this system; use only motor oil as specified. Remember, dirt is the primary
enemy of any hydraulic system.
WARNING: Hydraulic oil escaping under pressure can
penetrate skin. Hydraulic oil may cause infection in a minor
cut or opening in the skin. If exposed to hydraulic fluid, see
a doctor at once.
Before applying pressure to hydraulic system, make sure all
connections are tight and all hoses and lines are in good
condition. To find a leak under pressure, use a piece of
cardboard or wood — never use your hands. Relieve all
pressure in the system before disconnecting or working on
hydraulic lines. To relieve pressure, lower all attachments
and shut off engine.
Check oil level in hydraulic system after every 50 hours of operation or
weekly, whichever occurs first. Check more often if system appears to be
leaking or otherwise malfunctioning.
Fluid level should be 1” (2.54 CM ) from top of reservoir. Use only SAE
10W40 SG, SF/CC, CD service motor oil.
Change hydraulic system filter element after first 50 hours of tractor
operation, then replace filter and oil in reservoir every 500 hours thereafter.

air pressure. The recommended pressure are:
Drive wheels...............................................8-12 psi (55-83 KPa )
Gauge wheels .............................................8-12 psi (55-83 KPa )
Solid fill tires are not recommended for Hustler turf equipment. On
any machine, with solid filled tires, the warranty claim will be denied.
Lubrication
Use SAE multi-purpose grease.
Electrical system
The electrical system is a 12 volt, negative ground. Recommended
battery size is a garden tractor BCI group U1R with 225 or better cranking
AMP rating. A maintenance-free battery is recommended. Otherwise,
follow battery manufacturer’s maintenance, safety, storing and charging
specifications.
Hustler Z Shibaura diesel units only - These models require a
recommended battery size BCI group 45 with 480 or better cranking AMP
rating.
WARNING: Battery posts, terminals, and related
accessories contain lead and lead compounds, chemicals
known to cause cancer and reproductive harm. Wash hands
after handling.
WARNING: Charge batteries in an open well ventilated
area, away from sparks and flames. Unplug charger before
connecting or disconnecting from battery. Wear protective
clothing and use insulated tools.
WARNING: Avoid skin contact with battery acid.
Always wear eye protection when checking the battery, acid
can cause serious injury to skin and eyes. If contact occurs,
flush area with clean water and call physician immediately.
Acid will also damage clothing.
Do not allow open flame near the battery when charging.
Hydrogen gas forms inside the battery. This gas is both toxic
and flammable and may cause an explosion if exposed to
flame. Always remove the negative ground first and replace
it last.
Do not overfill battery.
Electrolyte may overflow and damage paint, wiring or
structure. When cleaning the battery, use soap and water. Be
careful not to get soap and water into the battery. Use soda
mixed in water to clean corrosion off the terminals.
WARNING: Shorts caused by battery terminals or metal
tools touching metal tractor components can cause sparks.
Sparks can cause a battery gas explosion which will result in
personal injury.
Prevent the battery terminals from touching any metal tractor
parts when removing or installing the battery.
Do not allow metal tools to short between the battery
terminals and metal tractor parts.
WARNING: Incorrect battery cable routing could cause
damage to the tractor and battery cables. This can cause
sparks which can cause a battery gas explosion which will
result in personal injury.
Always disconnect the negative (black) battery cable(s)
before disconnecting the positive (red) cable(s).
Always connect the positive (red) battery cable(s) before
connecting the negative (black) cable(s).
NOTE: The Hustler Z Shibaura Diesel tractors have a 50 amp in-
line fuse in the electrical system. This is the main fuse to protect the
complete electrical system. It is located at the rear of the machine close to
the battery. Fig. 4-1
