Warning
Before servicing or making adjustments to the
machine, stop the engine and remove the key from
the switch. Lower the cutting units to the ground.

Changing the Hydraulic Fluid

Change hydraulic fluid after every 800 operating hours, in
normal conditions. If fluid becomes contaminated, contact
your local TORO distributor because the system must be
flushed. Contaminated fluid looks milky or black when
compared to clean oil.
1. Turn engine off and set parking brake.
2. Remove drain plug from bottom of reservoir and let
hydraulic fluid flow into drain pan. Reinstall and
tighten plug when hydraulic fluid stops draining.

3. Fill reservoir with approximately 8–1/2 gallons of
hydraulic fluid. Refer to Checking Hydraulic Fluid,
page 21.
Important
Use only hydraulic fluids specified. Other
fluids could cause system damage.
4. Install reservoir cap. Start engine and use all hydraulic
controls to distribute hydraulic fluid throughout the
system. Also check for leaks. Then stop the engine.
5. Check level of fluid and add enough to raise level to
full mark on dipstick. Do Not Over Fill.

Replacing the Hydraulic Filter

The hydraulic system filter head is equipped with a service
interval indicator. With the engine running, view the
indicator, it should be in the green zone. When the
indicator is in the red zone, the filter element should be
changed.
Use the Toro replacement filter (Part No. 94-2621).
Important Use of any other filter may void the
warranty on some components.
1. Position machine on a level surface, lower the cutting
units, stop the engine, engage the parking brakes and
remove key from ignition switch.
2. Clean area around filter mounting area. Place drain pan
under filter and remove filter.
