The agricultural machinery hybrid powertrain assembly includes 6 agricultural machinery hybrid powertrain systems with power ranging from 50 horsepower to 600 horsepower. The second is the new tractor products released by Shandong Lingong, which respectively use a full range of new energy power technologies such as electric transmission and mechanical transmission coupling continuously variable transmission, series hybrid continuously variable transmission, hydraulic and mechanical coupling continuously variable transmission. In addition, at the International Agricultural Machinery Exhibition held in Changsha in 2024, many large and medium-sized tractor companies exhibited hybrid new energy heavy-duty tractors. The 260-horsepower pure electric tractor of Zhongke Yuandongli was unveiled, which is also the pure electric tractor with the largest power in my country.
This shows that in addition to breakthroughs in power shifting and continuously variable transmission, my country’s heavy-duty tractors have also launched a number of new energy hybrid tractor products, opening up a new energy power track for heavy-duty tractors. This also indicates that the research and development of new energy tractors in 2025 will be multi-pronged.The reason for the multi-line research and development is that new products like new energy tractors cannot be achieved overnight, nor can they be put on the market in large quantities in the short term. There needs to be a maturation process of research and development, verification, improvement, and re-verification, which takes at least three to five years and at most seven to eight years. Therefore, in 2025, I personally think that hybrid new energy heavy-duty tractors can only be developed in multiple lines, and it will take some time to enter the market.
In terms of categories, my country’s new energy tractors currently mainly include pure electric tractors, hydrogen fuel cell tractors and hybrid tractors. At present, these three types of tractors are in the process of research and development in my country.
Judging from the new hybrid heavy-duty tractor products currently released, there are two main power transmission methods: one is hybrid power + continuously variable transmission, and the other is hybrid power + wheel-side motor drive.
We have already introduced the working principle of hybrid power + continuously variable transmission, and the hybrid power + wheel-side motor drive is a bold innovation in tractors. If it succeeds, it will omit the mechanical transmission of the tractor, and the wheels can be driven directly by the power battery, or the diesel engine can be used to drive the engine to generate electricity, and then the wheel-side motor can be driven by electricity to make the tractor move. The tractor speed change only needs to control the speed of the wheel-side motor. What power shifting, what continuously variable transmission, all are not needed, only the wheel-side motor and its control technology are needed. It is conceivable that if this technology in China succeeds, and wheel-side drive tractors are commercialized and put on the market in batches, what kind of market situation will it be!
