Company descriptionEdit

Yanmar Corporate Headquarters (Japan)

Yanmar was founded in March 1912 in Osaka Japan[2] by Magokichi Yamaoka.[3][4]

When the company began in 1912, it manufactured gasoline-powered engines.[5] In 1920 the company began production of a small kerosene engine.[6] In 1933, it launched the world's first practical small diesel engine, the HB model.[5][7][8]

Yanmar also supplies engines to John Deere tractors[9] and for some Thermo King Corporation coolers used in refrigerated trucks and trailers.[10] 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 primarily used in agricultural spraying and other forms of aerial application.[11][12]

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."[13]
