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 it with jack stands.
2. Start the engine and run at low idle speed. Engage the
lever and traction on 1 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 of 2
minutes)
4. Check 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 buildup.
Setting the Hydraulic Pump
Neutral Position
Note: Adjust the handle neutral first. That needs to be
correct before you make the following adjustments.
You must make this adjustment 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
The engine must be running so that you can
perform a motion control adjustment. Contact with
moving parts or hot surfaces may cause personal
injury.
Keep your 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 wire-harness connector.
3. Unlatch the seat and slide seat forward.
4. Disconnect the seat rod and tilt the seat fully forward.
Setting the Right Hydraulic Pump
Neutral Position
1. Start the engine, open the throttle 1/2 way and release
the parking brake; refer to
Engine (page
21).
Note: You must put the motion-control lever in the
N
position while making any adjustments.
EUTRAL
2. Adjust the pump rod length by rotating the knob, in the
appropriate direction, until the wheel is still or slightly
creeping in reverse
3. Move the motion-control lever forward and reverse,
then back to neutral. The wheel must stop turning or
slightly creep in reverse.
4. Open the throttle to the F
the wheel remains stopped or slightly creeps in reverse,
adjust if necessary.
