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. Cor-
recting 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 person-
nel. Consult your Hustler service center when assistance is needed.
General engine maintenance
Detailed instructions and recommendations for break-in and regular maintenance are specified in the Engine
Owner’s manual. Please refer to this manual for engine servicing, lubricating oil levels with quality and viscosity recom-
mendations, bolt torques, etc. The engine warranty is backed by the manufacturer. Special attention should be paid to
applicable data which will not be duplicated here.
Torque values
WARNING: Particular attention must be given to tightening the drive wheel lug nuts, wheel motor
