The boring machine is disclosed which includes a power and control unit having a power source which uses a large electrical motor, a large hydraulic pump and a torque convertor connected to a speed reducer which controls the speed and torque provided to the auger and cutting head. A second small electrical motor and small hydraulic pump are used to power two hydraulic cylinders for pushing the string of pipe casings into the bored hole using a master pusher. A structural protector frame provides safety protection for an operator seated within the power and control unit. A control console is used by the operator for operating and controlling the boring machine and the direction of the string of pipe casings in the bored hole. Steering and pipe control cables extend into the bored hole from a wire spool mounted on the front of the power and control unit. A generator power by a diesel engine located outside the pit area provides electrical power for the electrical motors. The result of this new power and control unit accomplishes the objectives of a safe and efficient boring machine and boring operation.
