47 Adjustments
Marker Chain
There are two, interrelated adjustments for the
marker chain. Make these adjustments in the fol-
lowing order.
Refer to Figure 57
1. Lifting Slack. With marker unfolded, back
full-threaded adjustment bolt (1) 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 cle-
vis (2). 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 length-
ening chain one or two links at clevis (2).
2. Folding Slack. Fold marker. Use full-threaded
adjustment bolt (1) 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 (3) on either side of upright
channel (4).
Transport Carrier
When marker is folded, the second section should
rest in transport-carrier saddle.
Refer to Figure 58
To adjust front-to-rear position of saddle, loosen
the 5/8 X 7-inch u-bolts (1) that fasten transport-
carrier mount onto box frame. Slide transport-car-
rier assembly forward or back as needed.
To adjust height of saddle, loosen 1/2-by-2-inch u-
bolts (2) that hold carrier tube to mounting brack-
et. Slide carrier tube up or down as needed.
