Marker Disk Adjustment
Sharp Object Hazard:
Use caution when making adjustments in this area.
Marker disks may be sharp.
Refer to Figure 33
To change angle of cut, and the width of the mark,
holding the disk assembly.
For a wider mark
, increase the angle of the
marker with respect to the tube
. For a narrower
, reduce the angle.
Note: Do not set a marker angle wider than needed to
make a useful mark. Excess angle increases wear
on all marker components.
Note: Direction of travel
tends to drive the disk angle to
Wide. If bolts are not tight enough, or loosen over
time, disk slips into the Wide mark configuration.
Refer to Figure 34
Applies to planters with serial numbers:
(YP3P425A s/n B1005M+)
(YP3P625A s/n B1007P+) (YP3P825A s/n B1008R+)
Current markers are equipped with an additional marker
disk adjust mount
which gives the marker added
capability of up/down direction of movement where
previously it only performed side to side movement.
Additionally, the markers are able to make a wider mark
in the field.
Sharp Overhead Object and Pinch/Crush Hazards:
Never allow anyone near the planter when folding or
unfolding the markers. Markers may fall quickly and
unexpectedly if the hydraulics fail. Anyone beneath may be
injured if hit by an unfolding marker, or caught in a folding
