Abstract: In order to solve problems of singular teaching form for tractor structure and theory courses at agricultural universities, high difficulty and risk associated with tractor driving practice training, a tractor driving simulation system used for dynamic simulation and driving training capabilities was designed based on Unity3D virtual simulation platform．Firstly, hardware environment was built based on LF2204 high power tractor cab．Secondly, data acquisition system was designed and driving simulation software was developed featuring an 7 degrees of freedom tractor dynamics model．Finally, thirty students majoring in agricultural mechanization participated in practical training, and questionnaires were used to evaluate teaching effectiveness．Rresults showed that system effectively promoted students' understanding and practice ability of tractor dynamics theory and helped students improve their tractor driving ability．System has provided a new platform and tool for improving teaching quality of practical training in agricultural machinery-related majors at agricultural universities．
