The National Pike Show site has a thin layer of dirt on top of an odd type of crystalline rock. At the point this video was shot, there is (was) a rock ledge which interfered with operations. This August, one of the members brought a suitable tool, and resolved the issue. The Euclid C-6 is half of a TC-12, with a single 6-71, and no articulation. As a "baby brother", it doesn't get as much respect, but as seen here, it's a formidable machine, with the advantage that you don't have to split it for transport. It's interesting that this C-6 has a cable blade, but both blade tilt and the ripper are hydraulic. There will be more video of the Northwest 6 dragline.
