Abstract
Abstract A tractor mounted forage harvester includes a transverse hitch bar or frame, a crop processing unit mounted on the frame and a windrow pickup unit releasably attached to the front of the crop processing unit during the field operating mode. The total width of the harvester is reduced when converted to the transport mode by uncoupling the pickup unit, moving the same to the rear of the processing unit and the tractor, and coupling it to the frame via a subframe mounted thereon such that the major axis of the pickup unit is maintained in the same transverse relationship to the direction of movement of the forage harvester as when the unit is attached to the front of the processing unit.
