ABSTRACT The invention is a tooth mountable on a bucket of the digging wheel of a wheel-type ditching machine. The tooth has its ends angularly offset from each other, and the digging end has a generally U-shaped cross-section formed by a central section and a pair of integral outer flange sections. A series of elongated members of high wear resistance extend through the central section and are adapted to impact with the ground during the digging operation. The tooth of the invention has shown greater resistance to wear than previously-known types of teeth when used in permafrost conditions.
