Abstract

In a chopper for comminuting stalk-shaped harvested crops, in particular maize, to improve the throughput it is proposed that the cutting drum (10), the press rollers (7) and the post-accelerator rotor (6) have the same width. Preferably, the post-accelerator rotor (6) is arranged directly above the press rollers (7) and, to be precise, in particular on the side on which it can have the same direction of rotation as the cutting drum (10).
