Assembly and Setup Instructions
Marker Assembly
Refer to Figure 1.
1. Park the drill in an area large enough for folding and unfolding the assembled markers. A single marker will increase
the width of the drill by 15 feet.
2. Unfold and lower the drill. Park and shut off the tractor.
3. The marker sections are pre-assembled and banded together for shipment. Unpack the shipment and group the assemblies according to right-hand or left-hand.
!
Do not lift the assemblies unassisted. Lifting the assemblies without
mechanical aid could cause severe injury. Use a forklift or hoist to
move the assemblies during installation, or disassemble the assemblies
into smaller pieces before installation.
You could be severely injured by a failing assembly. Obey all safety instructions from lifting-equipment manufacturer. Do not walk or place
any body part under the raised sections. Be sure lifting equipment has
enough capacity.
NOTE: These instructions explain how to assemble the marker
if the sections are completely disassembled. If you do not have
adequate lifting equipment, disassemble the sections before
proceeding. If you do have a forklift or hoist large enough to lift
the pre-assembled sections, you can skip many of the following
steps.
4. Install the left-hand marker mount (1) on the left wing (2) of

WARNING!
the drill. Install the mount on the marker mount pads at the
end of the wing frame. Fasten the marker mount to the
mount pad (12) and the "A" cylinder gusset (13) with 3/4" x
2 1/4" bolts (3), lock washers (4), andnuts (5). Install the first
section of the marker (6) on the mount (1) by pushing the
pivot shaft (7) through the pivot holes on the mount and the
first section. Use the bolt (8) and lock nut (9) to secure the
shaft.
Mount the left-hand breakaway hinge (10) onto the first section (6) by pushing the pivot shaft (11) through the pivot
holes in each part. Use
the bolt (8) and lock nut
(9) to secure the shaft.

Refer to Figure 2.
5. Pin the base end of the hydraulic cylinder (12) to the marker
mount (1) using the pin and clip (13 and 14). Remove the
plastic plugs from the cylinder ports. Pull the rod end of the
cylinder out to its maximum length. Pin the rod end of the
cylinder to the breakaway hinge using the cylinder pin (15),
flat washers (16) and cotter pins (17) provided.
6. Install the chain bar (18) on the first section (6) with the bolt
(19) and lock nut (20). The chain bar should pivot freely
around the bolt (19).
7. Install the full-threaded adjustment bolt (21) in the hole directly above the pivot bolt (19). To install, first thread one
lock nut (22) up the entire length of the adjustment bolt.
Next, push the bolt with nut through the hole. Complete the
assembly by threading a second lock nut (22) up the entire
remaining length of the adjustment bolt.
After marker assembly, use the adjustment bolt to control
folding slack. For now, turn the adjustment bolt so its head
extends as little as possible to prevent damage the first time
the marker is folded.
8. Thread a utility clevis (23) through one end of the chain (24).
Pin this clevis to the chain bar (18) using the pin and cotter
pin (25 and 26) provided. Do not fully bend the cotter pin at
this time. Thread a second utility clevis (23) through the last
link at the opposite end of the chain (24). Pin this clevis to
the rounded end of the chain bar (27) using the pin and cotter pin (25 and 26) provided.

9. Attach the second section (28) to the breakaway hinge (10)
with the pivot pin (29). Secure the pivot pin (29) with the bolt
and lock nut (8 and 9). Complete this joint by passing the
grade 5 breakaway bolt (30) through the holes in the hinge
and second section. Install the lock washer (31) and nut (32)
on the breakaway bolt.
IMPORTANT: The breakaway bolt (30) is a 7/16 x
2 1/4-inch, grade 5 (G.P. # 802-234C). It is identified as a
grade 5 by having three marks on the head. If it breaks, replace it with an equivalent grade 5 bolt to prevent marker
damage.
Refer to Figure 4.
10. Attach the third section (33) to the second section (28) by using the pivot pin (29). Secure the pivot pin with the bolt (8) and
lock nut (9).
Fasten the loose end of chain bar (27) to the ears on the
third section (33) by using the bolt (34) flat washers (35) and
lock nut (36). Do not over tighten this pivot, which would
cause the ears to bend in. The chain bar must pivot freely
around the bolt.
