HYDRAULIC MAINTENANCE
CAUTION
Before servicing or making adjustments to the
machine, stop engine and remove key from
the switch.
CHANGING HYDRAULIC FLUID (Fig. 69 - 71)
Change hydraulic fluid after every 400 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. Turn engine off and raise hood.
2. Disconnect hydraulic line or remove hydraulic filter
and let hydraulic fluid flow into drain pan. Reinstall line
when hydraulic fluid stops draining.

3. Fill reservoir with approximately 3.5 gallons of
hydraulic fluid. Refer to Checking Hydraulic Fluid.

IMPORTANT: Use only hydraulic fluids specified.
Other fluids could cause system damage.
4. Install reservoir cap. Start engine and use all
hydraulic controls to distribute hydraulic fluid
throughout the system. Also check for leaks. Then stop
the engine.
5. Check level of fluid and add enough to raise level to
FULL mark on dipstick. DO NOT OVER FILL.
REPLACING HYDRAULIC FILTER (Fig. 70)
The hydraulic system filter must be changed initially,
after the first 10 hours of operation, and thereafter
every 200 hours of operation or yearly, whichever
comes first. Use a genuine Toro oil filter for
replacement. The hydraulic oil must be changed every
400 hours of operation or yearly, whichever comes first.
Use the Toro replacement filter (Part No. 54-0110).
IMPORTANT: Use of any other filter may void the
warranty on some components.
1. Position machine on a level surface, lower the
cutting units, stop the engine, engage the parking
brake and remove key from ignition switch.
2. Pinch off hose to filter mounting plate.
3. Clean area around filter mounting area. Place drain
pan under filter and remove filter.
4. Lubricate new filter gasket and fill the filter with
hydraulic fluid.
5. Assure filter mounting area is clean. Screw filter on
until gasket contacts mounting plate. Then tighten filter
one-half turn.
6. Start engine and let run for about two minutes to
purge air from the system. Stop the engine and check
for leaks.
CHECKING HYDRAULIC LINES AND
HOSES
Daily, check hydraulic lines and hoses for leaks, kinked
lines, loose mounting supports, wear, loose fittings,
weather deterioration and chemical deterioration.
Make all necessary repairs before operating.
