ABSTRACT:
A trenching plow blade having replaceable wear components is disclosed. A preferably octagonal rod with regularly spaced transverse holes drilled therethrough is welded to the leading edge of the blade. Replaceable leading edge cover pieces each have a channel therein with a shape complementary to the front face of the rod, and transverse holes adapted to align with the transverse holes in the rod. Pins are positioned through the holes to hold the covers in place. Preferably, straight and curved sections of the covers are provided as required. For the toe of the blade, a toe cover is preferably provided. The rod and covers may be supplied as a kit, which is readily installed since the only operation required is welding.
