That doesn't work all that well with the blades the OP and I have, at least not when the snow is wet.
Then it often gets stuck on all the stuff on the back of the blade, clumps up, and can even make ruts into the gravel. For me that means lifting the blade to get past the pile, then back up and push that snow off to the side.
Not a big deal with a fully hydraulic 3-way blade with offset, but it still gets old if it happens every 50 feet or so. Not that I think a pipe on the cutting edge is the ideal solution, or I would've tried it.
There are often times when I need the blade to cut into hardpacked snow and ice, and wish it weighed more than 1,600 lbs. That could lead to a lot of unbolting and then reinstalling a pipe.
But I might still try it on a smaller blade, used on a smaller tractor, for times when there's not much snow to speak of.
