Awesome build and looks! How did you connect the wheel axles to the differential? Using CV joint from the hub and then U joint? If so, how do you keep the differential in place? I tried to build the front axle for the Ford Raptor RC mod in the same width but couldn't make it fit and had to place the differential longitudinal in the end.

I build a new chassis for the Raptor to make it RC and 4WD with lockable differentials. More details in the topic:
-
Contrary to many people I actually quite like the looks of the F-150 Raptor set, and decided to build a new chassis for it to motorize it. I wanted to give it plenty of power, a working steering wheel (I'm always a bit disappointed with models that don't have a functioning steering wheel), and it seemed like there was quite some space so I wanted to have some extra functionality, therefore I added differential locks on all three differentials.
The truck has four wheel drive, with differentials on each axle and a center differential. All three differentials are lockable. The suspension has remained roughly similar to the original model, with double wishbones in the front and a live axle in the rear. The steering wheel in the cabin is also connected to the steering and moves with the wheels.
The steering and locking differentials are each powered by a control+ L motor, two control+ XL motors are used for drive.
The control plus hub is easily accessible under the hood.
To make everything fit I had to give up the rear bench (the lock for the center diff is 2 studs too high to make it fit), and I had to sacrifice some ground clearance in the middle of the chassis and on the rear axle.
The axles where the most challenging part, in the front because the model is not wide enough to fit a differential, U-joints and CV joints, therefore the front differential is placed longitudinal and connects to the CV joints using bevel gears. In the rear, the problem was that the front axle has a 1:1 ratio from the wheels to the diff, and there was no space left in the chassis to increase the speed of the driveline before it goes into the rear axle. That meant the rear axle also needed to have a 1:1 gear ratio, which was very challenging. I managed it in the end by using two 3650 24 tooth Crown gears being driven from a 16 tooth gear on the driveline axle and driving the 16 tooth side of an old differential with the same crown gears.
Overall I'm quite happy with the result, however if you go from full speed forward to full speed reverse the crown gears still slip. I'm still doubting if I will give reinforcing the bracing of the gears another go or if I'll leave it like this for now. I'm also still doubting whether I will rebuild the chassis in better matching colors,
Let me know what you think! And if anyone has another idea on how to make the rear axle with a 1:1 ratio and space for the diff lock I'm very interested :)

Or if you have a gamepad / playstation controller lying around, use the brick controller 2 app made by by @imurvai
-
@imurvaiThanks for the awesome app! Especially like the ability to combine different hubs / units in one MOC. On that topic, any plans to include support for Circuit Cubes? the small motors and small hub might be ideal on some part of a moc (on top of a crane, in a trailer or attachment for tractor for example) while the main part is controlled by buwizz/sbrick/control+ hub.
Edit: Found this topic by @Asper suggesting they are willing to share the details of the bluetooth protocol!

I don't like stickers (or too specific parts for that matter), with a few exceptions:
- On small common parts, used for cool detailing, like license plates, or logos
- On (e.g.) tiles to explain functions
I especially don't like stickers on bigger parts, and what is really the worst is stickers spanning multiple parts, but I haven't seen that since my childhood

