Patent attributes
A cutting edge attachment including a cover retaining plate and a cutting edge is provided. The cover retaining plate includes through-hole bushings extending outward for receiving a corresponding number of fasteners to mount the cutting edge to an adapter plate. The cutting edge includes elongated openings for receiving the bushings, a top edge having notches for receiving springs, and a bottom edge. The cover retaining plate is configured to secure the cutting edge to the adapter plate using fasteners inserted through the bushings, the elongated openings of the cutting edge, and holes defined in the adapter plate. The springs are disposed between the notches and a top edge extension of the cover retaining plate and configured to compress in the vertical direction. The cutting edge is configured to move vertically as the bushings travel within the elongated openings when an upward force is applied to the cutting edge.
