Abstract
A particulate material delivery system is provided that allows for variable rate sectional control while delivering particulate material to an agricultural field. The system may include an air cart and a drill that are towable behind a tractor and that includes a metering system receiving product from the air cart and delivering the product to the drill for distribution to the ground, such as an agricultural field. The metering system includes multiple metering units that receive separate portions of the product from the air cart. Multiple prime movers drive the multiple metering units. A controller is connected to and individually controls the multiple prime movers such that distribution rates of the multiple metering units can be varied independently of each other.
