1. Placedrill in a loweredfieldposition. Fromeachend
of the drill box allow 16 ft. clearance for marker
assembly.
Refer to Figure 1
2. Attach the marker first section with mount (4) to the
drill frame as illustrated using the 3/4" x 6 1/32" Ubolts (1), 3/4" flat washer (2) and 3/4" locking flange
nut (3).
Refer to Figure 2
3. Assemble the marker in a horizontal position,
remove the port plugs in the hydraulic cylinder to
allow the fold cylinder to be extended. Then fold the
firstsection andthe liftlug channel(1) toahorizontal
position.
4. With the shear bar positioned towards the front (2),
align the holes of the second section with the holes
of the lift lug channel (1) and insert the hinge pin (9)
and bolt into place with 5/16" x 2" Gr 5 bolt (4) and
locknut (5). Also place the 7/16" x 2 1/4" Gr 5 shear
bolt (6) in position with lock washer (7) and nut (8).
Refer to Figure 3
5. Placethethird section(1) overtheend ofthesecond
section (13) and insert hinge pin (9) through the
secondandthirdsection pivot. Secure the hinge pin
(9) with 5/16" x 2" long bolt (5) and lock nut (4).
6. Bolt the chain bar weldment (14) to the first section
(18) with 3/8" x 3 1/4" long bolt (16) and lock nut (6).
The chain bar weldment (14) should pivot freely on
the 3/8" bolt (16). Bolt the chain bar (10) to the third
section(1) with the3/8" x 11/2" long bolt(8),washer
(7) and lock nut (6). The chain bar (10) should pivot
freely on the 3/8" bolt (8). Connect the marker chain
(2) between the chain bar (10) and chain bar
weldment (14) with 5/16" utility clevis (11). 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 (11) nearest to the drill.

tohold tension onthe marker chain(12) ONLY when
the marker is in folded position. Therefore; the 3/8"
stop bolt (17) and lock nuts (6) should be positioned
in the first section (18) so the head of the stop bolt
extends as little as possible. After marker is folded,
adjust stop bolt to tighten chain.
