I took the picture, it is outside a little cafe in Benson. Looked at several times.
Its some wagon wheel tires, a cook pot & some kind of flat belt pulley.
As near as I can tell - it has no use.
Even harder to figure out is this thing. I think it was home made out of bunch of odd ball parts. Not all gears do anything, they are just there. Flat belt pulley does turn and may have been used?? On the back is a guide pulley. It does not drive its self. Has a short tongue, that looks like it should go on a 3 point or tractor draw bar.
