LOL, i wasn't going to put him on the crew!!7 years old is far too young to be 'working' on a mowing crew and the adolescent mind is not developed enough to handle any safety issues that will present themselves. It just isn't a good look. With that said, I have had suppliers with children under 15 loading supplies with bobcats. These kids are born into it and were running machines at around 5 years old on their own. I worked at a company where my boss was doing commercial snowplowing at 13 years old. His dad was able to leave vehicles on site for him and his brother to use.
