Abstract: The movable blade for attachment to a material moving machine is a generally rectangular blade for hinged attachment to a machine shovel, box grader blade or other similar device mounted on the machine. The movable blade angle of extension or retraction relative to the machine is controlled by a hydraulic cylinder, brace or other structural element. When the movable blade is extended outwardly at an angle relative to the machine the machine may be operated parallel to the material to be moved. This action relative to material positioned next to a ditch allows the operator to fill the ditch with material in a continuous operation along the ditch rather than requiring short movements at an angle to the ditch to move the material. The movable blade may also have a rotational mechanism to raise and lower the extension end for use in slope grading adjacent a roadway as an example.
