A farm implement having a main frame; at least two carriage wheels for supporting the frame; a plurality of brackets mounted in pairs on the frame, each pair of brackets defining a sled; a plurality of knives mounted on each sled in a generally horizontal plane; a weeder bar rotatably supported by the brackets; and a hydraulic motor mounted on the frame for driving the weeder bar in a counter clockwise direction as the implement is moved in a direction whereby the carriage wheels rotate in a clockwise direction.

A farm implement useful to cultivate field crops and to prepare soil comprising: (a) a main frame; (b) at least two carriage wheels for supporting the frame; (c) a plurality of brackets mounted in pairs on the frame, each pair of brackets defining a sled; (d) a plurality of knives mounted on each sled in a generally horizontal plane; (e) a weeder bar rotatably supported by the brackets; and (f) a hydraulic motor means mounted on the frame for driving the weeder bar in a counter clockwise direction as the implement is moved in a direction whereby the carriage wheels rotate in a clockwise direction; said weeder bar is positioned above said knives; said knives protrude and are mounted on each sled in such a manner whereby protruding knives from adjacent sleds do not overlap to prevent the balling up of weeds, trash, or the like, between knives from adjacent sleds; said sled comprises two generally U-shaped brackets, each bracket having a base, a frame attachment arm, and a free arm, said frame attachment arm attaching to said frame; at least one cross member connecting to the free arm of each U-shaped bracket; at least one diagonal connecting support member connecting to the base and frame attachment arm of each U-shaped bracket; each U-shaped bracket includes at least one knife blade connected to the base thereof such as to be generally parallel to the ground and diverge with respect to the base; said weeder bar being rotatably supported by the base of each bracket.
