This innovation has changed the traditional farming method, integrated a crawler-type walking system with low grounding pressure and good farming effect, and connected it with a rotary cultivator with strong versatility. The combination of the three makes the machine not only have excellent walking function, but also have good farming effect. Independent transfer case output system and standard three-point suspension are adopted, which can be used for universality and mutual matching of various farm tools and improve the adaptability of farm tools.
(2) The unique design and manufacture of the track underframe.
Strengthen the design structure, with a rake angle of 30 and a rake angle of 45, which greatly improves the passing performance of climbing and retrogression. The optimized underframe improves the strength of underframe. The chassis of the crawler is 200MM higher than that of the harvester, which increases the anti-sinking performance of the machine and makes the machine walk freely in the deep muddy paddy field.
(3) rotary cultivator cutter and grass winding prevention device
Rotary cultivator adopts IS 175 paddy field rotary cultivator, which has the characteristics of low power consumption and good cutting effect. At the same time, an anti-grass-winding device is adopted, which has the function of preventing grass-winding, reducing power consumption and improving breeding efficiency. The device enables the primary tillage to achieve the effect of traditional mechanical secondary tillage, which not only improves the efficiency, but also improves the flatness of the field, reduces the operation intensity and saves the cultivation cost.
(4) Reasonable distribution of walking speed and cutting speed of rotary cultivator.
This innovation makes the machine have a variety of cutting speed ratios. The high cutting speed ratio can be used in dry farming, so that the broken soil rate of cultivated land can reach 80%, far higher than the national standard of 60%, while the low cutting speed ratio is used in paddy farming, which not only improves the farming speed, but also makes the field meet the planting requirements.
(5) Selection of forward speed
The selection principle of the forward speed of the rotary cultivator is to meet the requirements of breaking soil and leveling the bottom of the ditch, that is, to ensure the farming quality, give full play to the power of the tractor, and achieve the purpose of high efficiency, high quality and low consumption. In general, the forward speed of rotary tillage is 8 km/h.

Market competitiveness and development prospects;
Agricultural mechanization in China presents a steady development trend. China's agricultural machinery market demand is strong, and the area of cultivated land harvested by machinery is increasing year by year, which makes some high-performance rotary tillage machinery favored by the market. In the process of promoting agricultural modernization, the government has successively introduced encouraging policies and measures to support farmers in purchasing agricultural machinery and developing agricultural machinery operation services, such as implementing agricultural machinery subsidies, which greatly mobilized farmers' enthusiasm for purchasing agricultural machinery, thus stimulating the growing demand in agricultural machinery market.
With the adjustment of China's rural industrial structure and the improvement of economic development level, farmers' employment plans and incomes are increasing, and some farmers have strong economic payment ability, so the desire to realize agricultural production mechanization is more urgent. A 57,000 yuan rotary tiller can be bought by ordinary farmers or 2-3 households in partnership. Besides self-farming, they can also buy machines for profitable agricultural services. Rotary cultivators are used for a long time, and the seasonal requirements are not as strong as harvesters. From spring ploughing to winter ploughing in a year, at least 1 1,000 mu of cultivated land can be cultivated, and the average cost per mu of cultivated land is about 1 1,000 yuan, and the gross income reaches 65,438 yuan. Because farmers can afford it, use it and use it, the market demand has been growing. If a rotary cultivator cultivates 30-40 mu of land every day, it can cultivate about 900- 1200 mu in about 30 days a year. For example, the rice planting area in Changde area is 7,682,300 mu, and 7,000 rotary cultivators are needed. The rice planting area in Hunan Province is more than 60 million mu, and more than 60,000 rotary cultivators are needed. Similarly, the demand for crawler-type self-propelled rotary cultivators in Jiangnan provinces is similar to that in Hunan, and the demand for crawler-type self-propelled rotary cultivators in northeast rice producing areas is even greater. At present, the annual sales volume of agricultural machinery in China is 8 million, including nearly 5 million cultivators. Crawler-type self-propelled rotary cultivator can replace most traditional tillage machinery and compete with it.
