ABSTRACT:
An apparatus for splitting a concrete block and pitching at least one edge of the split concrete block is provided. The apparatus includes a splitting blade have a blade edge, such as a sharpened edge or a dull edge. The splitting blade is configured to move in a first direction so as to split a concrete block into two or more sections. The apparatus also includes a pitching blade having a blade edge, such as a sharpened and adjacent to the splitting blade, the pitching blade edge vertically offset from the splitting blade edge so as to pitch an edge of one of the sections of the concrete block after the concrete block has been split.
