The profiler comprises a chassis with a unit for moving the chassis and for providing power to the profiler. A controller operates the profiler, with a single percussive device associated with the chassis. A parallelogram boom is affixed to the chassis. The percussive device is affixed to the parallelogram boom, with a member for positioning the percussive device, and a flat faced bit extending from the percussive device. The parallelogram boom includes a vertical support pivotally affixed to the chassis, a mast, a support bracket pivotally affixed to the vertical support and the mast. A support beam is pivotally affixed to the vertical support and the mast and a member displaces the parallelogram boom.
