PROBLEM TO BE SOLVED: To install a residual unplowed ground-treating claw having a vertical blade and a horizontal blade as projecting from a lower end part of a transmission case arranged with a plowing rotor from the lower end part to its side direction, to its lower direction and to improve the horizontal blade. SOLUTION: This residual unplowed ground-treating device by arranging the plowing rotor from the lower end of the transmission case 10, and installing the vertical blade 23a and horizontal blade 23b as projecting from the lower end of the transmission case 10 to its lower direction is provided by (1) installing the horizontal blade 23b of the residual unplowed ground-treating claw 23, having a scooping surface at the lower end part of the vertical blade 23a and also forming a turning the soil over action surface in the rear directional side of the machine body-progressing direction, and (2) forming the turning the soil over-action surface in the side blade 23b of the residual unplowed ground- treating claw 23 by extending the rear end part of the horizontal blade 23b in the rear direction and bending in upward direction. By the horizontal blade 23, the residual unplowed ground treatment in a whole area under the transmission case 10 is performed in a good accuracy. COPYRIGHT: (C)2003,JPO
