I have recently posted an explanation of engine power to the long drive pinion shaft here already, aka, H/L explanation.
In this post I will try to show how the F/R planetary of old Gravely two wheelers can change the direction of travel for the tractor.
This video tells my tales, but one thing to remember is, the long drive pinion shaft never reverses direction, and that is the same shaft driving the PTO.
