Abstract
A baling chamber for a large round baler includes a discharge gate having opposite side walls which meet respective side walls of the main frame along a line of separation that inclines downwardly and to the rear from top to bottom. The bottom of the baling chamber is defined in part by a bottom conveyor which slopes downward to the rear from a front end which delimits a lower side of an inlet through which crop is fed into the baling chamber. The discharge gate carries a lower front roll that supports an endless tension element arrangement and that is itself supported on a tensioning arm arrangement that pivoted to the discharge gate for movement against the resistance of a yieldable spring arrangement so as to permit the lower front roll to move rearwardly from a first position adjacent the inlet, which it occupies at the beginning of bale formation, as the bale grows.
