This is absoultley stunning! The amount of functions and the realistic looks are amazing!This has to be the the best bulldozer MOC that i've seen

[weavil]

You fought the beast and won! It looks big and amazing!

[Ramacco]

Marvelous

Nice dozer Jorge.

I too would like to make a dozer,a pneumatic one as well.But who knows when I will get the time....

[jorgeopesi]

Thank you for all comments , I want to see that dozer Alasdair. A few pics more.

This thing is just awesome! Great work

[MVtechnic]

It's just beautiful. Awesome job !

[legomuppet9]

Superb. Great work Jorgeopesi!

[MrNumbskull13]

Wonderful MOC, crammed with functions!

[Lakop]

Well done. That is up there with all the other mammoth dozers and excavators I've seen. Truly brilliant and it will inspire others to build to that scale.

The best excavator built out of lego I've ever seen. Amazing job!! :thumbup:

Absolutely awesome! I almost expect heaps of black smoke and a growling 12 cylinder diesel engine sound in the video!;-)

, with such internal mechanism I had not have enough room to put a 12V fake engine . Thank you for your comments, what I really want is more people doing heavy machinery.

Very nice MOC! I especially like the tracks. They look like they provide far better traction than the regular track links.

Very, very nice MOC. Well done! Is there any chance of you creating (paid) instructions?

By the way, I like the functionality of the tracks - seems to provide good traction - but they seem a bit too 'narrow'. Or is it just me?

In fact is the opposite, the tracks are a little wide in proportion with the real one, everybody thinks that machinery tracks are wide and they are very narrow. They have too much traction and they give me problems when the machine turns, I need another ones more rigid and narrow and I think that... obviously in black but I have to wait for the pieces .

It is a expensive MOC and I don´t have any idea to make instructions sorry... for the moment... .

What is the black part? Rigid hose?

Just plastic and no rubber may not provide enough friction. What are the problems when machine turns? Tracks tend to fell off the sprockets?

Rigid hose yes and just this is the problem, I have to do more rigid the tracks because they are too elastic or use more red gears, 2´5 kg the machine...

Great looking machine, although the front blade looks almost too big.

Can't you just use 4L bars to avoid cutting tons of rigid hose?

[jorgeopesi]

No, There is no room between 4L bar and 4L bar for the yellow gear teeth if you use a rigid track, believe me I have tried everything about custom tracks...
