<p>PROBLEM TO BE SOLVED: To provide a structure for preventing winding of grass and straw of a rotary tiller which can prevent a long-culm such as grass and straw from being wound around a cultivating shaft without installing a linear member.SOLUTION: The rotary tiller includes a plurality of cultivating claw mounting bodies that are mounted to an outer periphery of the cultivating shaft so as to be protruded while separating apart from each other in the axial direction thereof, where a base end part of a cultivating claw is mounted to each cultivating claw mounting body. In the rotary tiller, a tubular grass and straw winding prevention body having an internal diameter that can cover an end surface of the cultivating claw mounting body is disposed between the cultivating claws adjacent to each other in the axial direction of the cultivating shaft so as to be concentric with the cultivating shaft, and the outer periphery of the cultivating shaft is covered by the grass and straw winding prevention body.</p> |
