Abstract

A combine (10) comprises a crop processing device (26) having a straw outlet (62), a beater (64) assigned to the straw outlet (62) of the crop processing device (26) and a straw chopper (60). An overshot drum conveyor (68) follows the beater (64). A single, pivotable flap (80) is located downstream the drum conveyor (68) and movable between a chopping position in which it deflects the straw downward into the straw chopper (60) and a swath laying position in which it lets the straw pass to a slope (88) behind the straw chopper (60). The flap (80) is pivoted at its forward end adjacent and above the drum conveyor (68) and has a shape matching to the circumference of the drum conveyor (68).
