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videos like this then the likes of Cat and Finning wouldn't be able to brainwash the Cat fans in to accepting the same outdated crap with just a new sticker on the hood

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 !

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

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 🇨🇦

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

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.

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.

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.

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

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.

Great video Kurt and camera work 👌 enjoyed the view seeing from the operators seat and as shown in the video the all round vision on the Komatsu was brilliant 👍

Great video. Enjoyed watching 👍🏼

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.

Thanks for the review. Was pricing out a Deere 850L , Komatsu 71 and waiting on Cat's D6 price. Keep up the good video content

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.

Interesting video as always. Thanks for showing us. 👍

Thanks mucka I’ve always been interested in dozers great insight into their operation and a fantastic video. Your production skills with these videos never ceases to amaze fantastic well done and thanks for taking the time to set it all up and share with us

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

Great video mucker some great bits of kit and excellent filming 👌🏻👍🏻

Really good set up video showing the differences between the two machines, the komatsu does sound a lot more quiet and loads of vision. Great camera shots M'lod 👌 Keep it up! Cheers, Mike

I know nothing about dozers but this review video in golden! Proper amount of explanation and fluently to the next topic! Well done Sir!

Love the front end design on the Komatsu, it gave me an ease when operating that I would have never known until operating it myself and not using any extras just running it as manually as possible it is so smooth.

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.

Great video and a nice insight into both machines. Like you say for CAT to catch up now - modern technology and advancements would be interesting to see what they do next. Like the idea of the rads at the back.

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

Great video and love the comparisons

Great information, Thanks!

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.

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

I love to watch the D11,this machine really amazes me and the power it has, learning what you say of the view you have of the Komatsu make's sence to me, thanks for your wisdom onto this 👍

Excellent video Kurt ! Very interesting to see the new tech ! And good to see an unbiased operators review of machines ! It does seam CAT stick to some older school designs and tech but just make it look or sound more modern ! Keep up the good work !!

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

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.

I have run both of these, I really enjoy them both.

The off set intake and exhaust pipes are also really nice on the d71 it's such a simple design chance but it opens the front view up massively

Cool I just love these kind of videos thanks Mucker 👊👍

Great footage on those working side by side👌 cheers

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.

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 ..

I run a John Deere 850 with 10,000 hours. Super productive machine.

Some pretty snazzy shots and editing going on here. Very impressive.

Great video Mucker, well presented as always. Well done, that looks a handsome beast.

Superb video pal 👌thanks

Definitely worth the wait mucker 👌🏻 brilliant comparison

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.

Great job with this video. Greetings from Asunción Paraguay 👏

My company has all cat dozers and one komatsu, if you want the d61 you gotta show up early

Great review and comparison Kurt💯👌👍🙏😎

There do seem to be alot more of Komatsu dozers appearing around the countryside on job sites,

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

Good old video that monsieur muck, I don't get enough time to be qualified on judging dozers, but your video is very informative!

Good detail Muckers, great vid

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!!

Great Video 👍👍👍 I'm A Field Service Heavy Equipment Mechanic For A Very Very Large Rental Company In The USA, before our buyout we where strictly cat Now where Komatsu,John deere,& The infamous HITACHI FROM Baby excavators to EX1200 & We have just recently bought some D61 & 71 All good here Keep up good Video 👍👍👍👍👍👍

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!

I run a d61 everyday and once in awhile a 51 on the same platfoarm as this beauty working with a sewer and earthworks company. Amazing machine and leading edge visibility its hard to go back to the competition.

Both look very capable machines I think if I was in the market for one I'd probably go Komatsu👍🔧

Nice video. Spent many years in both myself. Komatsu all the way. Tall men like myself appreciate that large area and better visibility. Keep pushing!!!

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

Enjoyed your review. If I'm ever in the market for a dozer ...

GREAT comparison! A few minor differences however that 71 really has the guts and visibility! Thank you!

Brilliant video again , worth the wait 👌

I've operated caterpillar dozers for many years and would say they are the best, but i operated a komatsu D61 a few years back and had it for 18 months trimming and pushing bulk materials and i was very impressed , comparing it to the cat D6N there both equally as good, I've not had the pleasure of operating the D71 yet but im guessing its a beast! Good vid mukka 👍🏻

Great review of the Komastu , matching it with the Cat . You have better cab vision and control's . Well done Mucker 👍 🔧 🚜

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.

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!

