Curious if all mower blades are created equal?  What makes a zero turn cut pretty lines but yet my riding mower doesn't?  I bought our lawn tractor over 20 years ago and bought one extra set of blades for the 60 inch mower deck.  I've sharpened and re-sharpened them so much to the point where I need to just get a new set.  I am not easy on them though, if it's a stick that I can drive over that f'er will become mulch.  Someone please educate me if I should be going original replacement or some other fancy kind of blades that are out there?
