Hydraulic System
Maintenance
Changing the Hydraulic
Fluid
Change the hydraulic fluid after every 800
operating hours, in normal conditions. 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. Loosen the drain valve on the bottom of the
reservoir and let the hydraulic fluid flow into
large drain pan. Close the valve when the
hydraulic fluid stops draining.
3. Fill the reservoir (Figure 69) with approximately
8 U.S. gallons (30 l) of hydraulic fluid; refer to
Checking the Hydraulic Fluid.
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
hydraulic fluid throughout the system. Also
check for leaks; then stop the engine.
5. Check the fluid level and add enough to raise
level the level to the Full mark on the dipstick.
Do not overfill.
Replacing the Hydraulic
Filters
Change the 2 hydraulic filters initially after the
first 200 operating hours. Thereafter, change the
filters after every 800 operating hours, in normal
conditions.
Use Toro replacement filters (Part No. 94-2621
for the left side of the machine and 75-1310 for
the right side of the machine).
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 brakes, and remove the ignition key.
2. Clean the area around the filter mounting area.
Place a drain pan under the filter and remove
the filter (Figure 71).
