I bought a blank of uhmw poly and drilled the holes myself for my 6 foot JD blade. Have it mounted but not much snow yet. Your in se Indiana so you can get it at Piedmont Plastics in Cincinnati. I called and ordered it over the phone. It was ready in three days and I drove down and picked it up.
/ Hard Rubber or Poly Edge for Kubota V5060 Snow Plow
Toro Wheel Horse, Gravely, Simplicity, UFT, David Bradley
I have tried both a hard rubber edge cut from a horse stall mat and a UHMW plastic edge on a 48" wide dozer blade. Personally I found the rubber edge cleared the snow better on asphalt. It acted like a squeegee. But neither cut through ice like a steel edge.
