PROBLEM TO BE SOLVED: To provide a tilling rotary structure securing sufficient mounting strength, facilitating mounting/changing work and variably adjustable in soil digging width.SOLUTION: Brackets 21A, 21B of a tilling rotary structure include a boss mounted to a rotationally driven tilling shaft 17 of a tiller so as to rotate integrally with the tilling shaft, and mounting plates of flat plate shape having projecting pieces radially projected from the outer periphery of the boss. Claw rotors 22A, 23A, 23B have rotor faces of flat plate shape having openings that can axially insert the whole brackets including the projecting pieces, and claws 24A, 24B radially projected from the rotor faces. The claw rotors are fixed to the brackets in relative rotating angle positions where the brackets cannot be inserted. The claw rotors can be fixed on either the inside or outside of the mounting plates of the brackets. |
