This invention relates to the field of land consolidation and development technology, and in particular to a land leveling device and method with adjustable functions. The leveling method involves first determining a reference horizontal plane, then dividing the farmland into m*n blocks. The bucket passes through n rows of farmland sequentially along a first direction, recording the distances h1 to hn between the reference horizontal plane and the blade. Based on the data h1 to hn, the average distance h between the blade and the reference horizontal plane when in n rows of farmland is obtained. Δh is measured based on the soil volume in the bucket and the farmland area. (h-Δh) is the distance between the target leveling surface and the reference horizontal plane. The bucket height is adjusted to maintain the distance (h-Δh) between the blade and the reference horizontal plane. The process continues along a second direction, passing through m rows of farmland sequentially, completing the farmland leveling. The leveling method provided by this invention facilitates the determination of the target leveling surface and is more conducive to agricultural cultivation and irrigation drainage.
