Well, the problem with finding one used is, you and every other deere mower owner are looking for one. I have a LX172, and the first thing to fall slam off of it was the hood. It was patched, and patched until it finally was in too many pieces to worry with. During the same time, just about every other plastic part became brittle and broke. In my opinion, Deere should have stood behind this. That was B.S. You pay TOP DOLLAR for something that YOU THINK is quality, and it falls apart around you. THEN you think your just going to call the dealer, and order replacements for the all the plastic. JUST THE PLASTIC PARTS cost more than I could sell the whole unit for. But hey, "Nothin runs like a Deere!"
That is why I have a nice, shiney Orange machine now. You know why it's shiney? THERE'S NO PLASTIC!
Anybody interested in a used LX172? Runs great, but looks like heck because ALL THE PLASTIC HAS BROKEN OFF.
OK, I'm done venting, but I feel your pain.
