  • Mounting assembly for a product distribution system of an air cart
    Patent number: 11395454
    Abstract: A product distribution system mounting assembly includes at least one bracket that is rigidly coupled to a frame of an air cart and at least one crossbar that supports at least one component of a product distribution system of the air cart. The at least one crossbar is slidingly coupled to the at least one bracket, thereby enabling the product distribution system of the air cart to move along a vertical axis relative to the at least one bracket and relative to the frame of the air cart as the air cart moves in a direction of travel through a field.
    Type: Grant

  • Method of using a particulate material delivery system to pneumatically dispense seed product
    Patent number: 9585305
    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.
