and turning knob clockwise to tighten, or counterclockwise
to loosen, then retighten set screw.

6—ADJUSTMENTS
Read each instruction completely and, make sure you under-
stand it before making any adjustments. Follow all the safety
precautions.
To avoid possible serious injury, before making
any adjustments or performing maintenance, en-
gage parking brake, place all tractor controls in
neutral, lower decks to the ground, turn ignition
switch “off” and remove key.
6.1--TRACTION PEDAL ADJUSTMENTS
The traction pedal (1, Fig.M) is equipped with a safety switch
(2, Fig. M) and a neutral centering device. The switch prevents
the engine from starting when the pedal is positioned in
reverse or forward. The centering device locates neutral
positioning of the pump.
1. Prior to adjusting for creep, elevate the wheels off the
ground and support the vehicle with jack stands. Any
adjustments should be done while the hydraulic oil is
warm.
2. To adjust the creep of the drive wheels, loosen the
fastener attaching the clevis to the control arm. Rotate the
clevis and re-atach to achieve neutral.
3. Once the traction pedal has been adjusted, the safety
switch (2, Fig. M) should not have to be re-adjusted.
Check neutral switch operation before use. If needed,
adjust the switch so that the engine cannot be started
unless the pedal is in the neutral position.
