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 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 miss the D9k. It was awesome.
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
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 🙂
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
All they ever needed
Let's see them run on battery alone like a tesla😂
