But the physics show, with a slow steady pull, that it cannot happen. When you throw clutchpopping, jerking, running starts, and hills into the mix, its a crap-shoot. Anything can happen. And wether the tractor can attain enough momentum to go over depends on how hard you jerk, how hard you pop the clutch, how fast the running start is, and how steep the hill is.

OK, physics says it can't happen. But it does happen on the flat and level without all the drastic actions mentioned above.:thumbsup:
Maybe the Physics needs a new model to work with or maybe a new approach or maybe just a new force diagram with the actual forces involved??
I think you are right here, and by the way your post #193 made sense to me.
Do any of the theoretical physics models include resonance conditions in the system?
Do any of the theoretical physics models include the dynamics of tire flex and other forms of stored energy in the system which may build up and be rapidly released?
Do any of the theoretical physics models include the effect of a tall 350 lb operator leaning backwards rapidly while sneezing and pulling back on the steering wheel while the front end is in the air?
Do any of the theoretical physics models consider the forces from a high speed headwind gust which catches the underside of the ROPS mounted canopy and tractor belly while the front end is off the ground?
Do any of the theoretical physics models include the effect that the ground is soft and the drawbar connection point pushes into the ground as the tractor flips over backwards?
Do any of the theoretical physics models include the effect that the turbocharged tractor engine exhaust pipe opening is elevated and facing forwards and therefore producing thrust which tends to cause the tractor to flip over backwards? (assume also that the engine air intake and radiator cooling airflow further enhance the effect).
Do any of the theoretical physics models include the situation where the rear tires dig holes as the spin which lowers the rear of the tractor and moves it backwards slightly and then traction increases instantly when a couple of thousand pounds of liquid ballast in the rear tires that had been sloshing around and became momentarily unweighted suddenly became fully weighted and the tires stopped spinning and the tractor rotated and did a back flip?
Do any of the theoretical physics models include the effects of radiation pressure from forward facing high powered lights with reflectors?
Do any of the theoretical physics models consider what happens when the front tires on a 4wd tractor get coated in 500 lbs of thick heavy mud and then the front end of the tractor lifts into the air and then as the front tires are spinning rapidly in the air all of the mud is released and thrown at high speed downwards and out in front of the tractor?
Do any of the theoretical physics models consider the effects of unequal and rapid variations in traction between the two rear tires when the rear tires/wheels are set for maximum tread width?
