Abstract

See full text

An apparatus for merging a pair of windows into a single window for subsequent processing by a forage harvester, square baler or the like. The apparatus includes a main frame, a rotary pickup head for picking up the first windrow, a cross conveyor mounted on the main frame and disposed rearwardly of the pickup head for transporting the first windrow transversely between a windrow receiving end and a windrow discharge end, a hydraulic drive circuit including a cross conveyor drive motor and a pickup drive motor, a speed control mechanism for controlling the speed of the cross conveyor independently of the speed of the pickup head so that conveyor belt speed may be adjusted depending upon the distances between windrows to either discharge or throw the first windrow a further distance or a shorter distance so as to be combined with a second adjacent windrow. There is also disclosed a quick attachment assembly for pivotally and releasably attaching the main frame to a tractor.
