My 2005 757 z has just about 2800 hours. My buddy uses it everyday and its running great! I'm very particular with the maintenance on it.

The most mileage my family and me have ever put on a car was 405,000 miles. This would equate to 4,050 hours on a twin cylinder small engine. I have personally seen many mowers with more hours than that on them. A little trick to being able to quickly use this formula (when looking at a mower) is to simply add 2 zero's to the hours, and you've got what would be the corresponding mileage of a vehicle. (No pen, paper, or calculator needed)! For instance, if you see a mower with 1800 hrs on it, simply add 2 zero's (to the 1800) and you've got 180,000 (miles). Hope this helped, Stan
Stan where did you get this info from
I did a test 2 yrs ago with a GPS
I wanted see how many miles I could do in 1 hour. The lawn was 7 hrs long and I traveled 9 miles per hour

For sure Diamond. Like has been mentioned its all in how they've been taken care of.

My uncle has a small independent repair shop. Hes seen mowers come in with 5000 hrs on the OEM engine, hes had other come in with thousands of hours less...... blown sky high.

Fail to put oil in one and it'll let you down before 10 hours.

Its all in how they are maintained.

I've got an 02 Walker with over 3200 hours....... runs like a top.

My dealer told me that MOST, but certainly not all, air-cooled engines need some attention by the 2,000 mark with many needing replacement.

I agree that as with anything, how they are taken care of is a huge factor. For example, I blow the engine off as best as I can several times a day with my BP blower. Some guys probably do that once a year whether it needs it or not. I change oil and filter as close to every 100 hours as possible. Some guys probably do it when they get around to it, or not at all.

It is kind of like buying a used car, you probably would rather purchase one from a middle-aged guy with a nice looking house and yard than from a teenager or some guy down at the local low-rent mobile home park, because it has probably been taken better care of and abused less.

I know that kohler says you're good to change at 100 hours.

To me that is way too many hours and just really grates on me.

What the heck, oil/filters don't cost THAT much.
I change at 50ish. Some times its 49, some times its 52.
Change at the 50s on the hour meter, makes it easier to remember.
3000, 3050, 3100, 3150 etc

This should give you some peace of mind: I have an Exmark Viking with a 15 hp Kawasaki FH451V engine. This October, it will be 10 years old and have around 9000 hours on it. The only major repair was a left valve replacement at 3500 hours (cost about \$450.00). Since then, I have only had to replace an ignition coil (\$40.00). If you change the oil, spark plugs, and filters at their proper intervals, your engine will last a long time.

My Kawasaki manual says every 100 hours on the oil, 200 on filter. I change both around a hundred. I don't have the time or feel the need to do it every 50 hours. Id be changing oil every 3 weeks.
