Kubota Corporation was founded in 1890 in Osaka, Japan.

The initial specialization of the company was the production of cast-iron pipes for water pipes.

Then, in 1920, the company launched the production of internal combustion engines, which found their main application in agriculture. Also, more powerful diesel engines were intended for agricultural machines, the production of which was mastered in the 30s.

Gradually, the production of engines became the main specialization of the company; Kubota Corporation engines are also used in Wilson generators. In 1972, the first foreign representative office of the company was opened in Indonesia. Since then, Kubota Corporation products are sold in more than 130 countries.

Now Kubota Corporation is an international leader in three product groups: internal combustion (incl. marine) engines, industrial products, building materials.

In 1987, the release of the 10 millionth engine was recorded, and already in 2003 this number was doubled.

The scale of production on the example of other products is also evidenced by the fact that more than 50,000 mini excavators and other compact construction equipment by Kubota Corporation are currently sold worldwide.

Engines were added to Kubota's numerous product line in 1922 when we researched and developed the agriculture and industry engine Type A, with 3 horsepower. Our engines were then expanded for various usages, and engines of high output, compact and lightweight, have gained a high level of trust in the global market.
We are one of the world's top-class manufacturers of compact diesel engines, also being famous for being the first manufacturer to pass the U.S. CARB ULGE* emission regulations for engines under 19 kW (25 HP). To meet the needs required for a wide variety of industrial engines, we have made the spotless output assortment of up to 86.4kW, running on various fuels as such diesel and gasoline · LPG · Natural gas on the same platform.
On top of our seamless product line-up, we have now extended our product range up to 157.3 kW with the Kubota 09 Series to meet customers diversified needs.
The greatest advantage of Kubota engine is the technology to respond to environmental requirements and application engineering. Since receiving the CARB certification of emission regulations (California Air Resources Board, USA) for the first time in the world as small industrial engines in 1993, we have always conformed to strict emission controls from around the world as a pioneer of environmental technology.
Today, we are expanding our production activities to optimal locations to supply engines to global equipment manufacturers in a timely manner. From 2014, we started the production in China in addition to Thailand where our integrated production covers the entire process, from the manufacturing of casting materials to engine casting and assembly. We will keep striving to deliver Kubota quality all over the world.

• Delivering Engines Meets World Wide Emission Regulation

  As the awareness for the conservation of the global environment has increased, emission standards for industrial engines have become more stringent. All industrial equipment manufacturers are now required to use emission certified engines. In this circumstance, as a leading industrial engine manufacturer, Kubota has always developed the engine which meets emission regulations across the world. Kubota also offers a full line-up of compact diesel engines from 56kW to 86.4kW which meet EPA/CARB Tier 4 (including Tier 4 Final) and EU Stage IV standards.

• High Quality Based on Casting Technology

  Kubota was founded in 1890 with casting business. The casting technology is one of our core technologies for various products including engines. With the casting technology, Kubota can produce complex shaped crankcase which keeps our engines with high-performance and high-durability.

• Delivering Kubota's Reliability Even to Bigger Range

  In 2016, Kubota announced development of its first large-displacement engine, Kubota V5009. With its good balance between reliability, performances and high power density, this engine was awarded to “Diesel Of The Year 2019” as the first Japanese winner.
