheel and tire assembly as an explosion
may occur. Welding can weaken or deform a wheel.
When inflating tires stand to one side and not in front of or over
the tire assembly.
Check tires for low pressure, blemishes, damaged rims or missing
lug bolts and nuts.
Lubrication
1. Grease the front gauge wheel bearings per the Maintenance
Schedule. Use SAE multi-purpose grease.
2. Grease the four deck lift pivots, located to the side of the
operator’s footrest per the Maintenance Schedule. Use SAE
multi-purpose grease.

allow air to be purged from the system. As this occurs, the oil level
will drop.
11. With both bypass valves closed (Fig. 9-11) and the engine running,
slowly move both control levers forward and rearward 5 - 6 times.
Stop engine and place steering levers in the park brake position.
Lower the tractor and check the oil level. Add oil as required.
12. Start the unit and drive it forward and rearward 5 times
approximately 10 - 20 feet each time.
If it feels smooth then the unit is ready to operate.
If either side moves slower than the other or sluggish then the
system will need to be purged again. Follow steps 9 through 12
WARNING: When washing the mower, direct spray away
(especially if using a power washer) from the Hydro-Gear C-IZT
transmission’s seals to prevent water intrusion and to ensure
component performance.
Fuel system
DANGER: Observe usual fuel handling precautions:
Do not smoke while refueling.
Do not fill tank with engine running or while engine is hot. Clean
up any gasoline spills.
Allow engine to cool before storing machine inside a building.
Keep fuel away from open flame or spark and store machine
away from open flame or spark if there is fuel in the tank.
Use extra caution when handling gasoline and other fuels. They
are flammable and vapors are explosive. A fire or explosion from
gasoline can burn you and others and can damage property.
Refuel outdoors preferably, or in well ventilated areas.
Never attempt to start engine when there is a strong odor of
gasoline fumes present. Locate and correct cause.
Store gasoline in an approved container and keep it out of the
reach of children. Never buy more than a 30 day supply of
gasoline.
Always place gasoline containers on the ground away from your
vehicle before filling.
Do not fill gasoline containers inside a vehicle or on a truck or
trailer as interior carpets or plastic truck bed liners may insulate
the container and slow the loss of any static charge.
When practical, remove equipment from the truck or trailer and
refuel the equipment with its wheels on the ground. If this is not
possible, then refuel the equipment on the truck or trailer using a
portable container and not a gasoline 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.
WARNING: Gasoline 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 conditioner opening.
Keep gas away from eyes and skin.
The fuel tanks are located in the tractor’s fenders. (Fig. 9-12) Total
capacity for the fuel tanks is 12.2 U.S. gallon (46.18 liter).

cap and remove the cap and begin filling. When finished, screw the cap on
securely and wipe up any spilled gasoline.
Use regular unleaded gasoline with an octane rating of 87 or higher.
IMPORTANT: Never use methanol, gasoline containing methanol, or
gasohol containing more than 10% ethanol because the fuel system could be
damaged. Do not mix oil with gasoline.
Using a fuel stabilizer/conditioner in the tractor can provide benefits
such as:
1. Keeps gasoline fresh during storage of 90 days or less. For longer
storage, drain the fuel tanks.
2. Cleans the engine during operation.
3. Eliminates gum-like varnish buildup in the fuel system.
IMPORTANT: Do not use fuel additives containing methanol or
ethanol.
Add the correct amount of gas stabilizer/conditioner to the gas. Follow
the gas stabilizer/conditioner manufacturer’s directions for best results.
The fuel filter (Fig. 9-13A, 9-13B & 9-13C) is installed in the fuel line
between fuel tanks and engine fuel pump on the rear left side of the engine.
Replace filter annually or after every 100 hours of operation, whichever
occurs first. For fuel filter removal refer to the engine owner’s manual
When replacing the fuel filter, check the fuel line hoses and fuel shutoff valve grommet for any cracks or leaks. Replace as needed.
