摘要：
An agricultural implement has a product supply chamber, and a pair oftransverselyextending product delivering booms, each with a plurality of conduits ofvarying lengthsterminating in product distributing nozzles. A fan supplies air to a mixingchamber which alsoreceives product from the supply chamber providing an air entrained flow ofproduct to eachconduit. A controller monitors product delivery and controls implementoperation. Each conduithas a pressure tap near the nozzle for providing the controller with apressure differentialindication. The controller initiates a corrective action modifying theoperation of the deliverysystem when a predetermined pressure differential threshold is exceeded. Thecorrective actionmay include an increased air flow volume, an additional burst of higherpressure air into theconduit, a temporary increase in air flow from the air flow source, or areduction in the rate ofproduct flow from the supply chamber.
