ABSTRACT:
A baler adapted to be pulled along the ground to pick up a windrow of hay and roll the hay into a cylindrical bale of substantial size and weight. The bale is formed between a plurality of upper belts and an endless power-driven lower belt which is disposed in upper and lower runs between a forward drive roller and a rear tightener roller. Due to variations in the volume and density of the hay being introduced onto the lower belt, the same is subject to non-uniform loading transversely thereof. This uneven loading creates forces which tend to shift the belt away from the desired centered position in its path of movement. A system of rollers is disposed in rolling engagement with the underside of the lower run of the belt for maintaining the belt in centered relation even though the upper run is subjected to non-uniform loading. The system includes a pair of troughing rollers and a compensating roller successively engaged by the lower run in its path of movement toward the power-driven roller.
