Tudor you need to show me where that is a written fact. Everything you read about a loader and counterbalance always refers to proper ballast behind the rear wheels.

Greg, the comment was written addressing the specific issue of stress on the front axle, not counterweight in general.
With no counterweight and a max capacity load in the bucket, traction will be at a premium. If the tractor can move, it won't be very fast with limited traction and a small obstacle will stop it. By adding a ballast box, the traction will be improved and the tractor will go over that same obstacle with ease and probably with some speed, thereby placing more stress on the axle just from impact with the obstacle alone.
Bottom line, improved ballast
increases stress on the front axle.
I tried to see where you were going with this, but its completely inaccurate....refer to the owners manual and how and why ballast is needed might help you...
I don't know what your owners manual tells you about this, but the lift capacity of my GT's FEL far exceeds the weight of the tractor. With no ballast at all, a max capacity lift for the loader will only succeed in lifting the rear wheels off the ground placing the entire weight of the tractor on the front axle along with the weight of the payload sufficient to balance it.
By adding ballast to the tires, 320 lb, chains, 30 lb, wheel weights, 80 lb and rear blade, 250 lb, for a total of 680 lb of counterweight, it will still lift the rear wheels off the ground. With only the front wheels making contact with the ground, guess where all that extra stress ends up.
This has nothing to do with the rules set out in the manual for the safe operation without damage to the tractor, and everything to do with the laws of physics for what will actually happen.
I've been playing at the top end of the lift capability spectrum with my GTs for over 3 decades and have broken the spindles right off the front axle in the process. The maximum scaled lift and transport for my GT was over 1400 lb plus the 210 lb bucket. I have no idea at what lift level the rear wheels will come off the ground, but they have, and with all of the above ballasting in place.
Counterweighting of a FEL equipped tractor is essential for safe operation and maximum capacity. My post was aimed only at the incorrect statement that improved ballasting
reduces stress on the front axle.
