I didn't want to put this in the welding forum because it's more related to getting more use out of blades. I was talking recently with a friend of mine tha told me when he wasn in Louisiana that he would take and weld hardsurfacing along the bottom (flat part) of his mower blades and that would do two things: 1) Make them last longer. 2) Keep a razor edge on them. He told me that the trick is to do it along the bottom, right along the cutting edge, then grind it down so it's very thin, and go with it. Said that the hardsurfacing is the same thing they use on dozer blades. Eric, Bill, all, what do you guys think?
