Important
Use only the hydraulic fluids specified.
Other fluids could cause system damage.

4. Install the reservoir cap. Start the engine and use all of
the hydraulic controls to distribute the hydraulic fluid
throughout the system. Also check for leaks; then stop
the engine.
5. Check the fluid level and add enough to raise the level
to FULL mark on the dipstick. Do not overfill.
Replacing the Hydraulic Filter
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 Toro replacement filter Part No. 86-3010.
Important
Use of any other filter may void the
warranty on some components.
1. Position the machine on a level surface, lower the
cutting units, stop the engine, engage the parking brake,
and remove the key from the ignition switch.
2. Pinch off the hose to the filter mounting plate.
3. Clean around the filter mounting area. Place a drain pan
under the filter (Fig. 49) and remove the filter.
4. Lubricate the new filter gasket and fill the filter with
hydraulic fluid.
5. Ensure that the filter mounting area is clean. Screw the
filter on until the gasket contacts the mounting plate;
then tighten the filter 1/2 turn.
6. Start the engine and let it run for about two minutes to
purge air from the system. Stop the engine and check
for leaks.
Checking the 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.
Warning
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Make sure all hydraulic fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
• Keep your 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.
• Seek immediate medical attention if fluid is
injected into skin.
Adjusting the Traction Drive for
Neutral
If the machine moves when the traction pedal is in the
neutral position, the traction cam must be adjusted.
1. Park the machine on a level surface and turn the engine
off.
2. Raise one front wheel and one rear wheel off of the
floor and place support blocks under the frame.
Warning
If the machine is not supported adequately, it may
accidentally fall, injuring anyone under the
machine.
One front wheel and one rear wheel must be raised
off of the ground or the machine will move during
adjustment.
