7. Run the machine at low idle for 15 minutes to allow
any air to purge out of the system and warm fluid.
Refer to Starting and Stopping the Engine.
8. Recheck the fluid level while the fluid is warm. If
required, add fluid to the reservoir until it reaches
the hot level of the baffle.
Note: The fluid level should be to the top of the hot
level of the baffle, when the fluid is warm (Figure 72).
9. Install cap on 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 body and hands away from pin hole
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 and
lines are in good condition and all 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
Every 500 hours—Change the
hydraulic filter and hydraulic oil
when using Toro
hydraulic oil.
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.

7. Change the hydraulic filter. Refer to Replacing the
Hydraulic Filter.
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 engine and let run for about two minutes to
purge air from the system. Stop the engine and
check for leaks. If one or both wheels will not drive,
refer to Bleeding Hydraulic System.
12. Check the level of the fluid and add fluid, if required.
Do not overfill.
