Abstract: An agricultural implement including a toolbar, a plurality of row units connected to the toolbar, and a pneumatic seeding system. The pneumatic seeding system includes at least one storage tank configured for storing the particulate matter, a plurality of fluid lines fluidly interconnecting the at least one storage tank with each row unit of the plurality of row units, a fan fluidly connected to the at least one storage tank and to the plurality of fluid lines, and at least one pinch valve fluidly coupled to at least one fluid line of the plurality of fluid lines for adjustably balancing a respective airstream within the at least one fluid line of the plurality of fluid lines.

Abstract: A pneumatic distribution system for an agricultural implement, including a plurality of fluid lines including a primary fluid line and at least two secondary fluid lines, and at least one header fluidly coupling the primary fluid line with the at least two secondary fluid lines. The at least one header includes a header body having a fluid inlet fluidly coupled to the primary fluid line and at least two fluid outlets fluidly coupled to the at least two secondary fluid lines, a top cover connected to the header body, an insert located beneath the top cover and associated with the fluid passageway, and at least one actuator operably coupled with the insert and configured for moving the insert to control the airstream.

Abstract: A method of monitoring a mass flow rate of product being applied with an agricultural implement includes the steps of: calibrating a pressure drop across a known distance in an air line at a number of air flow rates; metering a product at a desired application rate into the air line at a selected one of the air flow rates; establishing a pressure drop across the known distance at the selected air flow rate, while the product is being metered at the desired application rate; calculating a value of K1 dependent on the established pressure drop; estimating a mass flow rate of the product being applied, using the mathematical expression: log ?=?(1+?)·log Fr+K1 where ? (mass loading ratio); Fr (Froude number); ?=calibration variable; and K1=constant for a given product being applied at a given mass flow rate.
