A self-propelling harvester thresher has two threshing mechanisms located one after the other in a direction which is transverse to a transporting direction and each having a threshing drum and a threshing basket. The threshing mechanism operate in accordance with the principle of a tangential flow and both drums of the thresing mechanisms rotate in the same direction. The threshing basket and the threshing drum of the first threshing mechanism and the threshing basket and the threshing drum of the second threshing mechanism are arranged with a gap relative to one another which gap is adjustable. The threshing drum of one of the threshing mechanisms which is the first threshing mechanism as considered in a working direction has a circumferential speed which is smaller than the circumferential speed of threshing drum of the other of the threshing mechanisms which is a second threshing mechanism as considered in the working direction.
