The development direction of rotary cultivators

1. Development of wide-width high-speed rotary cultivators. With the development of intensive and large-scale production of rice, wide-scale rotary cultivators for paddy field ploughing and land preparation will become the development direction.

2. Develop in the direction of joint operation unit. Large and medium-sized tractors have a strong power output system, traction and suspension capacity, which provides conditions for supporting dryland combined tillage machinery. As a driven tillage machine, the rotary cultivator is easy to complete the combined operations of stubble extermination, deep loosening, broken soil, furrowing, ridge raising, trenching, precision or semi-fine sowing, deep fertilization, film laying, suppression and spraying through the replacement or additional working parts, which can greatly improve production efficiency and reduce operating costs. Foreign developed countries have promoted the use of joint operation units with the combination of operation processes and rotary tillers as the main body, such as Canada's universal rotary tillers, Japan's joint tillage rake ploughs and rotary tillage seeders.

3. Develop strategically towards sustainable development. Reducing pollution and resource reuse has become the ultimate goal of the current agricultural mechanization design, and new models such as the reverse stubble extermination rotary cultivator that can complete the straw return operation will become an important research direction of rotary tillage machinery in the future. In addition, with the rapid development of modern science and technology, some new technologies will also be widely used in rotary tillers, such as signal systems.

4. The demand for small rotary cultivators has increased. With the development of greenhouse technology in China, the cultivated area of rural greenhouses is increasing, and due to the demand of the market, small rotary tillage machinery suitable for greenhouse operation has become a new focus of research.
