Abstract
A vibratory plow assembly which provides improved vibratory plowing through the mounting of the plow blade and maneuverability of the assembly. The assembly includes a forward frame member, a rearward frame member, and spaced apart link members pivotally connecting the frame members to permit relative vertical movement. A plow blade and gage wheel holder is pivotally mounted to the rearward frame member which also includes a vibrator for the plow blade. The forward frame member is pivotally mounted to a vehicle for movement about a vertical axis, and the plow blade holder is pivotally mounted to the rearward frame member for movement about a vertical axis. Further, the assembly is constructed such that the plow blade moves into a tucked relationship with respect to the connecting links between the frame members, thereby permitting loading and unloading of the plow assembly without the need to remove the plow blade. The disclosed vibratory plow assembly utilizes a combination of boom steering and blade steering for moving the plow blade laterally relative to the center line of the vehicle to permit offset plowing next to buildings and the like. Moreover, the blade holder provides improved and efficient mounting of the plow blade, and the gage wheel construction assists in the maintenance of constant blade and cable burial depth regardless of the contour of the ground surface.
