PROBLEM TO BE SOLVED: To simply and easily mount an end part of a linear member that is used for preventing grass winding.SOLUTION: A grass winding prevention mechanism of a rotary tiller is characterized by: fixing a large number of claw brackets 4 for mounting tilling claws 3 spaced apart in a claw shaft direction and a circumferential direction on an outer circumferential surface of a claw shaft 2 rotatably supported around an axial center; providing a supporting member 6 to each of the claw brackets 4 positioned at both ends in the claw shaft direction; and mounting both ends of a linear member 5 for preventing grass winding to both supporting members 6. The linear member 5 has an enlarged diameter end member 7 forming a tip enlargement part 7b of a diameter size at an end part. The supporting member 6 is formed with an engagement hole 8 detachably engaged with the enlarged diameter end member 7. The engagement hole 8 has an enlarged diameter hole 8a with a tip enlargement part 7b of the enlarged diameter end member 7 insertable therein, and a detachment prevention groove 8b in communication with a direction approaching the claw shaft 2 from the enlarged diameter hole 8a and passing the linear member 5 while preventing detachment of the tip enlargement 7b. |
