What a lovely machine. Can go places goats can't get to; and dig like a wild boar while its there. This thing must depend on its hydraulic fluid like a human depends on blood. Its circulatory system is probably slightly less complicated than a human's; but I'm willing to bet its far more effort to maintain. I've seen an excavator break its arm while digging. (right behind the upper hinge; they welded on gusset plates all around on site and kept working.) I think this kind of machine would shear wheels off long before that; I wonder about how they've balanced the pumps and whether there's governors to keep it from breaking itself.
