Marker Width
Refer to Figure 35
You will need to adjust marker width to account for your
row spacing. First determine the correct marker width
from the table and diagram on these pages, then adjust
the marker to the correct width. Finally, check the actual
marker width in the field and make further adjustments
as necessary.
To adjust marker width, loosen jam nuts (1) and1/2-inch
set screws (2). Move marker disk tube (3) in or out to get
the proper dimension .
To check that the marker is adjusted to the correct width,
lower drill in the field and drive forward a few feet.
Measure from the middle of the outside row to the mark
in the ground made by the marker disk. The
measurement should match those shown in the
diagrams. Make further adjustments as necessary.
The diagram below shows marker width for 7 1/2-inch,
10-inch and opener spacing with all cups open.
