Marker Extension
Prior to first use, and if row spacing is changed (including
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 the outside rows are in use or not).

Move the planter to a location where both markers
may be safely unfolded. Unfold the planter. Lower
the planter. Unfold one marker.
2.
Find the suggested initial marker Extension
in the
tables.
Refer to Figure 160 and Figure 161
3.
Measure out the Extension
distance from the cen-
ter-line of each outside end row unit. Do not measure
to center of row pair.
4.
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
.
6.
Repeat step 3 through step 5 for the other side.
7.
With the planter still lowered, drive forward a few feet
for each side.

Check mark locations. Adjust to obtain table value.
