I went to Tractor Supply and bought their 4ft. x 6ft x 1in Rubber Horse Stall Mat P/N 2219003 for $39.99. Cut a 4" x 54" piece, used the wear edge as a template to drill the holes, bought 10-5/16" 1-3/4" bolts, and bolted between the mold board and cutting edge. Been 3 winters of plowing 4500 sqft of blacktop. No wear yet. If it does get worn down, all I have to do is flip it over since I drilled the holes in the centerline of the strip. The hardest part was cutting the mat but a sharp utility knife and a straight edge gets it done in about 15 minutes. No marks on the blacktop. No more worn JD skid shoes at $47 a pair. Minimal gravel to rake in the spring. No torn up lawn. And the rest of the mat I used in front of my workbench. The only drawback is it won't completely clean the driveway when the snow is packed by being driven over. I'll live with that.. :thumbsup:
