Marker Disk Adjustment
Sharp Object Hazard:
Marker disks may be sharp. Use caution when making
adjustments in this area.
Refer to Figure 59
1. To change angle of cut, and the width of the mark,
loosen

-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.
Note:
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 .
Note:
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
YP24 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
following table. Extension distance is the same for
both planter sides unless otherwise noted.
Refer to Figure 60 and Figure 61
3. Measure out the Extension distance from the
center-line of each outside end row unit (or row unit
in use for twin-row in lock-up). 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.
