My wife and I felt like 11 was a good age for my son and daughter to start learning how to drive a tractor. Actually, my daughter might've been a little younger than that, but she's always been more focused and mature than my son. I was always with them though. That might seem too young to others, but we based it off of our area where it isn't uncommon to have your kid manning the tractor by age 7. I'm curious as to what others will say.
