  • Patent number: 4445577
    Abstract: A blade suitable for attachment to an earth-moving machine is provided that substantially increases the size of the load that can be carried by the machine. The blade includes a pair of elongated, juxtaposed blade portions joined together at a common centerline to cooperatively define a chevron-shaped load bearing area. Each of the blade portions has a generally concave, earth-engaging forward face, and the before-mentioned centerline is recessed in relation to the outermost lateral edges of the blade portions. A generally triangular plate is secured to and depends from the pair of blade portions, and a detachable earth-cutting element is mounted on the lowermost generally horizontal edge of the plate.
