Disk Adjustment
There are two ways you can change the mark left by the
marker disk. Refer to Figure 3-21.
1. Disk Angle. To change angle of cut, loosen 1/2-inch
bolts holding disk assembly. Rotate disk assembly as
desired.
2. Direction of Cut. To change direction of cut and throw
dirt either in or out:
a. Reverse blade and depth band by remounting lug
bolts on disk hub.
b. Reverse angle of assembly by removing two 1/2-
inch bolts holding disk assembly. Turn disk as-
sembly one-half turn. Reinstall 1/2-inch bolts and
set disk angle.

Marker Chain
There are two, interrelated adjustments for the marker
chain. Make these adjustments in the following order. Re-
fer to Figure 3-20.
1. Lifting Slack. With marker unfolded, back full-thread-
ed adjustment bolt (1) down until head extends as little
as possible. Slowly fold marker while observing disk. If
marker disk slides across ground more than a foot be-
fore chain and linkage lifts it up, the chain is too long.
Shorten chain one or two links by moving clevis (2).
Check adjustment by repeating folding process.
If chain is too short when marker is unfolded, it will
prevent end of marker from dropping into field depres-
sions, causing skips in your marker line. Correct this
condition by lengthening chain one or two links at cle-
vis (2).
2. Folding Slack. Fold marker. Use full-threaded adjust-
ment bolt (1) to take slack out of chain while marker is
folded. Extend bolt until there is no chain slack. Lock
bolt in this position by tightening nuts (3) on either side
of upright channel (4).
