Amazing excavators at work, trucks, loaders, bulldozers in action, transportations, cat - caterpillar, Komatsu, Liebherr, Volvo, working and digging in mud and mines for coal. Used this monster before in a site formation job!  Glad to see this again.  When you said huge stone. You meant it. Damn, that stone was persistent!  Fun fact:   Caterpillar doesn't make a militarized version of its dozers.   All the military does is add thick glass and better enclose the cab.  Everything else is fine the way it is.  Caterpillar is the most excellent work machine brand among the others..........  LOL! Huge rock be like: I've sat here for millions of years...and I ain't budging now! Dozer operator be like: Jog on tinkerbell; I've got work to do!  We have equipment and we have D8 and D9 dozar and there is no any camparezing between them
