According to the present situation of the farmland levelling, the equipment cost is high, maintenance is complex and its cost is high. The paper carries a research on the key technology of self-propelled farmland levelling machine. The key technology includes the levelling knife, the levelling part, the sundry separating device and the measurement and control system of the laser and inclination sensor. At the same time, the paper establishes the hydraulic servo system mathematical modal and utilizes MATLAB to analyse, revise and simulate for the system mathematical modal.
