Abstract

The invention concerns a combine (10) with a chassis (12) that can be moved across a field in the forward operating direction, a harvested crop processing arrangement (26) with an outlet (62) for straw and a straw chopper (60) with an inlet for straw (58). A rotating conveyor drum (68) is attached downstream of the outlet (62) of the harvested crop processing arrangement (26) and upstream of the inlet (58) of the straw chopper (60) that rotates in a first direction of rotation in the swath deposit operating mode and that conveys the straw received from the harvested crop processing arrangement (26) past the straw chopper (60) to the ground, and conveys it in the chopper operating mode in the second direction of rotation into the inlet (58) of the straw chopper (60).
