Baling chamber arrangement of a large round baler designed for quick bale discharge

In a large round baler having a frame supported on ground-engaging wheels and including a first pair of transversely spaced side walls, a discharge gate including a second pair of transversely spaced side walls mounted to an upper rear location of the first pair of side walls for pivoting between a lowered operating position, wherein respective facing edges of the first and second pairs of side walls meet along a line of separation, and a raised discharge position, and a bale-forming chamber being defined in part by said first and second pairs of side walls and by a plurality of transverse bale chamber forming rolls extending between and supported by said first and second pairs of side walls, with the bale-forming chamber having a crop-receiving inlet defined at a lower front location thereof, the improvement comprising:

• one of said bale chamber forming rolls being a lower front roll carried by said discharge gate;
• and mounting structure coupled between said lower front roll and said discharge gate for guiding said lower front bale chamber forming roll from a first position close to said inlet, which it occupies when formation of a bale is just starting, to the rear as the bale grows in size, and for positioning said lower front roll such that it remains in contact with a lower rear location of a periphery of said bale during formation of said bale;
• and a yieldable tensioning device resisting rearward movement of said lower front roll.
