You can purchase a spline adaptor to get from 1000 splines to 540 splines. You then run 1200 on the tach and your PTO will be running at 540. If you need a high horsepower 540, this will not work. The engine is gutless at this RPM as you are below peak torque.

It would be cheaper to trade the 540rpm pto equipment for 1000rpm. That is would be to have custom gears cut for the 4630. There is an external changer gearbox which also requires a longer drawbar.

Walked around my boss's 4520 that he bought at auction in the US. and found 1000 mid pto and 540 rear. I need to check into it further.
