KOMATSU D575A DOZER RIPPING

[@MichaelPowell-w5j]

That's a freaking beast. Great access and amazing video. Thanks

[@signal44]

Not bad for a machine with just shy of 90000 cabiliion hours on it ...sweet ... tracks nicely polished and rounded off .... a worker for sure

[@justforever96]

Funny, it doesn't really look very big without anything to compare it to in the shot. It looks just like any old dozer until you notice the size of the operator in the cab, and the railings around the cab area. Also, what sort of engine they use in these beasts? Doesn't sound like an inline-six, sounds more like a V-8 or even V-12. Sounds great. And that stack....jesus!

[@justforever96]

I was right...V-12 turbodiesel. Makes sense....just two big inline six diesels with a common crankshaft. Inline six is the best choice for a diesel; the only inherently balanced engine out there except the V12, which is just two I-6's really. Less vibration means longer life for all components, and the configuration gives a good, long stroke for more low-RPM torque combined with even power production and less friction due to fewer cylinders and valvetrain components. But with an engine this big, you really need more than six cylinders or the RPM will be too low. Thus, you use two I-6's and make a V-12, which gives reasonably RPM (and thus horsepower) and cylinders small enough to be efficient and easy to get to operating temperature, along with smooth operation.

[@MichaelPowell-w5j]

1150 HP V12.

[@bcmcustoms1]

my god!!!! ive only seen the super dozer once in person, i have to say biggest dozer ill evr see in my lifetime!!! i saw it in a equipent show, reel big one in connetcutt

[@mrbluenun]

Hi SoCalEarthMovers, Rather tasty paint job on this dozer! I see now it matches your channel. Dur john wake up boy! There I gave myself a good talking to. Thanks for the upload Take care. mrbluenun

[@Kurdt1]

Got to love that piece of steel.

[@نادرخدادادی-ف3ن]

چه بلدوزر کوماتسو وچه کاترپیلارهرجفت عالی هستند حالا بگویید من چکارکنم بتونم یک دستگاه بلدوزر خریداری کنم

[@Only-one-life-68]

Love yo operate one of these for a week. There most likely isn’t many left in service. Though it would be great to hear that someone knows we’re one is still working in the world

[@generationll]

Where did you find this?Is this is Southern California or somewhere near las Vegas?Would love to see one.Walter Bennet of BennetVideos has on KZbin has put it least 2 o D575s up.Ironically the 1,050hp 316,000 pound D575 was introduced 20 years ago in 1991

[@dali366]

The Acco super dozer is a solid piece of heavy machinery. Built with Cat parts and by an Italian engineering genius. The Acco would have a greater tractive effort than the D575A.

[@mikldude9376]

awesome to watch big machinery in action, how long is that ripper ??

[@aandrave]

The blades on these are 16 feet tall, which makes the ripper appear to be in the twelve foot range. The scale of these machines is hard to grasp with nothing next to them.

[@mikldude9376]

Garbil Huler wow , amazing bit of gear , thanks for the reply mate. cheers.

[@mfad-pz3uk]

awesome sound!!!!

[@ОлегХарченко-ъ4з]

блин, вот это зверюга!

[@generationll]

Where is this working?

[@Kaegis]

So what is the ripping all about? Does it soften the earth to bulldoze it afterwards or is it to prepare for another machine to come in?

[@deksper]

Either option

[@movilmixs]

after the dozer finished ripping the ground do you put the excavators to load the material that has been soften? and why put just using exavators to do the work?

[@Only-one-life-68]

Most likely a mining excavator with a shovel loading highway trucks. Scrapers possibly but I wouldn’t bet on them..

[@bborkzilla]

Now that's what 1000+ HP should sound like.

[@AZ_Iron]

This is a great video, how big is this compared to a D10 or a D11?

[@dhewitt2514]

bigger than a D11

[@56pw]

Hey socal, If I mail you a rag could you run out & clean off the D575 decal? LOL. Seriously is this the one outside of las vegas?

[@dali366]

The Acco dozer is larger than a D575A.

