PURPOSE:To prevent the lateral slip of a wheel due to the presence of a stump and to ensure stable running by forming a pair of guide walls on both sides to guide a stump from both sides in a way to engage the outer peripheral part of a wheel with the stump, and forming lugs for thrust between the guide walls. CONSTITUTION:Wheels 2 for a wet rice field of an agricultural working vehicle, e.g. binder, to effect a work mainly in a wet rice field are engaged externally of an axle 10, laterally protruded from the lower part of a mission case 4, in a manner that positions on both sides are regulatable. In this case, a pair of guide walls 11 on both sides for guiding a stump are formed on the outer peripheral part of the wheel 2. Lugs 2a and 12 are formed in the outer peripheral surface of a tire and a bottom between the guide walls 11, respectively, on both sides. The guide walls 11 are disposed in a manner to be displaced internally of the wheel 2, and a distance between the wheels is regulated so that a distance between the guide walls 11 on both sides is adjusted to an interline distance. An agricultural vehicle is run in a state that the stump is engaged with a space between the guide walls 11 on both sides, and the lateral slip of the wheel 2 is prevented. |
