The deep loose laser grader is a farming machine used with high-horsepower tractors. It is mainly used for the mechanization of soil cultivation between rows. In addition to all the functions of ordinary laser graders, It also has deep loosening functions, which is conducive to improving the structure of the soil plough layer, breaking the bottom of the plow, improving the water storage and moisturizing ability of the soil, and promoting grain growth.
