ABSTRACT:
A drain ditch digging attachment which is used with a back-hoe and which is provided with a generally V-shaped bucket for removing ground to form an elongated drainage ditch down or along a slope. The attachment has a long transverse reinforcing bar across the bucket and extending beyond the opposite ends thereof, such extensions having ground cutting and moving members such that the attachment not only digs the ditch but also forms the edges or sides of the ditch in one single pass of the attachment without the need for additional manual labor.
