A cleaning system of a combine harvester includes a fan, a first valve member positioned within a first duct of the fan for throttling the flow of air through the first duct, a second valve member positioned within the second duct of the fan for throttling the flow of air through the second duct, a first actuator for adjusting a position of the first valve member, a second actuator for adjusting a position of the second valve member, first and second sensors for sensing air pressure at first and second sieves, and a controller. The controller is configured to receive the sensed air pressures from the sensors, compare the sensed air pressures with either each other or threshold values, and transmit instructions to one or both of the actuators to adjust the positions of one or both of the valve members.

Closed loop combine cleaning fan control

An improved cutter assembly for use with a header of an agricultural harvester is provided. The assembly includes a pair of oppositely directed knife blades or cutter bars and a center knife drive. A crank shaft drives both knife blades in linear reciprocating paths with no fore and aft movement. As a consequence, harmful fore and aft vibration is eliminated. The assembly is simple and durable in design, less susceptible to vibration-induced wear and tear, and comparatively simple to manufacture and repair.

Cutter assembly for an agricultural harvester

An agricultural harvester includes a header with an infeed assembly including a driving element configured to rotate; a hollow tube rotationally coupled to the driving element and having a plurality of openings formed therein; and at least one finger unit rotatably held within the hollow tube. Each finger unit includes: a finger hub having at least one pivoting aperture formed therein and at least one driving aperture formed therein; a pivoting finger pivotally held within the at least one pivoting aperture and configured to at least partially extend out of one of the openings of the hollow tube during rotation; and a driving finger fixedly held within the at least one driving aperture and configured to at least partially extend into one of the openings of the hollow tube to rotate the finger unit by the hollow tube.
