ABSTRACT:
A trenching attachment for use on a toothed earth moving bucket which converts conventional backhoe or similar earth moving machines into devices capable of excavating a continuous trench. The attachment may be mounted on any toothed earth moving bucket, and includes an anchoring and connecting arrangement which transfers a substantial portion of the frictional drag load generated during trench excavation operations from the attachment to the base of a backhoe's articulated boom. Furthermore, during trenching operations, the operator may control the depth of the V-shaped excavation with the backhoe or similar earth moving machine's hydraulic controls as such is driven forward, creating graded trenches for the installation of subsurface conduits, cables and the like.
