[MOC] JCB Fastrac 4220

[MAnd]

I want to present a model based on the new Fastrac 4000 series of JCB. The Fastrac 4220.

The original Fastrac:

My LEGO Technic rebuilt:

I will post some more pictures and maybe a video when I am back home.

Dimensions:

L: 328 mm

B: 176 mm

H: 220 mm

Following functions are included in the model:

Liftable/lowerable front and back 3 point hitch powered by pneumatic cylinders and 6L pump.

PTO in front and back powered by XL motor.

PTO and pump function is controlled via gearbox.

2 hose connectors in the front and 4 in the back.

All pneumatic functions are controlled via the valves on top of the cabine.

front steering system with torsion bar based front axle.

Liftable hood.

4 cylinder engine driven by rear axle.

Enjoy!

I like it very much. I only mising a video of all this functions.

[KamalMYafi]

Very nice model! Please add more pictures and video.

[Robert Brick]

Nice work! And what about driving? forgot to mention or no space in the model?

I hope you like it!

It is very nice, but I see that hood is causing you a bit of trouble like on my model...OK I need to make proper steering with 3 modes..., but live axles and 6 cylinder engine are done (together with main chassis part). Just one question - did you made suspended axles?

I am full agree.

Maybe I will add one in the future.

Sorry about that. Of course driving is also available as front steering system.

hood is not making any trouble at all, it is completely stable.

suspended axle is also implemented: it is a torsion bar system.

you jumped the gun! The new tires from the Claas Xerion will be out later this year.

-- Kidding, this model looks great. Would love to see it with the new tires however. Also, the functioning sounds great, but like others have said, video would be great. I know it may sound tedious, but there really is only so much we, as an audience can enjoy, from pics only of a great Technic build such as this one.

The new tires would be way too big for this model. The scale of this model is based on the Volvo tires

I believe that hood is very stable, but it is not smooth like on original one...I hope that I can find time to take pictures of my axles within chassis and post them - maybe my solution could help someone who reads this tread - of course with your permission

Yeah I would appreciate that.

Concerning the hood I understand what you mean.

I did not implement further steering methods because I had absolutely no space for building this in such a compact model.

But I am not the best Technic builder so maybe I missed something.

Yeah, space is also bothering me, specially if I want to motorize some functions like on Unimog, you'll see when I upload the pictures. I have Idea for steering similar to LEGO Xerion, but need to find time 4 LEGO

[hocks]

Very nice model, tyres are of putting a bit but you can only work with what you have ☺, great job anyway.

[wesyr]

I very like it! Good job man.

[GroundskeeperWillie]

Looking good Would be nice with a few more pics and a video.

this is my idea of how axels should be made (if images are not lost on the way...)

Great Moc. I like the accessibility of all the pneumatic valves on the top of the cab.

[KamalMYafi]

If you want to make the picture not lost, do not attach them because the Eurobricks site limit is 100k and you aren't supposed to use Eurobricks as a photo host. The small allowance is for an avatar image and Lego Digital Designer files for sharing. If you use an external image host and then link then deeplink the images (see this) then there should be no issues.

[Paul B Technic]

You have done an amazing job with this, I love the level of detail.

[MAnd]

That looks good man.

Hopefully you have enough space to implement further features.

I hope so, but yesterday I realize that I had to redesign central part and put central differential in in and whole linkage for steering something like on Barman's Xerion steering interpretation. Only difference is that I use 94.8 X 44 tires (the one from crawler), so chassis should be as narrow as possible

I know that, but this image was just meant to help other builders if they want to do something like that. It is not finished version, so I'll make a gallery (not on Eurobricks) and link them here. thank you four your good intension's and info
