For the past few years I have been plowing my concrete driveway with a 54" blade on the X485. The cutting edge is urethane and the driveway is concrete. During this time I have used the factory skid shoes with no problems. Since the skid shoes were wearing out I replaced both the cutting edge and added the Heavy Hitch skid shoes that they make for the 54" blade. These are much more heavy duty and should last longer.
The problem is I'm not happy with the Heavy Hitch skid shoes. They are louder then all heck to the point my wife can hear the banging and rattling from inside the house even if I'm at the road. The skid shoes are about a 1/4 above the cutting edge but anytime you hit a bump in the driveway, road, grass etc they vibrate and rattle like there is no tomorrow. I often plow snow at 4 am and I guess if my wife can hear the noise the neighbors may as well.
Today I had enough and removed the skid shoes. I'm back to nice and quiet. That leads to the question. Are the skid shoes necessary? I know if the cutting edge gets too low I will wear out the blade itself but I monitor that each year as I am putting it away.
The downside is Heavy Hitch charges an arm and leg for these skid shoes that are now junk to me. If anything I will go back to the factory skid shoes which still means the heavy hitch is heading to the garbage. .
