PROBLEM TO BE SOLVED: To insure tractive force performance capable of dealing with increase of power of a farming machine. SOLUTION: This invention concerns a wheel for farming in which flat-plate- like wings 8 bendingly deformable in the circumferential direction and elastically restorable after deformation are integratedly formed at substantially regular intervals in the circumferential direction on an elastic wheel body 7. In this wheel for farming, the flat-plate-like wing 8 is projected in the radial direction from the elastic wheel body 7, it is constituted of a large wing part 9 of large projection on one side in the axle direction and a small wing part 10 of small projection on the other side, the bite-in earth side of the large wing part 9 is formed into a flat plate part 9A on the radial line 0 of the wheel, the radially inside part 9B continued to the flat plate part 9A is spread toward the radially inside end at a fixed angleθfront and rear in the circumferential direction against the radial line O of the wheel, and the angle 9 of the large wing part 9 is set 66-180, so as to make penetrating resistance in the earth optimum and prevent the wheel from sinking.
