No, that's what I meant to say, but maybe I am wrong.Henro said:Did you mean to say that extra weight on the back adds stress to the REAR axle? I suspect so...
If there isn't enough rear weight, the back end rises up and the pivot point is the front axle. In a perfectly balanced tractor (tractor ballet? ), as you raised a filled FEL, there'd be a corresponding and equal rise at the backend. With both the FEL and the rear end off the ground, the front axle is supporting the entire tractor plus the contents of the FEL. This weight transfer to the front axle still happens as you add rear weight to keep it on the ground, the tractor attempts to pivot around the front axle.
To use a playground example...What would happen if you kept adding equal weight to both ends of a see-saw. Eventually, if the board were strong enough, the support in the middle would break.
