I think I read some place that the U.S. is 540 but in other
countries they have the 1000 rpm equipment

Generally 540 only up to about 70 hp. 540/1000 on 70 to 150 hp. These will have 1 3/8" 1000 rpm 21 spline shafts.
Above about 125 hp, they will be 1000 rpm 20 spline 1 3/4" shafts in the USA
Mowers are ordered with 540 or 1000 rpm gearboxes from the manufacturer.
