REVERSIBLE BOTTOM PLOW IMPLEMENT

摘要

PROBLEM TO BE SOLVED: To provide a reversible bottom plow implement capable of reversing a reversible frame by making a half turn of the frame after the temporary neutral state of the reversible frame according to the reversing motion of the implement. SOLUTION: The reversible bottom plow implement is provided with bottoms attached plane-symmetrically above and below an implement frame constituting the bottom plow implement. The implement frame is provided with a reversible frame reversed by a reversing cylinder and attached to a mast through a rotary shaft. The mast is positioned at the center of the working width direction. An end of the reversing cylinder is pivoted to the mast and the other end is pivoted to the reversible frame. The mast has a stopper protruded in a motion region to perform the reversion motion of the reversing cylinder and inhibit the rotation of the reversible frame in the neutral state of the reversing cylinder. There is no problem of the protrusion of the frame to the adjacent traffic lane to cause the inhibition of the overtake of the following vehicle or the hindrance to the passage of the oncoming vehicle.
