Adjustments
Cart Weight Transfer
Some of the cart weight can be transferred to the
mainframe by retraction of the lift-assist cylinders, with a
weight-transfer pin in place. This operating mode is
compatible with wing-lock, wing-flex and hydraulic
down-pressure planters.
1. Disconnect the 3-point top link.
Refer to Figure 75
2. Install the lift-assist weight-transfer pins
. The pins
are stored in a plate behind the cart parallel arm
pivot weldment. Install them in the large holes at the
bottom of the rod-end lug in the frame-to-cart parallel
arms.
3. Remove the lift-assist shear bolts from the small
holes
below the lift-assist rod-end lug upper pivot
pins. Store the bolts in the plates behind the cart
parallel arm pivot weldments.
4. Fully retract the lift-assist cylinders when lowering
the planter in the field.

Marker Disk Adjustment
Sharp Object Hazard:
Use caution when making adjustments in this area.
Marker disks may be sharp.
Refer to Figure 76
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
.
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.

Sharp Overhead Object and Pinch/Shear 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
marker.
