I picked my 9" plow extensions made by Superior Tech. This is the plow Deere should have made. I also got the 6' heavy duty cutting edge from Heavy Hitch which replaced the two 9" cutting edges on the extensions and creates one continuous cutting edge. I should add that the customer service from Heavy Hitch is second to none. With the blade fully angled to either side it can cause a little "scalping" but can be controlled. It works so much better than the 54" blade for getting the snow off to the side so you don't have to drive on it.
So John Deere, give us a blade for these compact tractors that harnesses their power and traction.
