Does the replacement cutting edge supposed to have a crown to it? Obviously the edge itself is a stamped “U” shape. I mean if you lay it flat on the ground the cutting edge will rock side to side lengthwise. Think of it as my cutting edge looking like a smile. When bolted to the blower the blower will now rock side to side. I had to use 3 washers to levell the cutting edge with equal gap on both sides about 3/8”. Then I adjusted the skidshoes 1 washer above the ground 1/8”. This way the edge will wear in flat before the skids start to contact the driveway.
I also built up my skids with weldding rod in the low spots and used some hard face rods. Will see if it makes any difference. $56 per shoe seems a bit outrageous.
