  • Patent number: 4526181
    Abstract: A self-propelled harvester thresher operating in accordance with an axial threshing principle has an axial threshing and separating mechanism located between a cutting mechanism trough and an inclined conveyor, and an introducing drum for introducing the product cut by the cutting mechanism trough into the axial threshing and separating mechanism and formed as an exchangeable threshing drum corresponding to a product to be threshed, so that a threshing and separating element of the threshing and separating mechanism thus performs only post threshing and separating functions.
