[ China Agricultural Machinery Industry News ] According to the report of the Agricultural Machinery Guide, the United States has developed a 400-horsepower pure electric tractor. The tractor is equipped with two independent 150KW electric motors, which can run for 4 hours on a single charge. Many attempts have been made at home and abroad.
The high attention is about the John Deere SESAM electric tractor.

At the 2017 SIMA show in France, John Deere officially released SESAM, a pure electric tractor that has been developed for many years.
SESAM is an improved 6R classic series tractor from the Mannheim plant in Germany, with a power of 360 hp (260 kW). The first generation is equipped with two batteries, each providing 130 kW of power. One of them is for walking and the other is for PTO. If necessary, two batteries can be connected to provide more power.
SESAM can last up to 4 hours of work time or 55km of transport time. The charging time is 3 hours and the battery life is 3100 times rechargeable. Due to its electric drive, SESAM's low-speed torque is particularly large, and with the infinitely variable speed, the peak power can reach 400 hp.
In China, there are also companies that research electric tractors. As early as 2011, Haibo Reid (Beijing) Automotive Technology Co., Ltd. developed a prototype of electric tractors and conducted a live demonstration in Sanmenxia City. The total weight of the machine is 3995 kg, and the battery is full. After the electricity, you can run for 30 kilometers. If you plow the ground and the total weight is 1150 kg, you can run for 3 hours and plow 2 mu of land when fully charged. The high speed is 30 kilometers per hour when there is no load.
The development of electric agricultural machinery is inseparable from policy support. The major domestic influence should be the introduction of policies in Shanxi Province to support the development of electric agricultural machinery industry. The government will provide 50 million yuan each year to subsidize electric agricultural machinery, and 20 counties will be compensated for by awards. In the pilot counties, Shanxi Province is the first to open electric farm machinery subsidies, which is indeed worthy of admiration.
According to the author's observation, when talking about electric agricultural machinery, everyone first think of electric tractors. Most of the enterprises that want to try to make electric agricultural machinery start from electric tractors. Because tractors are the power source of agricultural machinery, the demand is large, the technology is mature, and the fuel is used. The electricization of tractors is low in difficulty, low in cost and easy to get started.
However, this view may be wrong. When the reporter recently interviewed the boss of Liu, a farm machinery manufacturing company in the north, he expressed a completely different view.
