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.
