British Post Vibrator
Post Vibrator - John Lord built a machine that “vibrates” fenceposts into the ground rather than driving them. It’ll push big wood posts into the ground, pointed or not. The machine consists of a hydraulic vibrator mounted on the outside of a truck tire rim. The tire insulates the loader tractor from the vibration. (John Lord; simonjclord@gmail.com)
