YP2425A Table of Contents Index Operating Instructions
Marker Unfold (one side)
Refer to Figure 42 and Figure 44
1. If the Auxiliary Hydraulic circuit has been used
recently, confirm that the manual Marker/Aux valve
on the left wing is set to “Marker”.
2. On the DICKEY-john
®
Clutch Folding Module (CFM),
set “Marker/Fold” switch to Marker (up). The LED
above the switch illuminates steadily for normal
operation.
3. Move tractor hydraulic control (lever or switch) for
the marker circuit to Extend. Hold until marker is
completely unfolded. Do not leave tractor control in
detent.
4. If the marker side operating is not the desired side,
let it unfold part way, and move the tractor’s circuit
control to “Retract”. When the marker is folded,
move the circuit control to Extend to activate the
other side.
On the CFM, leave the “Marker/Fold” switch in “Marker”
during normal field operations.
Row Marker Operation
To alternate which side is marked:
1. Move the tractor’s circuit control to fold marker. Hold
until marker is folded.
2. Reverse the tractor’s circuit control. Hold until the
new side’s marker is fully unfolded.
3. Return tractor control to neutral.
Folding the Markers
If your planter has markers, they must be folded and
secured before folding the wings.
1. Move the tractor’s circuit control to Retract. Hold until
marker is folded.
2. Set circuit control to neutral.
Unusual Marker Operations
Both Sides Unfolded
With both markers in their cradles:
1. Unfold either side, and when completely deployed:
2. Move lever/switch to Retract momentarily, and return
to Extend to deploy other side.

Machine Damage Risk:
If the marker gauge wheel (at the hinge) is not routinely in
ground contact, machine damage can occur.
Verify that the planter is fully lowered, the marker is fully
extended, and the marker chain has adequate slack. If only one
side is out of contact, check for debris in the outer hinge.
See “ Marker Gauge Wheel Adjustment ” on page 62.
