This black & white educational/promotional film is about the medium Caterpillar tractors D6, D7, and D8 models, most often configured as bulldozers (but also sold in other versions). This is circa 1946. The D6 was also available in a military version classified as the SNL G152. The D6 started out in 1935 as the RD6, fitted with a 3-cylinder 45 hp D6600 engine. The RD6 was renamed D6 in 1937, and updated in 1941 with a D4600 engine of 55 hp (drawbar) and in 1947, with a D318 engine of 66 hp. The D7 and D8 were first manufactured in 1938.
Titles: Caterpillar Tractor Co. presents Boss of the Bulldozers (:06-:23). A truck drives a bulldozer down the street. A bulldozer is backed off a ramp onto the ground. The bulldozer drives through brush towards a tree. The bulldozer drives behind a truck across dirt, it then backs up quite quickly. A bulldozer, a D6, pushes muddy dirt over. A D8 angles down the dirt. Dirt is pushed down a hill (:24-2:49). A D7 pushes down trees. Brush and trees fall over. The bulldozer pushes the dirt with a force. The dirt is pushed into the fill. The bulldozer pushes giant dirt piles over with ease (2:50-4:13). The bulldozer pushes dirt and moves at a slight angle. A bulldozer is shown from behind leaving a clean path behind it. A pile of dirt and a tree log are pushed over to the side. Brush, dirt, and small trees are pushed over. The dirt is moved with ease as the blade slices through. A bulldozer goes down a slight hill, pushing tons of dirt over. The road is starting to take shape (4:14-6:16). A bulldozer pushes tons of earth down a hillside. Everything is pushed as the bulldozer pushes forward. The strong blade is well braced to push through and show its power. Dirt is pushed in a few directions and then a big tree is toppled. Another bulldozer carries a steel rod, drops it in the dirt and then covers it. The driver adjusts the blade. Dirt i pushed over the hillside. The left side of the blade is lowered to match the right side, the driver pushes on. Dirt and brush is pushed over (6:17-9:34). Bulldozer goes down a hill, raises its blade to climb a steeper hill. The blade is dropped down, the driver looks down. Using a wrench, the driver adjusts the side of the bulldozer, on both sides. He removes a pin. The front of the bulldozer is removed. The D7 is brought to another blade to hook that one up. The driver uses a wrench (9:35-12:01). The bulldozer picks up the new blade, drops it as a test, and raises it again while turning the dozer. The bulldozer pushes through some dirt. The driver reverses the angle of the blade by hand. The dirt is pushes slowly to one side. A bulldozer pushes through dirt, brush, roots, and rock (12:02-14:47). The dirt is pushed high with the blade and constantly forward. The bulldozer continues to move forward. The bulldozer creates a small route to continue on. A small tree and dirt are pushed over. A large tree has its roots sliced on one side and then the other. The large tree is then pushed a few times before it finally topples over. Bulldozer pushes dirt out of the way as it climbs a hill. Bulldozers power through dirt and sand. Close on the Caterpillar logo on the front of one of the bulldozers as it pushes dirt over (14:48-17:29). End credits (17:30-17:38).

This is my grandpa in the video he worked for Michigan state land development for 46 yrs he was one of the best operators there was I always heard
That's really awesome. Thank you for sharing that!
Wow!.cool!.
Thanks guys I'm an operator myself and Everytime I get behind the sticks I think of him maybe one day I'll be half the operator he was
@@chrismooremusic4383 Gotta keep that Caterpillar blood in the family!.Love hearing stories like this and I’m glad this film was preserved.✌️😎
He's on the D7?
Man love those old classic cats!👌🥰👍
Well that was intriguing.
Just drove my 1949 D2 yesterday. Still getting the job done.
now that's a real machine, no plastic. if you still have one, keep it in working order
And the heavy equipment operators industry introduced the Roll Over Protection System aka ROPS. And since then and because many other OSHA Heavy Equipment mandates evolved. Thus, Operator lives were saved and injuries prevented. Nothing we do on the job warrants the unnecessary loss of life or limb. Shake hands with danger, human nature, safety and Murphy’s Law comes to mind. USARMY 74-95 Engineer retired. ESSAYONS
This man chewed down four Pall Malls during the recording of the voice over.
