ABSTRACT:
My invention consists of an attachment adapted to be connected to a road grader blade. It has a mounting means in the form of a frame for attachment to the blade, a support carried by said mounting means which in turn carries a curb shoe, the support being capable of being raised or lowered in order to position the blade in the proper horizontal plane. The vertically adjustable support carries a universal joint and the universal joint in turn carries a curb shoe which consists of an element having a relatively flat surface which engages a surface of the curb.
