This was a good video of the bulldozer history and the mechanics of the elevated sprocket tractor current design. I was transferred to the Cat Track Type Tractor D10 design section from Cat Defense Engineering in 1976. Working as a draftsman engineering technician on the first production elevated sprocket D10 tractors, I remained in that division until I retired in September 2000. During those years, I recall doing changes and designs for production issues, assembly issues, and components. I redesigned the prototype fender to be more narrow and bolted to the rear drive case casting instead of being welded. We added skid plates to the top of the fenders and hand rails to the ROPS base. I designed the first fire suppression to be provided as an option for the tractors. I redesigned a final drive bevel gear that had a spacer plate to be a single part. I designed a ROPS base to provide a mounting for the cab and also a cross member with a mount for the cab and a firewall. This eliminated a support frame for the cab and reduced shake motion felt by the operator. I designed a pair of housings for the drive shaft to go into the rear drive case to provide lube to get to the bearing needed for that entry. In 2000, I was transferred to the pipelayer design group. We designed a machine with a hydraulic lift cylinder and a counterweight that opened like a door that did not go into production due to the hydraulic cylinder allowing a "drift" that did not keep the pipe from moving slightly, that is necessary for welding the pipe joints. I later worked on Custom Shop tractors, mostly land fill machines, that required modifications to keep wire and other debris from entering the engine area and the sprockets. We also designed and built pipelayers modified with engine and hydraulic tank heaters for use in Siberia operating on the permafrost at temperatures around minus 40F. Some readers will know that bulldozers are the Cat product most identified but there was a huge range of equipment, engines and transmissions that evolved from the beginnings of the Holt and Best merger that became Caterpillar. I hope this is interesting to the gearheads/designers, factory planners/assemblers and will add a link to a few of the remaining designers and technicians from the Cat Track Type Tractor engineering people I have contact with.

[@Mfurze90]

A fruitful career. I hope you know in your own way, that you changed the world.

[@dieseldemon8562]

Good evening! That’s quite the career, and what I have in mind for my career path as well. I work in a Caterpillar Rebuild facility, and a lot of the innovations you designed allow us to rebuild these machines to like new condition in a relatively short time span. I’ve always been intrigued by the research and development, and engineering aspect of the tractors. In fact, a few weeks ago a coworker and I were in Hydraulics class in Irving. By the third day, I was known for taking the class off on tangents that went much deeper into theory than the scope of the course, and often resulted in us digging through schematics and enlisting the help of another instructor to find the answer. One of our classmates asked my coworker “Is he always this inquisitive?” My coworker replied “Yep. We don’t let him in the component shop anymore. Not after finding him counting the teeth on the gears…” That being said, I’ve had a few ideas for product lines I’ve thought about bringing forward. This would be a different application than what Caterpillar is known for, but I believe the powertrain systems hydraulic systems, and even existing product lines could be utilized to be very competitive in the industry.

That’s how I love to think of these things. Some great beast. If a car is a modern horse then this D11 is a dinosaur. Makes the thought of the remote control ability shown at the end all the more unappealing. Riding a dinosaur is always more fun than just telling it where to go and what to do.

Fabulous. Spent some years up hill and down hill clearing and leveling, cleaning and harrowing, land development, on a D6C and memories of that season will always remain. Magnificent machine.

[@danielpullum1907]

Enjoyed the look at the D11. I had a great experience back in the 60's when CAT was trying to upgrade the D9 into a bigger machine. They built the SXS D9's with a 20' blade across the two D9's. I got to drive one at a strip mine in west-central Indiana. They were spreading topsoil back on the spoil banks after they were leveled. The operator sat on the right machine. The machines were connected by 64 wires that transferred the control inputs made by the operator. It was a little light in weight to handle the 20' blade but with finesse it worked pretty good. WOW what a ride!!!!!!

[@LordGizmo]

Awesome story man! It's crazy how a 20' blade is something that can be upgraded on. Most people don't even realize how impressive these machines are until they step in front of one.

as some one that knows nothing about heavy equipment i just have to say cat makes the most beautiful equipment out there. if i had a dollar for every hour i spent sitting on the side of a hill watching cat two engine scrapers being pushed by cat D10 s i would be rich. i have been watching cat machines working all my life, from a little boy selling lemonade to the operators ,to working for a rail road as an electrician maintaining cat generator sets and locomotives , to now retired at 75 looking on the internet at them. i still get goose bumps seeing and hearing the roar of power from that screaming engine under load and the ground shaking under there massive weight . i love it and now seeing them being put together is just great. thank you for this video ,

[@buckwheat7424]

i rode a D65 E kamatsu dozer straight off a 35 to 45 feet inverted rock vertical. landing on 2 light loads of topsoil that i pushed off a minute before under that load was solid rock. wearing no seatbelt, i was equipped with a ROPS that got bent down to the operators seat. the tractor turned over 1 time and landed on it's top, then sprung back over on its tracks. the dozer was running wide open and in second gear and wasn't moving, except for the oil that was blowing out of the turbo that was separated. what my injuries were: a severely burnt palm of my left hand ( had to of been from the smoke stack quite a ways away from the operators seat, my back had scratches around my belt line. my face and forehead was pack in dirt. no injuries that kept me from getting back up on the hill on monday, it happened on a friday. i was attemting to leave a pile at the edge of the top and then to push it off with the next load, the owner of the company was standing far enough back to start waving me to push it off, i did and nearly crapped my drawers when i sluffed of the dozer blade. i backed up and pushed a second load also starting to back up, and owner was waving me to push it off i did and when i put it in reverse, i must have hit 2nd or in between gears if it's possible, and let off the decelerator and it was in slow motion going forward by the click of growsers or what the track cleats are called, "click, click click slower that 1 second intervals and as the idlers were nearing the edge i froze and squeezed the clutches while screaming "im gonna die" over and over. i was 18, iwas the loudest and roughest thing i've ever been in. i had to of missed me by inches, i ran out of the dust cloud and went up to owner and said "well it doesn't look like you need a operator like me, he said he couldn't believe i wasn't dead, and he ran up and shut the dozer off. i had never worked in the hills before, only in the flat lands with fills no more than 5 ft, pulling a vibratory sheepsfoot. and if you want to change directions, you didn't need the brakes because the roller stopped the tractor immediately. to have corrected the fall all i had to do was put my foot on the brakes. i didn't know about that. monday moring a 988b was loading 40 an hour the owner said if i don't get up there, i might develop a fear for hills and never be able to do it again, and i wouldn't get less than 4 piles away from the top edge, the insurance totaled the dozer and the loaner dozer from kamtsu was with street pads and a four in 1 bucket, with no seatbelt. but brand new tractor and rops of course it was around 1979. i went on to a full career running scrapers, 666's 657's, 637 was my specialty, rough but they'd go anywhere. . in the hills of sounthern californa iuoe, didn't file any kind of injury lawsuit, the owner took me to the hospital and in a couple of hours i was getttin a ride back to my truck. sittin in a deep seat, both feed flat on the floor with a far away look, i was a dirt diggin mofo.

I found the reason for Cats success is the quality of the steel they use and cat8 bolts in every joint. Especially the fluid filled track units. When overhauling the cat tracks you saw the quality in every part that l think it’s the reason they continually last Longer than other tractors. Also spares and service is good which ensures longer life of your machine plus the fact their still working while other makes haves disappeared.

You're not wrong! But, as much as complication can be troublesome, it's worth noting that experience is how things are made to be reliable to the max. 100 years ago, a jet turbine would be considered impossible to produce to any real degree, but look where we are today. You can look at the progression from muskets, to breechloaders, to machine guns. Time shows that the more research is done into any one thing, the more reliable it'll become.

[@edwarddentino6062]

If you can find a photo of the D10 on display in front of the Track Type Tractor building SS in East Peoria, you can see a cabinet on the left side fender. That contains the first fire suppression system put on a bulldozer. It is very simple. A halon bottle with two hoses running into the dozer. One is into engine compartment to deliver the halon. The other is from the actuation valve into the operator compartment where there is a nitrogen bottle sitting on a shelf behind the operator. When the operator pulls the release valve handle on the nitrogen bottle, pressure from the nitrogen goes to the halon valve and the halon is released. The reason this was installed and became an option occurred when the first prototype D10 engine caught fire at the build area. Probably the new systems are actuated by a solenoid with a switch or button on the operator console.

