The evolution of the agricultural mechanization has transformed the tractor from a simple tractive device into a more sophisticated machine to be matched with a wide variety of specific implements.
The part allowing the control of the implement position and therefore its proper operation is the hitch lifting system.
To increase the accuracy and the functionality of this system, up to now hydraulically or mechanically driven, and to reduce also the installation, adjustment and operating problems an electronically controlled system has been developed.
The electronic system is based on a microprocessor unit which either provides to elaborate the signals supplied by suitable position and tractive force sensors and to fulfil, on the base of pre-set strategies, the operator requirements by means of proper actuators.
Moreover the electronic unit can, at the same time, display to the operator the working parameter of the implement.
