While the Kubota diesels do run at the same RPM's as the gas engines in the same applications, they have a unique sound to them that makes them sound like they are not working hard at all. And as their blocks and heads are thick and water cooled, the RPM's which are high for a diesel don't bother the Kubota's a bit. For their design, they never break into a sweat. Most of the Kubota triples put in the CC782D's still purr like new today. It became a popular little diesel for use on truck trailer refrigeration units. It's a typical overbuilt thing of days past that we will never see again.
