How do I choose the right PTO?

How do I choose the right PTO? The formula to use is: Equipment speed ÷ engine speed = PTO speed. By way of example, if the required speed for a pump is 1,000 rpm and the engine operating speed is 1,500 rpm, the percentage of PTO speed to engine speed is approximately two-thirds, or about 67 percent.
