Abstract
A large round baler is equipped with a chassis, including an outer pair of fixed side walls, that extend rearwardly beyond a pair of inner side walls which form opposite sides of a baling chamber. In an upper region of the baler, belts or the like are supported by a plurality of fixed rotary bodies extending either between the inner or the outer side walls and a movable rotary body carried at the end of a pivotally mounted tension arm, to form a large take-up loop that becomes smaller as a run of the belts expands during growth of the bale being formed. The run of belts, which is looped about the bale being formed, is conducted over rollers carried by a vertically pivoted frame, such that when the frame is swung between a lower extreme position, which it occupies during formation of a bale to a raised position, the formed bale is deposited on the ground.
