Abstract: A chopping assembly for a harvesting implement having a blade assembly, a housing, and a guide. The blade assembly is disposed within the housing and the guide directs cornstalks toward an input port on the housing. The blade assembly not only cuts the cornstalk from its root but also chops the stalk into stover. A fluid dynamic force is created by the blade assembly to direct the stover with the aid of the housing to an output port.

Abstract: A combine harvester having a frame and a crop harvesting header supported by the frame to gather crop material. A threshing and separating mechanism connected to the frame that receives the crop material from the header to thresh and separate the grain. A shoe assembly positioned beneath the threshing and separating mechanism to receive the threshed grain connected to a drive that affects fore-and-aft reciprocating movement of the shoe assembly which conveys grain rearward. A flexible seal attached to the underside of the shoe assembly across the width of the shoe to obstruct air from flowing under the shoe assembly.

Abstract: A sealing system for the shoe in a combine harvester is disclosed wherein the separate flow areas in the shoe are sealed from one another. The sealing system discourages air from traveling through the components of the shoe other than the sieve system, thereby providing flow of air to the sieves. The positive differential and the containment of air in the shoe are accomplished by providing one or more seals between the moving shoe components and the stationary frame components. In those combines including self-leveling shoe assemblies, the distance between the shoe assembly rolls to maintain level operation. Various embodiment of this invention provide for sealing this change in the dimensions as the shoe moves.

Abstract: In a combine having a header to cut crop material and an elevator to deliver the cut crop material to auger means in an undershot manner for feeding the same to threshing rotors of an axial flow combine, there is provided an improved transition or feed plate between the upper end of the elevator and the forward end of the rotor means to postpone or delay the discharge of crop material by the rear discharging portion of the elevator until leading portions of the discharging crop material are at least partially engaged by the auger means whereby more positive control is maintained over the transfer of crop material from the elevator to the auger feeding means.
