INSTALLATION INSTRUCTIONS FLAT FOLD MARKER

FOR THE FOLLOWING ASSEMBLY INSTRUCTIONS, REFER TO THE ILLUSTRATION ON
PAGE1-3. See the "Parts Section" of this manual to identify individual components not mentioned in
these installation instructions.

Place drill in a lowered field position. From each end of the drill box allow 16 ft. clearance for

marker assembly.

Attach the marker first section with mount (#1) to the marker mounting on the drill frame as il-

lustrated. Mount the 5/8" x 2" long u-bolts (#32), lock washers (#9), and hex nuts (#10).

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 first section and the lift lug (#1) to a horizontal
position.

With the stop block positioned on top of second section (#2), align the holes of the second sec-

tion with the holes of the first section (#1) and bolt together with the 5/8" x 5 1/2" long bolt (#5), lock
nut (#4), 3/8" x 2" long shear bolt (#6), and lock nut (#7).

Place the third section (#3) over the end of the second section (#2) and insert hinge pin (#19)

through the second and third section pivot. Secure the hinge pin (#19) with 1/4" x 2" long bolt (#17)
and lock nut (#16).

Bolt the chain bar weldment (#13) to the first section (#1) with 3/8" x 3 1/4" long bolt (#11) and

lock nut (#7). The chain bar weldment (#13) should pivot freely on the 3/8" bolt (#11). Bolt the chain
bar (#18) to the third section (#3) with the 3/8" x 1 1/2" long bolt (#21) and lock nut (#7). The chain
bar (#18) should pivot freely on the 3/8" bolt (#21). Connect the marker chain (#15) between the
chain bar (#18) and chain bar weldment (#13) with 5/16" utility clevis (#14). 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 (#14) nearest to the drill.

The purpose of the 3/8" x 2 1/2" long stop bolt (#12) is to hold tension on the marker chain (#15)

ONLY when the marker is in folding position. Therefore; the 3/8" stop bolt (#12) and lock nuts (#7)
should be positioned in the lift arm (#1) so the head of the stop bolt extends as little as possible. After
marker is folded, adjust stop bolt to tighten chain.

When mounting the marker carrier arm (#27), on the 3-Section Drill, first mount the transport

mount arm (#26) to the drill frame using 3/8" x 6" x 6 3/4" long u-bolt (#22), flat washers (#20), lock-
washer (#23), and nuts (#24). The transport mount arm should be 50" - 60" away from the box end
as shown. Next attach the marker carrier arm (#27) to the transport mounting arm (#26) using the
1/2" x 2" x 3" long u-bolts (#30), lockwashers (#28), and nuts (#29). The marker carrier arm should
be set at 31 3/8" - 31 7/8" above the drill frame as shown.

Mount the support arm saddle (#31) to the support arm (#27) with 1/2" x 2" x 3" long u-bolts

(#30), lock washers (#28), and hex nuts (#39). The support saddle should be centered under the
marker chain and the square tube of the second section (#2), when folded to prevent wear. The sup-
port 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 (#30) up or down to
parallel the marker with the drill box lid.

10. Fold the marker to transport position. With the marker chain (#15) in the slot of the support arm
saddle (#31), take up the slack in the marker chain by threading 3/8" x 2 1/2" long stop bolt (#12) out
against the chain bar weldment (#13), lock this stop bolt in position with the two lock nuts (#7).
