Abstract
A need to improve agricultural tractor productivity and in-field fuel economy has prompted the development of a new power shift transmission for John Deere Tractors. With all 15 forward speeds power shiftable under load, the operator can achieve and maintain an optimum match between implement load and tractor power for maximum fuel efficiency with little effort. Shift control, torsional vibration isolation, increased efficiency, and mechanical front wheel drive capability are vital parts of this new design.
