Imagine a tractor with a very heavy implement on the 3PT. The balance/pivot point would be the rear axle. Imagine that 3pt weight was so heavy the front wheels were actually off the ground. Now, add some weight to the FEL and the front wheels will again touch the ground but they will not exert the same pressure on the front wheels/axle as they would if there was no massive weight on the back of the tractor. Weight on the 3PT or at least behind the rear axle will take pressure off the front axle when lifting the FEL. I agree loaded rear tires would not take weight off the front axle even though they would stabilize the tractor but weight behind the rear axle would remove weight from the front axle by pivoting over the rear axle.
Until you lifted enough weight to lift the rear tires and your ballast off the ground then all the pressure is again on the front axle. all your ballast does is keep the rear on the ground. I do agree if you were to hang 3000lbs off the rear THEN it would be unloading the front but heck you could be riding wheelies around with that much weight!! Anyway I have 1100lbs on my three point and loaded tires, I can still lift the rear off the ground with the rollback but it seems to be just about right. 1500 would be better but I still need to haul this thing and my 1/2 ton fusses already!!

I do have the rears loaded which must help a bit. I also unloaded my 1000-1200lb box blade with no ballast off my trailer on level ground. I could back up in 2wd but I wouldn't lift anything with my bucket that high on uneven ground, without the box blade on the back. Half of max lift does sound about right for level ground.
If 3,000lbs would take weight off the front axle, 1,000lbs would as well, just to a lesser extent. When we put weight on the 3pt, it turns the machine into a teter-toter, with the rear axle as the hinge point. Any weight on one end removes weight from the other end....it has to.
If you can unload [lift] the rear tires off the ground your teter toter point IS the FRONT axle right? So ALL the weight is on the FRONT axle including the weight you added. Now the only time you can remove weight off the fron axle IS when the rear stays on the ground. Like the post obove says that IS alot of weight. CJ
