Hydraulic System
Change Hydraulic Oil
Normally, change hydraulic oil after every 2 years or
1500 operating hours. If oil becomes contaminated,
contact your local TORO distributor because the system
must be flushed. Contaminated oil looks milky or black
when compared to clean oil.
1. Remove drain plug from reservoir and let hydraulic
oil flow into drain pan. Tighten plug when hydraulic oil
stops draining (Fig. 91).
2. Fill reservoir with approximately 9.3 gallons of hy-
draulic oil. Refer to Hydraulic Oil Specifications.
IMPORTANT: Use only hydraulic oils specified.
Other fluids could cause system damage.
3. Install reservoir cover, lower seat and secure with
lock pin. Start engine and use all hydraulic controls to
distribute hydraulic oil throughout the system. Also
check for leaks. Then stop the engine.
4. With cutting units up and oil warm, look into sight
glass. If hydraulic oil is not even with arrows, add
enough to raise to proper level. Do not fill full if oil is cold
(Fig. 92).
