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. Raise rear of the machine so wheels are off the
ground and support with jack stands.
2. Start the engine and run at low idle speed. Engage
the lever and traction on one side and spin the wheel
by hand.
3. When the wheel begins to spin on its own, keep it
engaged until wheel drives smoothly. (minimum
2 minutes)
4. Check the hydraulic fluid level and add as required
to maintain proper level.
5. Repeat this procedure on the opposite wheel.
Checking the Hydraulic Hoses
Service Interval: Every 100 hours
Check the hydraulic hoses for leaks, loose fittings,
kinked lines, loose mounting supports, wear, weather
and chemical deterioration. Make necessary repairs
before operating.
Note: Keep areas around the hydraulic system clean
from grass and debris build up.

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.
Setting the Hydraulic Pump
Neutral Position
Note: Adjust the handle neutral first. That needs to be
correct before the following adjustment can be made.
This adjustment must be made with drive wheels turning.
DANGER
Mechanical or hydraulic jacks may fail to support
machine and cause a serious injury.
• Use jack stand when supporting machine.
• Do not use hydraulic jacks.
WARNING
Engine must be running so motion control
adjustment can be performed. Contact with moving
parts or hot surfaces may cause personal injury.
Keep hands, feet, face, clothing and other body
parts away from rotating parts, muffler and other
hot surfaces.
1. Raise the frame and block up the machine so drive
wheels can rotate freely.
2. Disconnect the electrical connector from the seat
safety switch. Temporarily install a jumper wire
across terminals in the wiring harness connector.
3. Unlatch the seat and slide seat forward.
4. Disconnect the seat rod and tilt the seat fully forward.
