Amazing excavators at work, trucks, loaders, bulldozers in action, transportations, cat - caterpillar, Komatsu, Liebherr, Volvo, working and digging in mud and mines for coal. Awesome video!  I want to see them change the bucket teeth on one of these. I bet it pretty much takes a team.  Give that machine a break!, wash it out, grease it, change the oil and filters and send it back for duty!!!!!!  the views, interior and exterior are not the same shovel, bucket teeth are longer (outside view) !!!! .  Immediately bring 1000 of these to the south  border,  and all necessary equipment to make that border impassable.  Go deep 200ft x 300ft wide.  From Calif to texas.  No wall needed,  just get this equipment  down on that border  Caterpillar - please get your act together.  This beautiful machine is painted Cat orange, it wears Cat insignia but the operator's screen says Bucyrus - how much would it cost to get that RIGHT
