Well,, I just set up one of my plows with a urethane edge. In the process I had a couple pieces of urethane that I cut off the edge. I have the whole plow apart, sandblasted and painted it and ready to hook the moldboard to the A-frame again and I got this hot flash. Being a full trip blade it hammers something fierce when it returns to battery after tripping. So, I am trying a couple small block of urethane on some homegrown mounting pads to buffer the blade just before it hits the metal stops. Vince, I'll let you know how it works when I get to use it.