I worked in the Aggregate and Ready Mix industry for 20 years. Beginning in the lab and eventually operating Aggregate plants. We were given the freedom to learn more and more equipment as time went on learning from the "Oldtimers". I always enjoyed my time on a dozer. Starting with a D-9, D-10 and eventually the D-11. Ripping and pushing went hand in hand with the D-11. I wasn't impressed with D-11 when I first operated it, it seemed sluggish, I later learned it was slow acting compared to smaller dozers but had lots of torque for working in the pits. My favorite dozer was an old D-9 open cab w/ROPS it was so versatile. And so reliable.

When working with autonomous dozers we have to have a special designated park up area away from the main " go line " and our work area's are also restricted for safety. We are also required to carry a remote device called an " A-stop (its a remote control) " that allows us to kill the dozers with the remote if we need to.

If you build it, they will come.

I, and many others I’m sure share this thought, but I’d absolutely love to see how the shay engine that pioneered the American timber industry in the late 1800’s and early 1900’s. before the shay locomotive engine, with its, for lack of a better word, ALL WHEEL DRIVE, the virgin timber that was before out of reach because of its location commonly being too far from the streams that were large enough to float the large timber to the mill. Thr shay revolutionized the American timber industry. Ephraim shay was a logger himself and he recognized the need for such an engine so he made it happen. Without thr shay, America may not have become the superpower that we were in the 1900’s. It’s a wonderfully magnificent piece of history that I’d love to hear more about. Hopefully yoy see this.

Most insightfull thankyou for pointing this comperlation together for the peoaple who are potentially planing to use this style of mashean although the cost must outway the task that is intended for the use of the tractor carefully planed the outcome can benefit the contractors before the purches of such a luxury again thankyou for this display of such a wide range of tractors you have available to the public I look forward to your next instalment and eagerly antisepate the new and exciting tecknolergys coming up in the years to come as technology is coming in leaps and bounds for the ease of the operator so it will be more cost effective in times where the cost of such mashiens must be taken into account before planing to outley the cost of using THEASE sort of tractors

Your new videos are MUCH better

[@4thgenfarmer371]

It's a bad ass that's for sure. And for $4 million you could have one too

[@jimkillen1065]

Yea the D11 has a lot of power. I operated on in a coal yard . It was hauled in and assembled. . It had a ladder mounted on it to make it easier to get to the cab . The one I operated was not diesel electric.. to be honest it was fun to operate , especially after you learn how to make it do what . Pushing coal out and making a lift or pushing in to reclaim.

[@livingadamman7994]

Awesome !

[@josh33025]

Triggered by the blade being called a bucket, goodbye.

[@deany53]

amazing stuff

[@MisterFurious71]

A D11 is a lot wider than 11’ 10”.

[@Trucker1970]

I was looking for this comment! A U-Blade is 249.6 inches wide or 20ft 9 inches wide.

[@austinrayblackwell1119]

Yea maybe for a D6 lol

[@titanary68]

The last one I hauled was 149.8” wide outside of track to outside of track. We haul the blade separately and run it front to back on the trailer as some blades can be 300” wide

[@406living9]

Just looked it up it’s around 20 feet wide on The standard U blade

[@LesCamionsDeThomas]

Great job good video thank you!

[@Homefree18]

I have 12 year’s operating the D-11’s the new ones are really quiet nothing like the older rattle traps 😁 I’ve made roads, ramps, pushed on dumps, landscaping pushing over 15” diameter trees like twigs, pushing snow piles higher than the blade and of course ripping up frozen ground. After awhile you get so use to it you don’t need a anything telling you what percentage you are going up or down 😊, I watch the new employees operating them and just shake my head, they can make a hole in the ground fast if you don’t pay attention to where the blade is.

[@matrixist]

Cool machine, but the WEF will want you using hand shovels in the future.

[@pflqr]

If it ain't a CAT it's a dawg!

[@markmathews6876]

where is Bob Le Tourneau , you have half the story

[@bobnwashington]

R.G. claimed to have been the 1st. to attach a blade, Holt used them as tractors. R G used electric instead of hydraulics.

[@OUSSAMAGUEDOUAH]

Wow very very nice technology ❤❤❤❤❤❤❤❤❤❤

[@kennethconnors5316]

outstanding video , covered the subject to a "T"

[@USAR8888]

Crazy to think just the idlers by themselves are 1 ton each! What a beast

[@pepedrat2982]

Holt purchased the patent from Hornsby. Even the name Caterpillar was coined elsewhere. Being honest doesn't detract from the success of the company.

[@DebbieSuttle]

I like to see eskavators and dump trucks if u don't mind but I like this video too 😊
