Not really the same thing but, when I was around 13/14 and it was time to bring in the hay, I was a shuttle driver.
That is I would bring trucks in from the fields loaded and drop it off at the barn and take an empty truck back to the field. It started with pickups that I was allowed to drive but then I would just jump in whatever was empty! So it was usually an F-250, F-350 and an F-600.

Big stuff for a 13/14 year old kid! And I got so I could shift as good as any adult! To jerky a take off meant bales falling from the top and the guys loading would bitch, so I made sure I learned how to be smooth!!
