The Super 03 vertical, water-cooled, 4-cycle diesel engines ensure greater power, more efficient combustion, and cleaner emissions.

Super glow system comes as standard equipment to shorten preheating time and quicken engine start ups in cold temperature.

Kubota's inherent low noise design, a sound attenuated enclosure which effectively reduced all sound including that of the muffler, and the original TVCS combustion system substantially reduced the sound levels. Integral vibrations were also reduced by inserting rubber pads and additional supporters in critical areas. As an option, Kubota offers an easy to attach noise reduction kit, the Soft Noise Kit, for people who need additional noise reduction.

All switches and lamps are conveniently located in the center of the front panel for maximum accessibility. Transportability is also an important factor. Twin point lifting eye made it easy to transport all KJ Series generators.

All KJ Series generators are equipped with a transistor AVR (Automatic Voltage Regulator) to regulate a stable flow of current. Its convertible (50/60Hz) electronic regulator is powered independently from the voltage detection circuit, therefore regulation is not affected by distortions generated by the load.

The automatic shutdown mechanism automatically stops the engine should a problem arise with the engine's oil pressure or water temperature. Automatic air bleeding automatically removes power robbing air-bubbles from the fuel line. Emergency relay, timer relay, and safety relay are gathered into one unit to save space, simplify the wiring scheme, and to improve protection against water, dust, and vibration. This unit also includes key stop and mechanical manual emergency stop mechanisms. All rotating generator parts have been enclosed in a metal enclosure for maximum operator safety. In addition, all output terminals have been gathered on the side to reduce cable entanglements.

Oil, fuel, water, and filters are all located on one side for easy maintenance. The battery pack, which is located in the rear of the generator, can be easily removed through the back panel.
