Abstract: An electro-hydraulic hitch system was designed， with rational space layout and simple structure， and some aspects of the system in terms of constitution， working principles were presented and force-position regulation control strategies were proposed. The system can achieve hitch force and position control by ECU considering farming situation， while a force-position regulatory feedback was achieved based on fuzzy control. The bench test showed that the fuzzy controller could satisfy the requirement of force-position regulation.

Key words: electro-hydraulic hitch system, force-position adjustment, fuzzy control
