SOLUTION: The agricultural wheel includes an annular rim 4, a plurality of spokes 5 having one ends connected to the rim and the other end extend inwardly form the rim, and a boss 8 for connecting the other ends of the spokes inside of the rim. The spoke includes an offset part 12 inclining to a plane perpendicular to a central shaft of the boss, and an extension part 13 continuing from the offset part while forming a blunt angle with the offset part. The one ends of the spokes connected to the rim and the other ends connected to the boss are configured so as to be offset in an axial direction of the boss, and rib-shaped reinforcing plates 7 are fixed to the blunt angle formed portion on the side of the offset part and the extension part where the blunt angle is formed.
