Abstract
The present disclosure relates to an auger boring machine for boring through the earth. The auger boring machine includes a cutting head for engaging a working face of the earth to cut a bore. The cutting head is rotatable about a drive axis so as to cut the earth at the working face. The auger boring machine further includes an auger that is rotatable about the drive axis for transporting spoil resulting from the operation of the cutting head away from the cutting head. Additionally, the auger boring machine includes a casing housing the auger which is urged to move into the bore behind the cutting head. The cutting head and the auger are movable along the drive axis relative to the casing. Furthermore, the auger boring machine includes a steering member positioned near the cutting head for directing movement of the casing into the bore in a steered direction transverse to the drive axis.
