You can see how much work it cost to redesign the chassis. It's great that you managed to fit all these functions!

I'm most curious about how you will design the hood. I hope you won't let me down @I_Igor! : D

Current situation looks like this

...as you can see sloped front part of the hood resembles very well, but I need some additional slopes and yellow plates. Hope that I did not disappoint you to much.

Looks interesting!

Thank you 

Now I need some time to see what slopes and tiles I have and what I have to order to finish it. The main challenge was a part over headlights...

[1gor]

While waiting for parts to arrive, I have noticed that front part if previous version was to long, so I had to redesign it. M-motor is now placed vertical and I have tried to fit double wheels like on 2020 version but it looks to me it is to wide... Front drawbar would 90% be using work gear instead of linear actuator due to less space available (even rear is a bit to big)...

Hood is on the way, but sorry to kept you waiting...

[1gor]

While waiting for parts to arrive, I have played around blood lines using official brochure for 4 series Fastrac and discovered that previous hood version was to flat at the top, so I had to figure out something different. After several  hours of trial and error I have finally made proper top line curve for hood, but have to see how to fill gaps in future....

Sorry for rotated images ( but my mobile phone rotation to correct position is not recognized by brick safe...

Any comments are welcome, specially from @eric trax

As you can see I'm still struggling with front bonnet line; hope that yellow 1 x 13 curved panels from Volvo 42114 would help me make proper lines with (mostly) Technic parts...

As you can see on images I have lots of yellow panels but so far I could make curved line as I wanted (slope plates look like roof; they give discontinued curve so I'm not pleased with that...)

...to be continued...

[1gor]

...bonnet line finally suits scaled images of real tractor, but I need to adjust black and yellow color. Main goal was to make bonnet mostly with Technic parts as you can see ...

[eric trax]

This is a very good shape from the side profile, but the front with the lights falls too low compared to the original. Will you use side covers?

Hi Miha,

I plan to make longer front part (the one with lights), but it wold go over front chassis part (where is vertical M-motor). From side I plan to use plates to cover battery box as much as I can; keep in mind that bonnet is thinner near the cab... To get this shape I had spent dozens of hours (luckily I have all those parts in different colors so this yellow did not become loose ).

I really hope to finish bonnet in next 5 - 7 days and worm gear based front hitch... since few other projects are waiting...like smallest Unimog with new 68.7x27 tires (full manual version) or JCB loadall...or...

...one vehicle that uses both tracks and tractor tires...

[1gor]

Here is another version; not so curvy but proportions are much better; I'll probably make proper part over battery box with slopes 1 x 10 because actually "curvy" part is in the middle...

Sorry for bad photo quality... 

[1gor]

Since it turned out that proper line is very very hard to achieve without holes, I have another try but it is not finished due to missing some parts (which will arrive until mid of July). I use older bonnet as comparison with latest...any comments is appreciated...

What exact type of Fastrac do you try to MOC?

4000 series ...sorry for (very) late response but I work on 5 LEGO projects at the moment...

@eric trax I think I have made the most acceptable compromise solution for bonnet. I hope for better weather tomorrow to make better photos ... I hope you like it. (To many "I" )

(My Calico cat is very often in the way...)

Front bonnet is just one plate height to high.

Is it the final effect? I think the mask needs more slope to move, especially the grill and exterior light. Now it seems little bit flat.

It is a pity that there is such a small selection of yellow wedge bricks

The rear fenders should be a stud longer;)

Middle part of bonnet is a bit to flat (when I compare it to print from manual that I have it us about 1.5mm to low in the middle)...I do not understand completely what you mean about more slope on front mask?

Rear fenders could be one stud longer (at the back) but it would end up to flat perhaps...

Thanks for tips buddy

Yes we have to limited choice with yellow slopes.

When I look at images that I have (tomorrow I'll look at AGCO seller who has real Fastrac 4220 for display) it looks actually as a straight line (so I'll have to use black tiles) and not curved...so I think I can cover front positioned M-motor that drives front PTO

I think the mask is now much better

The cause of problem is that I can not make solution where "seat" panel and served slope plate would be on-line

[eric trax]

Much better Igor !! My next two suggestions:

- Place the pins and 1x4 tiles in the blue place.

- In the red place, insert the yellow wedge. It will be nicely rounded and a plate step will imitate the slope of the original hood

 

 

Another last suggestion. Please enter the stud length I mentioned for the rear fenders here. This will not affect the fender's curvature optically.

@eric trax this part https://www.bricklink.com/v2/catalog/catalogitem.page?P=29120&idColor=85#T=S&C=3&O={"color":3,"loc":"HR","iconly":0}

is not on sale in Croatia, but Audi Quattro set is available so I could buy this set...

Front part to be covered with tile 1 x 4 is possible but before that I'm working on rear fender on exactly the same place that you suggested with 2 axles 3 and 2 liftarms 1 x 4 on each side...

Thanks 

I hope to find Audi tomorrow and to finish this build. I have an idea for telehandler arm with included m-motor for attachments tilting (and possible grab arm...)

I saw that you commented on my topic and it made me remember that you were working on this JCB. Glad i found your thread again because you have made great progress on this tractor

Actually it is on standstill because of my work (lots lots of preparations since middle of July for new school year and complicated way for doing lessons due to pandemic situation)...but positive is that I made new chassis featuring Technic battery box and I prepare cab to be tilted forward to enable access to battery box... Still wondering where to put m-motor for rear pto...and receivers will be part of cab. Front bonnet has more space now for new (re) construction with 3 x 7 panels from Volvo loader which are on the way...

Kind regards

At a stand still for now, just like my IH 'snoopy' or 'anteater' (thread seems to be lost) but i'm sure you'll find some time and motivation in the future to work on your JCB again.

Today I made prototype for cab evolution to save some parts and I'm happy with it. The most challenging thing is hood and rear axle; 3 point hitch should not be to big...(and also the front 3ph)...

So you've already found some time ?

Curious to see some pictures. I can understand that the hood and 3 point hitches are a challenge. Space is pretty limited Indeed.

Yes! Thanks you! I could not find it with the search function or in 'my activity'. I'm glad the thread is still there including pictures..
