I don"t think you understand how the dual clutch transmission works that I linked. It is for all practical purposes a powershift transmission, not a different way of shifting gears as you"re describing. It is a shift under power up or shift under power down type of set up. You can powershift between all 6 gears. Imagine the old Allis Chalmers Hi-Lo setup on the "D" series (I have a D-15, that"s why I use that as an example) and then imagine this, you"d push the lever forward to engage the clutch for the 2-4-6 gears and shifted the 1-3-5 gears to whatever gear you wanted to select next while the other clutch was disengaged. You"d then pull the lever back to engage the clutch for the 1-3-5 gears. That"s why the transmission in the article has three shafts and a shaft within a shaft. You would have two sticks on the tractor, one for the 1-3-5 gears and one for the 2-4-6 gears, each shifted independently.

After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
