Adjusting the Reverse-Stop
Rod
1. Stop the machine and move the speed control lever to
the neutral position.
2. Disengage the PTO, engage the parking brake, stop the
engine, and wait for all moving parts to stop.
3. Check the movement of the steering levers as follows:
•
If the levers move slightly forward up to 3 mm
(1/8 inch) then no adjustment is necessary.
•
If the levers do not move, then proceed with the
following steps:
A. Flip up the seat up or remove the seat frame
assembly (with the seat attached) to obtain
a clear view of the steering control shaft to
complete this adjustment.
B. Place the speed control lever in the neutral
position.
C. Release the parking brake.
D. Slightly adjust the length of the rod by
loosening the jam nut and by rotating the rod.

Adjusting the Speed-Control
Lever Tension
1. Stop the machine and move the speed-control lever to
the neutral position.
2. Disengage the PTO, engage the parking brake, stop the
engine, and wait for all moving parts to stop.

located at the end of the motion control shaft in front
of the righthand console (Figure 56).
Note: Set the tension high enough that the speed
control lever position is maintained during operation
and loose enough to be moved comfortably by the
operator.
