Developments in Tractor Design

Economic background is discussed with consequences for tractor industry and tractor concepts. Particular reference is given to the question of frame chassis instead of block concept. Development trends of tractor components are analyzed for driving system (including four-wheel drive and brakes), diesel engines, transmissions, human engineering , hydraulics and implement control. Consideration is given to electronics and aspects of environmental protection as well. Expected further tractor design developments are summarized at the end of the paper.
