So you haven't used a new chopper ? And how many dents have you had to bang out ?
Or did ya "look and "see" someone banging them out. You can come "look" at my mowers and "see" that I haven't had to bang on the decks and they have held up just fine.
Run a few for the next 3 or 4 years and "see" how they "look". Cause it sounds like to me you don't know crap about the modern Dixie's. Or maybe you have that super power where you can "look" at something and magically "see" how well it works.
