Abstract

A linkage assembly for a vibratory plow. A vibratory plow comprises a power unit and a vibratory plow assembly. The vibratory plow assembly has a linkage assembly to connect to the power unit. The linkage assembly comprises a lift trolley, an upper arm, a lower arm and a load transfer link. The upper arm is pivotally connected to an upper end of the lift trolley. The lower arm is pivotally connected to a lower end of the lift trolley. A vibrator assembly is connected to the upper arm and the lower arm and a plow assembly comprising a plow blade is connected to the vibrator assembly. The load transfer link is operatively connected to the upper arm and to the vibrator. The load transfer link may be a leaf spring with an intermediate link. Alternatively, the load transfer link may be a hydraulic cylinder or an elastomeric member.
