Marker Extension
Prior to first use, and if row spacing is changed (including
locking up row units for single-row operation on a twin-
capable planter), set and check where the mark is made
on each side relative to the outside row units (whether
outside rows are in use or not).
Overhead Sharp Object Hazard:
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 planter when folding or
unfolding the markers.
1. Move the planter to a location where both markers
may be safely unfolded. Unfold the planter. Lower
the planter. Unfold one marker.
2. Find the suggested initial marker Extension in the
tables.
Refer to Figure 146 and Figure 147
3.
Measure out the Extension distance from the cen-
ter-line of each outside end row unit. Do not measure
to center of row pair.
4. Mark the ground at this point.
5. To adjust marker width, loosen nuts on U-bolts .
Move marker disk tube in or out to get the proper
adjustment. Tighten nuts .
6. Repeat step 3 through step 5 for the other side.
7. With the planter still lowered, drive forward a few feet
for each side.
8. Check mark locations. Adjust to obtain table value.
