Marker Adjustments
There are five adjustments for markers:
•
Disk Angle
Even if your row spacing rarely changes, you may
need to adjust disk angle for soil conditions and
planting speed.
•
Marker Width
Once set for a specific row spacing, this only needs
periodic checking to ensure the clamp is secure.
See page 20.
•
Shear Bolt Replacement
If a marker hangs up on an obstruction, a bolt at the
fold is designed to fail. Positions are provided nearby
for storage of replacement shear bolts. See page 90.
•
Chain Length
Depending on marker width, you may want to adjust
the chain length to ensure the markers are off the
ground when the planter is raised. See page 90.
•
Marker Speed
Once initially set by your dealer, this rarely needs
modification. See page 91.
Marker Disk Adjustment
Sharp Object Hazard:
Marker disks may be sharp. Use caution when making
adjustments in this area.
To change angle of cut, and the width of the mark, loosen
1
/
2
inch bolts
holding disk assembly.
For a wider mark (W), increase the angle of the marker
with respect to the tube
. For a narrower mark (N),
reduce the angle.
Tighten bolts
.
The direction of travel (T) 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.
Crushing and Sharp Object Hazards:
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.
