Cat 385,
Caterpillar did build and market those machines, but they did not come up with that concept. It was an independant dealer called Peterson Bros, if memory serves, they had a book they were selling some years back. It was the engineering genious of Buster Peterson that came up with the Quad D9 and the SXS D9's, plus many other of what cat sells was his idea, I think the U blade as well. He had patents on these inventions and sold them to cat. All the controls and the way to link the machines was Busters idea.
Yeah in the good old days big companys actually listened to some of the nobodys out there. Now they don't give a rip unless you have an engineering degree.

There was a thread a few weeks ago about Peterson's genius, but this stuff sure isn't tiring for me. It's just amazing what came out of that workshop.
And yes, can we see some more of those triple 657's?

By the look of that last picture with the steering wheel up the front, would that be for the apprentice???!!!!! Seriously though there were some really unique ideas used back then, it reminds me of ag gear with a couple of tractors hooked in tandem. OH & safety wouldnt have a bar of it today. A question I have is how did the dozers hooked side by side turn? Did one completely stop and the other push it around or was it the normal way where they both disengaged the same track on each machine?

Cat-Peterson relationship.
Hello, Dozer575.
You are right about the Quad-track D9G's - the DD9G's - but not about the SxS D9's. After seeing Buster Peterson's DD9G's in action, Cat's research department approached Buster with the idea of putting two D9G's side by side with one wide blade across the front of both. Buster linked up two toy Cat dozers in a similar fashion to what was eventually adopted in the full-sized version. Cat liked the idea and gave the go-ahead for a full-sized version. Buster developed the idea 'into iron', including the single-operator control system. Cat again liked what they saw, took it over, developed it further and released it as a production design in 1969. In total, between both D9G's and D9H's, only about 25 sets of these machines were made, including the original set that Buster put together for Cat.
Ditto with the push-pull scraper concept. Cat approached Buster with the basic concept and asked him to put it 'into iron', which Buster did in a lot less time than it would have taken Cat themselves. Again, Cat liked what they saw, took it over and released it in pretty much the form that Buster had given them and which we know today.
Buster did a LOT of work with and for Cat, to the extent that Cat gave Buster their design protocols so that both companies were talking the same language when discussing the various projects. Cat sent a number of projects to Buster to put 'into iron' 'cos he could do it so much faster than Cat themselves. On the other hand, Buster developed an LOT of ideas on his own that Cat eventually took over.

Hey Deas
U put a picture in another thread of two cats with a huge ripper connected to the blade mounts on the side.
Do you have any more pics of that setup?
Is that a Double 9 setup?
History behind it?
Looked like the pics where from your part of the world

deas, on the subject of scrapers linked together, didn't letorneau do a scraper chain? I'm unsure of all the details but I was thinging he had five or more units hooked together, maybe more. I see on http://www.letourneau-inc.com/about/history.htm under year 1966 they have three pans with it looks like one operator, and one of his pans was the capacity of all three of those cats...

Hi, Stumpjumper83.
You might like to check this link for further information.

The lad did have a pretty fair imagination and if something he wanted wasn't in his toybox, he'd make it and put it in his toybox. LOL.
