Grading story fer ya.. One of the graders I ran, a 740 Champion, had a float function that was electrically controlled. You had to flip a separate toggle switch for each side of the blade. They were twitchy and I didn't trust them at all. One guy did though, the infamous Frenchie from my fishing trip post in the 'what did you do in the shop' thread. He had the moldboard on float and flipped the switches off at the end of a run while he was still moving pretty fast. He had the Detroit Diesel engine screaming along wide open and yanked back on the levers to pick the moldboard up. With the revs pegged high like that the right side came up flying up but the switch for the left side didn't work and stayed in float mode, which disabled the lift cylinder. He buried the left side of the moldboard a foot deep in a brand new road and made a hell of a mess. It was on a road I took to work and I drove past the lumpy repair scars twice a day for years afterward. Frenchie wasn't very tall and he liked operating standing up so he could see better. He slammed into the steering wheel pretty hard when the grader came to a sudden stop. The bruising on his abdomen and chest looked like he'd been in a bullfight and lost decisively. They didn't let him operate graders after that. Wasn't just that incident. He had other competency issues. Like the time the road super found him with the grader completely sideways on a busy road ramming snowbanks into a cornfield. He had vehicles backed up in both directions for quite a ways. Exasperated people were turning around and some of them backed into the ditches making 3 point turns and got stuck in the snow. The foreman said it was slow motion bedlam. Lots of complaints from the public and some made it to the county engineer's office. Didn't go over well.
