Abstract: In an agricultural combine including a rotor of a threshing system, a concave positioned beneath the rotor, a rotor cage positioned above the rotor, a drive controllably operable for rotating the rotor in opposite first and second rotational directions, a control in operative control of the drive, and a sensor for sensing information representative of load conditions opposing rotation of the rotor, a method for deslugging the threshing system of the agricultural combine includes the steps of (i) sensing information representative of load conditions opposing rotation of the rotor above a pre-determined threshold, which indicates a slugging condition; (ii) activating an actuator, which adjusts one or more components to move from an initial position to a deslugging position; (iii) rotating the rotor; and (iv) sensing information representative of load conditions opposing rotation to determine whether the slugging condition still exists.

Abstract: An agricultural harvester includes a threshing system having a rotor, a rotor cage surrounding the rotor and including a concave, and a transition cone defining an infeed to the rotor cage. The transition cone has a conical inner surface extending in an axial direction between an upstream end and a downstream end of the cone. A vane is mounted to the conical inner surface of the transition cone. The vane protrudes radially from the conical inner surface, and extends along an axial direction between the upstream end and the downstream end. The vane has a body extending along an axis and a cross-sectional shape that is not constant along the axis.

Abstract: An embodiment includes a combine having a header with a motor driving a blade for harvesting crop, a power receiving connector connected to the motor, where the power receiving connector supplies power to drive the motor, and a mechanical connector. The combine also includes a feeder housing with an opening for receiving the harvested crop from the header, a power supplying connector connected to a power plant of the combine, and a mechanical actuator. A controller controls the combine by attaching the header to the feeder housing by lifting the header such that the power receiving connector and the power supplying connector are automatically mated, and such that the mechanical actuator and the mechanical connector are mated, and controlling the power plant to generate and supply electrical power or hydraulic power to the power supply connector, which is supplied to the motor of the header via the power receiving connector.

Abstract: A threshing system for a combine harvester includes a support bracket that is configured to be attached to a threshing rotor cylinder of the threshing system and a rasp bar that is configured to be mounted to the support bracket. A channel is formed in one of the rasp bar and the support bracket for receiving a surface of the other of the rasp bar and the support bracket, wherein engagement between the channel and the surface limits movement of the rasp bar on the support bracket.

Abstract: A combine harvester includes a header assembly configured for collecting a crop, a threshing assembly coupled to the header assembly and configured for separating grains of the crop from material other than grain, and a cleaning assembly positioned in association with the threshing assembly and configured for separating the grains from chaff. The cleaning assembly includes a fan assembly having a fan housing with a fan output duct and a fan mounted to the fan housing, and one or more cleaning sieves. The fan assembly is configured to blow air across the one or more cleaning sieves via the fan output duct. The fan output duct includes at least one segmented air deflector.

Abstract: A combine harvester includes one or more threshing rotors (5) mounted in the harvester, a grain pan (7) and a set of sieves (8), and a drive mechanism configured to drive a longitudinal reciprocating motion of the grain pan (7) and superimpose a lateral reciprocating motion component on the longitudinal reciprocating motion.
