Disk Adjustment
The aggressiveness and the mark left by the disk may be
changed by two methods:
1. Angle of Cut. Refer to Figure 3-15. To change the an-
gle of cut, loosen the two 1/2-inch bolts holding the
disk assembly. Rotate the disk assembly as desired.

Disk Angle
2. Direction of Cut. The disk may be mounted to throw
dirt in or out for different marks in different soil condi-
tions. Refer to Figure 3-16. To change the direction of
cut:
a. Reverse the disk by removing the four lug bolts on
the disk hub. Remount the depth band and lug
bolts.
b. Turn the entire disk assembly by removing the two
1/2-inch bolts and turning the assembly one-half
turn. Reinstall the 1/2-inch bolts and set the disk
angle as desired.
IMPORTANT: To prevent marker damage, the marker
arm is attached to the marker body with a 7/16-inch,
grade 5 shear bolt. See Figure 3-14. If it breaks, you
must replace it with a grade 5 bolt. The bolt is Great
Plains part number 802-234C.

Folding Speed
The dual markers are equipped with hex-head screws to
adjust folding speed. The screws are on the sequence-
valve body as shown in Figure 3-17. There are two
screws–one controls folding speed (1), the other controls
unfolding speed (2). Turn the adjustment screws clock-
wise for slower folding or counterclockwise for faster fold-
ing. Adjust to a safe speed. Excessive speed could
damage the markers and void the warranty.
