A soil penetrating tool assembly for mounting to a tool bar of a soil penetrating implement including a shank member which has an elongate body, a soil penetrating tool which is located on the first end of the body and a facing plate located on a second end of the body. The facing plate engages one side of the tool bar, and has a first end and a second end which has an opening. A clamping plate engages the other side of the tool bar, and has a first end and a forked second end which has two prongs each having openings including two sections, generally oblong in cross-section, offset from one another with different centerlines. The facing plate first end and clamping plate first end include facing flanges each having a through hole and a bolt secures the flanges together with a clearance therebetween. The opening sections in each of the clamping plate prongs and the facing plate opening define a generally cylindrical passage therethrough with a selected diameter when the shank member is mounted to the tool bar, and a shear pin extends through that defined passage. |
