Changing the Hydraulic
Fluid and Filters
Service Interval: After the first 1000 hours—Change
the hydraulic fluid and hydraulic
filter.
Every 1,000 hours—Change the hydraulic filter.
Every 2,000 hours—Change the hydraulic fluid.
If the hydraulic fluid becomes contaminated, contact
your authorized Toro distributor; the system must be
flushed. Contaminated fluid looks milky or black when
compared to clean fluid.
Important:
Use Toro replacement filters; refer to
the machine Parts Catalog . Using any other filter
may void the warranty on some components.

2. Place a large drain pan under the hydraulic-fluid
tank.
3. Remove the hydraulic-tank cap and dipstick.
4. Remove the drain plug ( Figure 74 ) from the

A. Use the traction pedal to move the machine
forward and backward.
B. Use the steering wheel to move the tires all
the way to the right and left.
C. Use the lift switch to raise and lower the
attachment (e.g., cutting unit).
13. Check for leaks and shut off the engine.