And previous to that drank a pot of black coffee, ate a side of bacon , 6 eggs cooked in the bacon grease and then wiped up the pan with numerous cat head biscuits . God bless America!
@Bill Telfer Probably had a flask in his back pocket too
LMFAO
And lived to be a hundred, Never went to a doctor or spent a day in the hospital!
On the weekends he probably downed a case of beer and a fifth of whiskey!
Love that wonderful smell of fresh-turned earth!
...as well as the smell of smoky diesel fumes and hot hydraulic fluid...aaghhh.
Don’t forget the sound of the turbo!😂👍
I was only a kid when I learned how to run the old cable blade D8 and D10. Pony start, pre combustion chamber engines that would lug down so far, you thought they were stalled, but they kept right on pushing. We used them to make logging roads just like in this film. Start at the top of the hill, work down. Push the trees and rocks out of the way.
Don't think U will find a D 10 any where in the world with a cable blade, no such thing.
No such thing as a D10 with “an old cable blade”
The D10 only came out in 1977. Fully hydraulic.
Sounds like you are making up this story. Lol 😂
At the end of WW2 Admiral 'Bull' Halsey credited the BULLDOZER as one of a handful of incredible machines & gadgets that were (directly responsible) for ending & winning The War in the Pacific Theatre...CAN-DO !
3T D-7 one of my favorite old tractors to operate. Big bore, 4 cylinder naturally aspirated engine have a beautiful exhaust note.
At 13 liters they’re not your typical 4-cylinder are they?
We’re still running a 3t on the farm. She’s tired, but she still moves a lot more dirt than the Bobcat will! A family heirloom, so she’ll become rustic yard art once she’s belched her final cloud because it’s highly unlikely I’ll ever part with her!
@@sawsurgeon it's always worth restoring if it runs, drives, and operates.
Ok the D6 and D7 are great ‘Tractors’ in their own right , but the D8 from the 1940’s 8R up through the H series to the modern T series, the D8 is the real legend that’s basically shaped the modern world we know the 👑 of Dozers 🤟🏻
I have an old cable 7. Still runs, it’s a beast. No plastic or electronics
Is it a 17a?
@@graemedalgleish8944 No, it’s a 3T
@@justingarretson2054 I was just curious. I've never run a cable controlled unit. My 7E is all hydraulic.
How is the cable driven? It looks like it may be driven off of the front of the engine, I assume through a clutch.
@@bigredc222 it has 2 cable controls on the back, basically like winches with clutches yes
You use one for the front blade and if you had a pull scraper you use both of the cable controls to run it
When I was a kid in the late 60s, we lived in Ft Walton beach, my dad was flying A1s in SEA, we lived on Cinco Bayou, This was when it was still mostly Magnolia trees and oaks, there was a housing project going in, me n my buddies would go watch the HEO drive his Cat D7, he would wave at us! a big ass bald headed fellow named "Bullet", sometimes he would let us sit in his lap while he was pushing dirt it was just awesome! Now if the guy did it he would probably be arrested. What a time to grow up!
I operated a D8 of this vintage in the early 90s, some injector issues but nothing major,ran great
Diesel cleaners work great in these old machines
I enjoyed this old commercial. I have loved stuff like this, since I was a toddler. I would bet the operator, who pushed the last tree over, would have felt a little better with a good cab over him. I know I would have.
This is back when the men were men and the boys were men too!
I like to say when men were steel and ships were wood.
I’m 75… that said the operators back then would be totally lost with today’s equipment and technology. My father was a “cat skinner’ back then. Alcoholic as were most all men after WWII. And yes worked hard his whole life and died in his 50s from lung and liver cancer and left his large family with nothing. Yes sir the men were men back then for sure.
@@TheMilwaukieDan Those men saw and experienced things during the war that no one should have to endure. God bless them!
@@MilkMan608 I understand. However that type of statement completely discounts any all grief and suffering our men and women have and continue to suffer from in the current wars over the last 30 plus years. Don’t believe me ? Visit a VA hospital or Clinic.
I thoroughly enjoyed this old video. Love seeing the old equipment.
We had a HUGE D7 at Ft Drum to push snow in the motor pool. It would EAT anything! We dumped our contaminated fuel in it...it can run on ANYTHING oil, paint anything...
