An earth clod pulverizing and earth smoothing implement (10) has rows of heavy, cast-iron, pointed teeth (14a-v) which are wedge-shaped in cross section with the cutting edges (42) of the wedges defining substantially vertical lines facing the forwardly direction. The implement further includes downwardly directed channel irons (16a-d) after each row of teeth, with each successive channel iron being mounted slightly lower than the one in front of it. The front leg (54) of each channel iron is shorter than the back leg (56). The implement (10) also includes downwardly directed side walls (18a and b), an upwardly flared front member (20) and a downwardly flared rear, smoothing, member (22). A channel iron (16e) having equal sides is mounted on the downwardly flared smoothing member (22). The teeth are spaced two feet apart in the rows, and the rows of teeth are spaced 14 inches apart.
