ADJUSTMENTS/
ELECTRICAL SYSTEM
PTO Belt Tension
PTO belt tension can be adjusted by lengthening or
shortening the position of the adjustment bolt on the
idler adjuster (above idler pulley). Optimum adjust-
ment will result in a 1/2
(1.27 cm) deflection of the
belt.
PTO Belt Tension Adjustment
PTO Clutch
The declutched or disengaged position of the PTO
clutch is adjustable and is set to completely release
spring tension on the mechanical clutch. The
spring in the linkage that engages the clutch should
not have any tension on it when the clutch is
disengaged. Adjust the PTO clutch engagement
adjustment bolt up or down to allow minimal free
movement in the disengaged position. If this can
not be achieved, the clutch rod will need to be
adjusted.

NOTE: When making any of the above adjustments,
it is important that the overall length from the top of
the clutch engagement spring to the lower mounting
of the clutch actuator link be 4 inches (10.2 cm) when
engaged.
Clutch Rod
The clutch rod and ball joints are factory adjusted to
10-1/8 inch (25.72 cm) overall length. Increasing the
length will increase the free movement of the spring
on the clutch engagement arm. Decreasing the
length will increase the amount of spring stretch in the
engaged position. (Refer to PTO Clutch Adjust-
ment - Engaged illustration.)
