I built a small blade several years ago for a snapper rer out of a piece of schedule 80 6" pvc and was really surprised as to how well it worked.I did not use at ramming speed but really bent the 1/4 bolt I used to hold the angle.I then made one for a lt out of the green pvc sewer pipe but never used it.I do have it where I can mount on my cc as I made a custom mount for the cc and have a 48" husquavarna blade on it.

Why not add a piece of steel that is the same gauge or close to that goes 1-2 inches above the holes that hold the wear strip on. Them I would buy a replacement wear strip and new skid shoes for your blade.

The only down pressure I have is from the weight of the blade. You need to have some float in the lift system when pushing snow. If you don't pins in the lift system will break or lift arm will bend.

as far as putting plastic on the blade, just put it on over the steel face, use pop rivets to hold it in place. Dad and I used to do that with our truck plows, worked great, works just as good on garden tractors.

I built a blade, and it worked very well, the mounts, on the other hand, were a different story. I cut a 50 gallon drum in half, put the pieces together, drilled holes, and used machine bolts to hold it together. Wallah, snow blade. My original plan was to mount it on the back. My 100 pushed it fine, and it worked, but it looks like it was putting abnormal pressure on my sleeve hitch, and ruining that is not a risk I'm willing to take. If you're wondering, I cut up an old bed frame and used the angle to build the mounts. I keep meaning to weld them in a different way so I can use it on the front of the tractor, but I bought a blade for $65 off craigslist, and now have no motivation to reconstruct mine!
