Your life and the lives of others depend on it!
Before You Start
Starting on page 6 are detailed lists of parts included
in the marker packages. Use these lists to inventory
parts received.
!
You may be injured if hit by a folding or unfolding
marker. Markers may fall quickly and unexpectedly if
the hydraulics fail. Never allow anyone near the drill
when folding or unfolding the markers.
Escaping fluid under pressure can have sufficient pressure
to penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic
lines. Use a piece of paper or cardboard, NOT BODY
PARTS, to check for leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems.
If an accident occurs, see a doctor immediately. Any luid
injected into the skin must be surgically removed within a
few hours or gangrene will result.
CAUTION!

Assembly Instructions
Marker Assembly
Refer to Figure 1.
1. Lower drill into field position. Make sure the
assembly area is large enough for the drill
and markers (62 feet for a 30-foot drill or 50
feet for a 24-foot drill).
2. Attach the marker first section with mount
(1) to the lower 3 1/2-inch tube of the
drill frame. Mount the 5/8-inch ubolts (8), lock washers (9) and hex
nuts (10).
NOTE: On 24-foot drills with dual gauge
wheels, markers may not be applicable
due to problems with clearance. If using
markers on a dual gauge wheel 24’ drill,
mounting the markers and the marker carrier
arm on the top frame tube will be acceptable. It
may also be necessary to move the gauge
wheel assembly towards the inside of the drill.
3. Assemble the marker in a horizontal position. Remove the port plugs in the hydraulic
cylinder then fold the first section and the lift
lug (1) to a horizontal position.
4. With the stop block positioned on top of second section (2),
align the holes of the second section with the holes of the
first section (1) and bolt together with 5/8-by-5 1/2-inch bolt
(5), lock nut (4), 3/8-by-2-inch shear bolt (6) and lock nut (7).
5. 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-by-2-inch bolt (17) and lock nut (16).
6. Bolt the chain bar weldment (13) to the first section
(1) with 3/8-by-3 1/4-inch bolt (11) and lock nut
(7). The chain bar weldment (13) should pivot
freely on the 3/8-inch bolt (11). Bolt the
chain bar (18) to the third section (3)
with the
3/8-by-1 1/2-inch bolt (21) and lock nut
(7). The chain bar (18) should pivot
freely on the 3/8-inch bolt (21). Connect the marker chain (15) between
the chain bar (18) and chain bar
weldment (13) with 5/16-inch 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.
7. Position the 3/8-inch stop bolt (12) and lock
nuts (7) 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.
8. When mounting marker carrier (27), mount the marker carrier arm (27) to drill frame as noted in the illustration. Use the
clamp plates (22), 1/2-by-3 1/2-by-6 1/2-inch u-bolts (23),
lock washers (25), and hex nuts
(24). The carrier arm (27) should
be set 24 1/8 inches above
the drill frame.
NOTE: On 24-foot drills with
dual gauge wheels, mount carrier on top tube only. Discard one
clamp plate and its mounting
hardware. Set carrier arm (27) 32 5/8 inches above drill frame.
NOTE: On bean machines, use 1/2-by-7 1/32-by-8inch u-bolts to mount larger clamp plates on top frame
tube.