D7 is Huge!??
Have operated up to D-8 cat with gas poney motor to start the BIG engine!! Love caterpillars!!
Despite all the technology advances today many of the earthmoving methods remain the same . I began on a cable D9 very similar. And because those winches were so touchy you`d soon learn to just dab the lever to keep the cut going smooth. That kept the track from riding over rough bumps . The seats weren`t much more than a kitchen chair and there was no operator protection . I did get sconed a number of times. including concussion knockouts. Not good when your in control of a large dozer. I do remember the pilot start motors too . Glad when the electrics and hydraulics came along .What a different world we`d have today if not for dozers and chainsaws.
I find the hats these operators wear in the video amusing. Good 1930's 40's hollywood villain hats. "Hey Bugsy, take da caterpillar an' cut me a road down to the fishin' hole. I wanna take da boys fishin'." "Sure boss."
Tanks for da laugh 😂 I know what you mean, I turned 58 this year and when I was a little kid I caught the tail end of this fashion for guys. A nice Stetson or Fedora was really prized especially by the working man, almost like having a Lincoln or Cadillac. Well, look at dese crazy broads and dair bullshit Gucci bags now? Da ting is da lids never cost tousands of greenbacks? 😂🤣 even wid da adjustment for inflation? 😁 I remember going up town and seeing all the men with hats, some with suits and some with blue collar clothes. I'd give almost anything to go back to those days now.
@@romangedz730 :: Right behind ya, at 55 I recall pretty much the same headwear in my youth... Thinking about it now, I’d be willing to bet my 87 year old father likely still has both in his closet to this day!🤠
@Michael Fisher:: Crack’n me up with the Bugs n Thugs inspired message!
“So, he’s hide’n in the stove eh? Now if they was hiding in the stove, would I turn on the gas?
Oh, you might rabbit, you might”
Classic cartoon comedy gold👍🏼
It's called a fedora. That's just what people wore.
My father wore a fedora every day. Men wouldn't leave the house without a coat, tie, and hat. We can thank the hippies for changing that, thank god.
If you ever worked with pick shovel and wheel barrel you would really appreciate these beauties. TONKA!
I was there when it was camp drum in the 60's. Yup in the motor pool
well that's going on my Christmas list
You see, a "bulldozer" is not a tractor, it is a _blade attachment_ . No one will accept that these days. But he even says "the first bulldozer _built by the manufacturer of the tractor it is attached to_ ".
I love how having no ROPS is a feature. LOL!!!
Yeah they kept saying that over and over, lack of an A-frame. But felling that tree with the dozer blade...if it's rotten it will fall backwards, right on you.
@@raylopez99 An A-frame isn't ROPS smart guy.
@@lwilton Well I guess you've made the world a better place haven't you. LOL!!!!
@@mytech6779 I doubt it. You don't sound too smart yoursefl. Check Wikipedia. You may be confusing an A-frame on a tractor with what back in the day they called the cab on a dozer. en.wikipedia.org/wiki/Rollover_protection_structure
A-frame is what the winch cables ran on. They stretched from front to back of the tractor obstructing the view of the blade. No A-frame was an improvement for sure. Roll-over protection didn't come factory till much later.
Back when America was normal.
You think no operator protection is normal?
In 1964 learn how to operate at the age of 15, from my uncle. Who was a seabed in Korea. Did alot of seat time for years on a D6 and D7.
Can-Do !
_Alot_ is a town in India. "A lot" is more than one of something.
Its amazing how they did all this work with no roll over protection and no air conditioning , lol !
Worse, they claimed the lack of roll-over protection as a feature, then promised the dozer was stable under all conditions.
Ah, the good old days. When caveat emptor was king.
His air conditioning was a fedora.
No radio either 😁
Heartier stock of people back then. The only snowflakes seen back then were the ones falling from the sky in winter.
thanks.
I used one of those Dozer's to take care of my 2nd Ex Wife. They work extremely well . 😉🇺🇸
this music was used in everything back then from cartoons to horror movies
If these operators would see how well the 2022 dozers are equip they would flip out. With the heater, the A/C, the joystick, etc... :)
Yes, many trees were harmed during the making of this film……..
