You definitely want it to float -- suspended on a chain. You wouldn't mount a solid fixed blade to the front of your truck. By hanging it on a chain, only the weight of the blade is riding across the snow. If solid / fixed mounted -- you have to float your loader so you add the extra 1000 pounds or so of the loader to the weight of the blade.
Just bolt or weld an arm with a hook on the end extending out from the SSQA plate -- just like you'd see on a truck mount. The geometry is best if your chain hangs pretty much vertical when in use.
As others have mentioned, a fixed setup is a recipe to tear up your blade or loader or whatever you hit that breaks first.
I know that there are a lot of comments about the blade being too far out front. I get it, but if it's pushing you sideways you need more weight / traction or you're going too fast or you simply have too much blade for your tractor. I think the plow up front and snowblower on the back is the best combination for the relatively few hours needed each year.
