(under the class definition) Apparatus in which the unearthing apparatus is provided with a ground penetrating means of substantially flat shape lying generally in or parallel to a vertical plane extending in the direction of draft for the disclosed function of constraining the movement of the apparatus over the earth to a desired path.
(1) Note. This subclass includes those stabilizing fins or colters which are inclined relative to the direction of draft at such an angle with respect to an associated angularly disposed unearthing apparatus as to thereby counteract the side draft caused by such angularly disposed apparatus and thus maintain the same in a straight line in the direction of draft.
