A plow trenching apparatus for a vehicle having a raisable boom structure, for example a skid steer vehicle. The apparatus comprises a tool attached to a tool mounting plate of the boom structure. The tool has an arm mounting plate, attachable to the tool mounting plate, a J-shaped curved arm having an arm mount arranged at one end and a plow holder mount arranged at the other end, a plow holder attachable to the plow holder mount, the plow holder mount permitting the plow holder to pivot horizontally, a plow attachable to the plow holder, and a hydraulic cylinder. The arm mount is attachable to the arm mounting plate via an arm pivot attachment. The curved arm is horizontally pivotable at the arm mount by the hydraulic cylinder. The hydraulic cylinder is extendable and retractable and attached to the arm mounting plate via a hydraulic cylinder attachment and attached to the curved arm via an arm pivoting attachment arranged on the curved arm.
