Marker Unfolding
Electrocution Hazard:
Beware of overhead electrical lines. If the markers contact
lines, the tractor, raised Planter and any cart can become
“hot” with no indication. A person standing on the ground and
touching equipment can complete the circuit. Serious injury or
death is likely. At higher voltages electrocution can occur
without direct contact.
If your planter Planter has markers, unfolding of the
markers is performed only after unfolding the wings.
The Marker/Aux valve on the left wing must be set to
“Marker”. See “
Before operating markers, make sure cylinders are
properly bled. See “
This section presumes correct marker length for your
pass spacing. If this has not been set, or needs to be
changed, see “
Dual markers are equipped with an automatic sequence
valve that controls which side activates, as well as
marker deployment.
Folding speed of dual markers is adjusted via set
screws on the sequence valve body. Excessive folding
speed may damage markers. See “
Marker Unfold (one side)
Refer to Figure 59 and Figure 60 (depicting identical
operation on model YP40)
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.

Overhead Crushing and Sharp Object Hazard:
Do not allow anyone to stand near or beyond the end of the
wings during marker operations. Marker arms are heavy and
marker discs may be sharp. Serious injury or death is possible.
