Maintenance
WARNING
Engine must be running and drive wheels must be turning so park brake adjustment can be performed. Contact with moving parts or hot surfaces may cause personal injury.
Keep fingers, hands, and clothing clear of rotating components and hot surfaces.
F.Release the park brake so the handle rests on the 1/2 x 6 inch rod or bolt.
G.Move the throttle to high idle.
H.Move both motion control levers to the full forward position and hold for 15 seconds.
I.Move both motion control levers to the full reverse position and hold for 15 seconds.
J.Turn off the engine and completely release the park brake by removing the 1/2 x 6 inch rod or bolt.
K.Allow the hubs to cool until they are cool enough to safely touch.
L.Rotate the drive wheel release handle to the “released” position. Refer to the Drive Wheel Release Valves section in Operation.
M.Readjust both brakes following the procedure in steps 10 through 14.
18.Rotate the drive wheel release handle to the “operating” position. Refer to the Drive Wheel Release Valves section in Operation.
19.Install the rear tires and torque lug nuts to
20.Remove jack stands.
Electric Clutch Adjustment
No adjustment necessary.
Motion Control Linkage Adjustment
Located on either side of the fuel tank, below the seat are the pump control linkages. Rotating the pump linkage with a 1/2 inch wrench allows fine tuning adjustments so that the machine does not move in
neutral. Any adjustments should be made for neutral positioning only.
WARNING
Engine must be running and drive wheels must be turning so motion control adjustment can be performed. Contact with moving parts or hot surfaces may cause personal injury.
Keep fingers, hands, and clothing clear of rotating components and hot surfaces.
1.Prior to starting the engine, push the deck lift pedal and remove the height of cut pin. Lower deck to the ground.
2.Raise the rear of machine up and support with jack stands (or equivalent support) just high enough to allow drive wheels to turn freely.
3.Remove the electrical connection from the seat safety switch, located under the bottom cushion of the seat. The switch is a part of the seat assembly.
4.Temporarily install a jumper wire across the terminals in the connector of the main wiring harness.
5.Start engine. Brake must be engaged and motion control levers out to start engine. Operator does not have to be in the seat because of the jumper wire being used. Run engine at full throttle and release brake.
6.Run the unit at least 5 minutes with the drive levers at full forward speed to bring hydraulic oil up to operating temperature.
Note: The motion control lever needs to be in neutral while making any necessary adjustments.
7.Bring the motion control levers into the neutral position. Adjust pump control rod lengths by rotating the double nuts on the rod in the appropriate direction until the wheels slightly creep in reverse (Figure 34). Move the motion control levers to the reverse position and while applying slight pressure to the lever allow the reverse indicator springs to bring the levers back to neutral. The wheels must stop turning or slightly creep in reverse.
