Don Hunter's Holt tractor

Don Hunter's Holt tractor is a replica of a 1906 steam-powered crawler tractor. The only original part is the crankshaft; everything else Don scaled to size off some drawings and some pictures and manufactured everything else, except the boiler.
Don started this project after he retired. It took him roughly 8 years to complete (correction to my data at the end of the video)
