  1. It might seem that the field of agriculture is not much affected by the boom of modern technologies, but it is precisely in agriculture that a rapid development of automation and robotization is expected not only in the processing of crops, but also in their cultivation. For this reason I have decided to build something different this time - namely an official autonomous concept of a John Deere tractor called SESAM 2. This one differs from other visions in particular by the possibility of attaching the driver's cabin and the ability to work both in a purely autonomous mode or be remotely/directly controlled from its cabin. In the field, the cab can be detached at the headland, allowing the operator to monitor and possibly control the tractor. The efficiency is further increased by the ability to work in a swarm, so it is possible to monitor or control several machines working in the same field from one cabin. Since the real tractor has a power of 500kW, I decided not to use just one motor to drive it, but two. In terms of shape, the so-called large angular motor is suitable for the model of this particular tractor, because it enables better use of space - i.e. the possibility of placing it vertically on both sides of the chassis between the axles, thereby freeing up space in the center of the model, which can subsequently be used for other functions. A central differential is usually used to compensate for the difference in wheel speeds of the front and rear axles due to their different diameters, however the disadvantage of this variant is that if one of the wheels of the front axle is not in contact with the ground, all the power of the drive system will go to this wheel and the model will stop. By inserting suitable gears, the speed difference will be equalized, so it is possible to replace the central differential with a fixed connection of the drive shafts of both axles. Thanks to the drive motors located on the sides of the central frame, it is possible to add a mechanical locking rear differential working on the basis of a centrifugal regulator in conjunction with another differential used to compare the revolutions of individual wheels (note: each of the output shafts of the drive differential is connected to the output shafts of the "control differential", but one of them utilizes higher number of gear wheels, so when both shafts of the drive differential are at the same speed, the "control differential" does not move) of the rear axle - if the difference in the speed of the two wheels is too high, this differential connected to the centrifugal regulator also turns, with a higher centrifugal force with the arms of this regulator will begin to lift until they are far enough away from each other that the surrounding parts prevent them from further moving away, thereby blocking the entire regulator. This will stop the "control rear differential" from rotating and close the drive differential. CREDIT goes to @JoKo, I just loved his brilliant idea so much that I decided to build a model around it My original design of steering included a gear rack, but it turned out to be inaccurate in practice, and the range of the wheels was greatly limited. Therefore, it was necessary to come up with a new concept - control of the steering connecting rod using a small LA. This solution is features in particular a higher force for controlling the wheels with a reduced engine load, greater steering angle, improved accuracy and protection of the motor in extreme positions thanks to the internal safety element of the used LA. In addition, the entire axle is pendular to achieve better offroad ability. The only pneumatic circuit uses a classic pump+switch combo: A Medium angular motor is used for the rear PTO. Since a variety of implements can be attached to the tractor and there is no space left to build in any speed gearbox I have decided to use not one, but two coupled PTO outputs, which differ from each other in their speeds. The front hydraulics is driven by another Medium angular motor, and sufficient load capacity is ensured by a worm gear. Similar to the front three-point hitch, the rear hydraulics use a worm gear, with the Angular motor replaced by a more powerful Control+ L motor, as heavier equipment is attached to the rear. When talking about lighting - John Deere is based in the US, where red turn signals are common, so it is possible to use the same LEDs for both tail lights and turn signals. Blinking is solved by software changing the intensity, where the direction lights flash in short time intervals with 100% intensity, while the rear lights only shine at half power. A small addition are two glow-in-the-dark stripes on both sides of the machine, which do not require any electric connection. All "autonomous" features are in fact a mere Mindstorms distance sensor. Schematic layout of mechanical functions: Schematic layout of the mechanical functions, including the respective motors (both HUBs are located above the front axle, due to which it is heavily loaded and, together with the powerful drive system, ensure exceptional traction capabilities): Complete tractor chassis: At first glance, it might seem that the shape of the selected tractor is simpler than that of classic tractors, but upon closer observation it becomes clear that even apparently flat surfaces are curved, slanted or otherwise modified. Designing the model is also greatly hampered by the lack of visual material. All searchable photos are just a snapshot of a certain part of a not-so-long video. This video, along with the minimal amount of information published, is the only source from which the LEGO model was designed. The chassis of the production 6R series tractor gave a slight idea of the dimensions, but the body design was purely based on my own experience. Since the cabin will often stand on the ground, I came up with the idea of equipping it with rubber pads, which not only dampen the impact when it is placed, but also provide it with better stability even on uneven surfaces due to higher friction. The interior is equipped with small details, such as an adjustable steering wheel collumn and armrest or a lockable storage space under the folding passenger seat. Various devices can of course be attached to this tractor - here is, for example, Rolland Rollspeed 7136 trailer: To the controlling app - on a mobile device (tablet) the Mindstorms application will be directly connected to one of two HUBs in the model, which will directly control the motors connected to this HUB, while on the other HUB a stored program will be run waiting for the start signals that will be forwarded to it from tablet through the first HUB and their mutual (HUB-to-HUB) communication. And for more convenient control, I also used the Sony Dualshock 4 game controller. Program streamed to HUB 1: 1) Control of rear and direction lights 2) Front axle steering 3) Sending a signal for HUB 2 - turning on the front lights with the brightness value "light brightness" (14) 4) Setting the value of the "sensor" variable needed for its activation/deactivation 5) Forward/backward control along with obstacle detection and emergency stop (15) 6) Sending a signal for HUB 2 – starting the PTO in one way 7) Sending a signal for HUB 2 – starting the PTO in the other way 8) Sending a signal for HUB 2 – starting the pump in one way 9) Sending a signal for HUB 2 – starting the pump in the other way 10) Sending a signal for HUB 2 - lowering the front three-point hitch 11) Sending a signal for HUB 2 – raising the front three-point hitch 12) Sending a signal for HUB 2 - lowering the rear three-point hitch 13) Sending a signal for HUB 2 – raising the rear three-point hitch 14) Setting the value of the "brightness of the lights" variable needed to turn them on/off 15) Setting the value of the "stop" variable for turning on/off the emergency brake Program stored in HUB 2: 1) Signal reception from HUB 1 – turning on/off the front lights 2) Signal reception from HUB 1 – lowering/raising the front three-point hitch 3) Signal reception from HUB 1 – lowering/raising the rear three-point hitch 4) Receiving a signal from HUB 1 – starting the PTO in one or the other direction 5) Receiving a signal from HUB 1 – starting the pump in one direction or the other Some dimensions: Length (without cab/with cab): 360mm/445mm Width (without cabin/with cabin): 180 mm/225 mm Height (without antennas/with antennas): 184 mm/218 mm Wheelbase: 160 mm Wheel track (front/rear axle): 136 mm/136 mm Weight: 2660 g (Without cabin); 3035 g (With cabin) Proportional axle load: Front - 55%; rear - 45% Load capacity of three-point hitches: Front - 626 g; Rear - 565 g (well, that's definitely interesting ) The model consists of a total of 2950 original parts, while I managed to build in the following features: • all-wheel drive (2x Large Angular motor) • automatic rear differential lock • front axle steering (1x C+ L motor) • swinging front axle • front three-point hitch (1x Medium Angular motor) • rear three-point hitch (1x C+ L motor) • auxiliary drive of implements (1x Medium Angular motor) • pneumatic drive of external devices (1x C+ L motor) • front and rear lighting (4 pairs of LED lights) • obstacle detection and automatic braking systém (Distance sensor) • remotely detachable cab with movable interior details • robust bodywork with easy access to control units Link to WIP topic: I hope this post has not somehow exceeded the maximum allowed length or anything like that Thanks for visiting & comments are welcome!
