I disagree. The floating top link arm (if I understand what you are talking about) is a free-jointed top link shown below that allows a few inches of flex in the angle the deck makes with the ground and with the tractor. One example is shown here and each mfr seems to have variations on the same idea. These folding top link attach points are better than nothing but still often lead to bent straps just like the OP showed. For my money I'll put on chains to replace the straps.
