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.

Bale density structure for cylindrical balers

A hay baler for picking up windrowed hay, forming a cylindrical bale, feeding twine onto the bale during the latter stage of bale formation, and cutting the twine after the bale is wrapped. The hay is picked up and fed rearwardly under a press roller onto an endless belt. A plurality of oppositely running belts is disposed above the lower belt defining a bale-forming zone there-between. The twine extends from a source of supply on the baler through an elongated twine feed tube. The tube is pivotally mounted such that its dispensing end is swingable through an arc above the incoming hay to and from a home position for feeding twine into the hay and around the bale. As the tube is swung back toward the home position a twine hook is actuated through an interconnected linkage and the twine is pulled downwardly onto a fixed knife which severs the twine.
