Abstract: A baler belt system for use primarily in round crop baling machines, includes an elongated elastomeric belt that is adapted for rolling engagement with one or more drive, idler, and tensioner rollers of the type normally used in a round crop baling machine. There are one or more sets of cleaning bars disposed on the inner and outer surfaces of the belt. Each set includes one or more flexible cleaning bars that deform during rolling contact with the various rollers. As the cleaning bars lose contact with the various rollers, they snap back to their original shapes, thereby releasing significant potential energy to loosen crop material that may have accumulated on the exterior surfaces of the rollers. In addition, the sets of cleaning bars function to urge an incoming stream of crop material into a tightly formed spiral without the necessity for an excessively aggressively textured belt surface.
