7. Bolt the chain bar weldment (1) to the first
section (2) with 3/8” x 3 1/4” long bolt (3) and
lock nut (4). The chain bar weldment (1)
should pivot freely on the 3/8” bolt (3). Bolt the
chain bar (5) to the third section (6) with the
3/8” x 1 1/2” long bolt (7) and lock nut (4). The
chain bar (5) should pivot freely on the 3/8”
bolt (7). Connect the marker chain (10) be-
tween the chain bar (5) and chain bar weld-
ment (1) with 5/16” utility clevis (9). With the
marker disk adjusted for seeding width and
disk touching the ground, adjust chain length
to remove the slack. Adjustment should be
made at the utility clevis (9) nearest to the
drill.
8. The purpose of the 3/8” x 2 1/2” long stop bolt
(11) is to hold tension on the marker chain
(10) ONLY when the marker is in folded posi-
tion. Therefore; the 3/8” stop bolt (11) and
lock nuts (4) should be positioned in the first
section (1) so the head of the stop bolt ex-
tends as little as possible. After marker is fold-
ed, adjust stop bolt to tighten chain.
Refer to Figure 5
9. When mounting the marker carrier arm (1), on
the 455, first mount the transport mount arm
(2) to the drill frame using 3/8” x 6" x 7" long u-
bolt (3), flat washers (4), and flanged nuts (5).
The transport mount arm should be 45" - 55"
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.
10. Mount the support arm saddle (8) to the
marker carrier arm (1) with 1/2” x 2" x 3" long
u-bolts (6), flat washer (9), 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.
