Yanmar Company

Yanmar Co., Ltd. is a Japanese diesel engine manufacturer founded in Osaka, Japan in 1912.

Yanmar manufactures and sells engines used in a wide range of applications, including seagoing vessels, pleasure boats, construction equipment, agricultural equipment, and generator sets.

It also manufactures and sells agricultural equipment, construction equipment, climate control systems, aquafarming systems, in addition to providing a range of remote monitoring services.


When Yanmar began in 1912, it manufactured gasoline-powered engines.

In 1920, the company began production of a small kerosene engine.

In 1933, it launched the world's first practical small diesel engine, the HB model.

Yanmar also supplies engines to John Deere tractors and for some Thermo King Corporation coolers used in refrigerated trucks and trailers.

In 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.

"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.


1912 --- Yamaoka Magokichi sets up business under the name Yamaoka Hatsudoki Seisakusho (Yamaoka Engine Workshop).

1933 --- Production of world's first practical small diesel.

1992 --- The company produces its 10 millionth diesel engine.

2015 --- Yanmar acquired 70% of Spanish generator-set manufacturer HIMOINSA.

2016 --- Yanmar increased its stake in the Indian company International Tractors, the maker of Sonalika branded tractors, to 30%. The company also bought German compact equipment maker Schaeff and forged a partnership with Toyota to develop “next generation hulls” for boats.