[@jamzales]

common sense. The ripper breaks up hard ground so it can be moved with dozer scraper and or scooped with an excavator. In the Klondike in Alaska/Canada you need to rip the ground known as permafrost. Boy if parker Schnabel had one of these he could do some damage at his site. Of course this piece of machinery probably cost a pretty penny.

[@jimmyjohnson7769]

Jeff Meyers that and the fact that they sink alot

[@jamzales]

Wasn't it a575 Todd Hoffman got for Dave Turin on gold rush

[@jimmyjohnson7769]

nope 475

[@jimmyjohnson7769]

the 475 comes in a super dozer config with a larger blade

[@garethifan1034]

Now THAT's a Dozer.

[@LasPlumasRangers]

@casecx700 The D575 is larger than a D11.

[@silverscrew]

this is the Bentley of earth moving equipment

[@gangesexcavating]

@alco424 LOL, that was a good smartass comment, I laughed. We have a bunch of Komatsu equipment at work. Seems the local SMS dealer has treated us okay but your point is well-echoed out there. Anyway, my personal experience with Komatus is it is good well made equipment thats always harder on fuel than the competitors, But thats my limited experience in their dozers, and excavators. Anyway have a good day.

[@Eric205gen]

the only thing that comes in my mind when I see something so powerful is cost of oil..

[@mikepowell1076]

That ripper has to be close to 8 feet long. Very impressive

[@jserra17]

@gianlucaf9 Go to their websites: Cat's Biggest, D-11T 850 HP, 229,850 pounds. Komatsu d575A 1150 HP, 336,000 pounds.

[@Jack_Rabbit71]

Gotta love that SAD12-170

[@danielmarshall4587]

oh yes please THAT engine sound.

[@allistairc123]

great video, but its speeded up a little?

[@chechnya]

I'd be willing to bet this piece of machinery cost into the millions.

[@1693caterpillar]

Don't know why they don't manufacture a three shank ripper, or don't have one in place on that machine? Looking at the highwall it lookes like it's hardpan. One more shank won't stall that machine.

[@RyanVier]

an 11 is almost half of a 575, a 425 i think is comparable to an 11

[@Farmergreen877]

Size isn’t everything tho a d11 can easily push more dirt in a day than even a 475 but a 475 can rip better than anything else

[@swampratt36]

Helluva machine but I just don't care for the ergonomics on a slope or visibility . Thanks for the vid .

[@guillermoleiton.6100]

Yo trabajé un bulldozer komatsu 355 en la carretera San José Limón una delicia de bulldozer de 4 marchas algo potente tanto que superior al Caterpillar d9 Saludos a mis compañeros aquí en Costa Rica de maquinaria pesada Memo leiton de San Ramón

[@ianzainudin4045]

new trasformer movie trailer?

[@mrbluenun]

@jserra17 Nice to see someone giving some idea of the size we are talking about, thanks. Take care mrbluenun

[@Hongtairang]

Still its won't have the push powers as much D575A and just look at Acco track mover size and its location. Its just taller than Komatsu and that all.

[@gianlucaf9]

@jserra17 you're right.sorry

[@dali366]

The Acco would push a Komatsu backwards with the Komatsu tracking 4wards! ;)

[@GFWoodchuck]

One ripper is all you need. If the hard pan is truly hard it'll break apart just fine. If it doesn't with the one it really isn't that hard anyway. Two or three shanks are just a waste of fuel and time.

[@LasPlumasRangers]

You don't say! The Acco dozer is the largest dozer ever built, so how could it be bigger than a D575?! ^^ But now that was not the subject of the discussion.

[@adisonbenigno1388]

GOSTARIA DE VER PESSOALMENTE UMA MAQUINA DESSA DE PERTO.

[@Gavin84w]

So if Cats are shit can you please explain to me why the way more expensive D11T sells at a rate of 3 to 1 for every Komatsu D475 sold, honestly why would you pay more money for a turd?

[@heavyequipmentman100]

more vids of this please!!!

[@steininge96]

@gianlucaf9 too bad for you cat make big dozers but not the bigest

[@LasPlumasRangers]

@gianlucaf9 LOL "jserra17" as already given you proof. A Komatsu D475 is even bigger than a D11. Not much but still.

