Super Mini Series

The Kubota Super Mini Series has been chosen as a power source for a variety of applications since it was first launched 25 years ago. It has become the benchmark in the compact diesel engine market.

  • Cleaner Emissions – Compared to conventional Indirect Injection and Direct Injection engines in the same class, Kubota’s Super Mini 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.
  • Large Capacity, High Speed Flyweight Governor – Instead of the conventional ball type governor, a large capacity, high speed flyweight governor is used. This ensures stable operation at a low revolution speed, and assures a high torque rise, and Steady State Governor Regulation.
  • 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.
  • Accessories / Options -A full range of accessories / options are available to meet customer’s requirements.
