ABSTRACT:
A field chopper, having a chopper drum or reel rotatable on the chassis and a plurality of feed rollers for advancing the crop material to the chopper drum, is provided with a pair of arms flanking the drum and swingable about the axis thereof. The arms each carry a pivotal compensating bar, a pair of pressing rollers being journaled on these arms and being driven by gears meshing with a central pinion whose shaft forms the axis of one of the bars and is, in turn, driven by a transmission. The pressing roller proximal to the blade drum is received in notches in the compensating bars and is connected thereto so as to be easily releasable.
