Abstract: A method and an apparatus for pivoting the dividers of an agricultural machine for the harvesting of row crops. A multiple-part attachment having feeder housings to receive the row crops is attached to the front of the agricultural machine. The multiple-part attachment has side frames that are pivotable from a working position to a non-working position. Outer row crop dividers are arranged on the side frames in such a way that when the side frames are pivoted, the outer row crop dividers move relative to the adjacent inner row crop dividers. The relative movement of the outer row crop dividers prevents them from colliding with each other when the side frames are in a non-working position and allows for maximum feeder housing width when the side frames are in a working position.
