Hydraulic System - HUSTLER Diesel Z Operator's Manual

WARNING
Shorts caused by battery terminals or metal tools touch-
ing metal mower components can cause sparks. Sparks
can cause a battery gas explosion which will result in per-
sonal injury.
• Prevent the battery terminals from touching any
metal mower parts when removing or installing the
battery.
• Do not allow metal tools to short between the bat-
tery terminals and metal mower parts.
WARNING
Incorrect battery cable routing could cause damage to the
mower and battery cables. This can cause sparks which
can cause a battery gas explosion which will result in per-
sonal 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).
Master in-line fuse
The Hustler Diesel Z mowers 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. Figure 4-1

Hydraulic System

IMPORTANT: Never use hydraulic or automatic transmis-
sion fluid in this system; use only motor oil as specified.
Remember, dirt is the primary enemy of any hydraulic system.
WARNING
Hydraulic fluid escaping under pressure may have suffi-
cient force to penetrate skin and cause serious injury. For-
eign fluid injected into the skin must be surgically
removed within a few hours by a doctor, familiar with this
form of injury, or gangrene may result.
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 work-
ing 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" (25.4mm) from top of reservoir. Use
only SAE 20W50 SL/SM service motor oil. Figure 4-2
NOTE: The reservoir will require approximately 7 U.S.
quarts (6.6 liter) of SAE 20W50 SL/SM service motor oil when
replacing the oil after an oil and filter change. Do not overfill
the reservoir.
Change hydraulic system filter element and oil after first 50
hours of machine operation, then replace filter and oil in
reservoir every 500 hours thereafter. Figure 4-3
IMPORTANT: It is necessary to drain the system oil from
the hydraulic reservoir, using the reservoir drain plug, before
removing the hydraulic filter. Replace the drain plug before add-
ing system oil.
The Hustler Diesel Z system filter is located inside the
®
hydraulic reservoir on the rear underneath side of the tank. Use a
