"Green Iron Ox": Methanol Autonomous Tractor（Sep 17）
"Green Iron Ox" on the Black Soil: Methanol Range-Extender Electric Autonomous Tractor
On a demonstration field in Baoqing County, Shuangyashan City, Heilongjiang Province, a cab-less "iron ox" advances steadily along a straight line, turning up dark soil behind it. This is the methanol range-extender electric unmanned tractor developed by Heilongjiang Ruiyi Technology.
The tractor is equipped with Beidou high-precision navigation, achieving centimeter-level positioning and precise row spacing control. Methanol refueling takes only 3 minutes, enabling 24-hour continuous operation. Instead of burning diesel, it runs on methanol, reducing fuel costs by over 30% compared to traditional diesel tractors and cutting carbon emissions by over 80%, with zero field pollution.
The unmanned driving system brings practical benefits. Beidou high-precision positioning enables centimeter-level inter-row spacing control, avoiding repeated soil compaction and protecting soil structure. The tractor can operate 24 hours without a driver, helping address labor shortages and high labor costs during peak farming seasons.
Compared with imported high-end smart tractors, the product is priced at approximately half, with lower maintenance costs and faster local service response. Operators can be trained in just one to two days. A production base with a total investment of 770 million yuan is under construction in Bayan County, with planned capacity of nearly 1,000 units upon completion.
The company's product matrix also includes a methanol range-extender plant protection drone, capable of 6 to 7 hours of endurance per methanol refill. Going forward, the company plans to build a circular industry chain of "straw - green methanol - low-carbon farm machinery," promoting straw resource utilization and providing low-cost green fuel for farmers.
