New Cutting Edge Prep

    I just replaced my worn out cutting edge with a new one. It's a Fisher MM1 HD 9'. Interesting that the old edge was 1/2" and the new one is 5/8". I'm plowing a long gravel driveway now, and after a thaw and re-freeze and new snow, the blade is rattling and banging like crazy, even after lowering the shoes to the maximum length.
    I wonder if I should prep the bottom of the new cutting edge with an angle grinder to round off the sharp square edge? Does that make any sense? The concussion that's being transmitted through the frame is pretty severe. I don't like to abuse my truck and plow any more than necessary!

    Roll....shake... rattle. I run it down dry smooth pavement without shoes a few times, but I have ski area access rd. to do this. Go Slow till the blade is worn a little.

    Mine does it as well. With and without a pipe on the bottom for gravel. I just live with it.

    Nothing better then a fresh cutting edge. If you want to break it in ,run it down the road ,that will take care of it.

    Keep it angled on the gravel, it should help some.

    I have found that if you have plowed with a cutting edge long enough to wear some off of the trip edge,the added height of the new edge has so much more leverage on the trip springs that it makes the plow dig in and trip the edge like crazy.
