Abstract: A distributing device for chaff choppers for attachment to mowing-threshing machines has a top cover plate, beneath which right and left groups of baffles are arranged next to one another, preferably at right angles to the cover plate. The baffles are pivotably supported around axles at their ends facing the chopper and spaced therefrom, while being rigidly connected by guide bolts penetrating guide slots in the cover plate or in the machine casing. A set bar is associated with each group of baffles. The baffles are connected with each other by the guide bolts which are rotatable in fixed bearings and by two guide rails, and, at their ends facing the chopper, rotatably and displaceably arranged in points on the cover plate. The guide slots of each group extend displaced relative to each other in a transverse direction, substantially parallel to each other and to a line through the axles.

Abstract: 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.
