CAT D6 vs KOMATSU D71

[@bigwig8927]

We need more videos like this then the likes of Cat and Finning wouldn't be able to brainwash the Cat fans in to accepting the same outdated crap with just a new sticker on the hood

[@DAVID-bv2gv]

Well You’re right about that 👍🏻🇬🇧

[@chrisfleming5109]

komatsu in the 90's bought Hanomag and since then have made huge steps forward probably because they can now draw on the hanomag engineering excellence, they had bulldozers running in the 1920's.

[@LordMuck]

I'm a massive fan of CAT dozers and equipment but I also like to show other operators what's currently out there and then it's down to personal preference, running costs etc. You've got to make your own choices at the end of the day.

[@InformedKiwi]

What a great presentation. Objective and to the point. Like it 😊

[@PedroRosas-ue5ey]

❤❤❤❤❤❤❤

[@daveshepherd5352]

It's nice to see someone for a change that obviously appreciates and likes CAT equipment but is experienced and open minded enough to look at other manufacturers. Other channels should take note !

[@numscull12345]

As someone who used to work for Komatsu, those things were pretty amazing to work on. really accessible and really nice in general.

[@not.likely]

Yes, Komatsu is on top of with this one. Operators visibility, significant cabin noise reduction, comfort, power and a bigger blade

[@paulcooper2897]

What I like is that you are comparing apples to apples ... not a 15 yr old clapped out beast to a brand new shiny machine. The visibility in the Komatsu is astounding. How was the headroom? It looked on camera like your head was above the rear window and into the roof? I, personally, would probably enjoy the Komatsu controls. I was never a fan of the thumb lever on the cat for blade control. It doesn't have a "natural" feel to point my thumb straight up like I'm hitchhiking while holding on to the joystick. Thanks for sharing 🇨🇦

[@LordMuck]

I think it was mainly camera angles as I had no problem with headroom with either machine

[@butchpemberton6143]

I am an oldie..72 years old....We had a family owned sand and gravel company in Prescott, Az. from 1969 to 2003...the equipment shows in Las Vegas in late 60s early 70s we would marvel at the Chinese & Japanese there crawling up, in and out of all Caterpillar equipment photographing every conceivable inch..We owned Cat, Komatsu & Terex loaders, dozers, haul truck,backhoes...And Komatsu are great machines however, the used value market price was not the best and we did for the last 15 own primarily Cat. and had buy back program with them. Enjoyed your video..Thank YOU.

[@LordMuck]

Thank you for sharing 👍

[@donstewart2872]

I also have to give the D71 cab top marks. Theres actually room for your lunch kit and your thermos doesn’t end up under the seat Comfort, huge improvement in visibility and extremely quiet. Even when you are walking past the Komatsu as it’s working, it’s extremely quiet.

[@-2u2]

We purchased a ranch this year and need to develop roads to access some of the more remote locations. I was considering the D6, but after a day of demoing, I hated the visibility and just could not warm up to it. We have a D71 coming out for a demo next week. I'm really excited, especially after watching this video. Thanks for your non-biased content.

[@craigross8777]

As a heavy diesel mechanic I've spent a lot of time in the forestry, on civil construction sites, various mine sites etc then i worked for a heavy hire company which had a large fleet which included Cat D4 - D11 and Komatsu D41 - D375 dozers. We found the Komatsu's to be more popular with our customers due to its pushing power and low centre of gravity. Both brands are good, but the komatsu's reliability and performance is second to none and I would highly recommend. As a mechanic the only thing I would say about dozers in general is they can be hard on the body and very difficult to work on with poor access to the transmission etc often having to remove very heavy seats or even whole cabs to gain access and a lot of the Komatsu models being Japanese were no exception, luckily with some of the later machines now you are able to tilt the cabs for access, a feature that john deere and liebherr adopted a long time ago. HST models are certainly becoming more efficient, reliable and popular. One thing to consider with dozers it is very important to look after and regularly service the rear end, final drives, bull gears etc as they are naturally prone to wear and failure. Really enjoying the content and commentary, keep up the good work mucker, cheers

[@Randyman4126]

Hey Craig,have you experienced any steering issues developing around the 16,000 hr mark on Komatsu?? I have not personally experienced that yet myself..That's what I have been told by numerous techs/mechanics..Also that it can be a bit of a nightmare to troubleshoot..I do prefer Komatsu tractors,so this is not a negative comment,rather a legit question..

