Abstract
A differential pressure sensor measures the vacuum in a material conveying duct relative to atmospheric pressure or to a positive pressure farther upstream in the duct on an agricultural harvester. The output from this sensor is monitored electronically, and the resulting output is used to optimize harvester speed. In one embodiment, a processor monitor output is used in conjunction with the pressure sensor output to control ground speed. Processor speed or loading and air duct pressure are monitored to determine which area of the machine is the limiting factor and to adjust the harvester speed accordingly.
