How do you get variable land speed and constant PTO RPM?

PTO RPM has nothing to do w/ ground speed--independent drive train
gearing from that to axle drive shaft.

Well, nothing related outside the obvious that both are (for a given
gear) directly proportional to engine RPM...for the pedants

If I am reading that right, the axle has a direct gear ratio to the
engine (which is changed by the gear shift) and the PTO has a direct
gear ratio to the engine (which may be affected by shifting, doesn't
matter). If that is right the PTO RPM depends on the engine RPM. If the
ground speed is faster the PTO RPM is faster?

Are 540/1100 RPM fixed? The way to get a fixed RPM would be a hydraulic
drive or variable ratio transmission (as many cars have)?

If 540 RPM is not fixed how do you run a genset? You don't have to run
the genset while moving, but it would be real nice if there was speed
regulation to control the frequency.
