Wrestled around with my snow plow a bit. I managed to break the mount. The entire lower half of the C bracket that the blade hangs in, is gone. I kicked around the snow banks a bit but still haven't found it. Its probably lost until all the snow melts and it is time to either rake the yard. or mow it for the first time. aka..... I'm not finding it any time soon.
