Sandwich a piece of rubber between the plow and scrapper/wear bar. 1/2" thick is plenty and let it extend and inch or so and you'll save on tearing up dirt and grass as well as let the rubber ride on the new driveway. I've used horse stall mat, conveyor belting and even old snowmobile track belting with great results.Does anyone know of or where to find a wear bar for the Polaris Glacier 84” plow other than the steel bar it comes with? I have a new driveway this summer and don’t want to damage it come winter time. Thanks!!
