Marker Chain - Lifting Slack
Refer to Figure 79
1.
With marker unfolded, adjust chain to a length of
67 inches (170 cm). Slowly fold marker while
observing disk. If marker disk slides across the
ground more than a foot before chain and linkage
lifts it up, the chain is too long.
2. 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
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.
