The drive shaft extends through the sleeve. A transmission housing is coupled to the sleeve opposite the motor. The drive shaft extends into the transmission housing. A foot assembly is rotatably coupled to the transmission housing. An angle of the transmission housing and the sleeve is adjustable with respect to the foot assembly. The foot assembly vibrates when the motor is actuated to tamp the asphalt or the stone and the foot assembly is drawn across the asphalt or the stone.
