Somewhere in this fourm someone posted up pictures of quad teams of D-11 and even one team of 6 D-11 linked together with one cab and one blade.

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.

Thanks for the corrections.
Wow, and years ago at an auction there were 2 quad units that were here, one set was D9G and the other was D9H, I think it was Fiorito constructions machines, they used to be the biggest outfit here for doing hiway construction, and they got the job done, unlike the ones we have now.
Yeah remember as a youngster when they were widening I-90 there were lots of machines on that job, they even worked a grave yard shift, at least I think it was Fiorito that did it. We have had PKS in the area doing things but they are slow. And hit the jobs with only a hand full of machines.

I ran a quad 9 for western contracting in 1967 while working on a huge fill south of Gorman California on I-5 project. They were hooked end to end and controlled by a wobble stick.

It had controls on both tractors, it was a great push cat and you could roll the biggest boulders out after a blast for the scrapers to rap around and pick up. No ripper just a push blade.

I have several pictures of SXS's and other D9H's with company built blades on them. Have to figure out how to post them though. Company is Russell & Sons Construction out of Kansas and Texas.

Quad D9's with Collins ripper.

Hi, MKTEF.
I don't know anything about the development history of the Collins ripper shown on those DD9 'quad' tractors. All I can tell you is that I have been told that it was developed to service a need for deep ripping to break up hardpan subsoil in various areas of California. One of these areas, I think, was the Napa Valley which, amongst other things, produces a lot of grapes and mucho wine therefrom.

I have done several searches on Google for "Collins ripper" but, being an American search engine, it only wants to return results relating to baseball, basketball, gridiron or wrestling. It doesn't seem to comprehend that there is life outside of the subjects. LOL.

Maybe some of our Californian readers can come up with more information.

Collins Ripper

Deas, as far I know from the book "Cat D9-D9R", a German publication, the Collins Ripper was manufactured by the Peterson Tractor Company. Further, the book mentions a weight of ca. 16 metric tons of the ripper assembly and more then 1 ton for each shank.

 

[MKTEF]

Well guy's i spent some time at the Peterson tractors site and found this:
http://www.petersonholding.com/about/towable_ripper.htm

Seems like Peterson build the towable rippers first. Real huge.
Theres a note to the Central valley.
The same customer later used the quads to do the same work with a ripper at the back of the quads.
Dosent show any pics of the quad rippers though.
But the result was the same, so they got to be as big as the towed ones.

Bet there is a connection here. That same firm might be in the picture u got Deas.

A lot of interresting stuff on that site.....

Collins ripper.

Hi, FatCatGotHot.
Thanks for that. It would make sense that Peterson built it. It was certainly an innovative way of setting up a larger style of ripper on a tractor not originally designed to carry such a beast and innovation was Peterson's hallmark.

Hi, MKTEF.
Thanks to you too. Buster was certianly one very inventive gentleman. He quite possibly could have got himself off a desert island with an elastic band and a paper clip. LOL.

I think it was Fiorito constructions machines, they used to be the biggest outfit here for doing hiway construction, and they got the job done, unlike the ones we have now.

Back in the day when I-5 and I-90 was under construction, the road contractors list read like a cast from the "Soprano's". Fiorito Bros, Scarsella Bros. and at least a half dozen more I can't think of due to oldtimers disease (all a great bunch of guys). I was wrench'n for NC at the time, more work than you could shake a stick at.

Quad D9

Back in the day, 1969, Peter Kiewit was building Dana Point harbor and I was running a 3 speed stiff neck 651. We were being pushed with 3 D9G's, of which one machine was an inline Quad 9. It was run by an old black guy named Riley Brown. We had a long cut with a pit boss and the 9's would back up and the scrapers would pull in front. At the time the power was awesome. A few years ago I was running a new 657E for Independent in Santa Clarita. We usually hooked up, but once in a while we would work with D10R's.
Want to see real power? I will try to attach a photo I took from my rig showing a 657 being loaded by 3, yes 3 10T's. Note the ripper assemblies with pushblocks. 3 10T's + 1 657E = 600,000lb+ and 3000hp+. This is how to move dirt!

 

[Gavin84w]

Look forward to it HKTOM, i think you have to have afew posts up before it allows pics so keep postin them stories. I have a pic of 2 84W D10,s working with a 666B so that would equal about 2350HP on the cutting edge. Scrapcutters, i mean welders love that stuff!!!!!

 

[JTL]

These are the only ones I have. Took these a couple years ago at Scarcella Bros bone yard in Lind, WA. They were still there 2 weeks ago. Im thinking its the only two pair left in my part of the world.Another supe for the company I work for now was one of the last guys I know of to run #22, about 15 years ago. That was on Hiway 395, just a few miles from where they are parked now. I could be wrong though!

Triple push 657 + more....

Hey guys, pictures from the seat of an Independent 657E at Santa Clarita. Note the 10T's triple pushing . They were primarily loading 51's but a couple of us had to squeeze in there to get an 8 second load. I'll also post some from the seat of a 660 pictures on the 660 thread later.
