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-fluid leaks.
• Safely relieve all pressure in the
hydraulic system before performing
any work on the hydraulic system.
• Make sure that all hydraulic hoses and
lines are in good condition and that all
hydraulic connections and fittings are
tight before applying pressure to the
hydraulic system.

Replacing the Hydraulic Filters
and Hydraulic Fluid
Service Interval: After the first 250 hours—Change
the hydraulic filters and hydraulic
fluid when using any type of fluid.
Every 250 hours—Change the hydraulic filters
and hydraulic fluid when using Mobil
(more often in dirty or dusty conditions).
Every 500 hours—Change the hydraulic
filters and hydraulic fluid when using Toro
HYPR-OIL ™ 500 hydraulic fluid (more often in
dirty or dusty conditions).
To replace the hydraulic fluid, you must remove the
filters. Replace both filters at the same time; refer to
Servicing the Hydraulic System (page 55)
specifications.
1. Disengage the blade-control switch (PTO), move
the motion-control levers to the N

2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3. Raise the machine and support it with jack
stands (Figure

4. Remove both the mower belt and the pump-drive
belt; refer to Replacing the Mower Belt (page
51) and Replacing the Hydraulic Pump-Drive
Belt (page 52).
