The deep plowing plow is a fully suspended operation, which includes one-way suspension and pneumatic (hydraulic) flipping, and is used for cultivating mature land in areas such as loam and sandy soil. It has a simple structure, a flat surface after tillage, and good soil thinning performance. When tilling back and forth, the soil always turns to one side without leaving any soil moisture ditches in the ground. Due to the fact that the soil always turns to one side during tillage back and forth, it has the effect of reducing slope and leveling when tilling mountain slopes and sloping land.