Fuel Shut-off Valves
On early units a fuel shut-off valve is located on the outlet port of each
fuel tank. (Fig. 9-14) Close these valves (turn clockwise) to prevent fuel
flow to the engine. To drain a fuel tank equipped with this fuel shut-off
valve use the following method:
1. Park the unit on a flat surface. Stop the engine and remove the
ignition key. Make sure deck clutch switch is in the down (OFF)position. Place control levers in the park brake position.
Disconnect negative battery cable.
2. Close the fuel shut-off valve on both of the fuel tanks.
3. Trace the fuel line from the shut-off valve to the tee. Loosen the
hose clamp and remove the fuel line from the tee.
4. Place the end of the fuel line in a clean certified fuel container and
open the fuel shut-off valve to drain the fuel from the fuel tank.
5. When fuel tank is drained re-route the fuel line to the tee and attach
to the tee. Clamp fuel line to tee.
6. Fill fuel tank with proper grade of gasoline and open shut-off valves.
Current production units have a fuel shut-off valve (Hustler p/n
745059) located behind the seat to the right side of the operator. (Fig. 9-15)
Close this valve (center position) to prevent fuel flow to the engine. The
valve’s two other positions are front and rear. To drain a fuel tank equipped
with this fuel shut-off valve kit use the following method:
1. Park the unit on a flat surface. Stop the engine and remove the
ignition key. Make sure deck clutch switch is in the down (OFF)position. Place control levers in the park brake position.
Disconnect negative battery cable.
2. Turn the fuel valve to the closed position (middle position). Fig. 915
3. Disconnect the tank to fuel valve line from the valve and clamp or
cap the end of it.
4. Route the fuel line until it is lower than the fuel tank fitting.
5. Place the end of the fuel line in a clean certified fuel container and

Engine oil and filter
Check engine oil daily and after every 4 hours of operation. Crankcase
dipstick and oil filler tube are located as shown in Fig. 9-16A, 9-16B & 916C. Tractor must be setting level when checking oil. Refer to engine
manual and maintenance schedule for oil recommendation and capacities.
Change the engine oil and filter after the first 5 hours of operation, per
the engine manufacturer’s recommendations after that. If tractor is being
operated in extremely dirty conditions, then it is recommended oil be
changed more frequently.
The oil drain and oil filter are located at the rear of the engine. Fig. 9-
16A, 9-16B & 9-16C
Belt replacement
Figures 9-17 and 9-18 show diagrams and descriptions of the unit’s belt
drive systems.
Inspect these belts frequently for wear and serviceability. Replace a belt
that shows signs of severe cuts, tears, separation, weather checking and
cracking, or burns caused by slipping. Slight raveling of belt covering does
not indicate failure, trim ravelings with a sharp knife.
WARNING: If the pump belt fails, loss of control will occur
especially when operating on a slope. If you lose steering
control while operating the machine, place the steering
control levers in the park brake position immediately.
Inspect the machine and involve your Hustler dealer to
resolve the problem before continuing to operate.
Inspect the belt pulley grooves and flanges for wear. A new belt, or one
in good condition, should never run against the bottom of the groove.
Replace the pulley when this is the case, otherwise belt will lose power and
slip excessively.
Never pry a belt to get it on a pulley as this will cut or damage the
fibers of the belt covering.
Keep oil and grease away from belts, and never use belt dressings. Any
of these will destroy the belt composition in a very short time.
Deck belt replacement
1. Park the unit on a flat surface. Stop the engine and remove the
ignition key. Make sure deck clutch switch is in the down (OFF)position. Place control levers in the park brake position.
Disconnect negative battery cable.
2. Place the deck in the lowest position.

Mower blade maintenance
Check the mower blades daily, they are the key to power efficiency and
well groomed turf. Keep them sharp, a dull blade will tear rather than cut
the grass, leaving a brown ragged top on the grass within a few hours. A
dull blade also requires more power from the engine.
Replace any blade which is bent, cracked or broken.
