Transport Carrier Adjustment
Refer to Figure 19
When marker is folded, the second section should be
centered in transport carrier saddle
and be parallel
with top of markers box.
To adjust height of saddle, loosen
1 ⁄
2
×2 inch U-bolts
that hold the carrier tube to the mounting bracket. Slide
carrier tube up or down as needed.
Check Slack and Stop Bolt
There are two, interrelated adjustments for the marker
chain. Make these adjustments in the following order.
Refer to Figure 20
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 12 inches
(30 cm) 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.
