Well looks like that is settled by Ric. Non-greasable bearings should hold up fine. He also made me feel better about my Kawasaki FS...upon further inspection that 500 hour thing is basically saying it will comply with EPA standards for at least 500 hours nothing more. Not an engine lifetime expectancy whatsoever or anything. Unless it's a Vanguard made in partnership with Daihatsu. Stay away from the B&S Commercial Turf which is a beefed up Intek engine. Just look at Intek reviews on the official B&S website...nuff said. The commercial turf cyclonic is so new it only has 3 reviews.
Well the question then becomes what if the Snapper Pro is optioned with the FS Kawasaki motor........ The snapper definitely would seem to have a productivity advantage but I don't want to give away 1000-500 hours of life expectancy in the process. I guess my exhaustive research will now move on to the FX vs FS motors from Kawasaki..........
