A combine harvester having a rotary separating mechanism operable to separate grain from crop material and to propel straw in a desired path for discharge from the machine through a discharge opening is disclosed wherein a rotary straw discharge assist beater is located below said desired path and between the separating mechanism and the discharge opening to assist in the propelling of straw in a rearward direction. The assist beater prevents straw from accumulating on the rear wheel axle of the combine and helps feed straw into a rearwardly located straw chopper. For combines having a pair of transversely spaced discharge openings, a pair of assist beaters can be provided.

Discharge assist means for combine harvesters

In a combine harvesting machine comprising a plurality of interconnected sub-assemblies, there is provided the apparatus and the method for utilizing an entirely separate, self-contained, and self-supporting straw walker sub-assembly that may be mounted to a mobile chassis during the production line assembly.

Combine harvester

The invention relates to combine harvesters having stone traps for collecting stones and other foreign objects before they reach the threshing means of the harvesters and enabling the trapped stones to be easily removed from the harvesters. A combine harvester according to the present invention comprises a crop elevator having a rear discharge end, threshing means including a rotatable cylinder and a cooperable concave forming a nip therebetween; the nip being spaced rearwardly of the discharge end to define an opening directed downwardly to a stone trap having a lower wall extending downwardly and forwardly to a forward edge; the stone trap having an outlet closable by a door which is pivotally mounted on the forward edge and which, in a closed position thereof, seals against an underside surface of the crop elevator, the crop elevator being capable of adopting an operative position in which the forward edge of the stone trap is disposed beneath the elevator and in which the stone trap extends forwardly of and beneath the discharge end of the elevator.
