The paper carries a research on the self-propelled farmland levelling machine that not only can level the soil surface but also collect the sundries and designs soil-sundry levelling and collecting device, soil- sundry separating device and levelling control system based on laser and inclination sensor. The hydraulical motor drives the leveling and collecting knife shaft rotate to collect the sundries and roughly level the surface. The separating device separates the sundries and the broken soil through the vibration. The levelling control system adopts inclination sensor and laser emitter as the datum signal to form the datum plane. The hydraulic servo system controls the levelling device to work on the plane that parallels with the datum plane. At the same time, the paper establishes the hydraulic servo system mathematical modal and utilizes MATLAB to analyze, revise and simulate for the system mathematical modal. The test result shows that self-propelled farmland levelling machine is satisfied with the levelling request.
