Never said the mower couldn't last longer than that, just said there was a rating on them. Companies produce thousands of those engines a year and some will go much longer some won't last as long. I just pointed out that there were ratings. I understand that commercial lawn care companies put several thousand hours on their machines, but I'm sure there are several that may not reach 1000 hours even properly maintained. Some commercial companies may be able to put that many hours on their mowers in half the time it takes others, meaning the mower is not parked and sitting as long. Sitting for long periods of time can be almost as hard on engines as constant use. I change the oil in my fx series engine every 50 hours, and keep the air filter clean and I'm guessing my engine will not see 1760 hours before it gives out, because it only gets used a couple of hours a week for five or six months a year.
