Promoting the high-quality development of the agricultural machinery and equipment industry is related to food security and the construction of an agricultural power. The core components of domestic agricultural machinery are influenced by factors such as materials and technology, and there is a significant gap between them and imported components. Many large grain farmers report a high failure rate of domestically produced agricultural machinery, which often affects the progress of cultivation. What is the gap in domestic agricultural machinery? How can we catch up with the international advanced level?
During the preparation season, farmers from the Luwei Agricultural Machinery Farmers' Professional Cooperative in Lishu County, Jilin Province are busy repairing tractors, harvesters, seeders and other agricultural machinery. The head of the cooperative, Lu Wei, pointed to a large harvester and said that this domestically produced harvester needs to be repaired every few days of work in the field, while the imported large harvester needs to be repaired once a year.
The consensus among some grain growers is that domestic agricultural machinery is cheap but not resistant to manufacturing. Some domestic brands of agricultural machinery have high failure rates, such as gearboxes, rear axles, and hydraulic systems. During the operating season, they undergo minor repairs every 3 days and major repairs every 5 days, resulting in high annual maintenance costs for agricultural machinery. Zhang Shuai, a major grain grower in Siping City, Jilin Province, said, "Some domestically produced large harvesters are overhauled once a year, which costs over 10000 yuan.
It is understood that some domestically produced agricultural machinery fails in the field and delays work, which is related to factors such as the rationality of the internal structure of agricultural machinery and the quality of components. Jin Yingmin, a major grain grower in Qian'an County, Jilin Province, has replaced several no-tillage seeders in recent years. He said, "Basically, it takes three years to replace them with new ones. The old ones have a high failure rate, which delays work, so why not fix them.
