Karwik, a builder of some beautifully unusual vehicles, is back with another two for your delectation. The tractor is a Mazur D-50, an odd enough vehicle on its own, but when fitted with a cable-operated-bucket-scoop-on-rails* it becomes easily one of the most bizarre construction vehicles we’ve seen. The Elves, who are themselves a little odd, love it. See more on Flickr. (*We have no idea what it’s called!)

Next up in today’s post of unusual construction equipment is an armoured bulldozer being driven by a cat. No further explanation needed. See more at Lego Junkie‘s photostream.
