Bingo, you don't let a illegal with a 4th grade education behind the wheel of a 300,000 dollar combine.
No you don’t. It takes someone that has had the proper training and experience. I know that my dad didn’t just turn me loose on his tractor without letting me sit with him on it and drive it for little distances until finally he was confident that I knew how to operate it and then turned me loose to do the plowing, etc..
