Abstract: A system for erecting and changing the position of the drill column of an earth boring machine. The drill assembly is held in place by supports pivotally mounted upon a base. Brace means are attached to the supports which hold the drill assembly in position. Linkages may be attached to drill assembly and the brace means removed. Movement of the main thrust cylinder in the drill assembly causes the support means and consequently the drill column to change position. Support members may again be put in place to hold the drill column in position.