  2. Hello guys, few days ago i finished and released my latest MOC. And here i want to share it with you and it a bit more technical aspect of it. if you are interested. (My english may have few errors) Main one is the tractor, as you can see its Case QuadTrac 620 articulated tractor, aimed for 1:17 to match with trucks and other farm machinery, mainly eric´s if there is collector who appreciate that. but this scale is also big enought to pack everything needed and look good, and small enough for not needing large uniform boring surfaces. On the outside it may look like pure system thing, but on the inside its packs 6 PF motors. two of which are L motors for drive, 3x M motors, two for sariel.pl pneu/switch combo (two independend systems) and third is in the rear of the body for PTO output. and last is standard servo which uses opposide steering rack system for quick response in oposite of standard linear acctuators, this system is in my opinion even more compact, reliable and more enjoyable to play with. However if exposed to very large resistance it may throw timing off. (i dont recomend steering while stationary on carpet or floor). Secondary features are : Connected steering wheel to the servo system while the cabin itself has suspension. Driver seat is rotatable to the right side as the original. left staircase swings away from the path of tracks while being steered to the left. and full suspension on all 4 tracks and also rotating rear section for compenstate for uneaven surfaces. Everything is powered by 2x buwizz 2.0 bricks. It may seems like an overkill for instructions but i chose to not make too much compromises. i wante model that can do it all, exept it cant lift things because its lack of three point hitch. About the trailer. Its mostly System bricks and creator style creation with minimum of technic features so i will not talk much about it, but it has three functions. first is PTO input which powers conveyor on the floor of the bin and it also diverts into auger conveyor to spin worm gear at the end to look like there is actual function to it. However it cant move real stuff. Second function is pneumatic support leg at the bottom, so after attaching it to the tractor with pin and connecting all the hoses. you can remotely operate entire trailer. Third feature is extending auger conveyor to simulate real operation of this kind of machine. I am aware of few off-scale bug on this model. main one is taller track system due to including suspension. and shorter trailer bin. If you are interested in instructions they are on my RB profile: https://rebrickable.com/users/Klein.Creations/mocs/ There is one independent video review and one video of my own. i hope you will appriciate and enjoy both of them.

  4. Lego Tehnincs for me started with 42000 set. First step to own creations was small B-model modification Then I started to create my own creations. At that time I didn't even knew about other "sick" peaople and forums like this. So, as a first post, littlebit about what I have created until now. First creations was only from parts of 42000. First creation was some trike (or something like this) with font wheel drive Then there was (street)quad
  5. Hello Community, I want to share a cool idea and model I came up with - using relative new 28T gears as sprockets for a tracked vehicle. When I first saw the inventory for the new 42168 John Deere 9700 Forage Harvester, I was impressed on how many gears are packed inside this small model so I decided to use as much as possible of them for a tracked Tractor. But can all that gears are used as sprockets for driving small tracks? Lets find it out. The new 28T gear fits literally perfect as sprocket and thanks to the soft tooths of that bevel gear, tracks are running surprisingly smooth. Every second tooth fits inside the gaps of the track links, where the other tooths fits inside the gaps of the track part itself and so on. With such a setup it might be possible to build a tracked vehicle and I tested alot on the tracks and the sprocket setup. Available gears from the 42168 Forage Harvester are not enough, so I decided to use the yellow gears only for the visible side of the model and to use other parts provided with the set to prevent the additional tracks from slipping... The model I ended up is a John Deere 8RX Tractor as alternate build for the 42168 John Deere Forage Harvester that requires 124 additional widely used track links (part 3873). Something odd, a model that requires additional tracks and let you the tires left over for some other cool stuff. The Tractor comes with steering and a working piston engine. Only parts from donor set 42168 are needed and all functions are working even without the additional track pieces. Lets take a look how smooth the tracks are running. The model is steered with wheel from the back (shown in blue) while the rear tracks are running the piston engine (shown in green) by driving the model smoothly over rough ground. Let the piston engine run by driving the tracks or by rotating the rear sprocket manually. Some impressions: If you like what you see and want to build your own John Deere 8RX Tractor Unit, feel free to support me on rebrickable. Happy Building.
  6. 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.

