Marker Disk Adjustment
Sharp Object Hazard:
Use caution when making adjustments in this area. Marker
disks may be sharp.
Refer to Figure 69
1. To change angle of cut, and the width of the mark,
loosen
3
/
8
inch bolts holding the disk assembly.
For a wider mark , increase the angle of the
marker with respect to the tube . For a narrower
mark , reduce the angle.
 Do not set a marker angle wider than need to make a
useful mark. Excess angle increases wear on all
marker components.
2. Tighten bolts .
 The direction of travel tends to drive the disk angle
to Wide. If bolts are not tight enough, or loosen over
time, the disk will slip into the Wide mark
configuration.
Marker Extension
Marker width needs to be adjusted once for the initial
YP2425A Planter setup, and later only if changing row
spacing (including locking up row units for single-row
operation on a twin-capable planter).
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
table at right. Extension distance is the same for both
planter sides unless otherwise noted.
Refer to Figure 70 and Figure 71
3. Measure out the Extension distance from the
center-line of each outside 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 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 the mark locations. Adjust to obtain the table
value.
