Re: How are
GarageSmoker,
I put on 50,000 miles minimum a year driving (not the tractor, of course... my wife would disagree), and have broken in over 13 engines, including diesels. Most owner's manuals say not to exceed certain speeds, or run the engine for high RPM's for extended periods of time until broken in. I pull them off the lot and drive them at highway speeds for 5 hours non-stop to home (Northern Wisconsin to Northern Illinois). Can't say there has ever been a problem. I figure the same with my Kubota. It should be broken in like it's going to be used. My Kubota dealer contradicts the Kubota manual and says to tach it up right out of the box. He does, however, say that you should let the diesel warm up 15 minutes or wait until the temp gauge moves to avoid hot spots in the cylinder before you put it under load. I would have to agree with him based upon my experiences. I had a small engine business for 12 years, and I can't tell you the amount of people who would bring in a unit with unbelievable carbon build-up because they would only run their equipment at half throttle. I think this could be a serious problem with a diesel, when it generates less heat than gas engine. My opinion.
