ABSTRACT:
To produce, monitor, and control a flow of air for a seed conveying system and a seed metering system, an air-assisted planting system includes an air handling system having a single air source and an air controller for maintaining a generally constant air pressure to the metering system. The air controller includes a plurality of sensors associated with and operable to monitor an air pressure through the metering system. Based on a sensed air pressure, a microprocessor of the air controller instructs the air handling system to selectively divert the flow of air to the metering system on an as-needed basis to maintain the generally constant air pressure.
