You buy diesel when you get fed up with gasoline engine problems. Really the only time a diesel is louder than gas is at idle. Seems to me once you start to work you have to run a gas engine harder so noise is about the same. And for sure you don't have to fuel up a diesel near as often which means less money and work for me and that makes that idle noise pretty insignificant.
Very true. I put over 3000 hours on my Kubota. I put a new fan belt and water pump and 3 sets of tires on it in 6 years. I got a new one last year and gave that one to my son who now uses it. And I took off the original muffler and welded on a car muffler. Helped the sound a lot. And I now have 1800 miles and over 250 hours on the new Kubota I bought in July of last year.
