ABSTRACT:
An idler roll in a round baler has a number of belt-engaging portions spaced along its length, certain of which portions are of larger diameter than others so that the belts which wrap around the roll and are driven at a constant speed by other mechanism in the baler have a tendency to slip on some of the surfaces due to differences in peripheral speeds of such surfaces, which aids in maintaining the rolls polished and trash-free. A second idler roll has its own set of spaced, enlarged diameter portions, such portions on the second roll being in staggered relationship to those on the first roll so that the net differential in belt tension around the areas of large and small diameter is zero.
