A stalk stubble flattening an slicing apparatus for use on agricultural implements for harvesting row crops to bend over stub stalks to prevent undue wear and damage to tires of the implement. A plurality of slicing disc blades are mounted on a shaft that is rotatably mounted by bearings to a top surface of a curved flattening plate. The shaft is perpendicular to, and the disc blades are parallel to, the direction of travel. A plurality of corresponding slots are provided through the flattening plate such that the perimeter edges of the discs extend therethrough below the bottom surface of the flattening plate. The blades travel over the stalks and slice them longitudinally.