WARNING: Never attempt to straighten a bent blade by heating,
or weld a cracked or broken blade as the blade may break and
cause serious injury. Replace worn or damaged blades.
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!
WARNING: Always wear adequate eye protection when
grinding mower blades.
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!
Mower blade removal
Use a 15/16" wrench to remove the 5/8" cap screw holding the blade to
the spindle shaft from underneath.
Sharpen the blades on a grinder following pattern as shown (Fig. 9-20).
Touch-up sharpening can be done with a file.
Check the blades for balance following grinding. A commercial
balancing tool is available through most hardware supply stores, or
balancing can be done by placing the blade on an inverted line punch or
5/8" bolt. Blade should not lean or tilt. Spin the blade slowly, blade should
not wobble. If blade is out of balance, true it up before reinstalling.
Lay the blade on a flat surface and check for distortion (Fig. 9-21 and 9-
22). Replace any distorted blade.
Do not re-use spindle bolts which have stripped, worn or undercut
threads. Torque bolts on spindles to 118 foot-pounds when reinstalling
blades.
IMPORTANT: The blade sail (curved part) must be pointing upward
toward the inside of the deck to ensure proper cutting.
WARNING: When mounting blades, rotate them after
installation to ensure blade tips do not touch each other or sides
of the mower.
WARNING: Failure to correctly torque the bolt may result in the
loss of the blade which can cause serious injury.
WARNING: Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution when servicing
them.

ADJUSTMENTS
Introduction
Your FasTrak 44/52 was adjusted before it left the factory and was
checked during predelivery setup. However, after start-up and continued
use, a certain amount of break-in wear will cause some adjustments to
change.
Remain alert for unusual noises, they could be signaling a problem.
Visually inspect the machine for any abnormal wear or damage. A good
time to detect potential problems is while performing scheduled
maintenance service. Correcting the problem as quickly as possible is the
best insurance.
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.
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.
Seat adjustment
The seat can be adjusted forward and rearward by removing the two cap
screws that lock the seat platform in place and pivoting the seat platform up
and forward. Then loosen the four cap screws on the underneath side of the
operator’s platform. Position the seat where you have the best control of
the machine and are the most comfortable and then tighten the cap screws.
Fig. 9-23
Control lever adjustment
The control levers can be adjusted for operator comfort. By loosening
the cap screws that attaches the upper control lever to the lower lever (Fig.
9-24), the upper control lever can be pivoted to fit the operator’s personal
preference.
The control levers can also be adjusted up and down. Remove the cap
screws and slide the upper control lever up or down and align the holes in it
with the holes in lower lever. Re-install the cap screws and tighten.
The control levers should be adjusted so that they align with each other
when in the neutral position.
Steering linkage
The neutral adjustment for the control levers in the neutral position is
discussed in this section.
The tractor steering has been factory adjusted to eliminate creeping
when the control levers are in the neutral position (Fig. 9-25). However,
should the tractor begin to creep, the control lever linkage can be adjusted
as follows:
Control Lever Neutral Adjustment
Before considering any adjustment, check the tire air pressure. Unequal
tire pressure will cause the tractor to drift to one side. Refer to tire pressure
information in the Maintenance section of this manual.
Fine adjustment to the unit’s steering is made with the adjustable pump
linkage rods. Fig. 9-26
Neutral is properly adjusted when the control levers are in the neutral
position and the drive wheels are not turning.
If the tractor creeps in the neutral position the control linkage may be
adjusted as follows:
1. Raise and block the tractor up so the drive wheels are off of the
floor.
WARNING: 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 onlycertified 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.
2. Position the control lever in the neutral position. Disengage the
deck clutch switch Fig. 9-25.
3. Loosen the nut on the steering dampener’s rear ball stud. Fig. 9-26
4. Remove the cotter key that connects the brake link to the brake
pawl. Remove the brake link from the brake pawl. Fig. 9-30
5. Start the engine and observe which way the wheels are rotating.
6. If wheel(s) are rotating forward, loosen the jam nuts on the pump
linkage rods and rotate the rod to lengthen the steering control
linkage until the wheel(s) come to a stop. Fig. 9-26
NOTE: The left linkage controls the left integrated pump/motor and
the right linkage controls the right integrated pump/motor.
