  • Patent number: 7223167
    Abstract: An anti-wind wiper including an extension adjustably mountable in a desired spaced relation and angular orientation relative to a leading edge of a flight of a front rotor inlet section of a combine, for interaction with the flight during rotation of the rotor, for directing and guiding crop material, particularly long strand-like elements of crop material, away from a shaft and bearing supporting the inlet section.

  • Patent number: 7186177
    Abstract: A threshing front rotor inlet section and front bearing housing shroud assembly for an agricultural combine. The front rotor inlet section includes a center body or plate having a radial outer circumferential periphery and a substantially annular protuberance extending forwardly therefrom concentric with a rotational axis thereof. The protuberance has at least one slot extending radially therethrough defined by one or more edges and/or surfaces which face in the rotational direction and are raked back in the radial outward direction, for pushing crop material, radially outwardly for conveyance rearwardly by impeller augers or flights of the rotor. Other surfaces can also be provided around the outer periphery for pushing longer plant material away from spaces between the inlet section and bearing housing and shroud.

  • Patent number: 6053811
    Abstract: An apparatus for use in combination with a combine for sensing the volume of tailings exhausted from a cleaning section of the combine and for providing a visual indication to the operator of the effectiveness of combine operation. The combine includes a mobile frame or chassis having an operator compartment arranged toward a forward end thereof. A threshing section of the combine separates grain from crop material delivered thereto. A cleaning section of the combine functions to remove chaff and tailings from the materials received from the threshing section. A tailings section of the combine is arranged to receive incompletely threshed and separated tailings from the cleaning section. The tailings section comprises a tailings conveyor for forcibly moving tailings toward an elevator that moves the tailings to one of the other sections on the combine for recycling.
