Marker Setup
This section covers markers installed on the drill. For
markers installed on an accessory hitch, consult the
hitch and/or hitch-marker manual. Marker Extension data
in the Appendix of this manual applies to drill- or
hitch-mounted markers.
If drill-mounted markers were ordered as a separate
accessory, or were not dealer-installed, mount them per
the installation instructions supplied with the markers.
Marker Chain Adjustment
There are two, interrelated adjustments for the marker
chain. Make these adjustments in the following order.
Refer to Figure 22
Marker Lifting Slack
1.
Unfold marker.
2. Loosen jam nuts on both sides of channel at
adjuster bolt .
3. Thread bolt in (up) until head is flush with inside jam
nut and both are flush with inside of channel.
4. Slowly fold marker while observing disk. If marker
disk drags across ground more than 12in (30cm)
before lifting, the chain is too long.
5. Shorten chain one or two links by moving clevis bolt
up chain a few links. Check adjustment by
repeating folding process.
6. 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
1.
Fold marker.
2. Extend adjustment bolt to take slack out of chain
while marker is folded. Extend bolt until there is no
chain slack.
3. Lock bolt in this position by tightening jam nuts on
either side of upright channel.