2 hours ago, I_Igor said:Now it looks much better
but as I'm come complicated mocer there are two things that I do not like ( it is not your fault that TLC does not produce those parts); front balloon tires and light bluish gray rims instead of white...
Regards
Thanks! Yes we should definitely get better front tractor tires. That bothers me more than the rim colors I think...
44 minutes ago, TeamThrifty said:I'm loving the recent tractor action on here!! They are my favourite and what i usually build... I know its controversial, but i think there's a special challange with tractors. Cars are 1:8 scale, big with loads of room to fit basic suspension and a gearbox in. Tractors are 1:18/1:20 ish.. and need 4wd with a clutch, diff locks, front and rear 3 point, pneumatics, steering. A much more considerable technical challenge if we're all honest!!
Great MOC by the way! Keep the tractor faith!
Thanks! I agree, that's why I haven't bought one of the super cars yet. Although for me it was already a big challenge to fit six motors - I would have no clue how to add four wheel drive, front 3 pt and PTO and diff locks in the same space, let alone pneumatics for attachments...
Anyway my next project is about halfway the 'design' phase (building with whatever color is available), it's not a tractor or attachment but I think it will look cool together with this one. Its in yellow / dbg l black because I have to find some use for all those BWE pieces
-
It has taken more than a month, but all of the orders have arrived, and I've found the time to rebuild it!
This is what it looked like last night when I should have gone to bed:
And this is what it looked like when I actually went to sleep
Next up is to take some better pictures, maybe a short video with the functions and start building some attachments
-
Finally found the time to fix all the expensive parts! Replaced everything on the list above, and a bit more. Sometimes it was just changing colors, but the roof and the side tanks had to be rebuilt.
Here's the result, spot the differences
.
Not quite happy with the look of the roof compared to the previous version, but those blue 5x11 panels are really to expensive... And I don't have the container truck that has them.
Anyway, it took a bit longer because I had to built my birthday present in between - thanks to my lovely wife!
All the bricklink orders are finally out (ouch, that still hurt my wallet...) for the parts in the right colors, so now the waiting game begins again.

1 minute ago, I_Igor said:@Arie the front defenetly, and the rear? It is question of scale; most tractors are 2550mm wide (exceptions are JCB Fastrac 4000 series with 710/60R30 tires and JCB Fastrac 8000 with 650/65R34 and 900/50R42 tires - they are 2750mm wide)
Hmm you're right, in that case the track width is about two studs too wide. I only have a blueprint with a sideview... A well, that is something for the next model. Lesson for next time, get the wheels in the right place
. And for now, let's just say that the wider track makes it look more bad-megablocks 
I also just finished a render of the rear view, can't wait till it actually looks like this
Biggest part / color selection mistakes so far: (price-wise)
- Black axles #7 --> OUCH
- Blue 1x4 thin liftarms
- Blue 5x11 Panel
- LBG Non friction Axle-pins (I have a lot of old Light Grays, and they looked much better than the new tans, but obviously LBG wasn't the right 'compromise')
- Black, DBG & Blue perpendicular Pin connectors 2x2 bent (44809)
- Blue technic brick 1x2 with holes
- Black Axle towball
- White axle #3 & White technic pin 1/2 --> Those just didn't have the right color assigned yet
Looks like 90% of this is fixable, and for a few parts I'm just gonna have to pay the couple of euro's per single part price...

That would be really great... Those balloons just look wrong. I saw some pictures of Eric Trax / M_Longer model with 3rd party tires and it looked so much better!
40 minutes ago, I_Igor said:I was hoping for that when in 2016 it was announced that LEGO and Claas made an agreement...yes we defenetly need 81.6 and 94.8 tractor tires, but we will see...
BTW very nice MOC @Arie. Somehow it looks like tires are to wide for scale.
Thanks! Do you mean the front or rear tires? The front definitely are way to wide, the rear is quite OK I think:

Hi Everyone!
Edit: Tractor is now finished, instructions are on rebrickable: https://rebrickable.com/mocs/MOC-97159/Arjo/rc-new-holland-tractor-with-front-loader/
Original post:
My first post on this forum about my first (serious attempt at a) MOC: A New Holland Tractor with Front Loader. For a large part it is inspired by the TM140 by Eric Trax & M_Longer, from which I 'stole' the tire choices, and the design of the rear interfaces, such that attachments are compatible. It uses however a lot of system parts that I don't have
and I really wanted a frontloader for playability.
This is the result so far:
And this is what it would look like if I had all the parts in the right color already
The model has 6 motorized functions, controlled by 1 Buwizz and 1 PF receiver:
- Driving (L-motor)
- Steering (Servo motor)
- Lifting bucket (M-motor)
- Dumping bucket (M-motor)
- PTO (M-motor) (with clutch gear)
- Three-point hitch lifting (with clutch gear)
Other functions:
- Pendular front axle
- Foldable front tow hitch
- Openable doors
Next steps are to try to replace some parts that I accidentally added because I only checked if they exist in other colors and not their price.
. Then, order all the parts in the right color and build a proper model!
Why this topic? I would really like to know what you guys think and appreciate some feedback :)
