Abstract
An under-frame shield, particularly useful with crop sprayers and other implements which traverse fields of plants, includes one or more flexible sheet material shields connected to axle structure and to a central rigid shield by resilient connectors to facilitate suspension system movement in all directions without sacrificing ground clearance. The connection structure and sheet material shields maintain a smooth, seamless protective surface on the under side of the machine to reduce vehicle and crop damage.
