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 prob-
lem. 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 build-
up of grass clippings and dirt, especially when grass is wet or
has high moisture content. This build-up will harden, restrict-
ing 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 person-
nel. Consult your Hustler
®
service center when assistance is
needed.
Torque Values
Torque values are given below:
ft-lbs
N•m
Wheel (lug) nuts . . . . . . . . . . . . . . . . . 70 . . . . . . . . . 95
Blade spindle bolt top. . . . . . . . . . . . . 73 . . . . . . . . . 99

Lug nuts only -
It is recommended that these be checked
after the first 2 hours of operation, initially, every 50 hours
and following removal for repair or replacement.
For all other torques refer to the mower’s
General Service
Manual
for standard torque chart. See the
Product Literature
section for ordering information.
For engine torque values, refer to the engine owner’s man-
ual.
Tires
It is important for level mowing that the tires have the
same amount of air pressure. The recommended pressures
are:
Drive wheels . . . . . . . . . . . . . . . . . . 8–12 psi (55–83 KPa)
Front wheels . . . . . . . . . . . . . . . . . . 8–12 psi (55–83 KPa)
Only pneumatic tires are approved for use on this mower.
Warranty claims will be denied on any mower equipped with
non-pneumatic tires.
Lubrication
Use SAE multi-purpose grease.
Electrical System
IMPORTANT: Refer to the
Safety
section of this manual for
detailed battery servicing safety information.
The electrical system is a 12 volt, negative ground. The rec-
ommended battery size is:
Garden tractor BCI group U1R with a 225 or better
cranking AMP rating
A maintenance-free battery is recommended. Otherwise,
follow battery manufacturer’s maintenance, safety, storing
and charging specifications.
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.
