  • Reversible tillage attachment for bidirectional mold board plow
    Patent number: 5172769
    Abstract: A tiller attachment for switchable bidirectional mold board plow which is adapted to be mounted onto the tool bar of the plow. The attachment includes a pair of axially spaced apart frame members which support arms joined at a right angles at a pivot point. The frame members lie in parallel spaced apart planes perpendicular to the axis of the tool bar and are pivotable from the right to the left side thereof. Tine bars are pivotably mounted to free ends of the frame members and are rotatable into ground engaging positions. An actuator which is responsive to the position of the plow rotates the frame members so that the tines firmly engage the ground behind the plow.