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. Currently using a D6t but would love to try a new Komatsu to see how they compare. One advantage the cat has is the ability to clean the tracks easily with the high drive.

Been on a 71 for the last few weeks, love the thing, great vison, what a step up in design. Also I think my manger has talked to the boss to go buy a 81. Fingers crossed.

The difference in vision inside the cabs is astounding. I think you nailed it, that Cat will have to step up their game. Both are nice machines but I can see the benefits of the Komatsu.

Just found you on KZfaq. 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.

I borrowed a friends Kamatsu to dig a pond it was a beast.

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. I’m not one to play favorites I love all equipment but it’s hard to overlook the performance

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!

I’m sitting in my D65 on my lunch break right now and I love it, I’ve had D61’s and PR726 and 736’s but never liked the hydrostatic. I had a D6R Then a D6T for 4 years and really liked that. I’ve had this 2014 65PX for 4 years now and I’m in no rush to move to Hydrostatic again. Nice video dude I haven’t seen any of your stuff for a while I’ll have to keep my eyes peeled for more 😂

Komatsu are far better. Here in Aus the boys love them, but cat is often cheaper due to the US owning Australia. Been eyeing off the D71PX/i for a while, would be my choice. Thanks for the Video mate.

Very interesting video Mucker and eye opening because cat have been in front for years with dozers but the new one one has pushed it to the next level. Great work fenland Rob

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.

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.

I have put many hours on D61PX and think it's a great machine the 71 looks like a upsized D61.😊

spent a few days in a komatsu dozer as a child sitting up beside the driver , we were reclaiming land , i was only 10 ......but i can still remember it well ...........bulldozers have come a long way since the mid 70s ........was a full body workout to operate one back then .......not to mention the heat and the noise ......

I have used CAT D6 for long but when I sat in Kamastu D71 I was amazed and I stack to it. The power this machine deliver and the view angles makes it great. I thing that is a worry on CAT D6 for every operator is the reverse view. It's only on you right and that makes you neck tired because you looking in one direction

Having operated Komatsu d61's,65's,68's lgp,85px/pxi,155's & Cat d5h,6h 7h/r,8n/r/t..I prefer the Komatsu tractors over Cat..I'm in no way trying to say anything negative regarding Cat as I'm fine with operating Cat..I just found Cats to be a little less balanced than the Komatsu tractors..The visibilty as you mentioned, I personally find better on Komatsu..Even with a 15 - 20 ft blade..I also have heard from numerous techs/mechanics that Komatsu at around the 16,000 hr mark can develop steering issues that can be a nightmare to troubleshoot There's other things,but again,it just comes down to operator preferences..Great video!!

Know next to nothing about dozers but an informative and enjoyable review.

They seem comparable mux. I suppose it comes down to price, servicing costs and dealer back up?

Great video lord muck top class well done

I am all for modern technology today, as you said Cat is a household name in the earthmoving industry but you cannot rest on your laurels. They have to watch it otherwise they will get left behind with the likes of Komatsu, Daewoo etc. Another great video.

There's a lake near Halls Creek in the Kimberley (Western Australia) called Lake Komaterpillar - because the dam that was built to make the lake was constructed by a Komatsu and a Caterpillar! Wonder if that was a Cat v Komatsu too?

He wasnt utilizing the GPS, but that takes it to another level if you use the Komatsu Proactive Dozing Control. Its a really nice feature to help newer operators be productive and limit wear on the machine. Works much better than the autocarry ive ran in a CAT.

Brilliant, not my world but every is a learning day. Thanks for your hard work 👍

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.

Great video as always must be something else if you have enjoyed the making of the video!!!👍 Be interesting to see if cat take up the challenge and what they come up with

Great video thanks.

Ive always thought the Komatsus dozers looked smart. Havent run one yet, but Im pretty sure its going go be the first on my list when I need to purchase one someday. Or the TCi 920. We shall see.

My uncle years ago had a komatsu d155ax dozer he absolutely loved that machine he also had a Cat d9g and a d8 he always said the komatsu would out push and out rip both the Cat dozers

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.

Enjoyed that Mucker and as Cat man in my plant operating days that Komatsu is the dogs danglies, and again I'm in agreement with you on the difference in the operators controls so its Cat controls onto the big K. 👌

ultimately it comes down to which one your boss likes and can afford

Another very interesting video to watch

Great video made a change

I've always ran can, a few old komatsu. But this past year I've had a 51, and would absolutely take it over a cat
