Abstract: An electric auger-boring machine. The machine has electric motors for auger rotation and thrust. The electric rotation motor rotates the auger at a constant rate when the current provided is constant. The motor may slow or stop in response to changes in torque due to obstructions to auger rotation. Electric motors allow for auger thrusters and actuators to precisely operate. A wireless remote control controls motor and auger rotation and thrust from a distance away from a launch pit. Multiple sizes of product casings may be utilized and the auger-boring machine comprises an adjustable adaptor and saddle for use with a plurality of casing sizes.
