ABSTRACT:
A self-propelling harvester thresher has a cutting and transporting unit, a threshing unit having a threshing basket and a threshing drum, a transferring drum and a separating unit having a separating rotor and a separating housing with a drawing-in opening. The threshing drum has a plurality of threshing segments arranged on its periphery and offset relative to one another. The transferring drum is provided with a plurality of drivers arranged on a periphery of the transferring drum and offset relative to one another similarly to the threshing segments of the threshing drum. The drivers are formed as individual point-like elements which are spaced from one another in an axial direction and in a circumferential direction of the transferring drum and engage in a product accumulation in a point-like manner so as to loosen and to spread the product accumulation and transport parts of the product accumulation in a longitudinal direction of the harvester thresher while other parts of the material accumulation remain behind.
