Hydraulic System
IMPORTANT: Refer to the General Service Manual (P/N
123499) for complete hydraulic oil and filter change proce-
dures.
IMPORTANT: Never use hydraulic or automatic transmis-
sion fluid in this system; use only specified oil. 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. Check more often if system
appears to be leaking or otherwise malfunctioning.
When checking the hydraulic system’s oil level:
1. Always check oil level with the mower on level ground.
2. Always check oil level when the oil is cold (mower has
not run for at least 1.5 hours).
3. Always check oil level with the dipstick installed and
tightened.
IMPORTANT: Full level when oil is cold is anywhere on
the dipstick, up to the “H” line. Oil must not be above
the "H" (High mark). Figure 4-2
Change hydraulic system filter element and oil after first
750 hours of mower operation, then replace filter and oil in
reservoir every 500 hours thereafter.
The following is a list of the oils that are approved for use
in the Hustler