    Bamboo Cruncher 6000

    My third, and likely final Space Jam 2023 entry - this time for Bio-Mechanical Fusion. Friendly and intelligent sustainable harvest equipment Working rear "dump truck" for unloading harvested shoots Not sure if this is a "legal" technique, but the underside of brick separator handles has pretty respectable clutch power Modular (dis)-assembly is important when key parts are also toddler bath toys
  8. The project started long before the reveal of 42136 John Deere set, but I wanted to make the front steering with custom 3D printed parts initially and I got stuck on the 3-point hitch/PTO mechanisms, so it was sitting on the hard drive for few months. After figuring out how to make the 3-point hitch mechanism I realised I can make the virtual pivot steering and picked up the designs again around a week before the 42136 was revealed. The trailer however was clearly inspired and initially based on the trailer from the photo of 42136. The rotary rake uses PTO at the back which is integrated into 3-point hitch, but as there is not much room to fit a clutch anymore, the rotary rake is disconnected by folding it's sides up instead of disconnecting the PTO on the tractor's side. There is also a PTO at the front underneath the bumper, but I haven't figured out an attachment for it yet. Full gallery: https://imgur.com/a/dyCV5qL Video featuring speed builds of each part of the set and functions showcase: Instructions are coming, I just didn't make it with time as I didn't expect this project to grow this much with the implements. EDIT: Instructions for the tractor are online: https://rebrickable.com/mocs/MOC-97150 EDIT2: Instructions for rotary rake are online: https://rebrickable.com/mocs/MOC-97247 EDIT3: Instructions for the tipper trailer are online: https://rebrickable.com/mocs/MOC-97357
  9. All Thirdwigg Farm Instructions Tractor Instructions Forestry Trailer Instructions Dump Trailer Instructions Disk Harrow Instructions Mechanical Seeder Instructions Power Harrow Instructions Furrow Instructions Snow Plow Instructions Mower Instructions _______________________________________________________________________________________________________ A lot of WIPs going on here is Thirdwiggville, so while the Unimog and SRT are still in progress, let's add another tractor. The tractor came together in 10 days, which is pretty quick for me. Not sure about the mirrors or the air intake, but the rest is pretty final. Now on to the trailers.
  10. Perhaps the new theme park needs a better transport which can maneuver in the city, right? Based on my previous truck design, I did this for moving the raptors. The tractor section has a turret that can be used for any emergency cases like dinosaur escape, and now raptor transport can go through the city without problem! Hope you enjoy this :) thanks!
  11. Not shure about B model, but A should be garden tractor. B could be simple lawn mover. I'm also thinking about some dragster. Some teaser picture
  12. I know that I shouldn't start another build before finishing all those previous ones but you know, when you get an idea, you sometimes just can't resist... Well, this time it's an electric tractor - John Deere SESAM 2 (Sustainable Energy Supply for Agricultural Machinery) because I've realized that it would be useful to have something to pull a trailer full of harvested "beets" from my ROPA harvester. I've decided to build this specific one because I wanted something that no one has built before (presumably) and I find this concept quite interesting as well. The problem I've faced from the very beginning is lack of any documentation - I can only build according to the video below (and photos that are mostly from this video). All I know is that it is based on a 6R tractor and its cabin comes from some kind of a harvester. The idea si that it can work as an autonomous tractor as well as a classic tractor (well, you can attach a cabin ) I also wanted to try designing a model in digital form before ordering all those expensive green parts This is where I got: Powered by 2 Mindstorms RI Hubs 7 motors (already placed), a distance sensor at the front and 4 pairs of lights (front, rear and indicators) 4WD with central differential and automatic rear diff lock (@JoKo will know ) by 2 Large Angular motors Steering via 1 C+ L motor Rear PTO (1 Medium angular motor) Front hydraulics (1 Medium angular motor) Rear hydraulic (1 C+ L motor) Sariel's pneumatic pump with switch for power output Pendular front axle First prototype of the front grille: Cabin: The internals: I know, it's already quite crammed inside but as I've already built it IRL, I'm really satisfied with the result! Everything seems to work well, the drivetrain is efficient (thanks to batteries at the front it can easily pull heavy objects) The only thing that isn't that fantastic is the diff lock (as many of you definitely spotted even in the beginning) - it works well, however it's only useful when one of the rear wheels is lifted off the ground. I can only pray that the front pendular axle will always copy terrain and have enough traction at anytimes I hope I'll manage to make a few photos of the real thing this week. Thank you for reading & comments with any suggestions are welcome as always!
  13. Hello all, I would like to present here my latest creation - the historic Czechoslovak tractor Zetor 25K. Series K is derived from original model 25 which was manufactured in many modifications in years 1946 to 1961. Features: 2 cylinder fake engine drag link steering towing joint three-point-hitch operated from the cockpit rear PTO connected with gearbox to drive train, switchable by lever from the cockpit I also want to build some attachments to make model more playable.
