For decades, Kubota has set the standard in industrial engine design – and the WG Series continues that legacy with spark-ignited (SI) engines engineered for today’s fuel-flexible, high-performance applications. Developed from Kubota’s trusted diesel platforms, the WG Series offers a seamless transition to spark-ignited power without compromising durability, performance or footprint compatibility.
At the heart of the WG Series is a lineup of engines that run on gasoline, propane, LPG or natural gas – including models capable of switching between fuel types. Whether your machines require dual-fuel capability or single-fuel efficiency, the WG Series delivers powerful solutions with the same reliability and footprint you expect from Kubota.
Fuel flexibility and simplified integration
Purpose-built for industrial use, the WG Series is designed with plug-and-play simplicity in mind. OEMs benefit from consistent engine dimensions across models, easing integration across platforms while supporting a wide range of horsepower to meet varying design needs.
The perfect fit for countless applications
Designed to serve a wide range of industries and equipment types, the WG Series offers a go-to solution for manufacturers seeking flexible fuel options and long-term reliability. Typical applications include:
- Forklifts
- Aerial Work Platforms
- Ground Support Equipment
- Turf Equipment
- Generators
- Ground Heaters
- Oil and Gas Applications
- Hybrid and Alternate Fuel Equipment
Don’t see your application listed above? Bring your ideas to us! These engines are as adaptable as the fuel they run on. Available in dual or single fuel configurations (gasoline, propane and natural gas), the WG Series maintains a common footprint with Kubota’s Super Mini, 05, 03 and V3 engine families. This gives you more horsepower options and greater machine design flexibility. Also, we have to mention there’s a deep catalog of optional accessories from oil pans to alternators offered by Kubota to meet your specific needs and ease your installations.
