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.
