25hp Kubota Diesel Engine

Scag Liberty Z

The 3-cylinder, liquid-cooled, 25hp Kubota diesel engine is a perfect compliment to the Turf Tiger. This reliable unit achieves high power density from its larger bore and stroke sizes, enabling it to deliver more power from a smaller crankcase. In addition to its power and performance, it also delivers maximum fuel efficiency and cleaner exhaust. Operators are also sure to appreciate the low noise levels.
