[0002] Forage grass has strong regeneration ability, can be harvested many times a year, and is rich in various trace elements and vitamins. Therefore, it has become the first choice for raising livestock. The quality of forage grass varieties directly affects the economic benefits of animal husbandry and needs to be paid attention to. During the planting process, forage grass generally needs to be turned over by a soil turning device. At present, in the existing forage grass planting and management process, soil turning is a crucial link, which is directly related to the growth environment, soil fertility and yield of forage grass. In flat and open areas, large agricultural machinery has become the preferred tool for soil turning operations due to its high efficiency and speed; these machines can quickly and deeply turn the soil, break the soil compaction, promote the activity of microorganisms in the soil, and provide good soil conditions for the growth of forage grass. However, with the continuous development and popularization of forage grass breeding industry, more and more forage grass is planted on complex terrains such as mountains and hills. Due to the undulating terrain and rugged ground in these areas, large agricultural machinery is often difficult to enter or cannot operate effectively. In this case, if manual tillage is relied upon, although the problem of machinery being unable to enter can be solved to a certain extent, the efficiency is extremely low and the labor cost is high. Manual tillage is not only time-consuming and labor-intensive, but it is also difficult to ensure the depth and uniformity of tillage, thereby affecting the growth quality and yield of forage grass.
