Abstract
An auger boring machine having a drive mechanism for moving the machine along a desired direction of travel includes a drive motor having a shaft and a pinion mounted on the shaft. A method for manufacturing a track for such a boring machine includes providing a track base rail adapted to support the auger boring machine and arranging the base rail along the desired direction of travel of the boring machine. The method also includes cutting a gear rack which includes a plurality of gear teeth along one side that are adapted to mesh with the pinion of the drive mechanism, and a flexibility notch on the side opposite the gear teeth. The gear rack is attached to the base rail with the gear teeth oriented so as to engage with the pinion of the drive mechanism.
