I’m sure there’s probably a law against falling head over heels for a tractor, but my goodness, if the Hornsby Chain Tractor isn’t the most beautifully Steampunk contraption that was intended for farm use! (Well ok – there are some very nice traction engines too, but just look at it!)

You’ll find a slightly larger version of the above image here, and you’ll find history of this worlds first tracked engine (1905) on this page. Amusing that they the idea on quite cheaply to the American company now known as Caterpillar! And lastly a picture that someone took of a scale model of a Chain Tractor at a show. Thank you very very much DerGolgo!
