Safe Servicing Practices
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 ser-
vicing or making adjustments to tractor. Park the machine on level
ground. Place steering control levers in the park brake position, disen-
gage deck clutch, lower deck, remove ignition switch key and discon-
nect 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.
▲ Before working on or under the deck, make certain engine cannot be
accidentally started. Shut engine off and remove ignition switch key
for maximum safety. Repairs or maintenance requiring engine power
should be performed by trained 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.
▲ Keep your machine clean and remove any deposits of trash and clip-
pings, 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 keep-
ing the top of the deck, engine compartment, exhaust area, bat-
tery, 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.
▲ Always wear adequate eye protection when servicing the hydraulic
system and battery, or when grinding mower blades and removing
accumulated debris.
▲ Use extra caution when handling gasoline and other fuels. They are
flammable and vapors are explosive.
▲ Never attempt to start engine when there is a strong odor of gasoline
fumes present. Locate and correct cause.
▲ Never remove 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.
▲ 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 run-
ning 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 sup-
ported 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.
▲ Never tamper with safety devices. Check their proper operation regu-
larly.
▲ Stop the engine before removing the grass catcher or unclogging the
discharge chute. Never clear the discharge chute with the engine run-
ning. 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 manufac-
turer’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.
▲ Use only genuine Hustler replacement parts to ensure that original
standards are maintained
Introduction
Regular maintenance is the best prevention for costly downtime or expen-
sive, 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 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 ser-
vice. 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 under-
neath.
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.
