I could write a book about the mishaps I saw or heard about during my days on the wheat harvest. Hundreds of combines driven by eager young men translates to plenty of interesting stories. That's why factory engineers are out there following the combines.
One of the incidents we had was when a young man on the crew was driving a 580 Lexion with a 39 foot MacDon draper head down the road full bore at night in Idaho. He was going around a curve when the end of the head hooked a guy wire to a pole holding up a big 3ph power line. The combine spun around sideways on the road and the pole came down, lighting up the night sky with a big blue flash. The young man in the combine was screaming into the mic that he was going to die while the other guys were waiting for him to quit screaming so they could tell him to just sit in the seat and wait.
To give credit to MacDon, we only had to do a small amount of blacksmithing to the adaptor to get the head back in the field again, and it spun around and stopped a 40,000 pound combine. I saw two Deere drapers bent back when one hit a ditch bank and the other a pole. The first combine hit the ditch and the combine behind it panicked and hit a pole. This stuff does happen. I dont go as far as to call someone stupid but some of us certainly are less attentive than we should be. Jim
