    I just had a hinged back drag blade fabricated. Made it out of 1/2 x 6 cutting edge. Welded 3 ft of 3/8 x 3 in angle iron in the middle to reinforce it. It snapped right after the angle iron. Anyone have this problem?

    Been using mine for over 2 seasons now. Never any issues (knock on wood). Maybe the welds weakened it.

    Pictures?

    Cutting edges are hardened steel, you will create a point of brittle material right next to the weld. You'd be better off just using cold rolled steel, you won't wear it out quickly either way, not like you are doing miles and miles in reverse.

    That's what I'm hearing. I guess when u heat up the cutting edge it weakens it. I'm going to have it welded back together and put 3/8 angle iron the whole way. If that doesn't work I will use rolled steel.

    Is there any supports on the back of yours?

    Is it a cutting edge or roll steel?

    No supports just the 1020 carbon steel, and 4 brackets that are welded on the blade for mounting. I'll try and get a pic for you tomorrow.

    I've had it happen once or twice with our blizzard plows. Just weld it back together, it will hold.

    Make sure you, or whoever does it stick welds it though, not just wire feed!

    Why not wire feed?

    I tried wire feed on mine the first time it only held for a couple of hours and re broke. Then I stick welded it and its still holding, that was about a year ago.
