Abstract
A drilling machine includes a mast, a rotary head movably coupled to the mast, a drill string component having a pair of opposed flat surfaces, and a securing structure including engagement surfaces shaped to engage the opposed flat surfaces and secure the drill string component from rotating. The drilling machine also includes a controller configured to track a rotational location of the flat surfaces of the drill string component during rotation of the drill string component. The controller is further configured to receive tracking information from a sensor associated with the rotary head and control the rotary head to align the opposed flat surfaces for engagement by the securing structure.
