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. The unique and novel structure of the blade draws the earth cut by the cutting edge rearwardly and upwardly towards the cutter of the blade, and then rolls the earth forwardly of the blade, thereby decreasing the frictional resistance of the load and increasing the load which can be carried by the earth-moving machine.
