PROBLEM TO BE SOLVED: To provide a tilling claw improved in functions on tilling work such as soil-crushing property and leveling property. SOLUTION: This tilling claw 1 equipped with a length-wise blade part 3 mounted at the periphery of a shaft of a horizontal rotary shaft in radiating directions and formed continuously from its mounting base part 2 and a width- wise blade part 4 formed as curved to one side and at the tip side of the length- wise blade 3, is obtained by bending the base part of the length-wise blade 3 in a reverse side at a prescribed angle to the width-wise blade part 4, forming a blade edge 7 as a single side edge at the curved side of the width-wise blade part 4 from the length-wise blade part 3 to the tip of the width part blade 4, forming the length-wise blade 3 to have a slight curve so that the curved side of the width-wise blade 4 forms a recessed surface and the other side forms a protruded surface, and forming the width-wise blade 4 to have its tip part of the back edge bending slightly toward its outside for forming its cross-sectional shape to have a gradual S-shape from the bent part from the length-wise blade part 3 to the tip part of the back edge 1.
