ABSTRACT:
A plow assembly includes a housing, a shaft having a first eccentricity and a shaft having a second eccentricity. The shaft having a first eccentricity is mounted within the housing for rotation about a first axis of rotation, and the shaft having a second eccentricity is mounted within the housing for rotation about a second axis of rotation. The assembly also includes a surface breaker blade and a balancing assembly. The surface breaker blade is mounted on the shaft having a first eccentricity in such a manner that rotation of the shaft having a first eccentricity causes the surface breaker blade to move in response to the first eccentricity of the shaft. The balancing assembly is mounted on the shaft having the second eccentricity in such a manner that rotation of the shaft having the second eccentricity causes the balancing assembly to move in response to the second eccentricity of the shaft. The assembly also includes a mechanism for rotating the shaft having a first eccentricity about the first axis of rotation, and a mechanism for rotating the shaft having a second eccentricity about the second axis of rotation.
