Abstract: A snow cutting tooth design and an associated cutter assembly design incorporating such teeth, wherein the tooth is constructed with a unitary body of steel plate welded to the outside surface of a tubular cutter bar, with bevelled edges creating acute snow cutting edges, along with a central notch also having bevelled edges and providing additional cutting edges as well as additional paths for churning and chopping the snow. The teeth are angularly joined along a centerline, dividing the tooth into a leading portion and a trailing portion, the leading portion being welded perpendicular to the centerline of the cutter bar. Some of the teeth have the rearward portion angled to the left side of the tilling machine, while others are angled to the left side, so that the snow is not moved to either side of the cutter assembly.
Abstract: A digging tooth for a loader bucket comprising a top surface having a concave configuration and a bottom surface having a flat forward portion and a convex rear portion. The flat forward portion and the top surface intersect to form a forward cutting edge. Sidewalls connect the two surfaces and are concave having a plowshare shaped. The rear portion of the tooth is provided with a mounting assembly for mounting it to a bucket. The bottom surface continuously converges from the forward cutting edge to the rear portion; whereas the top surface first converges than diverges from the forward cutting edge to the rear portion.
Abstract: A digging tooth for a bucket having a concave top surface and a convex bottom surface which intersect forming a forward cutting edge. Sidewalls connect the two surfaces and are concave having a moldboard shape. The rear portion of the tooth is provided with a mounting assembly for mounting it to a bucket. The bottom surface continuously diverges from the forward cutting edge to the rear portion; whereas the top surface first converges then diverges from the forward cutting edge to the rear portion.
Abstract: 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 top 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 continuously concave bottom surface which extends between the front cutting surface and the rear edge of the wing member.
