Abstract
A grading implement including main body having a left end, a right end and a length that extends between the left and right ends. The main body also includes a front side and a back side. A claw-blade is positioned at the front side of the main body. Side blades are positioned at the left and right ends of the main body. The side blades include portions that extend rearwardly from the main body so as to define a volume located behind the back side of the main body between the side blades. The volume receives grading material when the implement is moved rearwardly.
