Russell & Sons Construction Company of Longview, TX, took the SxS idea to its ultimate form in 1976. They modified one of their two SxS D9H sets so that the right-hand tractor was offset 11 ft. behind the left-hand machine, and equipped it with an enormous 48 ft. 8 in. long, variably curved angle dozer fabricated by Balderson. The dozer alone weighed some 27,600 lbs. plus hardware. The curvature and angle of the blade was designed to move the most material possible to the side with minimal resistance, and working in passes up to 70 feet long it moved 14,210 cu. yd. of overburden in one hour in 1977. Named Double Dude, the massive machine has been retired for some years, and Russell & Sons has restored the blade as a unique billboard.
