Thanks for the link. I've been to that site. Unfortunately I have to be a member to get the doc. I agree with you that the pull alone will not flip the tractor with a properly attached load. However, when you state it can't happen, it's a bit misleading, because you are disregarding the additional flipping force due to power and traction. If you have the traction and the load is keeping the tractor from moving forward, then torque will do you in. Longitudinal stability is NOT just a function of drawbar geometry. It is also a function of tractive coefficient. See pages 140-145 of the reference book link. While these conditions might rarely exist in the real world. Telling people it CAN'T flip is dangerously misleading. Extreme traction conditions (we know they can flip if frozen down) and modifications to the weight - fluid in tires and wheel weights - can be just as deadly as hitch point modifications. CAUTION - The referenced link is to a VERY large pdf.
