Abstract: A mobile harvester unit provided with a row crop attachment having a plurality of laterally spaced generally fore-and-aft dividers defining one or more elongated passageways for accommodating rows of crop material. Crop severing means are disposed along each passageway for cutting crop being guided rearwardly during operation. Feeder assemblies, disposed in longitudinal alignment with the dividers, comprise gathering fingers extending from at least three rigid bars adjacent the passageways. The bars, mounted at equal intervals on rigid rotatable elements, are rotatably driven to impart intermittent rearward motion of the fingers in the passageway to urge crop toward the harvesting unit.

Abstract: The invention provides a low profile, compact row crop attachment which eliminates the use of crop conveyors in the form of chains with crop-engaging extensions attached thereto, such conveyors being subject to fast wear and being relatively expensive to replace. The chain type conveyors are replaced by a plurality of pairs of rotary means provided on opposite sides of an associated stalkway defined by a pair of spaced apart members. Conveyor means extend from the rotary means from outside into the associated stalkway so as, in operation, to convey crop along that stalkway, the conveyor means of each pair of rotary means having overlapping paths.

Abstract: The device comprises at least one gatherer having two dividers and two advancing devices in the dividers for advancing severed stalks which have been severed by a cutting mechanism. Each advancing device comprises a front shaft and a rear shaft, the front shafts being parallel and upwardly and forwardly inclined and each carrying a rotary cutter adjacent the lower end of the shaft, a chain sprocket wheel and a rotary member fixed to the shaft adjacent the upper end of the shaft. An endless chain of each advancing device extends around the corresponding sprocket wheel. The rotary cutters are contained in the same plane and rotate in opposite directions. The rotary members co-operate with each other for seizing successive stalks before the stalks are severed and directing the stalks in a passageway defined by the dividers.
