Wow, I am not really into construction equipment, but this one looks really nice

Great MOC! Stunning design and functions!
But video has very unnatural colors. It was too much-lightened light I assume.

Probably yes. It was my first video, so thank you for useful advice. I'll remember that while making other videos.

And I'm delighted that you liked it.

Thank you for not building another RC model (I don't respect RC, except one model)!

However!

1) The steering radius is too big. Considering a tractor has to be very manoeuvrable on a construction site.

2) Your tractor doesn't have a seat, control panel etc. It's normal for a technic model. So why did you build the steering wheel, if you don't have the other cabine stuff? It makes no sense!

Nevertheless overall you did a good job!

1) it's a model with a lot of functions crammed into such a compact space, so i'm hardly surprised it's hard to get a tight turning radius

2) look at all the cables there. there's no space for a seat

1) So why did you not build a model with smaller front wheels, that would let you make a proper steering radius?

2) Yes! If you decided to build a model without interior - it's normal. But be consistent! If you "removed" a seat and control panel, then you should have removed the steering wheel as well!

Strictly speaking we have two conceptions:

- complete interior

- no interior

You chose something middle and it doesn't look well.

But there is no sentence which says ''It's finished'' so I still can build the interior.

1) Well because obviously he wanted all four wheels to be the same size

2) Personally I don’t think it matters anywhere near that much

1) Then he had to find a way to make the same size wheels work well.

I gues it's my mistake. The model looks a lot like it was based on my Backhoe, but this mod has definitely better bucket proportions than mine.
My model has a seat, but it has less pneumatic functions, so that might be the reason for ommitting the seat.

Nice loader, but why just one picture?

Isn't there some filtrer apllied?

I dunno if it’s the language barrier, but it kinda sounds like you’re dictating what he should be doing.

Like I said before, he probably already tried but couldn’t find any way to do so; the front part of a backhoe is quite compact.

We all are sharing our opinions here, aren't we?

His wheels simply don't turn, how can I ignore it?

It means he made some mistake when projecting his future tractor. And somehow he kept building it despite the awkward steering.

What makes you think he didn’t already try? Perhaps he couldn’t come up with a solution and decided to settle for a compromise?

They turn a lot, but you simply didn't notice it (the video doesn't show it well). 

It has got 4 wheel steering which works exactly like this:

Yes. I have downloaded your 3D model. Your backhoe is well designed as complete version, but If you want to change something you have to rework nearly everything. By the way the front suspension wasn't changed, because of genius mechanisms. 

[mpj]

It looks very solid and well designed!

Yes maybe steering is not perfect. Personally I don't like the not-Lego wheels, but I like everything else. Well done!

[Aris]

Is so extraordinary that i didn't notice the steering . Excellent work.

It is very nice model and only thing that i would do on my MOC is base it on Unimog tires like @Lipko's, but it is your Moc and IMHO you made great MOC
