Leveling marker disk (1515 only). If the marker disk is
not square with the ground when the marker is lowered in
the field, or if the marker arm tends to fold up while lowered
in the field, adjust the marker mount.
To adjust, loosen 1/2-inch bolts (1) and rotate marker
mount (2) until marker disk is square with the ground (3).

Disk Square
Marker Chain (2515 only)
There are two interrelated adjustments for the marker
chain. Make these adjustments in the following order. Re-
fer to Figure 3-20.
1. Lifting Slack. With marker unfolded, back full-thread-
ed 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 be-
fore chain and linkage lifts it up, the chain is too long.
Shorten chain one or two links by moving clevis (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 depres-
sions, causing skips in your marker line. Correct this
condition by lengthening chain one or two links at cle-
vis (2).

2. Folding Slack. Fold marker. Use full-threaded adjust-
ment 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).
