I've been pondering this one for a few days.
I kinda fall into the 'better not say anything and let people think you are a fool, rather than opening my mouth and confirming it" category.
First things first, it is not a plow. If it is, it will be the first plow of this type that I've ever seen.
I think the wheel with curved spokes in the last picture is not a regular ground wheel, but a flywheel from the side of this equipment. Take a look at the width of the wheel. This could have been a free motion flywheel to keep the machine going, or a drive belt wheel so that the equipment could be powered by belt from a tractor or other type of engine.
My gut instinct is that this is a type of harvesting equipment.
Could it be a husker-shredder?
A husker shredder would have had planetary gears as shown in pic #2.
A husker shredder would have had an adjustable depth mechanism as shown in picture #3.
A husker shredder would have had rotating cutting blades shown in picture #7, that is, if those belong to the equipment you are asking about.
What I can't figure, though, is the set of gears pictured in #4. Are those gears made to trip another mechanism, as in timing gears?
At any rate, lots of parts have been salvaged off of this equipment. As a side note, you could be looking at the last example of this brand and type of farm equipment anywhere in the world! (That doesn't mean that it is valuable.)
