Marker Setup
Refer to Figure 14
Markers are field-installed, but usually do not have their
extension length
precisely set. The drill must be lev-
eled per “Leveling the Drill” on page 84, and marker(s)
must be in correct working order per “Marker Mainte-
nance” on page 87.
Row unit centerline stations on 2S-2600HD drills are
symmetrical about machine center, so left and right
extensions are normally identical, for both opposing and
concentric passes.
Set the initial length of the marker(s) as follows:
1. With drill unfolded, lower drill and openers to field
position (“Raising and Lowering Openers” on page
24).
2. Extend a marker on one side. Pull forward several
feet to leave a mark.
3. Sighting parallel to the main tool bar, measure
from the centerline of the left outside row unit to the
mark.
4. Adjust the marker extension so that the mark is
one half the span plus one row unit spacing .
See “Marker Adjustments” on page 70 for setting
marker extension.
5. Pull forward several feet, and re-measure to verify
any adjustment. Validate the mark by making a pass
to one or both sides.
6. Fold marker. Extend other side and adjust.
Point Row Cab Module
If your drill has the Point Row option, the cab module
may already have been installed by your dealer. If not,
consult the installation instructions for the option, and
mount the module in a convenient location.
Note: If field conditions require inverting the marker disk
(page 72), the mark moves, and the extension
needs to be re-measured and reset. Marking also
changes slightly if the opener frame trunnion posi-
tion is changed (page 64).
