Abstract
A drive wheel attachment for a self-propelled irrigation system includes an annular-shaped clamping band assembly having multiple sections that fit around and clamp to existing wheel rims. A plurality of circumferentially spaced, radially extending structures are secured to and extend radially outwardly from the clamping band assembly. A plurality of foot assemblies are attached to the radially extending structures. Each foot assembly includes a first hinge sleeve removably attached to a respective one of the radially extending structures, and a ground engaging foot pad pivotally attached to the first hinge sleeve by a pair of second hinge sleeves and a pivot pin extending through the first and second hinge sleeves. The pivot pin is fixed to the second hinge sleeves and allows rocking movement of the foot pad relative to the radially extending structure about a pivot axis that extends generally parallel to an axial direction of the wheel rim.
