At least I am not the only one. As for reinforcing it too much, I don't think anything I did to the blade would have damaged the tractor if the blade was "Indestructible". The worst was first damage which pulled a scarifer through the mount. It hung on a tree root and pulled the tractor to a stop. I was in 4th gear mid range at about 1500 rpm, and about went over the front of the loader. I didn't even realize the scarifers were in contact with the ground, and I was dragging the entrance road to the property so i was obviously not planning to find any tree roots.
I think there is some definite room for improvement in the design, and I seriously doubt I could hurt the 3pt with any of the stuff I could do.
