I got a lowes special,yard pro or something like that,,its going on its 14th year too,,have changed the belts and a few small parts,,,but it still cuts!
Also got a sears mower,,going on about its 12th year,,,,had to have head gasket replaced when it had about 100 hours on it,,,and belts a couple times,,of course batteries for both at least once,,,both have kohler motors,,ones a hydro the other is manual,,one is 25 hp the other is 20,,,,have spent less than probably 500 dollars repair on both in the 14 years,,,so,,,,cut over an acre of yard,some rough,some hilly parts,,and generally don't cut grass but once every two weeks!
You can get about three of these types for what you'd pay for a new top of the line one,,,so if each one just lasted you 12 years,,,thats 36 years of mowing fun!!?? and you don't have to save for three years or make payments to get one,,well,,generally speaking of course....
1/2 acre or less grass to mow,,it just makes no sense to me spending over 5,000 on a lawn mower,,,now maybe if you had an acre or so like me,,yeah,,it might make sense,,if you could afford it that is,,,but the cheap ones cut the grass just fine. thingy
