One way to check the H speed going by RPM is to figure the overall gear ratio in 5th. Its 16.83, multiply by 168, = 2827.44. Check the radius of tire used, I use the measurement from center of axle to ground with tractor weight on the tire. Multiply the RPM you are turning and the radius measurement. Say you turn 1600 RPM, multiplied by a loaded tire radius of 28.6, that = 45750. Divide the 45750 by whatever gear ratio you use X 168. In this case 2827.44 divided into 45750 = 16.18 MPH. Some use tire diameter, so 336 instead of 168 would be used. Hope I didn't mess up in explaining that.
