Our local Deere dealer has an '07 model Z757 with a 60" deck and 153 hours on it. When I saw the price tag of $7900, I asked him "Are you serious or did someone put this tag on the wrong mower" ? He didn't have an answer and that's the only Z they had there, so I left. He called an hour later to offer me a new model Z720A with a 25 hp Kohler and 60" deck for $7100 otd.
