Since we're waaaaay off topic here anyway, I'm gonna ask (probably knowing the answer) what is it about old machines like these that attracts us so much? They're noisy and inefficient and yet we love 'em, probably for some of the same reasons we love our plastic clown cars - an intimacy with the processes that actually make it go that you just can't find in modern cars. There's a certain childlike amazement that comes from knowing that your forward progress is due to mixing gas and air and throwing a match in it, causing a continuous sequence of explosions that a bunch of gears, rods, levers, and whatnot convert into motion. Those tractors are some of the most basic examples of this. I love it when the local Model-T group shows up at Cars and Coffee, as they're basically tractors with more seats and working suspensions.
