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.

In a harvester-thresher including a threshing drum or including a shaker which conveys straw which has been separated from grain to a rear outlet, and including a cutter with a bladed shaft which cutter is detachably mounted at the outlet of the harvester-thresher downstream of said drum or shaker with respect to the flow of harvested material, the improvement comprising at least one straw accelerating drum mounted immediately upstream and proximate of the bladed shaft and having sieve means which are spaced from said drum and permit falling residual grain to pass therethrough.
