DDT: The paint is wearing great. The scraper only has the usual wear of paint around the cutting edge. I sprayed the inside of the scraper with diesel fuel before using because the clay had a high moisture content and I did not want any to stick to it. It had no dirt/mud stick to it the whole day. I did the same every morning that week and at the end of the week the scraper still looked new even though it had moved in excess of 1,000 cubic yards of dirt.
I plan on getting it back out of the barn this spring for another >1,000 cy project. Hopefully I will have the same success as I did this fall. One last thing, from our calculations, we moved the dirt faster with the scraper than we could have with a John Deere 450 Bulldozer, about 41% faster.
