That's what I thought about not seeing the trunk under the tractor until I went to full screen and better resolution. Then I could see the trunk. That beast has been parked for a lot of years it appears.
Rob, I see what you mean but I don't think its a photoshop. The tree is growing around the steering shaft.
But, if it is real I know exactly what I'd do if it were mine. I would restore that sucker to like new condition right there with the tree growing up through it! That would be so cool!
Edit: Look closer. The trunk is there. The front edge of the trunk is at the same angle as the tread of the rear tire.
