Marker Assembly
15- or 20-Foot Markers
1.
Lower drill into field position. From end of each drill box, al-
low 9 feet of clearance on a 15-foot drill or 11 feet of clear-
ance on a 20-foot drill for marker assembly.
2.
Mount first marker section (1) on lower 3 1/2-inch frame
tube. Mount marker as close to end of frame as
possible. Mount with 5/8-inch u-bolts (7), hex
nuts (9) and lock washers (8).
3.
Remove port plugs from cylinder so you can
extend fold cylinder. Unfold first section and
lift hinge.
4.
Align holes in second section (2) with
holes in lift hinge. Bolt sections together
with 5/8-inch bolt (5), lock nut (6), 3/8-inch
shear bolt (4) and lock nut (3). Assemble
sections so stop block on second section
faces up.
5.
On 20-foot drills,
mount support arm (14) at dimension
shown using clamp plates (10),1/2-inch u-bolts (11), hex
nuts (12) and lock washers (13).
6.
Mount support-arm saddle (18) to support arm with 1/2-inch
u-bolts (17), lock washers (15) and hex nuts (16). To prevent
wear when folded, center saddle under the square tube of
second section.
7.
Adjust support arm and saddle so second section is parallel
with seed-box lid when marker is folded.
8.
If necessary, repeat steps
to mount other marker.
After assembling markers, proceed
to Hydraulic Setup, page 3.
