The gap between the ecobabbular subtitles and the brutal ripping apart of mountains by vast machines of great power is comic, for those with a sense of irony.That grader needs a bull blade on the front, so it can at least have a 1/2 way level surface for the front wheels, I had one on the grader I operated , worked great ! What I am seeing here is nuts.These excavator operators are truly masters of their craft! Building a road on such a steep mountain requires great skill and concentration. I can't believe how they handle such difficult terrain.
