Marker Disk Adjustment
!
CAUTION
Marker disks may be sharp. Use caution when making adjust-
ments in this area.
Refer to Figure 43
To change angle of cut, and the width of the mark, loosen
1 ⁄
2
-inch bolts holding disk assembly.
For a wider mark (W), increase the angle of the marker
with respect to the tube
. For a narrower mark (N),
reduce the angle.
Tighten bolts .
Note: The direction of travel (T) tends to drive the disk an-
gle to Wide. If bolts are not tight enough, or loosen
over time, the disk will slip into the Wide mark con-
figuration.

switch
that is used to activate the Drive when the
planter is lowered for field operation.

ery should begin.

secure it in place. Be sure frame tube will not crush
