PURPOSE:To stabilize coupling of a machine body, by providing a mounting mechanism which vertically and movably couples the machine body of a control working machine and laterally movably, laterally tiltably mounts the machine body to a mounting frame. CONSTITUTION:A control working machine 3 is vertically movably coupled to the rear of a running machine body 1 through a coupling mechanism 3. A machine body 27 is lowered through the action of a chain 18 with the aid of a hydraulic cylinder 10, a running machine body 1 is run through rotation of a driving shaft 31, and a boring body 42 is bored in field (a) earth. A bolt 22 of a mounting mechanism 19 is unfastened, the machine body 2 is laterally regulated and moved by laterally sliding a mounting arm 21 by means of right and left guide members 20 to laterally regulate and move the machine body 27, and lateral inclination of the machine body 27 is regulated through regulation of expansion and contraction of a regulating screw body 24. This enables variation of working attitude, and permits a machine body to be held in a stable horizontal state.
