Changing the Hydraulic Filter

Service Interval: After the first 10 hours
Every 200 hours/Yearly (whichever comes first)
Use a genuine Toro replacement filter, Part No. 86-3010.
Important: Use of any other filter may void the warranty
on some components.
1. Position the machine on a level surface, lower the
cutting units, stop the engine, engage the parking brake,
and remove the key from the ignition switch.
2. Pinch off the hose to the filter mounting plate.
3. Clean around the filter mounting area. Place a drain
pan under the filter (Figure 64) and remove the filter.

4. Lubricate the new filter gasket and fill the filter with
hydraulic fluid.
5. Ensure that the filter mounting area is clean. Screw the
filter on until the gasket contacts the mounting plate;
then tighten the filter 1/2 turn.
6. Release the hose to the filter mounting plate.
7. Start the engine and let it run for about two minutes to
purge air from the system. Stop the engine and check
for leaks.

Changing the Hydraulic Fluid

Service Interval: Every 400 hours
If the 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 the engine off and raise the hood.
2. Disconnect the hydraulic line (Figure 65) or remove the
hydraulic filter (Figure 64) and let the hydraulic fluid
flow into a drain pan. Install the hydraulic line when
hydraulic fluid stops draining.

3. Fill the reservoir (Figure 66) with approximately 13.2
liters (3.5 U.S. gallons) of hydraulic fluid; refer to
Checking the Hydraulic System.
Important: Use only the hydraulic fluids
specified. Other fluids could cause system
damage.

4. Install the reservoir cap. Start the engine and use all of
the hydraulic controls to distribute the hydraulic fluid
throughout the system. Also check for leaks; then stop
the engine.
5. Check the fluid level and add enough to raise the level
to Full mark on the dipstick. Do not overfill.
