General Operation and In-Field Adjust-
ments
23. Remove the transport lock pins and unfold the
machine. Make sure the fold cylinders are fully
extended to fully flex in the field.
24. If possible have someone observe the machine during
first time operation for levelness, front to rear and
wings to center frame.Adjust each as needed.
Front to Rear Leveling
Refer to Figure 7
25. Lower the machine to the desired working depth and
then level the machine from front to rear if needed.
Model 9322 will have a turnbuckle to adjust and models
9326-9756 will have an eyebolt (shown). Loosen jam
nut
on either the turnbuckle or eyebolt and adjust
other nut up or down, moving front of hitch until
machine is level front to rear for most conditions.
Retighten jam nut to secure.
26. The front could be adjusted slightly lower for hard soils.
Do not adjust too much lower. Never run machine with
the back lower (deeper) than the front.
27. Once the machine is leveled front to rear the treaders
may be adjusted. In most cases the treader should be
allowed to float and will not require additional down
pressure.
28. The machine may need some additional adjustment
from side to side, See “Side to Side Leveling” on
page 15. Adjust the inside wings first, then the outside
wings.
Gauge Wheel Adjustment
Refer to Figure 8
29. Once the machine has been adjusted and set to the
desired working depth, you may now adjust the gauge
wheels.
30. To adjust the gauge wheel arm , loosen the two 3/4
bolts . Remove pin and slide gauge wheel arm up
or down until the gauge wheel is 1/2” to 1 1/2” above
ground.
31. Re-instal the pin and tighten the two 3/4 bolts .
32. The ideal working speed for the Plains Plow is 5 1/2 to 6
1/2 mph. Working too slow may cause plugging, poor
incorporation or mixing crop residue and reduced weed
kill. Running too fast may cause streaks in chemical
incorporation and ridging.
