A ground supported mobile machine appropriate for subterranean installation of piping and the like has a tractor vehicle carrying a trencher driven from the tractor power source, a power operated backfill blade operated from such source to facilitate transporting a tool and drill rod holder, and a vertical drilling attachment powered from the tractor power source; this drilling attachment including a vertical mast providing guide rails for the carriage of a rotary drill head that is reciprocated by a hydraulic actuator along such rails to raise the vehicle to enable positioning stabilizing feet for a vertical drilling operation, manipulate the drill rod and drill bit thereon in performing such a drilling operation, and push piping into the drilled hole upon completion of such drilling operation. A drill table is associated with the vertical mast which carries hydraulically actuated slips to grippingly engage the drill rod to preclude undesired downward rod movement while permitting upward movement of the rod relative to such slips and pipe wrench tongs operable to break free a threaded joint between drill rod sections or a rod section and the drill bit. The drilling attachment further includes a pipe pusher having an upper piping clamp releasably attachable to the drill head carriage to move therewith in pushing piping into the drilled hole and a lower piping clamp releasably attachable to the drill table to guide and hold the piping during the pipe pushing operation.
