PROBLEM TO BE SOLVED: To provide a tilling claw capable of smoothly switching a moving direction of tilling soil between inside and outside of a ridge.SOLUTION: In tilling claws 20L, 20R, in a state of being attached to a control machine 1, inner curve surfaces 23L, 23R, which curve toward inside of a width direction W of a machine body 10 of the control machine 1 as approaching a tip from sides of fitting base parts 21L, 21R, are formed at inner surfaces of one of driving side parts 22L, 22R among driving side parts 22L, 22R at the time of normal rotation and driving side parts 24L, 24R at the time of reverse rotation. On outside surfaces of the other driving side parts 24L, 24R, outside curve surfaces 25L, 25R are formed so as to curve toward outside of the width direction W of the machine body 10 as approaching the tip from the sides of the fitting base parts 21L, 21R. |
