So I am using an 8' backblade to push snow this year instead of the lighter duty 6' I have used in the past. I had a piece of 2" schedule 40 laying around so I slit it with the circular saw and beat it on the bottom of the blade from one end. Was a really tight fit. Lasted a couple plowings and was a noticeable improvement in the fact that it did not catch near the gravel and did not scalp the yard. The problem was it only lasted a couple uses till it broke all jagged one day while I was plowing when it was only about 10 deg F. My dad put a piece of 1.5" on his and it also broke, however it was about 32 deg F when his broke. Does anybody have any experience with these, and if so did you have the same problem? Any recomendations?
