Claim:
A box blade comprising: a plurality of rippers for extending into a surface, each ripper comprising an elongated slot extending therethrough; at least one scraping blade contactable with the surface. the scraping blade disposed rearwardly from the rippers; a generally horizontal support beam that extends across the box blade generally perpendicular to a direction of motion of the box blade, the support beam comprising a plurality of brackets, each bracket rotatably receiving a ripper, each bracket comprising a fastener extending through the elongated slot, the fastener rotatably affixing, the ripper to the bracket, the ripper rotatable around the fastener from a deployed position into a stowed position, each ripper rotatable deployable and retractable by a user, each ripper deployable and retractable independently from a position of the remaining rippers, wherein the ripper is rotatable around the fastener from the deployed position in which a ripper tooth is contactable with the surface, into the stowed position in which the ripper is rotated substantially 180 degrees until a ripper shank contacts a vertical wall of the horizontal support beam, and, wherein the ripper is lockable by pushing the ripper downward after the ripper is in stowed position, thus causing the fastener to contact a bottom portion of the elongated slot.
