Recently, the first Dongfanghong 220-horsepower hybrid tractor developed by YTO, the HB2204, was successfully rolled off the production line and is expected to be put on the market in small batches in 2023.

It is reported that the Dongfanghong HB2204 hybrid wheeled tractor is based on the compound agricultural machinery hybrid system independently developed by China YTO, and adopts its self-developed high-efficiency energy management system and intelligent electric drive speed control unit. Compared with the traditional power tractor, the high pressure common rail engine has the following three advantages.

First, the electric drive continuously variable transmission system is adopted, which can realize 0~40km/h continuously variable speed driving. It has the characteristics of continuous speed ratio, simple structure, high transmission efficiency, high reliability, fast power response and large torque reserve.

The second is that the engine is at the best economic point or the best power point, which is efficient and fuel-saving; it is suitable for occasions with high requirements for speed control, load change, comfort and economy, and has strong adaptability.

The third is that the pure electric mode can meet the needs of transition, land and light-load operations; the whole machine is simple and comfortable to operate, and the operation intensity is low; the electronic intelligent management system controls the engine speed and motor speed, including self-diagnosis and alarm system.

The unique advantages make it capable of field operation, road transportation and other modes, and can realize joint and precise operation with other agricultural machinery. It is suitable for field operations such as deep ploughing, deep loosening, and joint land preparation in large farms at home and abroad. It mainly meets the requirements of tractor emission cleanliness and precise control. Farm operation requirements with high flexibility and comfort.

According to reports, the HB2204 hybrid wheeled tractor is one of the key tasks of my country YTO to build the source of original technology in the field of agricultural machinery and one of the phased achievements of the State Key Laboratory of Tractor Power Systems, and its localization rate has reached more than 85%. . At present, functional debugging has been completed, and application verification is being carried out, laying the foundation for subsequent mass production.
