Marker Extension
Marker extension needs to be adjusted once for the initial
3PYPA planter setup, and later only if changing row
spacing (including locking up row units for single-row
operation on a twin-capable planter).
1. If changing between single- and twin-row operation,
first re-center the planter at the hitch. See page 14.
2. Move the planter to a location where both markers
may be safely unfolded. Unfold the planter. Lower
the planter. Tilt up and unfold one marker.
Find the suggested initial marker Extension in the fol-
lowing tables
Refer to Figure 164 and Figure 165
3.
Measure out the Extension distance from each out-
side end row unit (whether in use or not). 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 steps 3 and 5 for the other side.
7. With the planter still lowered, drive forward a few feet
for each side.
8. Check the mark locations. Adjust to obtain the table
value.
