This disc plough was seen at the Australian National Field Days at Orange in New South Wales last November. It was designed with the help of scientists from the Australian Commonwealth Scientific and Industrial Research Organisation. They looked at all the forces acting on a plough and fed their figures through a computer. This information was given to the plough makers at John Shearers, who built the implement. The plough beam is filled with concrete, and the jump mechanisms are individually controlled by hydraulic pressure. The discs can jump a hidden rock and then return gently to their working cut.
