PROBLEM TO BE SOLVED: To prevent soil from being attached to a tilling shaft, or a bolt or a nut for fixing tilling tines to the tilling shaft. SOLUTION: The tilling implement is equipped with a tilling rotor 10 supported so as to be freely rotatable. The tilling rotor 10 is equipped with the tilling shaft 11 rotating by receiving the power from a traveling machine body, and the tilling tines 15 arranged on the tilling shaft 11, and has a through-hole into which the tilling shaft 11 between the neighboring tilling tines 15 installed in the shaft direction of the tilling shaft 11 is inserted, and a ring body 20 to be attached to the tilling shaft 11 by allowing the tilling shaft 11 between the neighboring tilling tines 15 to be inserted to the through-hole, and having a width shorter than the distance between the neighboring tilling tines 15. The ring body 20 has unevenness 29 formed in the terminal parts in the width direction. The ring body 20 is freely rotatable based on the tilling shaft 11 and freely movable between the neighboring tilling tines 15 in accordance with the rotation of the tilling shaft 11.
