12PJZ series self-balancing laser grader can use dual receiver or single receiver to receive. When receiving with single receiver, it can be used as an ordinary grader. When double receiving, it can automatically control the flat shovel to always maintain a relative angle with the ground, which can protect the entire The plot has no slope. The corners of the entire field are free of dead corners, and the entire field can be absolutely horizontal or relatively horizontal.
