One issue I see with this is the when the pipe is on the front of the cutting edge, it would have a tendency of holding snow on the blade, perhaps if it was bolted behind the cutting edge would be better.
You could certainly do that. Or, mount it in the center below the blade, like s219 did.
My thought was, any ice and any obstructions would not be able to bend it away, with it in the front.
It's been the way it is in picture, for 5 years. And, it works great. Including when I back drag the plow.
It really doesn't hold any consequential amount of snow.
