The mower ships from the factory with SAE 20W50 motor oil
in the system. Use SAE 20W50 motor oil, 15W50 synthetic oil or
20W50 synthetic oil when changing the system oil and filter.
For maximum transmission life use Hustler
20W50 Hydrostatic Transmission Oil.
When the hydraulic system oil is cold, the fluid level should
be at the "Full Cold" line on the expansion tank.
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 the filter. Figure 4-3
Each transmission's filter is located per Figure 4-3. A
standard oil filter wrench is used to change the filter. The
threads are right handed. Use a Hustler
element only.
IMPORTANT: When washing the mower, direct the spray
away (especially if using a power washer) from the
transmission's seals to prevent water intrusion and to ensure
component performance.
