8. Check the fluid level while the fluid is warm.
Note:
If required, add fluid to the reservoir until it is
between the hot level and the cold level.
Note:
The fluid level should be below the hot level of
the baffle when the fluid is warm (Figure 73).
9. Install the cap on the filler neck.
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• If hydraulic fluid is injected into the skin,
it must be surgically removed within a few
hours by a doctor familiar with this type
of injury. Gangrene may result if this is
not done.
• Keep your body and hands away from
pinhole leaks or nozzles that eject
high-pressure hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks.
• Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
• Make sure all hydraulic-fluid hoses are in
good condition, and all that the hydraulic
connections and fittings are tight before
applying pressure to hydraulic system.
Replacing the Hydraulic Fluid
Service Interval: Every 250 hours—Change the hydraulic
filter and hydraulic oil when using Mobil
®
1 oil.
Every 500 hours/Yearly (whichever comes
first)—Change the hydraulic filter and hydraulic oil
when using Toro
® HYPR-OIL ™ 500 hydraulic oil.
Note:
Change the hydraulic fluid more frequently in severe
conditions or in a hot operating climate.
WARNING
Hot hydraulic fluid can cause severe burns.
Allow the hydraulic fluid to cool before performing
any maintenance to the hydraulic system.
1. Disengage the PTO and set the parking brake.
2. Stop the engine and wait for all moving parts to stop
before leaving the operating position.
3. Remove hydraulic-reservoir cap.
4. Locate the front hydraulic hose under the hydraulic
tank, and place a drain pan under the tank (Figure 74).
5. Loosen the hose clamp and move it down the hose.
6. Remove the front hydraulic hose, and allow the fluid to
run out of the tank.

8. Connect the hydraulic hose under the tank.
9. Add fluid to the tank until it reaches the cold baffle
of the tank.
Important:
Use oil specified or equivalent. Other
fluids could cause system damage.
10. Install the hydraulic-tank cap.
11. Start the engine and let it run for about 2 minutes to
purge air from the system.
12. Stop the engine and check for leaks.
Note:
If one or both wheels will not drive, refer to
Bleeding the Hydraulic System (page 52).
13. Check the level of the fluid and add fluid, if required.
Note:
Do not overfill.
