  • Patent number: 10448574
    Abstract: A compression roll housing for an agricultural machine, having a side panel provided with at least one elongated aperture for receiving a shaft of a compression roll and allowing movement of the shaft within the aperture. The housing is provided with a cover plate which rotates about an axis parallel to the shaft and is provided with an indentation to partially surround the shaft. Movement of the shaft, such as along a longitudinal axis of the aperture, causes the plate to rotate to provide a cover across the aperture to prevent the escape of any material from the housing.
    Type: Grant

  • Patent number: 9743588
    Abstract: A drive arrangement for a harvesting header of a harvesting machine having a running gear on which a feeder housing is mounted. A front side of the feeder housing has a header mount that moves relative to the feeder housing and on which the harvesting header is detachably fastened. An automated coupling mechanism is provided to link a driven shaft from the harvesting machine to a drive shaft of the harvesting header as the header is connected to the harvesting machine. The drive connector connected with the header mount is movable relative thereto during the attachment of the harvesting header to axially align the driven shaft and drive shaft as the harvesting header approaches the feeder housing during the attachment to accommodate differing header drive shaft orientations.