The pre-hydraulic days. These dozers had dry clutches like a car. They were very operator intensive to operate. Lots of work managing the two track sides and the blade. Worst of all - no covered work space??- What were they thinking? Poor guys in the full sun all day. Todays Air Conditioned cabs are extreme luxuory by comparision.
I still run one,,, so true ,,
Still better than a pick and shovel.
@@JRBUISEXCAVATING
I have a hickory stick backhoe operating license also...
Kept you in shape no Fat operators lean and mean when Americans were tuff now we got the Snow Flakes
They weren’t in the sun all day long. When I was a kid, none of those machines had a ROPS or cabs. What they did have was a bright yellow umbrella on a pole with a 90 degree bend near the top so the operator was in the shade. And of course that yellow umbrella had CAT and/or the local dealer’s name printed on one side in big black letters.
I learned on a D7 E with a hydraulic blade with hydraulic tilt and manual angle. It had a pony motor. And I had an umbrella!
Excellent! Because I can't go to sleep until I've driven my earth-moving equipment!
"Boss of the bulldozer"
Allis Chalmers~ "hold my beer"
I operated a D8 Cat in Canada 1974 with the donkey/pony engine start. The damn thing took the skin off your knuckles due to being too close to the smokestack.
Note the blade is moved by cables and pulleys, not hydraulics, which came later.
And you had to manually turn the link (turnbuckle) one way on one side and the other way on the opposite side to angle the blade
@@flasher1663 that would take a little while to get used to, planning how you'll move the dirt so that you minimize your wasted time
My Dad worked for CAT for over 40 years. WAS a great company.
Nothing like an experienced union heavy equipment operator to get the job done safely, quickly and expertly.
By today's standards it makes this commercial hilarious 🤣
You can always tell an ole equipment operator one of a few ways, they can start and operate anything, they can’t hear a word you said and they don’t ask a lot of questions.
Ease of fingertip operation.
beautiful ❤
That is one trippy sales promo.
More than a few people killed pushing tree over without a canopy.
I cut my teeth on a '52 D8. Pony motor, Cable blade with one rock tooth on the side. That was the trail-blazingest unit ever made. Not the best for close finish work, but point it thru the woods, and you'd have a road in short order.
Love the old cable d6s and d7s got many an hour running them before I got on a hydraulic tractor . Still prefer these old beasts ! Fingertip control my a$$! Get slapped off the machine first thing in the morning. Those old Latunue nylon forcing cone winches would remind you to make sure that it was in neutral on startup! After it whacked hell out of you it usually snapped the 75ft cable! Now that it's running , restring the cable and start working in a fine mood! Lmao! Yeah I have !
I’m sold.
Take my money
Made in USA
Power vs Drudgery @16:20 that was the phrase that pays!
I would like some more information on the truck and trailer used to haul the dozer.
It looked like a letourneau , but I definitely not an expert. Hopefully this gives you a place to start though.
It was a Cat DW-10 scraper tractor. No idea on the trailer.
Maybe a Hyster? Cat dealers sold those back then.
Excellent video - thanks!
Really cool old video thank you
Awesome!
The narrator missed a golden opportunity. He should have mentioned that the blade’s design caused a rolling action while moving dirt. I certainly would have.
lol
Hahahahaha yeah wonder why he never mentioned that??
Squatch needs to see this
I suggested it to him earlier this morning, he acknowledged it.
@@squatch253 glad to know you are here when we’re reminded of you by the past, LOL! 👍
@@squatch253 frick yeah
A magical time before all the pesky regulatory and enviornmental impact issues were a concern...
Yeah; God forbid we do anything carefully.
3:15 no environmental concerns here.
My little D2 has fantasies about being a D6......
Wonder how many soldiers died pushing trees during the construction of the Alaska Highway in 1942? They learned to operate on the job.
Super cool
I love the sound track
Beautiful lines with a sexy plow lol
How surely it goes about its business...
Used to tun a couple of these, very little power but at least they had a closed cab
My dad said that the D-7 was best one to use for you do the work of a D-8 for the cost of a D-6.
Watch a funny film called " Earth worm Tractors" 1930s about this.
