John,
I like the idea of the "rubber" scraper attached to the blade. I have been thinking about doing the same with my 54" blade for my 1512. How thick is that rubber? I have found a place online and actually only about 90 miles from where I live that sells various lengths and thicknesses of rubber designed for plows. I didn't have a chance to buy a piece for this year, but was considering doing it for future seasons. Also, what is the verticle size of it? I estimated that if I buy rubber that is 4" wide, I can drill the mounting holes in the center and have it be reversible for when one edge wears out.
