Abstract: In the harvesting operation, the stubble height of the grain is an important parameter index in the combine harvesting operation, the stubble is too high or too low will directly affect the harvesting quality and the service life of the cutting table. At present, the profiling control system can only control the lift of the cutting table in the vertical direction, but not the horizontal direction and the angle of the cutter profiling. The purpose of this study is to propose a contouring control strategy and system for grain harvesting by analyzing the designed contouring adjustment mechanism, and to simulate the control method and hydraulic system through Amesim software to simulate and analyze the control method and hydraulic system. Finally, different forward speeds of the harvester (5、7、9、11km/h) and different cutting heights of the harvester were analyzed based on static and field tests and different stubble heights (100、150、200、250mm) on the test indexes. The results of the field test showed that for different operating speeds, the error between the mean value of stubble height and the target value was small, and the absolute error was less than 2mm, the mean value of the coefficient of variation of stubble height was 4.53% and the mean value of control accuracy is 94%.The developed adaptive control system of the profiled grain cutting deck has high accuracy and stability, which can provide reference for the all-terrain profiling control technology of combine harvester cutting deck.
