10+ years of specialized manufacturing in agricultural machinery aftermarket parts — CE & ISO 9001 certified factory in Yancheng, China
Orisun Machinery Co., Ltd. was founded in 2013 in Yancheng, Jiangsu Province — one of China's premier agricultural equipment manufacturing zones. We began with a singular mission: to provide farmers, dealers, and repair workshops around the world with reliable, affordable, and precision-engineered aftermarket parts for top agricultural brands.
Over the past decade, we have grown from a small workshop to a fully integrated manufacturing facility with 50,000m² of production space, 200+ skilled engineers and workers, and an export footprint spanning 50+ countries across North America, South America, Europe, Australia, and Southeast Asia.
We specialize exclusively in aftermarket replacement parts for John Deere, Case IH, and CLAAS agricultural machinery — including combine harvesters, tractors, headers, forage harvesters, and self-propelled sprayers. Our product range covers 10,000+ SKUs across belt pulleys, clutches, sensors, belts, gears, hydraulic assemblies, electrical components, and wear parts.
