This comment proves your lack of understanding. You could have 30 axles if they are all fixed the the frame (and for simplicity we will assume tires do not compress) and if I add weight to one end the fulcrum moves from the other end closer to the end I’m adding weight. Mathematically you could have 10,000 pounds in the FEL and add 1# behind the 30th axle and find out exactly where the fulcrum is.
Spoiler alert, on any tractor on the market the fulcrum is somewhere between the two axles and moves constantly depending on what you’re doing with each end of the tractor.
