Abstract
A wheeled, self-propelled apparatus has a percussion tool or hammer mounted on its forward end and an impact transmitting means carried on the tractor below the hammer. The impact transmitting means is adapted to be mounted to transmit repeated impacts from the hammer to a cemetery marker until the latter is flush with the ground surface where it will not interfere with ground maintenance, such as lawnmowing and the like.
