PROBLEM TO BE SOLVED: To provide a tilling claw which reduces tilling vibration and horsepower consumption by suppressing stress concentration caused when a tilling claw is driven into soil and load changes caused thereby, and shows excellence in tilling performance in throwing force, rotation, plowing, soil crushing, and land leveling.SOLUTION: A tilling claw comprises: an attaching base (1) fitted to an attaching flange (S0) of a rotation claw shaft (S); a vertical blade part (2) with a blade edge which is formed by a flat plate up to a lateral blade curvature start part (G) continuously extending in a lateral direction from the attaching base (1) viewed from the side when the surface with the rotation shaft axis of the rotation claw shaft (S) as a normal line is taken as a side surface, and which is formed downward from the lower edge of the attaching base (1) through a level difference; and a lateral blade part (3) formed by a curvature plate which is continuously extends from the vertical blade part (2), with the lateral blade curvature start part (G) as a boundary, the curvature plate being formed with a width size equal to or greater than the width size of the attaching base (1) from the vertical blade part (2) to the tip side, the curvature plate being formed gently curved upward in side view, and the curvature plate being curved to one side, with the lateral blade curvature start part (G) as a boundary. |
