Abstract: A vibratory rammer includes an upper mass, a lower mass coupled to the upper mass, a longitudinal axis extending centrally through the upper mass and the lower mass, and a handle coupled to the upper mass with a handle vibration dampening mechanism that is configured to attenuate vibration transmitted to the handle. The handle is configured to support a user interface on a first side of the longitudinal axis. A motor is coupled to the upper mass and a drive mechanism is operably coupled to the motor and the lower mass. The drive mechanism configured to move the lower mass in a reciprocating manner. A battery provides power to the motor and is coupled to the upper mass with a battery vibration dampening mechanism that is configured to attenuate vibration transmitted to the battery. The battery positioned on a second side of the longitudinal axis opposite the first side.
