Feeler gauge
•
If the gap is less than 0.010 inch, then
reinstall the shim and reference the
Troubleshooting
section.
•
If the gap is sufficient, proceed to the
safety check in step F.
F. Perform the following safety check:
a. Sit on the seat and start the engine.
b. Make sure the blades Do Not engage with
the PTO switch “off ” and the clutch
disengaged.
If the clutch does not disengage,
reinstall the shim and reference the
Troubleshooting
section.
c. Engage and disengage the PTO switch
ten consecutive times to ensure the clutch
is functioning properly. If the clutch
does not engage properly, reference the
Troubleshooting
section.
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 adjustments 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 37). 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.
