发明名称 Trenching attachment for a backhoe
摘要 A trenching attachment for removable attachment to the bucket of a backhoe is disclosed which converts the backhoe from a stationary digging machine into a continuous trenching machine creating a V-shaped trench suitable for installation of pipes or conduits or the creation of fire breaks. With the attachment installed on the backhoe bucket the operator may control the depth of cut with the backhoe controls as the backhoe is moved forward, creating graded trenches for the installation of drainage or sewer lines.
