Well Google is sure worthless these days. I did a search to see how the 255 is regarded and what problems they have, about 100 sites selling them, no real info. But the 255 looks to be the big box store machine and the actual Deere dealer probably wouldn't want to handle it used. I'd put it on Craig's list or FB Marketplace for $1000 or so. The 540 seems to be only available at the dealers? Price is not out of line compared to the 535s listed in all the other stores.
