LEGO Technic Cat D11 Bulldozer 42131 Reviewed!

The LEGO Technic Cat D11T Bulldozer is some of Markus Kossmann's best work, containing amazing mechanisms, incredible engineering, perfect aesthetics, and more! That being said, is it really worth $450? Personally, I have tons of nostalgia for the original, 2007 power functions bulldozer. This set blew me away in terms of its size. I did not expect it to be so massive! On top of that, it contains an advanced gearbox, which is definitely an upgrade over the 2007 one.

I work for a Caterpillar Dealership and in the actual machine, the blade lift IS slow, so any modification to speed it up would make it not realistic. The actual machine does have a blade safety feature to quick drop it, should an emergency arise whereby the operator need to stop the machine quickly.

If you wished that the track tension knob was motorized, you can attach the medium angular motor from the Lego mindstorms 51515 set. You can remove technic hub from the lego technic bulldozer and attach the lego mindstorms Robot Inventor hub so you can have more ports to connect the motors. 0:45

It would be nice if the gearbox could engage multiple functions at once like on some other sets, and it would also be better if the motors drove the sprocket gear instead of the rear idler.

New Hub Firmware for CAT control with Lego 88010 remote in Eurobricksforum unter „42131 - CAT D11 Bulldozer“
The idea with LED function indicator is clever.
Remote's +/- buttons to directly control the treads. The red buttons control the active function. Pressing the green button cycles through the four functions, and the remote's LED indicates which one is active:
* Blue: blade lift
* Green: ripper
* Yellow: ladder
* Red: blade tilt
* White: function switching in

Terrific review. Comprehensive. First review I’ve seen showing the pushing power of the dozer with sand. It was surprisingly impressive. Looks wise you’re right the designer has nailed it. The Leibherr actually looks small in comparison. But …….£419 is too much.

Imagine if the dashboard sticker was actually a tiny version of a phone with the Control+ app. That'd be a neat little easter egg that I feel like lego should implement.

Well the rippers do technically have a tilt it's primarily there just to keep the ripper assembly vertical at various depths so I can see why they skipped it in favor of the ladder

[Steven-kzec]

I have mine finished on Saturday, considerate it lacks ripper till function, over prices for sure, but overall it’s a good set.

i love my 42131. aside for some track tensioning issues/tracks coming off, that is. there seems to be a sweet spot for the tensioning that is tricky to nail down without spending more time fussing with the tensioner than the actual set. i think they optimized the blade lift/lower speed just a bit. still slow, but maybe not quite a snails pace.

Im machine operator (excavators, loadera, dozers)

The way you operate dozer is, you set throttle and then use brake pedals to slow one side in order to turn, or you can use joystick (at least in new machines)

Same price as the 42100 Liebherr excavator but having 1 hub and 3 less motors not to mention less pieces. Should have been $299-349 IMO.

5:49 Whoops, the track fell off. Surprised you didn't mention that little mishap.

[drus]

the 42131 is not entirely 1:1 scale. it has 12 roadwheels. the real d11 has 16. the ripper looks fragile and half done. they could have made an impact ripper. it was heavier and longer. and the very large and high volume yellow blade u see inside the manual is a coal blade. the 42131 has a normal blade.

[Lia-sfqc]

In the next video you can do “why is control + overpriced” or “why is the d11 bulldozer overpriced”.
PS: you are definitely my favorite lego youtuber

[clarkwilliam]

Just bought it today, looking forward putting it together!

[sliperi]

can I move the bulldozer manually? For example, when the hub breaks down…

[drus]

i will use the 42097's outriggers as pistons (8 of those are needed). and those can also be used manually.

[LegoHeadProductionsAZ]

Hi unbrickme! I wanted to ask you if there was a way to keep the LEGO mindstorms ev3 on 24/7 because I built something that requires that.

[drus]

instead of the ladder, they could have made the ripper entirely functional

[landonrobertson]

I have this same set and the right tread keeps making this annoying clicking noise, and when it does click the right side kinda "hops". It got passed down to me from my dad's boss, and my dad's boss got it from his neighbor. I do not know what is wrong with it, and if anyone knows what is wrong with it, please let me know.
