Randy did speak for himself and posted pictures and detailed explanations and apparently you can't except that either.
Randy was employed by Caterpillar as a Motor Grader Product Evaluation Engineer along with Don Hess. He also went out with the very first 24H to demonstrate and train operators. Do you really think Cat would send some hack out with their very first 24H worth 1 mil+. He also has patents on graders. There is 90 years of experience alone with just the 3 people listed below who worked on Caterpillar graders. If that's not good enough for you, then sorry I can't help you. Nobody can! Being in denial because you've never done it or don't think it should be done doesn't mean it shouldn't be done. I don't think you have to be an operator to be able to tell who knows what they are talking about. Next your going to say an excavator bucket can never be turned around for odd applications. Funny you haven't disputed that motorcycles had a 24 hour race when temps. reached below -40C. Yeah, I posted that too. Does that make it false? Quit looking for fault just because I posted something trying to help someone with an inquiry.
