Bruce I am doing some checking on this with a couple of WKC members and will hopefully let you know later today.
Here is what I know - the same kettle today is known as the Weber Original Kettle and sells everywhere for $109
without the logo. The John Deere model is just your ordinary black kettle with a logo on the lid. IF IT WERE
ACTUALLY JOHN DEERE GREEN, that would be a different story.
Google seach shows some WKC chatter about these grills from 2017 and no one was particularly
excited about them. New in the box helps a little, and the logo will help a little.
Purely guessing at this point I'd say $125, maybe $150 tops. You will likely want to buy in the $50 to $75
range to make it worth your while.
