MAINTENANCE & ADJUSTMENTS
Safe Servicing Practices
Refer to the Safety Precautions section of this manual for
more 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 for more
information.
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 hydraulic component areas; minute dust
particles 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,
restricting blade and air movement which will probably result
in 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 off 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
Torque values are given below:
ft-lbs N•m
Wheel (lug) nuts . . . . . . . . . . . . . . . . .70 . . . . . . . . . 95
Blade spindle bolt top. . . . . . . . . . . . 118 . . . . . . . 160
Blade spindle bolt bottom . . . . . . . . 118 . . . . . . . 160
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 Product Literature
section for ordering information.
For engine torque values, refer to the 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:
Drive wheels . . . . . . . . . . . . . . . . . . 8–12 psi (55–83 KPa)
Front wheels . . . . . . . . . . . . . . . . . . 8–12 psi (55–83 KPa)
If you wish to use non-pneumatic tires on your Hustler
®
mower, the tire must be a Hustler
®
approved tire. Warranty
claims will be denied on any mower equipped with
unapproved non-pneumatic tires.
Lubrication
Use no more than 1 or 2 ounces (30–60 cc) of SAE multi-
purpose grease, (1 to 2 pumps on an average grease gun). Do
not force lubricant in to grease zerks. Bearings are sealed
and do not require much lubricant.
After every 50 hours of normal operation, apply a SAE
multi-purpose grease to the other lubrication points shown
on the Maintenance Locator Chart found elsewhere in this
manual. When operating under extremely dirty conditions,
lubricate more frequently than every 50 hours.
To lubricate these points:
1. Wipe away all old grease and dirt from the lubrication
fittings to prevent dirt or foreign material from
entering as new grease is applied.
2. Use a high pressure grease gun to force in the new
grease. Apply pressure until clean grease oozes from
each lubrication point.
3. Wipe away any excess grease.
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.
