Reliability has been built in every step along the way from design through manufacturing. For example, all main parts subject to stress and wear, such as the crankcase and the crankshaft, have been strengthened and made more rigid. Further, as the Kubota horizontal diesel engine is water-cooled, its superb cooling characteristics eliminate overheating even when surrounding temperatures are high or when the "Lowboy" is operating under a heavy load. Another feature is the long-life cog-belt by which the engine drives the generator. These are just a few of the factors that makes possible a longer, more reliable engine life with minimal maintenance costs and pocket-pleasing economical operation.

The Kubota horizontal water-cooled diesel engine is fitted with a high-performance governor that promptly responds to load fluctuations to bring about stable operation.

Coupled with the superb fuel efficiency of the Kubota horizontal water-cooled diesel engines that are known world wide for durability and reliability, the large-capacity fuel tank makes possible longer hours of continuous operation.

At Kubota, full attention is paid to achieve the highest levels of precision and balance to suppress vibration and to ensure that the engine operates smoothly. Noise in the "Lowboy Silent Series" has been reduced by the installation of a large-capacity muffler. In addition, steps have been taken to further bring both vibration and noise down to the absolute minimum by installing a specially developed insulating liner on the inside of the enclosure that is both vibration-damping and noise-absorbing.
