Learn About the Yanmar Engine
Since Yanmar first began providing engines to customers in Japan in 1912, we’ve grown to become a recognized leader in the design and manufacturing of advanced performance diesel engines and diesel-powered equipment, as well as gas engine-based energy systems. With more than 110 years of history, we’ve continued to refine our machines and have developed a reputation among tractor owners for some of the very best engines in the industry.
Whether you already own a Yanmar tractor or are trying to decide which model is right for you, read on to learn about what makes the Yanmar engine a high-performance, industry leader.
The First Yanmar Engines
The inspiration behind the first Yanmar engines was to make work easier for farmers and laborers through reliable, compact, and efficient engines. This resulted in a three-horsepower vertical oil-powered engine, followed by a horizontal oil-powered engine. As usage and word spread about Yanmar’s engines, the response was overwhelming.
With demand high, the company continued to innovate, working to create an even smaller, more effective diesel engine. In 1933, there was a breakthrough when the prototype of this design was successfully tested after many iterations. The resulting product was called the HB Model.
Applications of the Yanmar Engine
Over the years, Yanmar has produced more than 15 million diesel and gas engines ranging from 4.5 to 5,000 horsepower. While tractors are one of the most widely known applications, our engines are popular for a number of different uses, including:
- Commercial and recreational marine
- Utility task vehicles
- Industrial equipment
- Energy systems
Yanmar Tractor Diesel Engines
When your tractor is powered by a Yanmar diesel engine, you get the added benefit of knowing you’re working more effectively and efficiently. Our machines utilize some of the most advanced technologies in the industry, allowing you to experience the Yanmar difference.
At the core of every tractor is the liquid-cooled diesel engine. Our sub-compact tractors such as the SA Series are equipped with a 3-cylinder engine, while larger tractors like the YT3 Series are equipped with a 4-cylinder engine.
No matter which engine you’re operating, our innovative fuel-injection systems and combustion chambers create an outstanding level of power to help tackle the toughest jobs. On top of that, the efficiency of the Yanmar diesel engine provides a smoother ride, reduced emissions, and greater fuel economy.
One of the most critical components that sets the Yanmar engine apart is the integrated Hydro Mechanical Transmission (i-HMT). This versatile feature comes with numerous benefits to the operator, such as:
- Step-less and clutch-less shifting from zero to maximum speed
- Ability to control ground speed and engine speed with AB mode
- Auto throttle to control engine and travel speed with accelerator/drive pedal
- Brake and stop the tractor without engaging the clutch
- Conversion of horsepower into PTO horsepower and drawbar horsepower
- Anti-stall capabilities
- Cruise control
Performance Link Technology
Another invaluable aspect of Yanmar engines is known as Performance Link Technology. This means we produce all major drivetrain components in-house – the engine, transmission, front axle, and final drive components – so each piece works perfectly in conjunction. We believe in this quality so strongly we back it with an industry-leading, 10-year limited powertrain warranty.
Yanmar UTV Engines
When you have a large property, the ideal complement to your Yanmar tractor is one of our rugged and powerful UTVs. There are options to meet every need and preference, with the diesel-powered Brahma Series and the gas-powered Bull and Longhorn models. Every Yanmar UTV is equipped with features like 4WD, electric power steering, and a heavy-duty hitch.
Yanmar Green Initiatives
Though Yanmar engines deliver exceptional performance, they’re also designed with the environment in mind. Our technology already meets the next generation of emissions standards, and we continue to seek the most sustainable solutions through the Yanmar Green Challenge 2050. We’re dedicated to the goal of reducing greenhouse gas emissions from all of our products to make them fully green by the year 2050.
