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.

A seed treating device is mounted on a seeding implement to treat untreated seeds carried by the implement with inoculants or other treating material before the seeds are planted into the ground. The implement conveys seeds in a flow of air carried by conduits to entrain the seeds within the air flow. The seed treating unit is placed on the implement remote from the storage tank for the seeds to receive airborne seeds from an inlet tube, treat the seeds with a coating material, and discharge the seeds through an outlet tube to planting mechanisms. The seed treating unit includes a conical mixing chamber to induce the air/seed flow into a whirling motion where the coating material is introduced for an even coating of the individual seed particles. The inlet line is oriented generally tangential to the circular mixing chamber, while the outlet line is generally perpendicular to the inlet line and is centrally connected to the main axis of the mixing chamber.

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. Preferably, the in-line seed treating unit is formed as a modular component that can be inserted into any selected product distribution line on the air seeding implement.
