Saw, it seems to me that the other forum members are generally right on target here and you're being a little unreasonable. I'm sure smart engineers could design a system that would prevent the radiator from getting clogged, but then your tractor would have some elaborate contraption attached that would raise the cost of the tractor by thousands, and cost just as much to maintain anyway. Bottom line, if you are going to mow, take a bit of time occassionally to clean the radiator...it's not that big of a deal. I don't mean to be testy here, it's just a common sense thing.
