Abstract
A directional drilling apparatus can be used in confined spaces or utilized in locations close to obstacles such as fences, houses, buildings, etc. A drill head is pushed forward or advanced. The drill head is of a design which provides a large amount of forward thrust for the size of the actuating unit and the drilling apparatus. The drilling apparatus is articulated from a source of power such as a prime mover and thus can be used in confined spaces.
