Company description[edit]

Yanmar Corporate Headquarters (Japan)

Yanmar was founded in March 1912 in Osaka Japan[1] by Magokichi Yamaoka.[2][3]

The company specializes in diesel engines, and also makes light fishing boats, hulls for ships, tractors, combine harvesters, rice-planting machines, gas heat pumps, snow throwers, transporters, tillers, mini excavators, portable diesel generators Side by Side UTV and Heavy Utility Machinery. When the company began in 1907, it manufactured gasoline-powered engines before switching to diesel in 1920.

Yanmar was the first to put a diesel engine in a rice planting machine with a passenger seat. Yanmar also supplies engines to John Deere tractors and Thermo King Corporation used in refrigerated trucks and trailers. Within the last 20 years, Yanmar has also established a growing presence in the domestic UAV market in Japan and elsewhere, with small helicopter UAVs such as the Yanmar YH300 SL and Yanmar AYH-3, primarily used in agricultural spraying and other forms of aerial application.

Yanmar is the patron of the J. League Division 1 soccer team Cerezo Osaka and sponsor for AFC Champions League, Yanmar Racing and several weather forecast programmes on Japanese television. They sponsor a German football club Borussia Dortmund and also are a global sponsor to Manchester United F.C..

As described on the company website, "The name [Yanmar] is a combination of the Yanma Dragonfly (known by names such as Oniyanma and Ginyanma) and the "Yama" from the name of the company founder Magokichi Yamaoka."[4]
