The Cockshutt Continental 1850 was a swanky tractor back in its day. It even had air conditioning, which was a must given it's a rolling greenhouse that can pull a haybine. While the concept of growing tomatoes while you seed a crop is great in principle, in reality you just wind up roasting a farmer alive.
I don't think the aircon works these days - a pigeon's head keeps poking out of the innards.
