ABSTRACT:
An improved wheel construction for agricultural apparatus, such as wheel-move irrigation pipe lines, has a hub and an annular rim joined by spokes releasably attached at their ends to the hub and rim in a manner such that the wheel may be knocked down or disassembled for storage and shipment and easily assembled at the point of use. The inner spoke ends are releasably joined to the hub by unique coupling structure which are engagable to firmly interlock the spokes to the hub and are releasable to separate spokes from the hub solely by relative movement of the spokes and hub between interlock and release positions.
