A device for driving ground rods of the type to be mounted on a suitable carriage or vehicle. A boom to engage ground rods as the rods are driven is attached to an adjustable horizonal beam. The adjustable horizonal beam interconnects the boom with a vertical cylinder attached to a base. The base interlocks the entire device to the bed or frame of the carriage. The movement of the horizonal beam and rotation of the vertical cylinder combined as a means of positioning the boom relative to the carriage. Attached to the boom is a hydraulically driven impact hammer for power driving the ground rods. The boom is pivotally mounted on the horizonal beam so that the boom may be carried in a substantially horizonal position while in transit and rotated to a vertical position when in use. Also included is a vertical adjustment means mounted on the beam so that the boom may be adjusted vertically to engage with the ground or supporting surface on which the vehicle rests.
