Message: <blockquote data-quote="RodNH" data-source="post: 50860" data-attributes="member: 4512">@OldMachinistMy S650 operator's manual has the same wording as the page you posted..."operate with engine at full speed for maximum horsepower". Seems like common sense - if you want maximum horsepower. However, what if you don't want or need that much power? For example, when I use my snowblower, that's when I want maximum HP and that's when I run at full throttle and hi-flow. However, when I use my backhoe, I see no need to run at full throttle. The backhoe works just fine at idle speed and standard flow, which, by the way, happens to be 1/2 full throttle engine rpm. The exact same situation exists with my logsplitter, my snowplow and my York rake. It just seems to be wasteful of fuel to run the engine at any throttle greater than idle when using these attachments. What, if any advantage is there in burning more fuel than one needs to in order to accomplish the particular job at hand? Is there any positive cost benefit for engine longevity/maintenance in burning more fuel than needed?I've read that diesel engines do best and last longer when run at full throttle under full load. I have no doubt that's true, but my normal use doesn't get to anywhere near full load for the majority of operating hours. I'm not in construction and heavy use as a loader is not the prime function. My skid is used only around my own acreage for miscellaneous purposes that are relatively short in duration (usually no more than an hour or two at a time) and intermittent in nature. What do you think I'm missing by running at idle the majority of time and not at full or even part throttle?</blockquote>
