Yep, I'm sure that is the same front QH that I have and that you are looking to buy. Looks like he's using one of the hydraulic systems to turn the chute?? That would be wayyyyy better than manual adjust.
Dang it.
The implement drive upstop is bolted to the top snow blower assembly above the chain drive and was present on the blower that was in the ebay auction. Everything needed was in those 2 auctions. The 2 bolt on brackets are not part of what I have on my tractor and may be used for the blade which I don't have?
I will snap a couple of pics tonight when I get home.
