A sweep is disclosed for use with an earth-cultivating implement and includes an elongated body terminating in a front nose portion. A stem is provided for attaching the body to the implement. A pair of laterally extending wing members diverge rearwardly from the body, each terminating at one end with the body to form the front nose portion while terminating at its opposite distal end in a tip portion. Each wing member defines a continuous front cutting surface along its forward edge between the nose and tip portions thereof, the cutting surface being shaped in a concave curve between the nose and tip portions. Finally, each wing member further defines a substantially uniformly curving concave bottom surface which extends between the front cutting surface and the rear edge of the wing member.
