The Shanghai disc plow is fully suspended and matched with tractors. During operation, the plow blades rotate and move to plow the soil. It has the advantages of not entangling grass, not blocking, not allowing soil to settle, being able to cut off crop stems and roots, and having lower working resistance compared to a plow. It is particularly suitable for farmland operations with complex conditions such as overgrown weeds, numerous stems, high soil resistance, and the presence of broken bricks and stones in the soil.
