Marker Chain
Refer to Figure 37
There are two, interrelated adjustments for the marker
chain. Make these adjustments in the following order.
Lifting Slack. With marker unfolded, back full-threaded
adjustment bolt
down until head extends as little as
possible. Slowly fold marker while observing disk. If
marker disk slides across ground more than a foot before
chain and linkage lifts it up, the chain is too long.
Shorten chain one or two links by moving clevis .
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
depressions, causing skips in your marker line. Correct
this condition by lengthening chain one or two links at
clevis
.
Folding Slack. Fold marker. Use full-threaded
adjustment bolt
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
on either side of
upright channel .
Marker Disk Adjustment
Sharp Object Hazard:
Use caution when making adjustments in this area. Marker
disks may be sharp.
Refer to Figure 38
There are two ways you can change the mark left by the
marker disk.
Disk Angle
1. To change angle of cut, and the width of the mark,
loosen
1 ⁄
2
inch bolts holding the disk assembly.
For a wider mark , increase the angle of the
marker with respect to the tube . For a narrower
mark , reduce the angle.
Note: Do not set a marker angle wider than need to make
a useful mark. Excess angle increases wear on all
marker components.
2. Tighten bolts .
Direction of Cut
To change direction of cut and throw dirt either in or out:
Reverse blade and depth band by remounting lug bolts
on disk hub.
