To Adjust
• Open the clutch access window which is located
on the right front of the clutch housing.
• Insert a 0.098 to 0.12 inch (2.5 to 3.0 mm) feeler
gauge between the release thrust bearing and
the release levers. Adjust the clearance by
adjusting the length of the clutch rod.
- Lengthen the rod if the clearance is wider than
the specification.
- Shorten the rod if the clearance is less than the
specification.
• Depress the clutch pedal and check to make
certain that the free travel at the tip of the pedal is
1.57 to 1.96 inches (40 to 50 mm).
• With the clutch pedal fully depressed, confirm
that there is adequate gap between the clutch rod
and the safety start switch.
IMPORTANT: When adjusting the clutch pedal free
travel, always use measuring devices rather than
visually estimating distances.
ADJUSTING THE MICRO SWITCH HEIGHT
The PTO micro switch, located on the right fender
aside the position control lever, is initially set so that
the PTO will disengage when the 3-point hitch lower
links are raised to approximately 23.6 to 26 inches.
See Figure 44.
Figure 44
If your application requires the PTO to run with the
lower links at a height above 23.6 to 26 inches, the
micro switch position can be adjusted as follows:
• Loosen the screws securing the micro switch
mounting bracket. Refer to Figure 45.
Figure 45
• Raise the switch slightly and recheck the position
of the lower links when the PTO shuts off.
• If necessary, repeat the above step until the PTO
shut-off height of the lower links is adequate for
your application. The switch can be adjusted so
that the lower links can be raised to approxi-
mately 35.8 inches before the PTO will be
disengaged.
ADJUSTING WHEEL TREAD
When operating the tractor in the field, it is sometimes
necessary to change the rear wheel tread to a
narrower position to avoid plant rows, or to widen the
tread to improve stability when operating on slopes.
The rear wheel tread width can be adjusted to any of
6 different positions ranging from 46.4 to 58.6 inches
by changing the position of the wheel disc relative to
the rim mounting brackets and the rear axle.
Figure 46
IMPORTANT: The front wheel tread width cannot be
adjusted. Attempting to do so will cause damage to
the tractor. If removed, torque front wheel lug nuts to
57.2 - 66.5 ft. lbs.
23.6 - 26.0 in.
