Well, not quite the same! V8 pressure plates have the centrifugal weights on the fingers to add clamping force as the RPM's go up. You can notice this in a V8 car or pickup by revving the engine with the clutch pedal held down. As the RPM goes up you can feel the clutch pedal push back harder. Tractors had no need for these wieghts as they were half the power of a V8 and only ran at 1600-1800 or so RPM.
