8. Remove plastic bag from reservoir opening
and allow filter to fill with hydraulic fluid.
9. When the hydraulic filter is full, turn the oil
filter clockwise until the rubber gasket contacts
the filter adapter, then tighten the filter an
additional 1/2 turn (Figure 67).

10. Clean up any spilled fluid.
11. If there is no fluid or it is low, 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.
12. 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.
13. Recheck level and add fluid, if required. Do
not overfill.
Bleeding the Hydraulic System
The traction system is self bleeding, however, it
may be necessary to bleed the system if fluid is
changed or after work is performed on the 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. Raise the rear of the machine up onto jack
stands high enough to raise the drive wheels
off the ground.
4. Start the engine and move the throttle control
to idle position. Move the speed control lever
to the middle speed position and place one
drive lever into the drive position.
If the drive wheel does not rotate, it is possible
to assist the purging of the system by carefully
rotating the tire in the forward direction.
5. Check the hydraulic fluid level as it drops add
fluid as required to maintain the proper level.
6. Repeat this procedure for the opposite wheel.
7. Thoroughly clean the area around each of the
charge pump housings.
Checking the Hydraulic Lines
After every 100 operating hours, check hydraulic
lines and hoses for leaks, loose fittings, kinked
lines, loose mounting supports, wear, weather and
chemical deterioration. Make necessary repairs
before operating.
Note:
Keep areas around hydraulic system clean
from grass and debris build up.
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.
