This was the video I was hoping for George .besides the tow vehicle or team of horse's...could one man operate all the controls of would it take two men ?
Not trying to answer for George here, but I have spent some time messing about with one in a static situation, so I'll share my opinion.
I think it would best be operated by one man on board the grader itself, as two would very much be in each other's way most of the time, and might well find themselves working the controls to cross purposes. Certainly if there was more than one aboard, there would still have to be just one "captain" in command of what adjustments to make, and how and when to make them.
Makes logical sense, thanks Daniel 😊
Perhaps I should add, that once the "cut" was decided upon, and the blade and frame adjustments positioned for it, which would likely be done while not moving, then once under way most adjustments would consist of minor fine tuning as the cut progressed. Any major repositioning would likely be very difficult (and slow) while the components were under load during operation.
I think this is where I have to disagree with you Daniel, having worked with large equipment all my life I beleive constant adjustment would be normal...cut ins for culverts, driveways, curvature of roadways on hillsides vrs flat ground....ect. I doubt that adjustments (even for Manuel equipment ) is very difficult while in motion, plus they were expected to work hard 100 yrs ago 😊
