I really want a cat, but since I already have a german shepherd, I guess I'll settle for this.

[@OfficialDjAVE]

Unbrickme?? This must be a lego technic KZbin channel crossover !

[@McKrushi]

But it has a gearbox?! ;)

[@sitsia3808]

Nice one

[@conceicaodias6274]

Oh plz shut you are a hater of lego

[@R1pp3d]

I feel like there's always a compromise between building experience and playabillity, adding a motor for every function makes the build less interesting imo, but makes the set more functional. I don't really have a strong opinion on this set other than that it's expensive.

[@Ntgaming26]

i think that if it wasnt using those mechanical pistons but pneumatic pistons and 1 motor plus a pump for making air pressure you could have better function but also a more interesting build

[@michaelfoulis7438]

@@Ntgaming26 If they found a way of making it powerful enough to move parts of the model and work through the app it would be much cheaper and better

[@afurryball]

Another amazing review! Endless apprise for remaining so UNBIASED all these years when it comes to reviewing Technic sets! Even though you get early review models from the Lego group. Also, the amount of work you put into each review to make it so detailed is beyond imaginable. Thank you.

[@Unbrickme]

Markus Kossman is the best! I'm so glad that he worked on this bulldozer as he designed the 2007 one as well! I have so much nostalgia for the 2007 one, and I love the gearbox so much in this set! Definitely the best model designed by kossman!

We could all really use this set for when we tip out our lego onto the floor and need to push it back into the box.

[@Richard1855]

I work for a Caterpillar Dealer in Australia and CAT (that's what the manufacturer is called by dealers) has informed us that they are changing the naming convention of the entire product line. So this bulldozer, or correctly called Track Type Tractor, will now be named D11; distinguishing it from the proceeding model D11T. CAT have dropped the alphabet at the end, going forward. A bit of trivia for you. Thoroughly enjoyed your video and comments on this model. Looking forward to your next video.

[@RacingBrick]

Thanks for the information! Based on this the box design should be changed to the version we see online

[@thecarspot8768]

@@RacingBrick not trying to be rude but this is fake as lego said a few days ago that this happened s not one of their sets and you can tell because it shows on the front of the box that they don’t have an app to remote control any of their remote control vehicles but they have a controller instead and that’s how you you tell this is fake lego technic set

For me, the ultimate functions straight out of the box is the Excavator model. Crazy mechanism

[@jakubpollak2067]

4:37 I think that in this case, it doesn't matter If you flip the grey cog around, it will just invert two times = rotating same way in the end

[@leochin9649]

thank you master, waited for looooooooong time

[@ygrbooks]

Thanks for this video. I have just finished building the RC-Bulldozer by Happy Build® 22011: 7 motors, two hubs, RC (and some kind of "Control+" if you so wish), rechargeable batteries and excellent parts at a price of €180. It is a MOC that went into serial production, so it is not perfect in all aspects of the build, but it works fine. This means that I will not ever be needing the Lego version as it has fewer functions, no RC, no rechargeable batteries, fewer motors (which you are not free to use for whatever you want unless you buy additional stuff), just one hub, a sticker sheet (but no Cat prints - if I understand you correctly) and costs the princely sum of €450. It is just a no-brainer.

[@whatiswrongwithwhatihadwankers]

Is Happy a lego product, if not I don't get your point.

[@francis9131]

I feel like they should have motorized the ripper tilt and made the ladder manual. I do like how they managed to get 6 functions out of 4 motors (saving the cost of 2 motors and an extra hub). Overall, the looks are amazing. The price tag, not so much.

[@chrisbushnell2378]

The ladder is motor driven on the real thing though

[@jakobhassler6139]

Yes....so cool

[@TechnicBrickPower]

Beautiful set - thanks for showing such a detailed review. It's a very exciting set and I like the new tracks with extra grip. 🙃

[@Tusconforklift]

Love your content my friend, I got this last year and built it once before. So after watching your video I decided to take it apart to re build it again. I forgot just how many pieces this set consists of, lol one of my favorite builds.

[@Nova.1971]

D11T would correct for CAT's latest model. The black on the blade would a CAT Carry Dozer option. Can't wait to get this.

[@M3dicayne]

4:39 Nope. That's just a differential with only 3 gears. You can even add another frictionless gear and it works like a charm. Also, I don't like Lego's price at all at this point for a technically incorrect version where the drivetrain is just on the wrong wheel...

[@spudmaphot]

Nabbed this bad boy for 250 euro (373 CAD). This is my third technic set and the first over 1000 pieces. In the process building it and the second step where you build the majority of the mechanism caught me unprepared in its complexity. Made two big mistakes that were not easy to fix after getting much later in the build. It was both great relief and satisfaction when the testing step came and everything worked 😅

[@Dan-c7w]

D11t is another configuration of the d11 with the acert 32 engine. It is the correct nomenclature for this dozer…

[@arghjayem]

Finally a set to use as the basis for a MOC to recreate the House robots from Robot Wars!!! 😂🤣😂

[@Cricketbadger987]

I was already getting Shunt and behemoth vibes watching this 😂

[@TheMetalButcher]

Blade shouldn't tilt forward back, but side to side. It should only have an actuator on one side and fixed on the other. I guess that would have added a fair few parts.

[@Dylan-zj1lz]

4:32 it does not matter the direction on the grey idle gear for the linear actuators. As all it does is transfer the rotation from one side to the other… it’s an idle gear, the direction would only matter if that gear was the drive gear.

