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.
