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.
How do you calculate PTO gear ratio?
The proper P.T.O. model has the necessary torque capacity and operating speed that most clearly meets the needs of the application P.T.O. Operation Page 14 The gear ratio is determined by dividing the number of teeth in the driven gear by the number of teeth in the driving gear (24 ÷ 12 for a gear ratio of 2 to 1).
