Markers use hydraulic receptacles
and on the air
cart. Any markers are on a separate hydraulic circuit on
the implement.
Markers share a circuit with the air cart’s auger,
controlled by a two-position selector valve located at:
ADC2350: front right corner of the front bulk hopper
ADC1150/2220: outside of left tongue
Handle
settings:
Implement marker circuit enabled (auger off);
Cart auger circuit enabled (markers off)
At the implement, markers are typically controlled by a
local automatic sequence valve or solenoid valve (from a
cab switch).
