I don’t get why these walk arounds don’t get a lot of views, there often the perfect length for lunch break and it’s always something really cool or even better something I’ve never seen before.
I've always been amazed at how many things you could put on/behind not just the D4, but also the D2. They really made these poor tractors work back in the day, and it's fascinating to me that those engines could move all that weight.
Engine's are torque monsters with gear drive, riding down rails on rollers like a train down the track's. Pretty Simple. Generally, they'll push what they weigh and then some depending if they're going up hill or down hill..either way, that's pretty awesome!
Here's a color i'm very familiar with. Several of our old pieces of equipment were sourced from old US military bases here in Europe. Some got repainted in more traditional colors (red, blue) but most retain the military green.
Excellent video that crawler has lots of extra options it was possibly part of the sea bees that built roads and bridges and was able to keep the lines moving with the extra winch to pull trucks out or what ever needed to be done . Keep up the great videos
I have a Killefer tumblebug just like that one. Been on the family farm form 80 plus years. The wheels allow carrying the load over a distance with out dragging the ground. It will move a lot of dirt once you master the two rope trips, one to raise and lower it , the other to set blade to cut, to dump it and hold it in dumped position . A IHC TD 40 and TD14a pulled it great, my D4E SA pulls it will power to spare. Fun machine to use
As much as people like to argue about who had the best tanks, guns, planes, ships, etc., the war was actually won by the side with all of the bulldozers.
Very nice looking crawler complete with the LeTourneau “Tiltdozer” those cranks on each side of the blade are used to tilt the blade to one side or the other, and if both were cranked the same amount one direction or the other it would change the pitch as well. That is one heck of a tumble bug!! Wow 👌👍
Another great video Toby! 9 years ago I was riding my quad way out in the woods and found an old d4 that was cable run just wasting away. From what I could see it through a rod because there was a pretty big hole in the block. I would love to see that tumble bug on the back of a rd6 getting loaded up. Cheers
What a true American 🇺🇸 built iconic US Military service machine still serving today showing us how it use to be done. Thank you for your knowledge & sharing the video.
Perfect for building a runway on that newly captured Pacific island! Do you know if the used D4 or D6 to build the Alaskan highway during the war? Lots of good footage of that on RU-vid.... but I'm such a newbie.
They used everything they could scrape up and get their hands on from older stuff from the 20’s to brand new machines to build the ALCAN that includes D2’s, 4’s, 6’s and 7’s and pretty much every make model, brand and size of equipment built at that time. It was was a collaborative effort with civilian contractors and the military so contractors brought whatever equipment they had and the military supplied the rest. However the primary dozers you see in use in that old footage are military owned D7’s with a few D6’s and D4’s scattered around here and there. The reason for that is the speed and urgency of building that highway called for the biggest newest most powerful and reliable equipment available to get the job done. If your interested in learning more about the building of the Alaskan highway, I highly recommend finding a copy of the book, the trail of 42 a pictorial history of the Alaskan highway by Stan Cohen.
Toby I have a photo I would like to send you. You did a video from a recent show on the “highly inefficient” hydraulic blade kit made out of Los Angeles. It’s an old photo of a couple of loggers running a similar setup in the woods in the mid to late 50’s. Also great stuff on the cable control gear. Thanks again for all you do from a young (ish) cat skinner, no small part of what I know about how to (properly) run cat is from my watch minutes here. Out here on the log truck trailer reaches we call that pivoting articulating hitch a compensator
Dude. I love your mechanical content but these walk-around videos are AWESOME! I don't know how much viewership you lose but I hope you keep em coming. Really enjoy them. Thanks for the videos
Coincidently I just recovered the same military D4 with the same cable lift. So cool Of course mine is rusted solid for now. Love your walk around vids
5:35: I was just saying to myself, when you signed off, dang, I wish we could have seen it work. And then, voila! Thanks for that little video epilogue. That meant a whole lot.
Hey up mate hows the eyes doin and thanks for the walka round stuff that i enjoy. Went for my eye checkup today which was good and asked so next eye is this Saturday rather than another 3 weeks cos on of cancellation love the stuff you do and say hello to mum ad dad from me
Love seeing military tractors and crawlers. Americana all the way. Which reminds me, I have a friend who is looking for a fixer upper military Willys Jeep, WWII to Korean War era, if you run across one. Keep those walk around videos coming!
With all the eye candy at that show and the interesting walk-arounds, I am surprised nothing followed you home from there. BTW good luck with the eye issues.
Thanks for the video Toby! That was a great piece of history there and glad I got to see it. The best part was the manual they have for it as well. Thanks again!
Excellent informative video as always 👌and the bonus footage of it all in operation 💪 is the exhaust on the D4 a standard muffler or is it a spark arrestor 🤔 have seen spark arrestors that looks very similar 👍
Beautiful little D4. Though I'm not a fan of the blade manufacturer. After working on their coal scrapers and a couple of their cranes I shudder everytime I hear the word LeTourneau. The inventor of their 3 leaf and 7 leaf switches is the bane of my life.😒
Very cool! So… it’s only the members only notification’s I’m not getting… since I check the page everyday not a tragedy, but you’d think RU-vid could do better
I remember the watching the John Wayne Film "the fighting Seabees" as a kid . Daft question would it have been yellow first or green , yellow then green ?
I have a similar one. I have an r4 and I was wondering if you have any knowledge of the transmission and does it have a dipstick? If so, would you be willing to share the specs? Thank you
