ABSTRACT:
A large round baler includes a discharge or outlet gate mounted for swinging vertically about a horizontal transverse axis located approximately at the center of a baling chamber. In one of several variations, two hydraulic cylinders, that are arranged offset to each other, engage the outlet gate at various radial positions, so that both actuating devices cannot simultaneously reach a dead center or a blocking position.
