Abstract
A pilot tube drive assembly used with an auger boring machine includes a height adjustment mechanism for aligning the pilot tube path of travel with an axis about which an auger of the machine rotates during trenchless installation of underground pipe. A drive mechanism mounted on a drive assembly frame drives the pilot tube to form a pilot hole in the ground for guiding the auger. The height adjustment mechanism may include shorter and taller mounting assemblies which are typically removably mounted on the drive assembly frame. The shorter and taller mounting assemblies may be alternately mounted on the frame at the same location. Typically, the mounting assemblies are removably mounted on spaced rails of an auger boring machine frame via mounting legs which are removably inserted into openings in the spaced rails by an actuating mechanism between the rails.
