Hydraulic Fluid Capacity
30 L (8 US gallons); refer to
Hydraulic Fluid Specifications
(page 72)
Changing the Hydraulic Fluid
Service Interval:
Every 2,000 hours—
If you are using
the recommended hydraulic fluid,
change the hydraulic fluid.
Every 800 hours—
If you are not using the
recommended hydraulic fluid or have ever filled
the reservoir with an alternative fluid,
change the
hydraulic fluid.
If the fluid becomes contaminated, contact your Toro
Distributor because the system must be flushed.
Contaminated fluid looks milky or black when compared
