Kubota Super Three Series

Making a more fuel efficient, cleaner exhaust engine has always been a top priority for Kubota. Our long technical experience, untiring research, and deep concern for the environment led to the development of the Super THREE Series. A family of 3 – 5 cylinder , Indirect Injection ( Indirect injection) liquid-cooled diesel engines with emission levels far below the set standard according to California Air Resource Board (CARB) Utility, Lawn and Garden Equipment (ULGE) regulations. Super THREE Series represent Kubota’s commitment of finding a more harmonious way to coexist with nature.

  • More Information

    • Cleaner Emission – Compared to conventional Indirect Injection and Direct Injection engines in the same class, Kubota’s Super THREE Series has attained cleaner exhaust thanks to E-TVCS (Three Vortex Combustion System–Kubota’s highly efficient combustion system produces an ideal air/fuel mixture by creating 3 vortexes in the combustion chamber. This results in better cross flow of air and exhaust gases, lower air intake temperature, and improved combustion efficiency.)
    • Low Noise – Noise levels during load and no-load operations are kept to a minimum with Kubota’s renowned low-noise diesel engine technology and E-TVCS.
    • Quick Start Ups – “Quick Glow” system comes as standard equipment to shorten preheating time and quicken engine start up in cold temperature.
    • Highly Reliable Engine – Based on Kubota’s original sturdy design, the engine promises great reliability and long service life with advantages to meet most any application.
    • Asbestos Free Design – In addition to the excellent features such as clean exhaust and low noise, we have also designed them against asbestos pollution.
    • Accessories / Options – A full range of accessories / options are available to meet customer’s requirements
