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 in a zone defined between a lower belt conveyor and a plurality of endless belts disposed in transversely spaced relation above the lower belt. The upper belts are disposed to encompass a substantial portion of the periphery of the bale being formed to compress the same to the desired density. A bale tightener assembly is pivotally mounted on the baler and includes rollers in engagement with the upper belts. The tightener assembly is biased against the belts by tension springs arranged and functional in a novel manner.
