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.
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 hydraulic reservoir areas;
minute dust particles 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 in the full up position, using jack stands or blocks,
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, wheel motor 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.
Torque values are given below:
Ft-lbs. Nm
Wheel (lug) nuts................................. 65-75...........88.14-101.7
Wheel motor nut...............................290-310.........393.2-420.4
Blade spindle bolt top.........................65-75...........88.14-101.7
Blade spindle bolt bottom.....................118.................160.01
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 various tractor parts manuals for standard torque charts.
NOTE: 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:
Drive wheels........................... 8-12 psi (55-69 KPa)
Gauge wheels ............................semi-pneumatic
The bar tread tires are reversed from what is considered the normal operating position. this allows for bet-
ter traction when backing up a slope.
