Marker Operation
Great Plains does not manufacture markers for this
model implement. If you purchased markers, the marker
manufacturer has supplied operating instructions. Care-
fully read marker manufacturer’s instructions for safe
installation, operation and adjustment. You may also
need the following additional information.
Any markers are on a separate hydraulic circuit on the
implement. The leading air cart has provisions for this
circuit, but also shares the circuit for a cart function.
Markers use hydraulic receptacles and on the air
cart.
Refer to Figure 38
Markers (optional, third-party) share a circuit with the air
cart’s auger, controlled by a two-position selector valve
located at the front right corner of the front bulk hopper
on the cart. Handle settings:
Back: implement marker circuit enabled;
Forward: cart auger circuit enabled
At the implement, markers are typically controlled by a
local automatic sequence valve or solenoid valve (from a
cab switch).
