2 Wheel E-Z Tow Pivot
Pivot Mounted Auto Reverse Adjustment
Two heavy duty limit switches are mounted by a
bracket attached to the roller plate.
The upper or top switch (auto reverse) changes
the direction of the center pivot from forward to re-
verse operation. See Figure 77-1.
The lower or bottom switch (auto forward) changes
the direction of the center pivot from reverse to for-
ward operation. See Figure 77-1.
Actuator bolts are mounted to actuator brackets that
are bolted on the split ring. The actuator bolts remain
stationary with the riser pipe.
The actuator bolt that points upward, changes the
direction of operation of the center pivot from reverse
operation to forward operation. See Figure 77-1.
The actuator bolt that points downward, changes
the center pivot direction from forward operation to
reverse operation. See Figure 77-1.
Actuator Bolt Adjustment
Position each of the actuator brackets in the appropri-
ate position on the split ring. Adjust the actuator bolts
in the slots of the actuator brackets corresponding
to the position where the center pivot is to change
directions.
NOTE
• A very small change in the location of either
actuator bolt causes a MUCH larger change
at the outer end of the machine. For example,
1/16 of an inch at the pivot equates to ap-
proximately 7 feet at the outer end of a typical
quarter section center pivot.
After the auto reverse actuator bolts have been in-
stalled and initially adjusted, observe the pivot as it
reverses direction to insure it does not travel beyond
the desired reversing point(s). If necessary, readjust
the actuator bolt(s) until the center pivot reverses at
the desired point(s).
