The 54" blade is one tough blade. It is a legitimate medium duty blade. It is plenty tough for a 4115. The mounting bracket is very solid and quite heavy. The reality here is that a 1750# machine can generate a lot of force. If one hits a stationary object, or a big frozen snow pile, kryptonite will not stay straight. This problem is compounded by the ability to angle these blades; the force from any impact is not distributed evenly across the surface. I would say any impact such as this would have bent or damaged any blade, except maybe the Frontier boom blade I had for my 4520. Of course, it weighed 500# and a 4115 would not be able move it well. I would say you had an unfortunate mishap that placed loads on the blade, bracket that it could not handle, resulting in the damage. I think the blades themselves are very strong and would likely handle almost every other instance.
