Blade for earth moving equipment

摘要

A blade for an earth moving machine mounted in the machine as to have at least one strip extending forward of the leading edge to engage and cut the soil by an oscillatory movement about an axis close to and parallel to the leading edge. A spading action is thereby produced which aids penetration of the blade into the soil so as to enable the soil to be more easily cut and shifted. The invention is applicable to many different kinds of earth moving machinery which cut and shift soil and increases the efficiency of earth moving machinery by increasing the soil cutting and moving ability attainable without relying on high tractive effort or increased power output.
