PROBLEM TO BE SOLVED: To attach a linear member for grass winding prevention to the vicinity of an external periphery of a claw shaft in a rotary tiller in which tilling claws are attached to flanges.SOLUTION: A plurality of flanges 4 are arranged in a claw shaft direction at an external periphery of a claw shaft 3 which is rotatably drive-supported to a rotary machine frame 10 around an axis, and tilling claws 2 are attached to the respective flanges 4. Penetration holes 5 penetrating in the claw shaft direction are formed at all the flanges 4, linear members 6 for grass winding prevention are made to penetrate all the penetration holes 5, and come-off prevention means 7 for inhibiting the come-off of the flanges 4 located at both external end sides of the claw shaft direction to the inside of the claw shaft direction from the penetration holes 5 are arranged at both ends of the linear members 6. |
