Nice to know the 790 rates well. I'm looking at a low hours used one today. I didn't start out looking for a JD, but 3 used ones with low hours reasonably priced turned up in the area, a 770 which sold before I could look at it, then an 855 which turned out to not be equipped quite like I wanted and now this 790 with 370 hours on it. I understand the Yanmar engines are very durable. The 855 is a hydro and the 7s are gear but I don't really have a preference and the 27 hp of the 790 in a manageable sized package is vey attractive.
Harley, enjoy your new tool/toy.