Repeat for the opposite side if necessary.

If wheel(s) are rotating in reverse then loosen the jam nuts on the
pump linkage rods and rotate the rod to shorten the steering control
linkage until the wheel(s) come to a stop. Fig. 9-26
Repeat for the opposite side if necessary.
7. When both wheels remain in neutral, tighten the jam nuts to lock the
pump linkage rod in place.
8. Test again by moving the control levers forward and backward
before returning them to the neutral position. If the tires remain in
neutral, the unit is now ready for operation.
9. Shut the engine off. Place the control levers in the neutral position
and reconnect the brake link to the brake pawl. Re-insert the cotter
key. Fig. 9-30
10. Re-tighten the steering dampener’s rear ball stud after adjusting the
dampener per the following instructions:
Steering dampener
The steering dampener (Fig. 9-27) is spring loaded to return the control
levers to the neutral position from the reverse position. This gives the
operator a sense of neutral during operation.
If the tractor does not return to neutral from reverse then adjust as
follows:
To set the steering dampeners in the correct operating position follow
these steps:
1. Shut engine off, place control levers in the park brake position,
disengage deck clutch, remove ignition switch key and disconnect
negative battery cable before doing any adjustments.
2. Place the control lever in the neutral position. Fig. 9-25
3. Loosen the steering dampener’s rear ball stud.
4. Pull the dampener spring housing, to the rear, past the point that the
internal spring is engaged.
5. Release the dampener spring housing and allow the internal spring to
bring the housing back to the neutral position.
6. Tighten the nut on the steering dampener’s rear ball stud.
7. To check, move the control lever to the reverse position and release.
The control lever should return to the neutral position. If not, repeat
steps 1 thru 6.

Park brake spring adjustment
Occasionally check the park brake spring adjustment using the following
method:
1. Shut engine off, place control levers in the park brake position,
disengage deck clutch, remove ignition switch key and disconnect
negative battery cable before doing any adjustments.
2. Position the control lever in the neutral position.
3. Make sure the brake actuator lever and the brake link are all the way
down. Fig. 9-28
4. Tighten the nylock nut on top of the spring assembly until it is
touching the top flat washer. Do not compress the spring. Fig. 9-29
5. Place the control lever in the park brake position. The brake pawl
should now be activated and engaging the integrated pump/motor
brake gear. Fig. 9-30
6. Repeat steps 2 thru 4 for the other side.
Park brake switch adjustment
Occasionally the park brake switch may need adjustment. Use the
following method to adjust the switch:
1. Park the unit on a flat surface. Stop the engine and remove the
ignition key. Place control levers in the park brake position.
2. Loosen the screws holding the switch. Fig. 9-28
3. Slide the switch all the way down until it is fully activated (button
pushed in) against the brake actuator lever.
4. Tighten the screws.
Hydraulic pump belt adjustment
The pump drive belt tension remains constant by means of a tension idler
and spring (Fig. 9-31). There is no tension adjustment of this belt. NOTE:
Inspect the belt every 100 hours and replace as needed. Replace the
belt every 200 hours or every two (2) years whichever comes first.
WARNING: If the pump belt fails, loss of control will occur
especially when operating on a slope. If you lose steering
control while operating the machine, place the steering
control levers in the park brake position immediately.
Inspect the machine and involve your Hustler dealer to
resolve the problem before continuing to operate.
Deck drive belt adjustment
The spindle belt tension remains constant by means of a tension idler and
spring (Fig. 9-32). The spring tension should be such that the belt does not
slip under normal operating load conditions, assuming the belt is not
excessively worn or damaged. As belt stretches and wears in, adjustment
may become necessary. To increase belt tension, move the spring chain
one (or more) link(s) at the anchor bracket (Fig. 9-32). Installed spring
length should be 7.50" ± .3" (19.05 cm ± .76 cm) originally with
adjustments of .60" (15.2mm) per chain link. (Fig. 9-32 & 9-33)
IMPORTANT: Do not over tension the spring to compensate for a
badly worn belt or pulley.
