Cool, this reminds me of one of the old times I worked with that told me they used to run 2 D9s one behind another. Only the front one had a blade and the second was more or less just a push cat. The operator would operate from the front one and air lines would run to the second to synchronize the controls. Any seen or have pics of a setup like this.
Dozerboy, that would be a DD9 G or H, designed soley for pushing big scrapers like the 650, 651,660 or 666. One operator ran both tractors, it was built to minimize the time it would have taken to synchronize 2 independently operated pushcats these big scrapers required. If needed they could be disconnected and run independently of each other, if job conditions required it. Nowadays, a single D10 or D11 can be fitted with a cushion blade and accomplish the same thing. DD9G=770HP DD9H=820HP They were originally developed by Buster Peterson of Peterson tractor in California, and eventually the patents/rights were sold to Caterpillar. he also developed the SxS D9g, two tractors hooked together side by side to a common blade for reclamation at strip mine sites. Although these are pics of models of the real thing, it shows what they looked like. One was built, by Balderson I think, that required a third tractor to pull the blade, 48 feet wide! alan627b SxS DD9G http://www.toyline.com/bri/pictures/EMDN098.JPG Late 40's double D8's http://www.toyline.com/bri/pictures/EMDN065.JPG DD9G's http://www.toyline.com/bri/pictures/EMDN065.JPG Balderson Double Dude http://www.toyline.com/bri/pictures/EMDN113.JPG 3X D9, 48 foot blade http://www.toyline.com/bri/pictures/EMDN135.JPG All models available from Buffalo Road Imports http://www.toyline.com/bri They Ain't cheap!
