Abstract
An agricultural implement includes a tool bar and at least one row unit carried by the tool bar. Each row unit includes a furrow opener arrangement with a gauge wheel. The gauge wheel includes a rim with an outer periphery and a tire mounted to the outer periphery. The tire includes an outer shell formed from a first resilient material and an inner core formed from a softer second resilient material. The outer shell is positioned radially outward from the inner core and axial outward from axial ends of the inner core. The inner core is mounted directly on the outer periphery of the rim and defines an annular hollow core therein. The tire is structured and arranged such that the softer inner core, the annular hollow core and the harder outer shell coact to provide good wear, good shock absorbance, and good mud shedding capabilities.
