05 Series

The Kubota 05 Series is an established leader in its horsepower range and has been the preferred power source of various industrial equipment manufacturers.

  • Cleaner Emissions – Compared to conventional Indirect Injection and Direct Injection engines in the same class, Kubota’s 05 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 – Low noise levels during load and no-load operations were further reduced by 1 – 1.5dBA with the help of the E-TVCS, standard built-in steel strut Offset Piston, and the increased rigidity of the crank and gear cases.
  • 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.
  • Increased PTO Capacity for Beltdrive – The crankshaft has sufficient diameter, strength and main bearing area to meet various applications and to handle heavy loads.
  • Accessories / Options – A full range of accessories / options are available to meet customer’s requirements.
