ABSTRACT:
A transverse belt guide roll of the baler has its main cylindrical body portion provided with opposite end extremities which are spaced inwardly from the opposite sidewalls of the baler. Reduced diameter stub shafts project outwardly beyond the end extremities and into bearings supported by the sidewalls while the endmost belts along the roll have marginal edge portions which overhang the end extremities of the roll body to thereby eliminate a pinch point for loose residue between the belt edges and the surface of the roll body. Special annular components surrounding the otherwise exposed portions of the shaft ends serve as a shield to prevent the ingress of loose residue into the stub shafts for migration to the bearing assemblies. An alternative embodiment has the overhanging belt margins on one of the idler rolls carried by a vertically swingable belt control arm of the baler.
