Claim 1
Independent Claim
165 words
A blacktop cutter attachment adapted to be mounted on the lower edge of a blade or bucket of a conventional earth moving vehicle comprising a combination surface guide and support for guiding the cutter attachment along a blacktop surface and having a rear transversely extending slot for receiving the lower edge of a blade or bucket of a conventional earth moving vehicle for supporting the attachment thereon, and a depending cutter plate fin fixed to the combination surface guide and support having a forward cutting edge for cutting the blacktop surface as the cutter attachment is driven therealong by the earth moving vehicle, the combination surface guide and support having surface guide portions on both lateral sides of the depending cutter plate fin engageable with the blacktop surface for assisting in guiding the cutter attachment along the blacktop surface with the cutter plate fin depending into the blacktop for cutting the blacktop as the attachment is driven along the surface by the earth moving vehicle.
