The leveling arc plate can be turned over by rotating 180°, which is convenient for the grader to level the ground back and forth. When the leveling arc plate rotates to an inclined position, it can play a guiding role, guiding the excess soil to be removed and piled up, which is convenient for subsequent leveling work.