[@craigross8777]

@@Randyman4126 Hi Randy, I haven't personally dealt with any steering issue's on the komatsus the hire company i worked for didn't usually do quite that amount of hours before they would on sell them. I do recall some years ago one of the other techs I used to work with having some issues with the transmission and steering on an old D155A-3 which had quite a unique setup withs lots electronics. From memory it needed a new wiring loom as it was plagued with too many intermittent issues. Cheers

[@jonnywhitelaw8224]

The company I work for has a lot of Komatsu machines and we actually purchased the first D71 that was sold in the US. We have all Komatsu dozers and backhoes so I’ve actually never ran any CAT units. But after seeing this I’m happy we only have Komatsu!

[@LordMuck]

CAT are fantastic machines, we ran them for years. The D71 however is just better but CAT will get something to counter it and so it goes on.

[@charleswooters]

I'm not an operator, but I'm a transportation worker, and I absolutely love the Komatsu they easier to load on a trailer greater view and they have a more precision handling. From my mechanic friends I hear they cheaper to work on and not a engineered nightmare. They do tell me that getting cat parts are easier.

[@Flatlander11]

Ran a Komatsu 71 in steep mountain terrain, absolutely loved it!

[@carltonholmes8061]

I am on a Komatsu D65 at the moment and I am impressed with it, even after operating CAT D6T’s. Look forward to operating the D71 Sooner or later.

[@adamhensel4877]

We have CAT and Komatsu at work. As a mech’s point of view dealer support is critical! They both break and getting parts or tech support to get them back up should be considered as well.

[@pyroplim6967]

I started out on a D4 hand clutcher or the signal box as i called it due to the amount of levers.Then a cold winter on a D8 with a live chicken nesting in it no joke.Then farm contracting for years then a few yrs at a quarry on a Komatsu wa 470 shovel and a D6 C. The yrs rolled on and i went backwards ending up on a 41p Komatsu dozer or the dreaded 41 hand clutcher as know one wanted or said they could drive it.The worst dozer i have operated was a D6 R on narrow tracks the best was a D6 H with the tiller steer on wide tracks.We call dozers under the D6 size worm disturbers up this way. Great vid LM as per.

Appreciate the info from someone with the skill of an experienced operator 👍

[@dozerblade]

I'm retired from all this now for seven years, so it was nice to see how things are improving , I'd love to have go in the Komatsu.

I'm sure you'd enjoy it. The exciting bit is to see what Cat come out with to regain the ground

[@quinnhenshaw7293]

D61 is phenomenal as well. We have low ground pressure and standard and I love them. Auto control is on point esp. awesome for sub-grading gravel for long roads. Komatsu makes my favorite dozers. Even the 51 has loads of power. I’m glad this guy is pulling for Komatsu

My company bought a 71 recently been running it for awhile now and it is a very well balance dozer and it will roll the hell outta some dirt I’d run it over a 6 any day

[@rossgray3070]

Did a few days in a D 71 PXI a few mths ago and thought it was an awesome machine, loved the visibility and the hydrostatic drive, and room in the cab. I usually operate a D 7R2 LGP but have spent of time on everything from D 10T to D3, TD 6 to TD 30, but the D 71 would probably be the No 1 machine for me for doing what we mainly do which is residential subdivisions here in QLD. Been on dozers since I was 16 and 73 now so have a wee bit of experience on them.

[@patgreenerides]

With 40+ years operating dozers of all makes and sizes, the majority of that being on the mighty Cat i feel well qualified to give an Operators opinion on the Komatsu D71 Pxi.. Tru plant had the first two in the country and my backside landed in the second, it was comfortable, quite, powerful and dripping in useful tech.. I was really Impressed on so many levels.. If I was in the market for a dozer of this size the D71 would be my choice followed by the new Liebherr ..

[@LordMuck]

Appreciate the insight 😉👍

[@douglasmayherjr.5733]

Pretty impressive comparison between the Komatsu and Cat. Cat is hard to beat but I think Komatsu has got them out engineered for the moment. There are people that will only ever run cat, they are missing something pretty nice. It would be interesting to see how they hold up over the years. Thanks for the video.

