Hey Kevin, I tried the stall mat edge a few years ago. It works great ... Frank Look here: http://www.tractorbynet.com/forums/owning-operating/138608-rear-blade-rubber-edge.html
OP- I just wanted to let you know that a lot of the "riding up" on the snow by the blade can be eliminated by adjusting the top link longer to angle the cutting edge forward and down which makes it cut in a lot better.
I was wondering if adjusting the top link would help. I know right now it is as short as it will go. I shall move her out some
