The Top Largest Bulldozers in the World 

@@karlc8808 Berry cool is what we’re after!

hi S B... ' america made caterpillar D11... japan made komastsu D575A

Make them fight!

the d11's are perfect in size and they can handle just about everything. the biggest komatsus are too big, they cost too much to operate. and the smaller ones... well they are not on par with d11's.

The 575 Komatsu is only a special order machine there are probablely equal numbers of 10s and 11s vs komatsu. There are quite of lot of leibherrs bid dozerwith the hydrostatic drive.

The stoped making the Komatsu Dozers because they are so hard to transport. At least that’s what I was told and they only run on big mines or other big jobs where there’s nothing they can run over and crush. They are the baddest Bull Dozers on the earth, and yes the newest Cat D-11 is another bad ass dozer and it does the job it’s put to but they do have a tendency to run hotter than they should. But I loved it when I got the chance to play around with it for a week I’d buy one if I had the money and a place to put it.!!!!

Knowledge.

Well it did work one job ,but after that it was decommissioned due to Gaddafi's links to terrorism. When the United States impose trade embargo it just sat around unused as it could not be exported to Libya, also the high cost of Transportation didn't help with exportation. It weighed 183 tons and had 2-675 horsepower caterpillar engines which brought a total of 1,350 horsepower. Built mainly of all caterpillar components. It's practically just a Giant caterpillar bulldozer on steroids.

Like the virgin Mary

Over 2000 ft lb easy

@@cdub015 you mean lb ft.

And it never saw one day of construction or use......... It was a joke

You are absolutely correct: 10hp/ton is the magic number and exceeding it creates enormous stress on tracks but in particular the transmission. In this the CAT is still the best but even this beast needs much needed maintaining even if less to it's competitors...

Paolo Viti I used to haul locomotives, (Brookville) and they also use the same formula. They we're a direct drive via roller chains, and used sleeves on a shaft to regulate the guage, and could also offset the machine left or right on the tracks for visibility by changing the sleeve arrangements. I suggested using the John Deere axle method of slotting one side of the axle and using a worm gear to move the wheels to desired guage and position, worked great.

@@Colt-tf6xf that is very interesting as I know almost next to nothing about this aspect. My experience is really limited to tanks as I was driving a Leopard 1A2 in 1976 during my compulsory military service in Italy that I really enjoyed myself but in the same time it was a formidable technical experience!!

Paolo Viti the common reply would be thanks for your service, but somehow it doesn't quite gel in Americanspeak, but certainly salutation for your call to duty. I have ran quite a few dozers but never got to be around tanks. Sometimes, when the going gets a little tough and the tracks are slipping in the mud, I can hear the Deutsche battle songs in my head from a previous life in the SS Panzer division. Can't explain it.

@@Colt-tf6xf lol, but I garantee you I had much fun. A curious thing for you: in the warehouses there was mountains of tinned meat and whatever still from the war and I had to eat it but it wasn't so bad and was packed with German and American guns of all kinds. Wow...

1150hp in 150ton machine is low af Its the torgue and why tf is that not shown there

hi M M... ' who is a word - THEY -

@@bestamerica What a stupid question they as in a figure of speech you no the subject we are talking about . You just want to be asshole

@@mitchellmullins9411 hi M M... ' dont use a word - YOU - on me... dont insult me bad foul words... let explain about a word - THEY -... they is a only -- people -- and not machine vehicles... how smart is that

Two wheel drives to move the same track?

Michael Tarasenkoop it would make no difference, it would actually hurt it because you’re distributing torque and hp again through another whole drive to move the same track

It's kind weird they rate it in horsepower rather than torque. But that is how they're rated. Both bulldozers and tractors in general. All these engines rev about the same (HP = torque * revs), so it gives you the same idea. And comparing between different dozers it'll be relatively the same.

@Austin T. they put on a rail trailer or pulled with a jeep outfit under the rear wheels .....front end loaders are also transported by rail trailer on the road I used to do off road tire work and cant count the times I've sat on my ass waiting for the loader or pan scraper get to a quarry or job site then wait on the tires and wheels to get there so I can plan on working into the night and after mid night to get them mounted ....got paid for my time and was on the clock until I pulled my tired wire out ass up in my driveway it was good money but it was tiresome work waiting for everything to show up ......once was on the clock from 7 am that morning until 4:30 am when I got home took a shower got about 3 hrs of sleep then to another jobsite to do another one which was a scraper it was easy all I had to do was mount the tires then help unloaded it from the trailer and use my boom to fold the tag axle up on the trailer .....

Boss has four of them we tore him down all over the country took them different places 1 we tore apart in Alabama took it to Carbondale PA the blade itself is a full load 80000 you take the tracks off you take the side rails off take the cab off you take the Ripper off so you got to put it all back together

It never moved. Piece of junk. Ill take my d -11 all day long

How*, not hot 🤪
