Dealer got a kick out of one of my Toro walk behinds we're still using as a semi-every day runner/back up. Dad bought it in '88, been through multiple, multiple hourmeters. It used to average 500-600 hours a year, now down to 200-300. Probably has 9-10,000 hours on a Kawasaki 12.5hp single that has NEVER been apart and i think has the original carb on it. Pretty funny. Can imagine how much fuel has been through that thing? There's a couple others around here that have 6,000-10,000 also. Not all good luck around here, couple Kohler twins have shucked engine parts around 800 hours, grrrrrr..... But couple other Kohler EFI twins have 3000-4000 though!!
