In a combine harvester which conveys the straw which has been separated from grain to the rear outlet by means of a shaker, and wherein grain which is still present is fed to a sieve box, the straw is supplied to cutter means for comminuting purposes, said cutter means being detachably mounted at the rear outlet of the harvester-thresher. A straw accelerating drum with sieve means, which separate any still present residual grain, is mounted upstream of the bladed shaft which is mounted in said cutter means and is provided with blade comb, said shaft and comb being enclosed by a housing. Said sieve means simultaneously form the guide faces for supplying the straw to the straw accelerating drum, each sieve means having a trough portion associated therewith at its lower end for collecting the residual grain. An auger, which is mounted in said trough portion conveys the residual grain to a lateral winnowing grain elevator which re-supplies the residual grain to the sieve box via a chute.