[@awes0men0b0dy9]

This is a amazing set from what I’ve seen the climbing and driving ability is amazing and the functions and details are good the only bad thing is it’s overpriced if it was maybe 50-100 dollars cheaper it would be one of the best technic sets ever I would just wait a little bit and see if it get slightly cheaper

[@skiwiepiwie1862]

I prefer the rough terrain crane I kind don't like powered up motors and the crane has alot of gearboxes to make it more interesting

[@Starling_54]

Dang, that box is huge

[@Worldwave]

yay another racingbrick video. thanks dude! I really enjoy the technic reviews. I love your commentary too.

[@xy_iron]

in my opinion Liebherr is a much better deal. You get 300 more pieces (100 of wich are 2x2 round bricks), 2 hubs, 7 motors and each function has its own motor so you can use all of them at once. I think only advantage of D11 is the new tracks

[@lawrencedoyle7172]

Im not keen on the model.... But I will buy 2 or 3 of them and make my own MOC bulldozer with them with more tracks, power, pistons, track runner wheels and a tripple ripper with tilt action...... WHAT DO YOU THINK.......

[@iRoyalCoconut]

Buyin this tomorrow to add to my collection of unbuilt legos 😂

[@Curtis_day]

I have driven a real life version of this but it was a D9 and its like driving a tank and it feels like nothing can stop it cuz it cuts through piles of dirt like butter and knocks down trees like they are not even there

[@BreaksBee]

[@coffeeinhandproductions3238]

Great to the point review. Surprised how big this thing is, and the functions all seem to work pretty decently. Good job Lego.

[@dennisberg2474]

Very cool, but I agree a $350 price would be far more appropriate than $450

[@JSLEnterprises]

My last technic model in my youth was 8857 (the street chopper from 93, however I still have the set in its alternate dragster form); unlike that one, I find all these new sets have blue, red, orage, and a plethora of other multi-color parts, which is fine if you're semi-blind from age, or if you're attention span is that of a goldfish where you cant focus on any specific area to notice the details when its all the same or similar color. Given that these are 18+ builds, that cost upwards of $500, 1) they should have same-color-parts for where they go in the overall, 2) All pieces that currently get stickers should have actually been printed (like the Ferrari)

[@lordprecliktwo7332]

My second favorite technic set I've built! (first being the rough terrain crane). now, if only we got something in this price range THIS year, rather than the insanely overpriced Liebherr crawler crane. half the piece count as this set but has all the hubs and motors lol. i'd rather get the Liebherr excavator or bucket wheel excavator for $700.

[@billynomates920]

[@willemlu]

Thanks for another great review! Normally I skip the building part of reviews, but your modular build approach with explanations is very interesting, so I watched the whole video. Excellent idea! 👍 Another overpriced Lego Technic set. For this price it should have had extra hub/motors to power additional functions. A shame, but at least it is a true flagship set …

[@fishbrix3809]

true

[@Polsnulspace]

This is top of my list at the moment but it still needs to drop in price quite a bit before I make my move. I'm hoping for £260-£270 just like the Liebherr Excavator did.

They add the white box into the bigger box to keep its structure and support the weight of being stacked.

[@FurTh3r]

The thing you said at 4:39 is not true, you can put the gear in both the positions and the result is perfectly the same (You could use two gears instead of one there one facing the other and they turn on opposite directions, but still same result (this mechanism is used in differentials : D))

[@Motologist95]

It's strange to me CAT chose to use a D11 Carry Dozer in the instruction's photos. The set is set up in the most common configuration with a U-blade and single shank ripper. A Carry Dozer with triple shank is a far less common configuration.

[@CandiceMcLean-s3c]

The reason why it doesn’t go all the way down is cause. See that gap on the fake hydraulic and it’s colliding and stopping it from going all the way down. take it off and it will go all the way down.

This is a one of the best Technic sets ever. Much better, than the excavator.

[@awes0men0b0dy9]

I got this from grandparents but mine was missing one of the bag 1s I am so bummed now I need to figure out how to get the replacement parts from LEGO customer service. I am excited to make this as I have built LEGO guns involving lots of technic and have the hovercraft and small race plane but this is my first large technic set. My grandpa said he choose this one bc “it’s the one with the highest age recommendation I’m only 14 but have been building LEGO since 6. I hope I figure it out my missing bag soon I could have lost it but I turned my room upside down and back to find it but can’t so I’m assuming I’m just 1 in thousands maybe that had a missing bag

[@xaytana]

The track tensioners are a surprise, probably the last thing I expected from this. Still a disappointment that the blade lift doesn't have a new xxl linear actuator, and instead a half fake actuator. The collision of the blade with the fake portion of the actuator is an absolute joke, reminds me of the Osprey's destruction of gears, or the Zetros' rear diff carrier allowing for gears to unmesh under stress; poor design is really starting to become a consistent theme, isn't it? The ripper is also a disappointment. I'm also still disappointed that Lego decided to throw the 18+ tax on this when the price could've instead covered a second hub and given us blade lift, blade tilt, ripper lift, and ripper tilt as separate, simultaneous functions. The design is alright, I guess, some of the techniques are a bit odd, though. What I'm curious about now is the performance of the new tracks, especially on hard, smooth surfaces. I'm also curious about compatibility with the rubber pieces that Lego uses as a bandaid for their poor track design.

[@paologalbiati3782]

The rubber pieces are useless because they can't touch the ground. Sariel show it in his review.

@@paologalbiati3782 Ah, yes, mention another content creator entirely, where there's a fairly large chance that a person hasn't watched that creator's video or doesn't even know of said creator. Hmm, I wonder why the original comment mentioned the rubber pieces in the first place _on this video_ when they could've just watched Sariel instead. Maybe it would've been better for this content creator to have shown this flaw in the original video that this comment exists on. Also, Sariel only showed the rubber studs, not the much taller rubber bars, and I wouldn't be surprised if the bars are tall enough to surpass the new track flanges. Rub a couple of your brain cells together, this is simple logic, it's not that hard to figure out.
