Torque Values; Tires; Lubrication; Electrical System - HUSTLER ATZ Operator's Manual

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, 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
using jack stands or blocks in the full up position. 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.

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, 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 (55-83 KPa)
Gauge wheels (if applicable). . . . . . . . . 8-12 psi (55-83 KPa)
IMPORTANT: Drive tire tread orientation is important on
the Hustler ® ATZ. Tire tread direction must be as shown in Fig-
ure 4-1. This is the opposite of normal installation for this type
of tire.
IMPORTANT: Non-pneumatic tires are not approved for
