Abstract
A combine comprises a separating assembly defining a first crop residue stream and a cleaning assembly having a second crop residue stream. The first crop residue stream is directed to a straw chopper in a chopping mode and around the straw chopper in a straw swath disposition mode. The second crop residue stream is directed to the straw chopper in both modes. A conveying device conveys the second crop residue stream to the straw chopper. The conveying device feeds the second crop stream mechanically and separates it in two partial streams which are fed into the straw chopper. The conveying device has a transversely extending rotational axis parallel to the rotational axis of the straw chopper.
