Master In-Line Fuse
These mowers have a master in-line fuse in the electrical
system. This is the main fuse to protect the complete electri-
cal system. It is located under the seat platform and next to
the solenoid. Figure 4-1
Hydraulic System
This mower is equipped with two integrated hydrostatic
transmissions. Figure 4-2
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 sys-
tem.
The hydraulic expansion tank is located in front of the
engine and under the operator’s platform. Figure 4-2
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 malfunc-
tioning.
Fluid level should be at the “Full Cold” line on the expan-
sion tank. Use only SAE 20W50 service motor oil.
Initial system oil and filter change must be after the first 75
hours of use or 1 year whichever comes first. Thereafter,
replace filter and oil in each transmission every 2 years or
200 hours, whichever comes first. NOTE: The filter guard
must be removed to access filter.
Each transmission’s filter is located per Figure 4-3. A stan-
dard oil filter wrench is used to change filter, threads are
right handed. Use a Hustler
®
approved filter element only.
