The power shift is basicaly an automatic trans without a torque convertor. The clutch is actualy a dump valve. There is a torque damper on the flywheel though. It is like a clutch with no release forks although JD did have a release mechanism on some early model 3020's.The PTO is part of this package also and is engaged hydraulicly.
The early synchro range is a pure gear transmission with a dry type clutch. The PTO is incorporated into the main clutch setup but is controlled by a seperate lever and not by a two stage pedal. The slot machine shifter really controls a 4 speed main with a 2 speed. This gives you 8 forward and 2 reverse speeds.
