Adjustments
Marker Adjustments
There are three adjustments and three
setup/maintenance items for markers:
•
Disk Angle (following)
Even if your row spacing rarely changes, you may
need to adjust disk angle for soil conditions and
planting speed.
•
Shear Bolt Replacement (page 103)
If a marker hangs up on an obstruction, a bolt at the
fold is designed to fail.
•
Marker Cylinder Bleed (page 104)
Once set for a specific row spacing, this only needs
periodic checking to ensure the clamp is secure.
•
Marker Chain Length (page 59)
•
Marker Extension (page 60)
Once set for a specific row spacing, this only needs
periodic checking to ensure the clamp is secure.
•
Marker Speed (page 122)
Once initially set by your dealer, this rarely needs
modification.
Marker Disk Adjustment
Sharp Object Hazard:
Use caution when making adjustments in this area. Marker
disks may be sharp.
1.
To change angle of cut, and the width of the mark,
loosen
1
2
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 needed 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.
3.
Resume planting.
A small varying population deviation between rows is
normal. If a row is consistently running lower or
higher than the other rows, it could indicate a meter
or seed sensor problem that needs attention.
“
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 drill when folding or
unfolding the markers.
