Yes. The 3ph is essentially an imperfect [parallelogram] four bar linkage. When perfect this lifts a weight without pivoting it. Distance of the weight outward from the lifting force is immaterial except its effect on backtip.
Yes. That backtip resultant (a torque) is transmitted by Tension and Compression in the 3ph links acting on the tractor body at their forward ball positions. The supported cantilevered load (implement) only pushes downward on the hydraulics with its weight, but if that weight is centered far back those T&C numbers are huge.Does what you said, make sense to you if you think about it? The load set far back can “effect backtip”, but has no effect on the force to lift it up?
You have to practically scramble and reorganize your brain to make sense of it. Heres a thread from way back that made some temporary progress:
Conversion Factor for 3PH load capacity
