Fantastic mini tractor. I really like how you design the tracks. Good job!

A very interesting choice! I love the design of this machine and I'm curious about the end result! :D

This is rather an approximate number of bricks. The prototype had 4,459 bricks and I know that in the end there will be a dozen more, so I think it will be closer to 4,500 elements in total. More funny is this part of description: "crafted by the esteemed MOC studio Eric Trax" Now I have no choice but to start up a design studio

I think that nothing bad would happen if you used identical tires on the front and rear axles :) Fair enough! I like the trailer so much that I bought bricks for a second copy to test the instructions :D I used old hubs. The turning radius is small because the tractor does not have front drive. This allows the front wheels to turn so much

It's time to show something agricultural. This time it will be a rather unusual JCB Fastrac 3185 tractor and an Oehler ZDK 180 trailer. The tractor model has been on my shelf for almost two years, so it's time to show it. For comparison, a photo of the original: JCB Fastrac 3185 I must admit that the Fastrac series are some of my favorite tractors. I remember being fascinated by them in agricultural newspapers as a child. What impressed me the most was the fact that they could accelerate up to 80 km/h. These tractors are loved or hated mainly because of their appearance. The 3185 is definitely my favorite. I started building it when it was already known that agricultural tires with a diameter of 81 mm would appear with the 42129 set. The frame was built quite quickly and is significantly different from my previous tractors. I removed the front three point hitch and added a front pendular suspension. The tractor is powered by an L-motor, turns using a servo-motor, and the lift and PTO operate two M-motors. Everything controlled by Sbrick. Then I started building the cabin, which has a rather specific shape. I managed to reproduce it quite well and I am fully satisfied with it. The cabin, of course, has an equipped interior with two seats. The biggest problem I had was with the design of the tractor's hood. It has a specific arch at the front with gille and thin frames on the sides. First, I made it with a sticker, but during one of the exhibitions I came up with the idea to use rounded 1x2 plates. It was a good decision. From the beginning, I didn't plan on making a building manual for it due to the complicated shape of the cabin. I finally changed my mind. This required further corrections, but they were implemented quite efficiently. My reluctance to follow the instructions was also caused by the printed fenders that @SaperPL made for me. Not wanting to cause problems for people who would buy the instructions, I built equivalents from Lego, which increased the number of elements by 130 bricks. The final effect, especially after using the stickers, is great and I must admit that it's probably my favorite tractor now :D OEHLER ZDK 180 Such a long delay in the publication of Fastrac was also caused by the lack of a machine to complete the set. I wanted to build a construction trailer, but I decided that it would be quite similar to my previous Krampe BigBody 550. I did not have traditional trailers in my collection. I kept thinking about an unusual color that would contrast nicely with the yellow tractor. I chose OEHLER ZDK 180. I decided to build the box with 23405 panels, which imitate the sides of the dump box well. Surprisingly, the dimensions of these elements matched the dimensions of the model quite well. The dump box had to be reinforced, of course, otherwise the load would burst it from the inside. I used additional strips so that it is now very stable. The visual effect well reflects the appearance of a real trailer. The dark turquise color is slightly different from the one used in Oehler trailers, and in the photos it looks much bluer than in reality. The dump box also has a side locking mechanism that works like in a real machine. The difference is double-side tipping.The real trailer box tilts in three directions. At the beginning of the construction process it also tilted backwards, but the use of a medium linear actuator made the whole thing very unstable. Finally, the box is lifted by two small linear actuators powered by the M-motor. The maximum load I tested was 4.5 kg. I must admit that this is quite an impressive result. Another interesting fact is that I used 67.8x27 tires, which are a bit larger than they should be, but because they are wider than the 62.4 mm tires, they significantly improve the overall appearance of the model.

The answer to your questions is quite simple. This model is much smaller, so it does not qualify for the MASTER series because it has much fewer bricks and is simpler to build. The box is decorated similarly to the Master series because the product is licensed and even despite its small size, CADA wants it to look as good as possible. I almost didn't notice it. The set is also intended for younger children, so the color coding is an advantage in my opinion. You can always replace the pins with black ones. I also use the color coding on my CLAAS combine harvester. Maybe it's not visible at first glance. With color coding, building is much less frustrating. I know it's the Master series, but the pleasure of building is also important to me. For example, that is why I divided the combine frame into four modules that connect into one whole to make the construction process more friendly.

Fantastic compact design. What deserves recognition is that you used pneumatics, the operation of which takes up much more space in the model

2x Control Box + 7 motors + physical remote + app profile for android and iphone. All JCB logos are printed on tiles. Fun fact: I designed the operator's cabin as a completely separate model for fun during the building process. You can detach it and place it next to the excavator :) Undercarrige: Control Box + 2x micromotor for each track Upperstructure: Control Box, 2x M pro motor for arm lifting, 1x M pro motor for 2'nd arm section and 1x M pro motor for bucket tilt. Front tire 94.3x38, rear tire 75x30,5. Model have 6 working finctions powered by 2x Cada Control Box + 3x L Pro Motor, + Pro Servo Motor + 3x micromotors. Of course set have header trailer. As you can see, the sets have a lot of electronics. Don't expect prices of $150-200 ;)

New inside flat Link Treads and a large Z104 bearing turntable in the JCB excavator that I designed together with @SaperPL

Unfortunately I cannot confirm this. The CADA remote control does not have proportional control. Also in the CADA application there is no profile that use the servo motor.

Well, the JCB excavator was already visible in the previous catalogue. Unfortunately, at the final stage we have to solve a few problems to make the set perfect. Now that it's official, I can show next model for CADA, the CLAAS Dominator 370 combine harvester. It will be a real flagship! Also congratulations to @efferman and @Bricksley for joining the CADA family of designers. Great models! :)

At first I noticed that the telehandler is very massive but when I realized it RC in this scale it blow my mind. What a fantastic, compact and detailed model!

Fantastic details for this scale! I especially like how the rear lamps look, so characteristic of this car :)

And it will be, but not from TLG :) They are not needed. It all depends on the type of the combine. A smaller machine on a scale of 1:17 have tire diameters of up to 94 and 75 mm and will correspond to real dimensions.

First: Lego don't have a JCB license :)

Last week, the model before final production. I've already had one test before. I corrected two things that I wasn't satisfied with in the final version. I really focus on making sure the set is flawless and works perfectly. Especially since JCB is very demanding and we are now waiting for their final approval. I know it takes a long time but I assure you it is worth the wait.

I don't have a specific date, but in the first half of 2024 there will be a real gamechanger when it comes to agricultural sets made of bricks. It will be a real flagship with over 4,000 bricks and a license from a large agricultural company. The tractor is planned, but we will discuss the details next year. It probably won't be CASE Quadtrac. There are a lot of great MOCs and we would like something new. Stay tuned ;)

@imurvai Is it possible to display information about the voltage of the device(s) on the screen when using the profile? This information is displayed in the application after connecting the device separately. This makes it easier to control the battery charge level. :)

240$ is good Price for this masterpiece.

This solution takes up far too much space and still does not solve the basic problem - lack of precision. We're not getting off topic. That's a conversation for another topic.

Lego pneumatics sucks. Don't even try to change my mind :D

I think it looks very good. I look forward to further progress :)

It's amazing how beautiful a model can be built from bricks. It's incredibly realistic. The liebherr color scheme works in plus here. The white cabin makes the model much more pretty than the completely yellow machines. It works very well and that's about it. Congrats!

Unfortunately, our friend does not understand this. He picks up only those elements of posts that are easy for him to relate to.
