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.

WARNING: Keep your machine clean, remove any deposits of trash and clippings, which can cause engine fires and hydraulic overheating as well as excessive belt wear.

Clear away heavy build-up of grease, oil and dirt, especially in the engine and hydraulic reservoir area; minute dust particles are abrasive to close-tolerance engine and hydraulic assemblies.

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

Particular attention must be given to tightening the drive wheel lug and wheel motor nuts. Failure to correctly torque these items may result in the loss of a wheel, which can cause serious damage. Torque values given below are in foot

pounds.
Wheel (lug) nuts	.............................65-75 ft.-lbs.
Wheel motor nut	.........................425-450 ft.-lbs.

It is recommended that these be checked after the first 2 hours of operation, initially and every 50 hours following removal for repair or replacement.

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	14-18 psi
Tail Wheels	14-18 psi

If the machine has Hustler Range Wings or a Hi-Lift BAC-VAC then the tire pressure should be increased to:

Drive Wheels	20-22 psi
Tail Wheels	20-22 psi

Solid fill tires are not recommended for Hustler turf equipment. On any machine, with a failure due to solid filled tires, the warranty claim will be denied.

Hour meter

To recognize when your machine needs servicing, check the hour meter and the maintenance schedule. The hour meter shows the number of hours the engine has run and the maintenance schedule lists the service intervals.

Lubrication

There are seven grease fittings on the tractor which require regular servicing. Use a good grade SAE multi- purpose grease and wipe accumulated dirt from fitting

before attaching grease gun. Refer to the diagram for location and frequency.

Steering linkage

There are two types of steering adjustments that are discussed in this section.

1.Neutral adjustment in the neutral lock position.

2.The rotational resistance spring and linkage connecting the two pump levers, located near the pump.

Prior to making either of these adjustments, visually inspect the urethane grommets at the hydraulic pump end of the steering control levers (or linkage straps) and ball joints at front at least once a month or every 200 hours of operation, whichever occurs first. These grommets and ball joints must be replaced if lost or worn.

WARNING: Failure to maintain these grommets and ball joints will affect steering.

Visually inspect steering shock absorbers every 500 hours for damage or wearing. If excessive oil leakage is evident, then replace that shock absorber.

The tractor steering has been factory adjusted to eliminate creeping when the neutral lock is engaged. However, should the tractor begin to creep, the steering control lever linkage can be adjusted as follows (Fig. 5-1 and 5-2):
