Maintenance
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. Shut off the engine and raise the hood.
2. Place a large drain pan under the fitting secured to the
bottom of the hydraulic-fluid reservoir

3. Disconnect the hose from the bottom of the fitting and
let the hydraulic fluid flow into the drain pan.
4. Install the hose when hydraulic fluid stops draining.
5. Fill the reservoir with approximately 56.7 L (15 US
gallons) of hydraulic fluid; refer to
Hydraulic Fluid (page
Important: Use only hydraulic fluids specified.
Other fluids could cause system damage.
6. Install the reservoir cap.
7. Start the engine and use all of the hydraulic controls to
distribute hydraulic fluid throughout the system. Also
