Abstract: Employee #1, of John R. Anderson Farms, was working on a farm as an irrigator. An irrigator moves irrigation lines in fields to make sure crops receive water. Employee #1 was working with a wheel line, a system of irrigation pipe supported by large metal wheels. The water line becomes part of the wheel's hub. The system is powered by a gasoline engine that moves the entire line as one unit across a field. The engine has chain and sprocket drives that are attached to the wheel that moves the system. Employee #1 was preparing to move the wheel line when the main drive chain came off its sprocket. Employee #1 attempted to put the chain back on the sprocket while the unit was running. His fingers were run through the sprocket and chain. Employee #1 sustained a finger amputation and was hospitalized.
