Advanced Technology

 

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

The "Quick Glow" system comes as standard equipment to shorten preheating time and quicken engine start up in cold temperature.

 

Highly Reliable

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.

 

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 and options are available to meet customer's requirements.
