A stalk shredder (132) configured to be attached beneath a row unit (152) of a corn harvesting device (108) comprises a first blade (134) and a second blade (136), which are placed or affixed beneath the row unit (152) of the corn harvesting device (108) and which can be made to rotate around at least essentially vertical rotational axes. The enveloping circles of the blades (134, 136) overlap beneath a plant stalk delivery area (154) of the row unit (152) of the corn harvesting device (108). The blades (134, 136) impact, from various directions, on plant stalks that are delivered downward from the row unit (152).
