That is an interesting video steve. Like you I was watching the drive gears. I tried to follow the drive train but I could not see the gears that were turning the bevel gears that attached to the main shafts. Everything else makes sense except in one close-up of the small gears outside the track frames, 2-of them didn't seem to be meshing. (Wear maybe) or possibly I just couldn't see it that good. I was also amazed in one of the close-ups at how much the bucket twisted from side to side during loading. I guess that is why the stick broke occasionally on these monsters. Nice video, I saved that to one of my favorites.
