That was Buster Peterson at the controls with the silver Hardhat.. he owned a Cat dealership in California in the 60s and 70s and that was when they were undertaking the massive job of building the interstate system in California at that time. He not only came up with this idea but built the first prototypes in his shop in San Leandro I believe. He also built the side by side D9s with a blade wider than 24 ft. All of the retrofit's were done right there until the big wig's at cat saw the massive power and potential and started producing them on a slightly larger scale.
641??? That's old. I'm old, too. I've never seen one not in a pile. Did it have cable operating systems? I'm familiar with cable dozers and scrapers, not the 641 system.
@billortloff4215 They were hydraulic. I believe they stopped making them in 1968? Oh boy were they hwll to run. 28 yard can with a 3 speed, hardneck (no cushion ride) and always breaking down, but that company got their money's worth out of them old beasts. I was elated to run a 631 after that experience.
I can remember when they were building interstate 88 watching them pushing double ender pans through blasted rock four diesels screaming rock and steel scrapping, it sounded like godzilla screaming in my ear .
The D10 changed the world. Period. What a machine. First elevated sprocket machine. Ran one for yrs. D348 engine. Could listen to that hum forever!

very cool. being from oakland, it’s nice getting to know stories like this about the area i grew up around.
I would argue the Komatsu D335A is more famous
We had one for a short time because it couldn't catch the scraper. The scraper had to come to a stop.
I ran 641's here in Alaska and we had a quad pushing us. Man that thing was powerful, especially in a curve.

@@Pals777 Thank you. I love knowing how construction worked before me.

You bet. Happy to share
Great push cat(s) but they are murder on tracks. I was an apprentice mechanic on a PKS job that had 2 of them pushing 651b's
I wish torque was mentioned too because torque says way more about how powerful this kind of machines are than HP.
Lmao i thought he was talking about killdozer at first thats the most popular bull dozer on the planet.
In the U.S. maybe. Not many are aware of Marv's adventures outside of America I guarantee 🙂
I miss the D9k. It was awesome.
That's a big 🐈

Old CAT TECH love these machines have run D 10 AND D11 NO JD JUNK HERE
All they ever needed
They should have NEVER changed the logo. 🙄
I have never seen one .

Let's see them run on battery alone like a tesla😂
