Tiller mule drive? Or what?

I bought this for the snow plow welded to it. PO said the snow blade was attached and used as is but it's still a mystery to me...

Hoping someone could explain it to me!

Thanks

Didn't understand it when I saw it on Craig's List but felt sure I would when I saw it. Now I own it and still don't know what it is!

Do note the A frame for the blade sitting on the ground and of course the blade is off camera to the right. You can just catch the left spring in the upper right corner. A short angle iron was welded across the plow frame hence the dark weld areas. But the angled idler? The pivoting brackets with short pipes towards the front? With the blade where it would be used, what would the short pipes hook to? And what would the hangers on the rear of those brackets fit? The flat and v pulleys towards the rear? There are so many mysteries that I'm completely baffled...

The PO said it came off a Wheel Horse and the dozer blade is certainly a WH but I suppose the assembly on the back could be off something else? And maybe it did NOT come off a WH? Maybe someone added a WH dozer frame to whatever tractor they had? Several red tractors out there!

Still very confused...

? Never seen anything like that Dennis. Gotta love these previous owners

You know, the assembly may not have come off a WH... Pretty sure the fellow said he saw it work, but whether he could tell a Wheel Horse from anything else I don't know.

Dennis after careful study, that looks like a short frame Wheel Horse blade that has been grafted to whatever the rest of that is. Guessing it's some sort of accessory drive.

I think you are right on both counts, but the problem of "whatever the rest of that is" persists.
