Refer to Figure 4
8. When mounting the marker carrier arm (1), first
mount the transport mount arm (2) to the drill frame
using 1/2" x 4 1/32" x 7 1/4" long U-bolt (3), flat
washers (4), and flanged nuts (5). The transport
mount arm should be 50" - 60" away from the box
end as shown. Next attach the marker carrier arm
(1) to the transport mounting arm (2) using the 1/2"
x 2" x 3" long U-bolts (6), flat washers (9) and
flanged nuts (7). The marker carrier arm should be
set at 31 3/8" - 31 7/8" above the drill frame as
shown.
9. Mount the support arm saddle (8) to the marker
carrier arm (1) with 1/2" x 2" x 3" long U-bolts (6),
and flanged nuts (7). The support saddle should be
centered under the marker chain and the square
tube of the second section, when folded to prevent
wear. The support arm should support the second
section parallel with the seed box lid. Adjustment
can be made by loosening the U -bolts that clamp
the marker carrier and slide marker carrier (1) up or
down to parallel the marker with the drill box lid.
Refer to Figure 5
10. Fold the marker to transport position. With the
marker chain (12) in the slot of the support arm
saddle, take up the slack in the marker chain by
threading
3/8" x 2 1/2" long stop bolt (17) out against the chain
bar weldment (14), lock this stop bolt in position with
the two lock nuts (6).
11. The marker blade comes factory assembled. The
width of the mark that the blade makes can be
adjusted by changing the angle of the blade. This is
done by loosening the two 1/2" bolts in the blade
adjuster, pivoting the blade to the preferred angle
and tightening the bolts.
Refer to Figure 6
12. If desired, the angle of the blade can be reversed by
turning the blade adjuster upside down and
reversing the blade so the depth band is on the
inside.
