Pre-Emergence Marker Setup
Pre-emergence, or tramline markers may have been
dealer-installed, but may not be optimally set for your
intended operations.
The markers are normally set to mark directly behind row
units controlled by tramline clutches. The factory default
for tramline rows is 4 and 16 (counting from row 1 at drill
left end). However, tramline rows can be any two of 1, 4,
6, 13, 14 or 16, plus an optional third clutch on row 13.
Refer to Figure 26
The position of the mount
on the tool bar also
depends on whether the marker disks are oriented to
the right of the marker arms (as shown) or to the left.
Determine disk orientation before adjusting mount loca-
tion.
To adjust mount location:
1. Adjust disk if necessary (below).
2. Loosen four nuts on the U-bolts.
3. Loosen four bolts through the walkboard. If the
mount must be moved more than a few cm, remove
these bolts entirely.
4. Slide the mount until the disk blade is directly in
line with the opener controlled by the tramline clutch.
5. Re-insert the walkboard bolts if removed.
6. Tighten the U-bolt nuts and the walkboard bolts.
Tramline Marker Disk Setup
Refer to Figure 27
The marker disks
can be installed on either side of the
marker arm (by reversing the wrist weldment ), and at
arbitrary vertical and horizontal angles.
1. Using the lower bolts , initially set the vertical angle
of the disk to perpendicular to the ground. Adjust it
later if the available range of horizontal angles does
not produce a satisfactory mark.
2. Using the upper bolts , adjust the horizontal angle
to produce a mark of the desired width. Pivot forward
to throw dirt out. Pivot aft to throw dirt in.
To reverse the disk entirely, remove the upper bolts and
rotate the wrist one half turn.
After any adjustments, make sure the mark centerline is
still aligned with the tramline row opener.
