A maintenance-free battery is recommended. Otherwise,
follow battery manufacturer’s maintenance, safety, storing
and charging specifications.
System Fuses
The electrical system for this mower includes three fuses:
A. Master in-line fuse (30 amp) – Main fuse to protect the
complete electrical system. It is located at the right
rear of the engine next to the solenoid. Figure 4-1
B. Deck clutch fuse (15 amp) – This fuse protects the deck
clutch. It is located under the right front of the control
panel. Figure 4-2
C. Ignition/Safety system fuse (10 amp) – This fuse
protects the ignition and safety circuit components. It
is located under the right front of the control panel.

Hydraulic System
IMPORTANT: Never use hydraulic or automatic transmis-
sion fluid in this system; use only synthetic motor oil as
specified. Remember, dirt is the primary enemy of any
hydraulic system.
Check oil level in hydraulic system after every 50 hours of
operation or weekly, whichever occurs first. The hydraulic
system must be cool when checking the oil level and the
mower should be on level ground. Check more often if
system appears to be leaking or otherwise malfunctioning.
Use the hydraulic reservoir’s sight glass to check the
reservoir fluid level. The oil level should be approximately in
the middle of the sight glass. Figure 4-3
Use 15W50 or 20W50 synthetic oil when changing the
system oil and filter. For maximum transmission life, use
Hustler
®
100% Synthetic 20W50 Hydrostatic Transmission
Oil.
NOTE: The reservoir (Figure 4-4) will require approximately
1.0 U.S. gallons (3.78 liters) of full synthetic 15W50 or 20W50
oil when replacing the oil after an oil and filter change. Do not
overfill the reservoir.
Initial system oil and filter change must be after the first 50
hours of mower operation. Thereafter, replace filter and oil in
the reservoir annually or every 500 hours, whichever comes
first.
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
adding system oil.
The system filter is located at the left rear of the engine.
Use a Hustler
®
approved filter element only. When changing
the filter use a standard oil filter wrench. The threads are
right hand. Figure 4-5
IMPORTANT: Pre-fill the filter element with clean oil
before installing, to prevent drawing air into the system
pump.
Refer to the Hustler
®
Super S
®
General Service Manual (P/N
123944) for complete hydraulic oil and filter change
procedures.

Hydraulic fluid escaping under pressure may have
sufficient force to penetrate skin and cause
serious injury. Foreign 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 working on
hydraulic lines. To relieve pressure, lower all
attachments and shut off engine.