Engine RPM setting
The FasTrak 44/52 is designed so that the engine will run at 3400 rpm
with integrated pump/motor load only. At this speed the integrated
pump/motors are running at their maximum rated speed.

Deck leveling and height adjustment
The mower deck has three areas that may need to be checked and
adjusted periodically. Before considering any mower deck leveling
adjustments, check that the tire air pressure is within the specified range.
Deck level adjustments
Leveling the deck must be done in the following manner and order:
1. Check tire pressures to make certain they are properly inflated before
starting to level deck. The recommended pressures are as follows:
WARNING: Stop engine. Make sure deck clutch switch is in
the down (OFF) position. Remove ignition key. Place control
levers in the brake position before leaving machine.
2. Park the unit on a flat surface.
3. Raise deck and place 3" of blocking under all 4 corners of the deck
(Fig. 9-34). This will set the cutting height at 3 ¼ ". NOTE: Back
of deck will automatically be set ¼" higher.
4. Set cutting height at 3 ¼" in the height indicator by placing the
height adjusting stop in the 3" hole, and turning the height stop so
that the flat side is against the stop handle. Fig. 9-35
5. Clamp the height adjusting stop against the stop handle (Fig. 9-35).
This will assure that the height will not move during the setting
process. Otherwise, spring pressure from the deck lift springs will
tend to pull the stop away from the handle.
6. Loosen all nuts on the deck lift threaded rods, and the hardware on
the adjuster (on the right front), until all the deck lift chains are
loose, and the deck is sitting tightly on all four blocks. Fig. 9-36, 937, 9-38
7. Loosen the two nuts on the front of height indicator so that the foot
pedal is free. Fig. 9-39
8. Start the leveling process on the left front of the tractor.
9. Set the amount of threads protruding on the deck lift rod from the lift
block at approximately 1". Fig. 9-40
10. Jam both nuts against the block.
11. Push or pull on the deck lift foot pedal until the chain on the left
front just becomes tight, making sure that the deck stays tight
against the 3" block.
12. While keeping the chain tight, tighten the nuts against the deck lift
block on the height indicator rod. Fig. 9-39
13. Go to the right front of the tractor.
14. Loosen the 5/16" jam nut on the adjuster lift chain (Fig. 9-38), and
back the adjuster bolt out to allow the adjuster to move up and down
freely.
15. Be sure that adjuster is free to move up and down.
16. Tighten the adjuster bolt until the chain just becomes tight, making
sure that the deck stays tight against the 3" block.
17. Tighten the adjuster bolt jam nut to prevent the adjuster bolt from
moving. Fig. 9-38
18. Tighten the hardware holding the chain and adjuster onto the deck
lift arm.
19. Go to the right rear of the tractor.
20. Make sure that there is still slack in the chain. If not, loosen the two
nuts on the block holding the threaded rod until there is slack in the
deck lift chain. Fig. 9-38
21. Tighten the appropriate nut until the chain just becomes tight,
making sure that the deck stays tight against the 3" block.
22. Tighten the other nut on the opposite side of the block, and jam them
tightly together against the block.
23. Go to the left rear of the tractor.
24. Make sure that there is still slack in the chain. If not, loosen the two
nuts on the block holding the threaded rod until there is slack in the
deck lift chain. Fig. 9-36
25. Tighten the appropriate nut until the chain just becomes tight.
26. Tighten the other nut on the opposite side of the block, and jam them
tightly together against the block.
27.
Compress the deck lift assist springs so that there is 1” of space
between the front nut on the spring and the rear nut on the deck lift
block (Fig. 9-40). Typical both sides.
28. When completed, all chains will be tight, and deck cutting height
will be set to the deck height indicator.
