    Abstract: A non-pneumatic tire for a wheeled tower of an in-field irrigation system has a circular array of hollow cavities within the tire body. In cross-sectional planes lying normally of the rotational axis, each cavity has a circumferentially elongated cross-section of greater circumferential length than radial width. Bulbous and concavely rounded terminuses of each cavity impart a dumbbell shaped cavity profile that omits stress failure points. The cavity width tapers in an axially inward direction toward a midplane of the tire, where the cavity width is narrowest. In use, collapse of the cavity at its narrow midpoint squeezes accumulate mud out from the cavities in self-cleaning fashion. The outer circumference of the tire features sloped areas whose axial measure decreases toward the midplane. In use of the tire, the sloped areas draw mud inwardly toward the midplane and self-fill the ground beneath the tire, and thereby lessening overall rut formation.

    Abstract: A tireless steel wheel for a skid steer features a cylindrical drum, a set of cleats projecting externally from the drum, a hub plate inside the drum an at intermediate location between opposing ends thereof, frustoconical walls flaring outward from opposing sides of the hub plate toward the respective ends of the drum, and annular end plates joining the wider ends of the frustotonical walls to the drum at the opposing ends thereof. The hub plate is offset from an axial center of the drum, and the frustoconical walls are unequal to one another in their angle of taper. The annular walls prevent the wheels from digging into the ground, and the frustoconical walls prevent material accumulation inside the wheels. The offset position of the hub plate provides flexible mounting options to accommodate varying dimensional characteristics of different skid steer models and bucket sizes.

    Abstract translation: 用于滑移转向器的不懈的钢轮具有圆柱形滚筒，从滚筒外部突出的一组楔子，在滚筒内部的轮毂板，在其相对端部之间的中间位置处，从与毂板的相对侧向外扩展的截头圆锥形壁朝向 滚筒的相应端部以及将截头锥形壁的较宽端部连接到滚筒的相对端部处的环形端板。 轮毂板从滚筒的轴向中心偏移，并且截头圆锥形壁在其锥度上彼此不相等。 环形壁防止车轮进入地面，并且截头圆锥形壁防止车轮内的物料堆积。 轮毂板的偏移位置提供灵活的安装选项，以适应不同滑移转向模型和铲斗尺寸的不同尺寸特征。
