General Operation and In-Field
Adjustments
1. Raise the disk completely and unfold the machine.
Make sure the fold cylinders are fully extended to
allow the wings to fully flex in the field. Proceed into
the field and lower the machine to the desired oper-
ating depth.
2. If satisfied, set the depth and then proceed through
the field, observing the disk for levelness, side to
side and fore to aft. Although the disk was preset,
See “First time Field Adjustments” on page 17, to
level machine. Certain field conditions can cause the
disk to vary from center to wings and front to rear
when being pulled through the ground. A final adjust-
ment may need to be made to the disk harrow.
3. If the center is running deeper because of it following
the tractor in soft soil, the wings may need to be set
in slightly deeper (with the eyebolts) and then the
entire machine set slightly shallower (with depth
stop).
