Marker Disk Adjustment
Sharp Object Hazard:
Marker disks may be sharp. Use caution when making adjust-
ments in this area.
Adjusting Mark Width
Refer to Figure 66
is the direction of travel.
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.
Tighten bolts .

Marker Chain Length
Refer to Figure 68
With marker unfolded, adjust chain to a length
of 63in (160cm)
Slowly fold marker while observing disk. If marker disk
slides across the ground more than a foot (0.3m) before
chain and linkage lifts it up, the chain is too long.
Remove bolt and shorten chain one or two links.
Check adjustment by repeating folding process.
If chain is too short when marker is unfolded, it will pre-
vent the marker blade from dropping into field depres-
sions, causing skips in the mark line. Correct this
condition by lengthening chain one or two links.
