MAINTENANCE
Miscellaneous
Standard and 4 Wheel E-Z Tow Pivot
Pivot Mounted Auto Reverse Adjustment
Two heavy duty limit switches are mounted by a
bracket attached to the split ring. The switches re-
main stationary with the riser pipe. See Figure 74-1.
The actuator bolt is mounted to roller plate. See Fig-
ure 74-1.
Switch Adjustment
Position each of the switch brackets in the appropri-
ate position on the split ring. Adjust the switches in
the slots of the actuator brackets corresponding to
the position where the center pivot is to change di-
rections.
NOTE
• A very small change in the location of either
switch can result in MUCH greater 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 switches have been installed
and initially adjusted, observe the pivot as it reverses
direction to insure it does not travel beyond the de-
sired reversing point(s). If necessary, readjust the
switch(s) until the center pivot reverses at the desired
point(s).
