ABSTRACT:
A wheeled, self-propelled tractor 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 comprises a metal frame having a strong rigid top plate that is struck by the hammer and a downwardly opening cavity in which wood timbers are mounted to transmit the impact from the plate to a cemetery marker. Repeated blows to the marker applied through the impact transmitting means will drive the marker into the ground until it is flush with the ground surface where it will not interfere with mowing. The frame is fastened on the vehicle by a suspension system that includes tension springs which keep the wood timbers in a horizontal plane but permit the frame to move downwardly each time it is struck by the hammer.
