In the vast area of arable land, in order to support high-power tractors, the development of high-speed, wide-width, efficient machinery, while avoiding the whole unit overweight, causing the accumulation of deep land compaction; In areas with small plots or on sloping land, soil farming machinery is still mainly small. In the structure, the use of low pressure tires and electronic and hydraulic components; In the development and design of working parts, attention should be paid to the use of the characteristics of low tensile strength of soil, and the combination of biological tillage and chemical tillage to improve the ecosystem in soil and the ecological environment of the whole agriculture.
