I went through my teenager years driving one of those MF 135 machines. A very versatile tractor. I enjoyed driving tractors (including a much older MF), when I eventually got my car's driver license some years later I found that driving cars weren't really that interesting.

During certain kinds of driving gear shifts became.. tricky. That's when I learned how to double-clutch, something I kept doing on cars as well, for many years after (think going steep uphill on snow and then having to shift into first gear without stopping)
