Abstract: A truck mounted boring system providing a high degree of radial and longitudinal freedom. The system provides a method of quickly setting up a boring system used for directional drilling of underground cabling bore holes. A hydraulic system providing power to the boring system is run by a power take off of a truck. The truck is used to position the boring system. The boring system employs a rotatably mounted hydraulic actuator which radially and axially changes the orientation of the drilling system. The drill bit is driven into a boring hole using a linear chain drive. The chain drive is mounted on a boring platform that can achieve motion relative to the truck or drive the drill toward the bore hole in response to a restraining bar.
