Abstract: The invention concerns itself with a combine harvester including an axial thresher wherein are disposed a mowing device, an attached conveying system for the cut harvest product and a consecutive threshing drum assembly in the travel direction (45) of the combine harvester. The drum axis (43) of the threshing drum assembly (23, 25) is disposed opposite the travel direction (45) of the combine harvester in the horizontal line at an acute angle (.alpha.) so that the drum assembly is situated within the width of the vehicle. By this arrangement there results between the front side of the threshing drum assembly and the conveyor (9) a free space where it is possible to dispose an inserting device (23) that can transfer the harvest product into a tangential inlet (47) at the forward end of the threshing drum asssembly. In this manner there results an easy and smooth transfer of the flow of harvest product delivered by the conveyor into the threshing drum in the tangential direction desired.
