Kubota 03 Series (SI)

The essential appeal of Kubota engines lies in their ability to address a wide scope of uses, while rising to the stiffest of challenges. Simply stated, the true charisma of Kubota engines, which are at the global cutting edge for small-size industrial diesel engines, comes from the sophisticated combination of high power density, onboard interchangeability, and multi-fuel drive. Adding to this their ability to satisfy multiple emissions standards in both developing and industrialized nations, Kubota engines offer solutions to the difficult issues faced by customers representing diversified uses and regions. With various specs positioned for both in-house mounting and external sales on the strength of models responding to the inevitably wide variety of market needs, Kubota fields a lineup that dramatically expands customer options. Series are supplied across six different models, ranging in displacement from a minimum of 479 cc to a maximum of 6,100 cc (in-house mounting only), and in output from 4.1 to 157.3 kilowatts. Besides examples of in-house mounting on tractors, combines, generators and other products, there are also extensive examples of mounting when it comes to other brands as well. That long list begins with their mainstay agricultural machinery, while going on to include backhoes, aerial work platforms, skid-steer loaders, dampers, utility vehicles, riding lawn mowers, sweepers, wood chippers, power generators, refrigeration equipment, forklifts, telehandlers, power generators for motor homes, mobile floodlights, scissor lifts and numerous other uses.
