Stop in for a cup of coffee
Has all the earmarks of driver dozing off! Hah. One of my guys did that and I had a hitch behind the seat. When he dropped off into the ditch and stopped abruptly the hitch flew to the front lacerated his ear on the way by and blew out the front window. I solved that by having the GPS alert the fuel shutoff if tractor got 25 ft beyond field boundaries. Guys fall asleep during harvest as the cab is warm, it is night time, and they often have not slept a good nights sleep in days. Harvest is hard.
