On-board vehicle electronics has matured and become a practical replacement for mechanical type control systems. Electronic control systems typically allow more application flexibility and performance enhancement potential than the mechanical control systems they replace. This paper will cover the electronic three-point hitch control on the John Deere 55 Series row-crop and 60 Series 4WD tractors. It will explain how the use of electronics has provided a more flexible system with adaptation to different vehicle configurations. It will also show how electronics has provided improved serviceability and performance.
