Abstract: A cutting mechanism for the harvesting of whole plants can include a number of mowing elements, which include a lower cutting disk and conveyor rotors located above, two transverse conveyors located in the back, and a delivery conveyor. The cutting disks of the mowing elements work together with a frame-affixed counter-blade and can be driven together with the corresponding conveyor rotors by a shaft. The shafts are driven by a gear arrangement that extends, on the front side, over the width of the cutting mechanism. The frame of the cutting mechanism can include a middle part and lateral parts that are placed so they can swivel, on the middle part, between a horizontal operating position and a raised transporting position.
