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” from top of reservoir. Use only SAE 20W50 SG, SF/CC, CD service motor oil.
Change hydraulic system filter element ("FIG. 34") after first 50 hours of tractor operation, then replace
filter and oil in reservoir every 500 hours thereafter.
The system filter is located directly in front of the hydraulic reservoir. A standard oil filter wrench is used to
change filter, threads are right handed.
Use a Hustler approved filter element only.
IMPORTANT: Prefill the filter element with clean oil, before installing, to prevent drawing air into the
system pump.
1. Fill the filter element with clean system oil. Smear a light coating of oil on upper surface of rubber seal.
2. Install the filter element on base. Tighten the oil filter by hand until the filter seal makes contact with the
filter head, then tighten an additional 3/4 - 1 turn with an oil filter wrench. — DO NOT OVERTIGHTEN.
3. Start tractor engine and let run at approximately 2/3 throttle for a few minutes to work any trapped air out of
the system before engaging the steering control lever.
4. Stop the engine and check the filter and connections for leaks.
5. Check the hydraulic reservoir for specified oil level. Add clean oil as necessary.
Clean or replace hydraulic reservoir cap annually. Cap may be cleaned by dipping in or flushing with
cleaning solvent. Follow manufacturer’s instructions and warnings for application of solvent type selected.
