In order to guarantee an efficient and economic working procedure, modern agricultural machines are generally equipped with extensive electronic control loops. Thereby some working steps can be automated and accelerated substantially. The tractor as a universally applicable machine is still one of the most important agricultural machines. The three-point-hitch of a tractor can operate a large amount of attachments. In order to arrange the three-point-hitch more flexibility, a system was developed which used three independently adjustable, position controlled hydraulic cylinders. If all linkages are adjustable the degree of freedom can be substantially extended and the possibilities of automation can be enhanced. Additionally this will lead to a much better success to the rear end of the tractor and to more flexibility to connect various attachments. So electro-hydraulic operated systems have a lot of advantages.
