Patent number: 4564025Abstract: A self-propelled harvester thresher has a housing, and at least one axial threshing and separating device with a rotatable drum and a casing surrounding the latter, wherein the axial threshing and separating device is turnable between a working position in which it extends transverse to a transporting direction of the harvester thresher, and a transporting position in which it does not exceed permissible street width.Type: GrantFiled: March 5, 1984Date of Patent: January 14, 1986Assignee: Claas OHGInventor: Johannes Dammann
-
Patent number: 4526181Abstract: 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.Type: GrantFiled: October 18, 1983Date of Patent: July 2, 1985Assignee: Claas OhgInventors: Franz Heidjann, Johannes Dammann
