New Product - Electric Autonomous Driving Tractor
Industry background
During the 13th Five Year Plan period, agricultural machinery will develop comprehensively, and the mechanization rate of crop cultivation and harvesting in China will reach 71.25%. Intelligence and green will become the development themes of the 14th Five Year Plan; The level of tractor and agricultural machinery equipment industry is not high, and high-end supporting equipment relies on imports. Domestic products are mostly mid to low end products, with overcapacity and serious homogenization. The reliability and adaptability urgently need to be improved. After 10 years of development, the monthly penetration rate of new energy vehicles and tractors has exceeded 30%, providing a good industrial supporting foundation.
Policy guidance
On May 18, 2022, the Ministry of Industry and Information Technology released the "Roadmap for Intelligent Agricultural Machinery Technology"
China has released its first intelligent tractor and agricultural machinery technology roadmap, based on unmanned agricultural machinery as the final product form, proposing nine cutting-edge and key technologies including agile whole machine architecture, universal digital chassis, new power system, integrated work tools, and new energy system;
On January 24, 2022, the State Council issued the Comprehensive Work Plan for Energy Conservation and Emission Reduction during the 14th Five Year Plan period
Agricultural and Rural Energy Conservation and Emission Reduction Project - Promote the application of agricultural electric vehicles, electric tractors, energy-saving and environmentally friendly agricultural machinery, and fishing boats, develop energy-saving agricultural greenhouses, promote energy-saving renovations of farmhouses, and build green farmhouses;
December 27, 2021, Ministry of Agriculture and Rural Affairs, "14th Five Year Plan for National Agricultural Mechanization Development":
Accelerate the intelligent and green development of agricultural machinery and tractors, promote the integrated application of technologies such as Beidou automatic navigation, high-pressure common rail, power shifting, continuously variable transmission, new energy power, and electromechanical hydraulic integration in agricultural machinery and equipment, develop compound and efficient agricultural machinery and agricultural machinery electric equipment according to local conditions, and reduce exhaust emissions.
New energy product - pure electric tractor
In 2021, the company initiated the research and development of a new energy electric tractor for facility horticulture. This product is aimed at the modern vegetable greenhouse and orchard markets, and can significantly improve the working environment and operator comfort, significantly reduce usage costs, and improve crop quality. It is also the first pure electric agricultural machinery product in China to enter the practical stage.
In May 2024, the company re initiated the small-scale development of electric tractors.
