Putting a 2.75" hardened steel pipe on rear blade for plowing in soft conditions?

Thanks for that. It looks like the back of your blade is pretty smooth vs my blade which has a bunch of perpendicular reinforcements all along the bottom of the blade where is meets the moldboard. That might account for the difference in the snow clearing capabilities of the two (back) blades.

No doubt that’s true.
