I'm not sure about the RPM but I know it's not full engine RPM because it runs off the main shaft in the trans and that turns at a reduced speed because it is driven by the reduction gear.
Edit: Did a little research, the input gear according to Mid West Super Cub has 12 teeth and the reduction gear according to Parts Tree has 84 teeth so 84 divided by 12 is 7. Engine RPM of 3600 divided by 7 would give you 514 RPM's at the rear PTO.
