The main task of the rollers is to suppress the soil. They are used to crush the cutters that cannot be broken by soil tillage tools and to correct the surface of the field. The rollers can be inserted into the field before and after planting. By sowing before planting, it breaks down the cuttings of the processed field and presses the soil and provides a balance between the air pockets, the water-to-air ratio of the soil is arranged and a good seed bed is prepared. After sowing, it helps to increase the relationship of the seeds with the soil and to bring the water in the lower floors closer to the area where the seeds are located.
