Abstract
A baler adapted to be pulled behind and powered by a PTO-equipped tractor for picking up a windrow of hay and rolling the hay into a cylindrical bale of substantial size and weight. The baler includes a bale-supporting lower belt and a plurality of upper bale-forming belts superposed over the lower belt, together defining the upper and lower parameters of bale-forming zone. The upper belts are driven by a pair of drive rollers disposed above the forward portion of the lower belt. A press roller is disposed closely adjacent to the forward portion of the lower belt and together with one of the drive rollers defines the forward parameter of the bale-forming zone. A pickup delivers the windrwed hay beneath the press roller and into the zone. The baler includes a gate structure above the lower belt pivotable rearwardly as the bale size increases. Journalled on the lower end of the gate is a roller engageable with the upper belts and which defines a rear parameter of the bale-forming zone. The roller is pivotally mounted on the gate so as to be movable in a straight line path closed) adjacent and parallel to the lower belt as the gate pivots rearwardly. A compact cost-efficient drive system powers the pickup, lower belt, upper belt and the press roller.
