Abstract

A crop baler comprises a frame, a pressing chamber for crop, into which a stuffer can be introduced in order to compress the crop into a bale, a drive for producing a reciprocating movement of the stuffer, and a countermass coupled to the drive and configured to move in a counteracting direction to the movement of the stuffer, the countermass at least approximately compensates movement of the frame induced by the reciprocating mass of the stuffer and the drive unit thereof due to inertia. Alternatively or additionally, a flywheel mass of the drive can have a variable moment of inertia to similarly compensate movement of the frame induced by the reciprocating mass of the stuffer.
