Abstract: An apparatus and method for metering and treating seed. The apparatus incorporates a belt conveyor or circular conveyor within a housing enabling a low-profile configuration, the conveyor having a plurality of cleats forming a series of separate voids for transporting determinable volumes of seed, and a seed treatment applicator adjacent the conveyor outlet for applying seed treatment to the seed. The apparatus and method enables the application of seed treatment based on a mass flow calculation derived from the measured volume flow through the apparatus.

Abstract: A hydraulic circuit having a boost pump in series with a primary (tractor) hydraulic source provides additional fluid power to operate an aircart fan in an air seeding system for which a tractor hydraulic system does not have enough fluid power capacity. The boost pump raises the pressure of the flow delivered to the fan motor up from that pressure delivered from the tractor to a higher pressure. Tractor pressure is supplied to the boost pump inlet, the boost pump is driven by ground engaging wheels of the aircart, and the resulting flow to the aircart fan motor is increased in pressure by the boost pump.

Abstract: An in-line seed treating unit is provided for an air seeding implement to coat seeds carried by a flow of air through a product distribution line before being planted into the ground. The in-line seed treating unit includes a cylindrical housing having input and outlet ends located at opposing axial ends of the cylindrical housing to provide a generally linear overall flow path for the seed entrained air flow through the product distribution line. A baffle formed as a spiral flighting with an open center portion is disposed within the cylindrical housing to induce the air flow and entrained seeds in a spiral flow path along the housing axis and, thereby pushing the entrained seeds outwardly toward the inner wall of the housing. The seed treatment material is injected through an injection port located a distance less than one flighting pitch of the baffle from the beginning of the flighting so that the seed treatment material is dispersed within the air flow to coat the entrained seeds.
