Coulter Wing Adjustment
Set the coulter wing frames so the wing coulters run at
exactly the same depth as the center frame coulters. This
is accomplished with two adjustments.
Refer to Figure 26
1. Add or remove spacer shims from behind coulter
frame stop studs. The studs should allow the coulters
to drop slightly below the desired operating depth to
allow the coulter lock pins to be installed and removed
easily.
Refer to Figure 27
2. Adjust the lock link trunnion nuts so the wing coulters
run exactly the same depth as the center frame coul-
ters. The coulters must be lowered into the ground so
soil pressure is forcing the wings upward to make sure
the lock link trunnions are properly set.
