Abstract
A combine comprising an axial separator having an outlet for directing crop material to a rotatively driven discharge beater. The discharge beater is adjacent to the outlet of the axial separator and is aligned to propel crop material discharged from the axial separator into a straw chopper. There is a straw guiding device between the outlet of the discharge beater and the inlet to the straw chopper. The straw guiding device comprises at least one flap, which is supported so that it can pivot at its end facing the discharge beater and which can pivot between a first chopping position, in which it guides the crop material into the straw chopper, and a second position for laying long straw, in which it guides the crop material onto the ground.
