This video which I believe originates from Croatia, features 3 classic O&K excavators, with two of them working away to topple a massive piece of slate rock in a quarry on the edge of a hillside. Of particular interest is the old RH25, which incidentally is sporting an unfamiliar colour scheme, at work in the quarry floor as it tries to assist a newer looking O&K model, possibly an RH9, which is levering away at the rock from the top. As the massive slab comes tumbling down the RH25 has a lucky escape as it lands just metres away from the slowly reversing machine.
