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

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 . . . . . . . . . . . 15-20 psi (103-138 KPa)
Front wheels . . . . . . . . . . . 20-25 psi (138-172 KPa)

BCI group 45 with 480 or better cranking AMP rating.
A maintenance-free battery is recommended. Otherwise,
follow battery manufacturer's maintenance, safety, storing and
charging specifications.
WARNING
Battery posts, terminals, and related accessories contain
lead and lead compounds, chemicals known to the State
of California to cause cancer and reproductive harm.