[@neilcotten2816]

Good video, I think some brands take it for granted sometimes that they’re good and don’t put as much effort into keeping ahead of the competition. That cab on the komatsu looks a nice place to spend a long shift in with a great view of the surroundings

[@tripod6406]

Cracking video Muck, really impressed with that Komatsu, wouldn't mind driving that.

[@dozerboy67]

I have run a lot of Cats and I’m a die hard patriot but, I also appreciate a good thing when I see it. I have noticed that there is better visibility and room as well as acoustics, they’re just not as loud, the Japanese engineers have been hard at work and have produced a fine machine! I still have a lot of pride in caterpillar, even though they aren’t altogether made here in the states anymore. I would like to run a 475, I have run all the dozers except the D11 but I hear that 475 is a beast!

[@NickJones-n5y]

Every time I get out of my cat and run one of the deer’s and want to turn I pull it out of gear 30 or 40 times.Every dozer should be push button forward and reverse. That’s probably my favorite cab improvement from Cat.

[@conmanumber1]

In last 25 years theres a few Cat owners who gone straight to Komatsu and Hitachi as operators love the operate by wire controls and comfort. Komatsu had always had a long relationship with Cummins engine Co wether using American or Japanese made Cummins engines. I believe this is Japanese.

I worked for both cat and Komatsu each close to a decade. As for dozers. Hear me out. The Komatsu rarely have trans failures. But pretty tight for any repairs. The cat is just so much easier to repair.

[@davidstaddon5932]

Great Vid Kurt I have recently been on a job that had a new Komatsu D61px and a new Cat D5 so like for like in spec. both running on leica Gps for final trimming . My own opinion at the time was the Komatsu would out push the Cat and use less diesel . The Cat on the other hand would be faster at trimming . Even with the poorer vision it seemed to function better with the identical gps system .Myself and the other op were in agreement about this . Out of choice i would operate the komatsu . Keep up the good work and you will really enjoy using a tilty. There is a guy near me who has a tilty on a 4cx ,absolutely amazing piece of kit as he can drive, steer and change direction through the sticks as well as operating the backhoe and tilty.

I was a die hard Cat guy until I had the opportunity to operate the Komatsu D51 and D155, the visibility was second to none and that D155 was a beast, both were very smooth to operate and comfortable for the operator. I still like the Cats but I'm leaning more towards the Komatsu now. I'm really liking their excavators now as well. I was also impressed with the visibility on the 1650 Case dozer as well, it's pretty close to the Komatsu.

[@Woolzy603]

Ive been running a new Cat D4 for a year now and before i got it i did try out a PXi51. I totally agree Komatsu has it for cab space and sound. I also noticed on the inside was that a majority of everything was steel not plastic like Cat. But i think Cat has the comfort over Komatsu. Thats one reason why i picked the Cat. They also changed the hood so you can see better looking forward. But Komatsu definitely has the visibility in my eyes. I also liked how where the cab is located didnt think you got beat up as bad. Awesome video!!

[@jacobdavis1752]

That D6 N is on a 5 H frame . Cat has gone from numbers to letters being the R and T are substantially bigger. We ran the Komatsu 61 exp starting in early 2000s and I was sold. The moldboard will tilt drastically further than the cat. I’m not a fan of high tracks but we have had with them for years. Over the years the Komatsu has held up with less services required. I still prefer a cat motor grader over the Komatsu. Cat has Mitsubishi power 😮sad. I feel Komatsu both in excavators and dozers durability , service, comfort, and power winner. I agree 100% on the controls. They have been clunky and strange since going from linkage. Thank you for the content.

Probably fair comment on the smaller dozers , different story when you get into the 8 to 11 size dozers. Suspended undercarriage high track every day for me , operator comfort and productivity on the blade are pretty good on the cats , the big kommagutsas can rip though, and wreck your back!

It’s bs. John Deere does the same thing. Don’t believe me? Go on machine trader, pull up cat, then start looking thru the models, they’ll have a tag that shows where it’s made.

