A soil leveling apparatus (10) is disclosed which includes a frame (11) having ground-engaging members (12a, 12b, 12c, 13) disposed transverse to the direction of motion, side rail members (14, 15) in which the ends of the ground-engaging members are secured, and upstanding connecting means (20) for operatively attaching the apparatus (10) to the draft vehicle. A scarifying means (50) for breaking up and loosening the soil prior to the leveling operation can be mounted near the forwardmost area of the apparatus (10). The scarifying means (50) includes a cross-shaft (51), connector arms (52) for pivotally connecting the cross-shaft to the frame (11), scarifiers (55) extending downwardly from the cross-shaft and a hydraulic cylinder (61) for lowering and raising the scarifying means into and out of the soil. Another embodiment incorporates a scarifying means (50) having scarifiers (66) which maintain a constant orientation during lifting and lowering by a self-camming action.
