An attitude adjustable land leveling equipment was designed. The reference elevation of the land to be leveled was generated based on the topographic data which was acquired by the RTK-GNSS technology. The blade lifting mechanism was controlled by comparing the reference elevation and the real-time blade’s elevation and attitude data which was obtained by the dual antenna GNSS receiver and as a result the land leveling operation was implemented. A new algorithm using the electro-hydraulic proportional control technology which can control the blade’s height accurately was also raised. The experiment shows that the GNSS land leveling equipment can have a good land leveling quality, and the efficiency of the land leveling operation could also be improved.