Nice
I have a 1956 D7C 17A pretty much restored minus paint
You got any videos of the D2 ag tractors working on a farm
😮 dont 🎞 worry …. I’ll fix it 🤸♂️💥📽 …. 😞…. To those who served in the AV department of my middle school… I apologize for melting the film inside projector #37 in Mrs Fishbacks language arts class…..and the small blaze that ensued was because she insisted it would work itself out instead it piled film into the projector totally surrounding the red hot halogen projector bulb. So I saved everybody’s life that day when I pulled out the plug 🔌… albeit by the cord and not the end … so she yelled at me and said that’s not how you unplug things. But but but…. All Facts !!!
I run a d7 and d8 cat love them
Fingertip controls
That would be fun.
Don't forget to wear your OSHA-approved Fedora when on your Dozer!
In these bulldozer and grader videos, I've often heard the term side draft mentioned. To what does this refer?
Interesting that they never say the name of the manufacturer through the whole movie. Of course it's Caterpillar but they don't say it.
They didn't NEED to say it. The dozer in action says it all.
Caterpillar was the tractor company, this is a sales pitch for the bulldozer, the attachment to the tractor, the blade has its own model and serial number and parts book as well. as did the winch that controlled the blade. Fun to watch , worked on several of that vintage,
At the opening of the film, the first credit says "Caterpillar Tractor Co. Presents". The "Caterpillar" name is easily visible on top of the dozer blade.
@@FAngus-ly8lk Yes, that's true. But the narrator never says the word Caterpillar
@@DK-sw6xx I have relative who is pres of local Antique Cat chapter, it's great to see his Sixty run. My point was the narrator never says the word Caterpillar.
"Powershift trans-what? Never heard of it."
Not until around 1960. First cats were pony motor with a torque converter. To steer u pulled a lever and brake pedal to steer. At idle won't move rev up to go. Not as reliable as late 50s wet clutch standard cats
They removed the overhead protection so they could fit under bridges easier?
No, the A frame mentioned early in the film was the support that lifted the blade before this design. The A frame might have offered some roll over protection in very firm surfaces. Nothing on soft surfaces. The frame would just sink. Protection or not, you weren’t likely to survive a roll over unless you jumped clear. ( unlikely) You would be much like the marble in a spray can.
@@itsthatguy5742 I knew what the A-frame was for, but I figured it had to offer some protection from trees, maybe not big trees but, I figured it was better than nothing.
I think it said that this was the first Cat that the blade and tractor were designed to go together, does that mean that those A-frames were sold by aftermarket companies?
In the days before hydraulics!
Were these bulldozers built at Caterpillar's, long gone, East Peoria assembly works?
Cat.....the one and only dozer
I know where a nearly intact abandoned one of these is. Are these desired by collectors?
we have 1 of these cable operated cat dozers at work....i was trying to guess the year of it....it looks just like this 1....
The 3T series D7 was built from 1944-1955
Cable dozer didn't have down pressure on the blade.
Doesn;t seem to effect the performance much. The blade weighs a few thousand pounds, plenty for most purposes.
@@justforever96 sure...back then. When they started using hydrolics, it changed a lot. Finally the motor graders caught on.
What is the name of the truck in the beginning that is pulling the trailer? Thanks
The earth rolls
Alaskan highway is now open haul road as well get ready for crude oil coming down the mountain through the Alaskan and Canadian pipelines
Hmmm.... no rocks?🤔
D9 1980 ماكينةجبارة
Not one rock in these dozer films.
Roberto were you not paying attention towards the end of the film???
Killdoser movie
Interesting hearing Wagner playing if this came out in 1946. He was eulogized by the nazi's.
He was and still is one of the most important composers of all time. Nobody back then gave a damn what the NAZIs thought.
@@lwilton I teach music at a state university and I have colleagues that refuse to cover Wagner. I appreciate his work myself.
These old ads are corny as hell.
They sound like the propaganda movies at the time. And the training movies, and the commercials.... Hyperbole, patriotism, and manifest destiny.
these puny dozers never encountered the rough land in Oregon. Guaranteed the blades would be dull and their clutches would be burnt up and in need of service 😂😂😂
Oh yeah, I didnt know "fingertip controls" required you to throw in your whole shoulder.