[@mehmetdanacoglu5305]

Video yaygın olarak çıkmış

[@gazof-the-north1980]

The dislikes on this video must have been from Moles?

[@rodneymcgiveron]

still rather have a Cat D 11 ...The 575 is no longer made either...

[@The_blindpizzaguy1300]

That bulldozer maybe bigger than the cat but I think the cat actually sounds better however if I were to see one of those bulldozers ripping somewhere for real I would be pretty happy

[@yaomingdixshanghai6125]

This bullder make biggest cat bulldozer D-11 look like a little bitch! lol...

[@harleydavidson8380]

There's a reason why most mines use cat dozers over shitatsu

[@dali366]

As soon as the grousers wear down on a D575A it's a sitting duck! Don't get me wrong chief, the D575A is beautiful machine for landscaping but an Acco is the King ;)

[@mrbluenun]

@alco424 Hi, Why all the anger, who has rubbed you up the wrong way? You have the same kind of videos, and have actually uploaded three, so if you do not like this site go somewhere else? You have to admit this channel's videos are pretty good. especially the latest detailed ones. Hope you are happier soon. Take care mrbluenun

[@alco424]

@13frontrow Why the hostility? Kind of uncalled for, don't you think? And can you show me where I said I've never seen a Cat break down?

[@djspecialpaul]

nice nice

[@heettreet]

time to blast ,, save time

[@epj900]

It always puzzles me watching your videos,- what on earth are all these huge earthmoving projects taking place, I thought California was bankrupt!! Are they just make-work jobs? Are they for new highways?

[@dirtworks7511]

Usually private developments.

[@JamesSmith-qn1wj]

thats the biggest dozer in the world cat doeent even come clos to it in power or weight that has a 90 yard blade on it thats capple of pushing 90 yards of dirt at one time thats almost 4 semis full of dirt

[@gianlucaf9]

@LasPlumasRangers I don't believe that!

[@Paddywhack1976]

i drive a d10 but this is an absolute monster compared to my cat.wow

[@alco424]

How 'bout that, 6 minutes and 47 seconds....and not a single breakdown....that's gotta be some sort of record for Big K!

[@DFRDRIFTPIG]

it maybe the biggest dozzer in the world. but it looks horrible in my books. at least the Cat dozzers look mean.

[@manuelafonso341]

isto sim é uma máquina não é como o brinquedo que eu ando assim dá gozo e mostrar trabalho um abraço

[@RAYMOND1388]

recontra mas

[@dali366]

Ha Acco is a vintage dozer built by wise engineers.

[@ЛеонидЗахарушкин]

Заебись

[@abodakl10]

🇸🇦… 😅👍… GOOD

[@yaomingdixshanghai6125]

Cat shit! can't push. Cat just like Chevrolette and Komatsu is like Toyota or Nissan, look better and last longer.

[@JimBruce42]

@casecx700 much bigger

[@catskinner7564]

You talking apples and oranges cx-700 is an excavator not a dozer does a cx700 way approximately 336,000 lb

[@alco424]

@mrbluenun Exactly what anger would you be talking about? I made a joke about Komatsu's typically poor service availability and had someone who obviously is angry call me an idiot for no reason. I haven't been rubbed the wrong way, and like this channel just fine, so why would I go anywhere else? I'm perfectly happy now, so I have to tell you, I have no idea what you're talking about.

[@CATdozerboy12]

Typical komatsu... leaking

[@Hongtairang]

I don't think so man D575A is still the king and its will makes the Acco look like a bitch! just like all the Cat.

[@Paddywhack1976]

clown

[@MrLostkiwi007]

Komatsu can rip n push but put them in a hard rock eviroment n the cats win hands down

[@jasonjohn2657]

Stewart Aitken nah L buddy

[@jw4620]

1,150 HP and one spike? That's like Ford's one wheel burnout video - NOT impressive!

[@cristiandemirel1918]

If it had two spikes, it would rip through the space-time fabric!

[@Hongtairang]

Acco is joke! using cat engine and its cat but nothing els. Its just taller look mean but don't let's the look fool you.
