locking up row units for single-row operation on a
twin-capable planter), set and check where the mark is
made on each side relative to the outside row units
(whether in use or not).

center-line of each outside end row unit. Do not
measure to center of row pair.

Mark the ground at this point.
5.
To adjust marker width, loosen nuts
on U-bolts
.
Move marker disk tube
in or out to get the proper
adjustment. Tighten nuts
