Abstract: An agricultural harvester includes a support frame and a hopper coupled to the support frame. The hopper is configured to store an agricultural product during a harvesting operation. An unloading system is coupled to the support frame. The unloading system is configured to transport agricultural product received from the hopper to an off-machine location. The unloading system includes a metering gate, a transfer conveyance, at least one sensor, and an electrical processing circuit. The metering gate is positioned near a bottom of the hopper and in communication with an interior of the hopper. The transfer conveyance has an inlet end and a discharge end. The inlet end is in communication with the metering gate. The at least one sensor provides an output signal representing an operating parameter associated with an unload rate of agricultural product through the transfer conveyance during an unloading operation. The electrical processing circuit is coupled to the metering gate and the at least one sensor.

Abstract: An agricultural harvester includes a first power unit and a second power unit. The first power unit is couplable with a first primary load, including a threshing system load. A first temperature sensor associated with the first power unit provides a first output signal. A second temperature sensor associated with the second power unit provides a second output signal. A first motor/generator is mechanically coupled with the first power unit, and a second motor/generator is mechanically coupled with the second power unit. The second motor/generator and the first motor/generator are electrically coupled together. At least one electrical processing circuit is Occupied with the first temperature sensor, second temperature sensor, first motor/generator and second motor/generator.

Abstract: An agricultural harvester rear axle arrangement for an agricultural harvester (10) having a body (12), the arrangement comprising left and right rear wheels (18, 20); means for supporting the wheels for rotation about a generally vertical steering axis (38, 40, 78, 94) and for supporting the wheels for extension and retraction from the body of the combine (26, 28, 30, 90); actuator means for steering the wheels (38, 40, 70, 72, 94) and for extending and retracting the wheels (34, 36, 70, 72); an electronic controller (50) coupled to the actuator means to steer, extend and retract the wheels.

Abstract: A new and improved conveyor feeder house chain slat having a unique shape and structure that provides sufficient structural rigidity to improve crop throughput while reducing clogging of crop material. The unique slat also provides additional support to the chain. Because the chain rides on the rear of the elongated section of the slat, the slat contacts the feed house, rather than the chain, reducing chain wear, overheating and lubricant evacuation. Because of the new slat configuration, the slats can be secured to the chain with removable securing means, enabling easier replacement of an individual slat if necessary.

Abstract: A rotor, in an agricultural harvester crop processing unit, comprising a drum to which crop processing elements for an infeed section and a threshing section are affixed. The drum comprises a rearward cylindrical portion and a forwardly extending frusto-conical portion. The frusto-conical portion is divided into an aft-region adjacent to the rearward cylindrical portion of the drum, and a fore-region. The infeed section has at least one infeed element located on the fore-region of the frusto-conical portion of the drum. The crop processing section has at least one crop processing element located on the aft-region of the frusto-conical portion of the drum.

Abstract: A system and method for limiting crop loss when harvesting on sloped or rolling ground by adjusting the chaffer and/or sieve, or longitudinal sections thereof, so as to overcompensate for the ground slope so that the chaffer and/or sieve sections are actually inclined away from horizontal opposite the direction of ground slope at a selected angle. Such overcompensation increases crop harvesting efficiencies over systems that simply work to level the chaffer and/or sieve sections, without the high expenses associated with a combine having a pivoting axle.

Abstract: A work vehicle having a fluent material spreader comprising two counter-rotating variable speed impellers adapted to receive and broadcast fluent material. A right-side impeller broadcasts out to a right-side material broadcast width, and left-side impeller broadcasts out to a left-side material broadcast width. Rotational speed of the right-side impeller is commanded to achieve a desired a right-side material broadcast width, and rotational speed of the left-side impeller is commanded to achieve a desired a left-side material broadcast width. Command of the right-side and left-side impellers is achieved either manually by and operator, or automatically by a control system based on sensor input.
