Just thinking out loud after reading the back blade comment.
30 years ago, my Brother-In-Law broke his back from a tractor flip while dragging down a widow maker...old tricycle tractor and was not there, so not sure how he was actually doing it...
If the 3PT hitch is really just providing up lift, (no down pressure) - then can it really stop or prevent a back flip?
Understand the sound logic of always carrying a load low, near the ground...to drop the weight quickly...
But the 3PH does not really act like a wheelie bar on a dragster - there is no real mechanical block from the 3PH preventing a back flip? (That's a question, not a statement).
Not asking this to question the poster or cause conflict, but rather to accurately understand the dynamics on whether a blade on the 3PH will actually stop a back flip.
