  • Patent number: 7462101
    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.

  • Patent number: 7059960
    Abstract: A composite threshing element, for a rotor in an agricultural harvester crop processing unit, comprising a hollow support structure with at least one outwardly extending crop engaging portion, and a forwardly extending infeed element attachment feature. The rotor comprises a drum to which crop processing elements for an infeed section and a threshing section are affixed. The threshing element is bolted to a frusto-conical portion of the rotor drum, with a portion of an infeed element bolting to the infeed element attachment feature.

  • Patent number: 6397571
    Abstract: The combine of the present invention is provided with an internal combustion engine. An electronic engine controller is used to monitor and control the operation of the engine. The electronic engine controller stores at least two power curves for controlling the engine. The first power curve has a higher horsepower output than the second power curve. A harvesting assembly detector signals the electronic engine controller with a corn head signal if a corn head is mounted to the combine, or a grain platform signal if a grain platform is mounted to the combine. If a corn head is mounted to the combine the electronic engine controller derates the engine and works on the second power curve. If the electronic engine controller receives a grain platform signal, the electronic engine controller works on the higher horsepower first power curve.
