Driving force, driving resistance and operating resistance of wheeled combine harvester during operating process was analyzed, tire model, road model as well as force model was built, numerical simulation of motion for whole wheeled combine harvester was finished and attitude curve was obtained. Lifelike virtual scene including terrestrial surface environment, such as farm field, roads, trees, grassland, etc. was created. Visual model of wheeled combine harvester after reasonable simplified was imported to visual simulation driving platform, and interacting control of whole machine attitude in visual scene was put forward, which made visual simulation more realistic. This study laid the foundation of building interacting control integrated virtual testing platform for combine harvester. 