Been running equipment for about 23 yrs I’ve worked on farms, logging, civil and for the past 7yrs I’ve been matting and environmental engineering for utility companies. 4yrs ago my company bought Kamatsu excavator which I was immediately impressed with it will out lift out dig and out perform the cats n Deere excavators we have all day long and for being zero turn it is unbelievably sure footed. It will pick up 4 12”x16’x4’ timber mats weighing around 3300 lbs each and swing around fully stung out n not even begin to lift up which is pretty good for a 40,000lb machine the cats n hitachi machines of equal size wont handle half that load and stay planted and they are mostly normal configuration not zero turn machines.

Reading the comments the Komatsu is ahead of th Cat where it counts and that is in the work rate, if the fuel costs are lower too then Cat are going to have to work hard with their next generation of machines to catch up and maybe steal a few ideas to improve that bloody awful frontal and rear visibility. Having the operator constantly craning their neck to one side to avoid that blind spot on their left is an atrocious piece of design work, how that one got past the final prototype stage is a mystery. The only thing I wonder on is the hydraulic fluid, how tolerant that is going to be to prolonged heat and will the service schedule need to be as rigorously adhered too as much as possible to prevent the fluid from breaking down? Other than that I would say on terms of operator comfort and the ability to use the dozer in the most efficient manner the Komatsu is way ahead and as you said it is a game changer.

[@roberthuron9160]

The irony of the Cat/Komatsu is that Cat used rear radiators,on the 973'sTraxcavators,and that was adapted off of D6/7's! Mayhaps,Cat might look at some old blueprints! Any good inventor looks at other plans,to see who has invented the better mousetrap! And KZbin has a series on just that,some real light-years in advancements!

I spent 40+ years operating equipment. Caterpillar went from the pinnacle of equipment to overpriced junk. I would like to see a comparison with either Cat or Komatsu vs the Dressta TD16N. Interesting dozer.

[@geedubb-q1u]

Cummins in Komatsu, and Mitsubishi in a CAT? Interesting. For golf course shapers the Komatsu would be a great option, mainly because of the view.

[@alovero2]

Cummins and Komatsu have a Joint Venture called "IPA" where they manufacture engine blocks together. The D61 has an engine that is basically a 6.7 cummins block with a komatsu rotating assembly and cylinder head and Denso fuel system instead of Bosch. The 6D107 engine (6 cyl, 107mm bore). In the case of the D71, it gets the 9 liter engine out of the D65 (6D114 Engine). I've always heard that is actually a full Komatsu engine; 540 cubic inches (8.9L) but I dunno it looks pretty similar to a cummins L9. Even though the L9 is supposedly 543 ci (9.0L) displacement.

[@alovero2]

One more thing; komatsu does use a holset variable geometry turbo like a cummins. However the komatsu VGT is hydraulically actuated and the cummins version is electrically actuated. Also the aftertreatment system on the Komatsu is different. Would be interesting to compare the bore diameter and spacing of an L9 vs. 6D114. Quite possible that the block is the same but I dont know.

[@AircreteHarry]

I work at a landfill that accepts industrial waste from drilling rigs. Im courious how the flotation is in mud.Belly pan dragging, stuck kind of mud.

[@LordMuck]

[@rodleypumpkins4174]

Hard choice for sure Cat has more models and motor options Down to specialty models. I’m an operator by trade and I’d prefer a cat I think they run better with less issues. Cat has the emissions figured out better. I’ve been in 3 different Komatsu dozers doing dozer things and because the DEF wasn’t topped off and each time below quarter tank they suck air bubbles and put it in limp mode and a tech has to come clear the code. Never has happened to me in a cat. Sometimes if it’s real cold the komatsus and Volvo equipment throw codes and sometimes limp mode because the def sensors are too cold. If I was buying a dozer I’d pick komatsu because the gps stuff is built in and ready. Cat you need to the domes and screen still.

Just found you on KZbin. Like the videos and just spent a weekend binge watching. I remember when I was a kid in the 80s. I was fortunate enough to go to work with my dad, Grandad, and uncle on the same site, digging some duck ponds. My dad was on a Cat D8f with manual transmission and donkey start. My uncle was on a D6, and my grandad was on a Komatsu D65. Everyone had a go on the newcomer (Komatsu). All wanted to hate it, but all ended up respecting it. It wasn't long after that all the Hymac back actor's went and was replaced with Komatsu.

Vision is key now, I work n earthworks on infrastructure projects and for some strange reason people love approaching big and yellow bits of kit. Great vid as always
