Once you understand how the hydraulic ram pushes the long arm that goes to the rear of the tractor you will be able to understand how the extreme three point works. It is essentially the same as the regular lift but due to the mechanical advantage of the three point arms behind the rear plate, it gives more lift range and allows implements to be raised up but remain horizontal while doing so. I have a John Deere 332 diesel garden tractor and the three point hitch works in about the same way including the arm from the ram and the mower deck going up and down with the same ram.
