Again go back to the fat kid on a teter toter. The more weight on one end, the less weight on the other. In this case the rear axle is the pivot.
If you lift a heavy load & the rears come off the ground 100% of the weight of the tractor & whatever load is sitting on that front axle. And that pivot on the front axle is almost assuredly starting to tip setting you up to roll over in microseconds.
If you have a load on the 3pt (even better, way behind for more leverage) weight is transfered from the front to the rears, regardless of anything on the loader. That leaves 3pt weight + transfered weight on the rear axle.
Proper ballast on the 3pt isn't high. It's usually as high as the axle or lower. Box blade, tiller, even a rotary cutter are all lower profile than most CUT axles. In that case it's actually got a lower center of gravity than wheel weights or any liquid ballast over the axle centerline.
Somebody on TBN actually weighed axles attempting to disprove this (I think, maybe he was trying to prove it). He found the numbers showed a very noticable unloading of the front axle in all situations.
So is the answer #1 or #2??
This gets very complicated and difficult to understand.
Your teter totter example isn't applicable. If the tractor was weighted in such a scenario the front tires would lift off the ground when the FEL bucket was dumped. Doesn't apply in this situation.
Sorry for the thread drift.
