<P>PROBLEM TO BE SOLVED: To provide a wheel for agricultural use capable of preventing the lifting of mud, and preventing damage to seedlings and worn-out of cultivated fields caused by dropping mud. Ž<P>SOLUTION: The wheel 1 for agricultural use, the rotational direction of which is designated during normal operation, includes a plate-shaped blade lug 16 protruding toward both sides in the axial direction in which an inner end 17 in the radial direction is provided closer to the rotational direction than an outer end in the radial direction on both the sides. A plurality of grooves 22, 23 extending from the inner end toward the outer end are provided on a surface 21 facing the rotational direction of the blade lug. A value obtained by dividing a total A of the widths of the grooves in the axial direction by a value B obtained by subtracting the total of the widths from a distance between both end edges in the axial direction on the surface is 0.25 or more and 0.76 or less. A value obtained by dividing an average value C of the depths of the plurality of grooves by a thickness D of the blade lug is 0.2 or more and 0.5 or less. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
