New to me, Suburban

So I was able to pick up a Suburban with a deck, 3pt, and turning plow. Also had a leaf vac that hooks to the 3pt. Engine smokes and has a slight knock to it so if I keep it there may be a repower in the future. I don't recognize the deck though, looks to be made of plate instead of stamped. Anyone know if its supossed to be a floating deck, because the front axle appears to be vert worn from the weight of the deck. Here's a few pics, tell me what you think.
