This is actually because old tractors had a single
PTO: when you pressed the clutch pedal, it would only disconnect the engine from the rest of the transmission, but leave the
PTO and wheel drive locked together. With a dual stage clutch, the
PTO and gearbox are not locked together anymore when you press the
PTO clutch.
I have never worked with tractors without dual stage clutches... talking 1965 and newer.
