<p>PROBLEM TO BE SOLVED: To provide tilling claws in which the tilling resistance can be reduced while improving harrowing performance.SOLUTION: An agricultural machine 1 includes a machine body 2 connected to the rearward of a tractor, a tilling body 6 for tilling work, and a leveling body 17 for leveling work. The tilling body 6 has a rotary shaft body 11, and two or more tilling claws 15 attached to this rotary shaft body 11. Each tilling claw 15 includes a planar base end side plate part 31, a curved middle plate part 32 continuously arranged to this base end side plate part 31, and a planar tip side plate part 33 continuously arranged to this middle plate part 32. The middle plate part 32 has a curvature radius that is gradually increased from the front end side in the rotation direction toward the rear end side in the rotation direction.</p> |