  14. Another addition is added to the Thirdwigg Farm with the John Deere Scout Tractor. Built in the same scale as all the other machines, this Tractor has the same attachment points as the Atmos tractor, so all implements are interchangeable. Features: Steering Rear PTO Lifting Bucket Tilting Bucket Removable Bucket Front Implement Mount Rear Implement Mount Free Instructions for the Tractor are at Rebrickable.com. Instructions for a small trailer are also free. Instructions are also available for a front snow plow, and a rear snow blade. Find them at Rebrickable as well. The tractor makes a fun little companion to the Atmos tractor. And a little video of the tractor. Something is not working with my filming, so it's a little below my usual standards. I hope you all enjoy!
  15. This thing - called world fastest tractor. World's Fastest Tractor (jcb.com) Was considering also large scale, but stopped for a moment on some midsize. At the end it has also some functions - fake engine, differential, HOG steering, openable hood. Also on original there are not much function - mainly high speed. Disclaimer - inside pics was better then in outside somehow (maybe because of winter) Fake engine - four working cylinders, but it is six studs long, so two really fake cylinders. In fact, to be in scale, this kind of fake engine with 6 working cylinders, would fit with Volvo loader wheels. Engine is at slight angle, just like on original This is how HOG steering crosses drive axle (red) Bonnet could have been better, but there is no 9x3 curved panel or similar. I tried idea with some angled connectors, but this straight solution seemed better. Also it would been good to have those rear fenders in yellow. They are available, but I don't have them. Rebrickable showed, that average price is 30EUR, but in fact, it appeared, that they are some few euros on bricklink. By form they are almost perfect. Maybe will continue with large scale on Volvo wheels. But who knows, when that will happen.
  16. Hi guys Recently, I finished another model. It is a tractor unit inspired by Scania S-Series trucks. It has 6x4 drive and suspended axles. The front axle is suspended with normal LEGO hard shock absorbers. The rear axles have rubber suspension which imitates air-suspension as used in real trucks. The suspension at the rear axles is a bit hard but chassis is in return flat. The fifth wheel as a self-locking mechanism so that you can couple a trailer easily. To open the fifth wheel a small linear actuator is used. For steering a PU L motor sits directly on the front axle. For propulsion I used two PU XL motors. But check the pictures and video: Instruction at Rebrickable: https://rebrickable.com/mocs/MOC-86508/FT-creations/6x4-tractor-unit-inspired-by-scania/#details

    Hi, pleased to present the latest Æmiliabricks Lug work, a typical farm of our country. It required a long work and many buckets of pieces. This version is a work in progress as we still have to refine many details. Hope you all enjoy it.
  18. I present to your attention the Liebherr 984 excavator. Liebherr 984 Model weight 6.5 kilograms Model width 30 stud Chassis control two M motors with separate BB Pneumatics control three M motors and an XL motor for turning the tower as well as with B For pneumatic pumps a separate L motor with BB
  19. This is a model of a bulldozer CAT D6N the famous American manufacturer. The model is made in the style of Model Team and Lego creator expert. The inner part consists of Lego technic parts. This model uses the following system Power Functions. The chassis of the bulldozer has an active suspension like the original model. The control of the bulldozer knife is carried out in two directions. The operator's cabin is fully detailed. The model uses four motors, two L motors for turning the chassis, one M motor for lifting and lowering the knife, and a train motor is used to turn the knife.
  20. Hello everybody. I am in the process of building my own tractor. It's taken a long time, and I'm not even close to finish. One of the things I've been struggling with, is to motorize the raising and lowering of the rear hitch. I've copied/stolen the design from the 42054 Claas Xerion, so I hope someone has already done this conversion, and are willing to share how they did it. Here is a picture of the hitch design, in case you've forgotten how it is implemented in the Xerion.

  22. Hi all! It's been a while since I've posted anything here. But here you go, my little side project: Vintage Tractor Functions: Steering via steering wheel Fake L3 piston engine driven by the rear wheels via differential Moving valves synced to the pistons (more or less) Simple 2-speed gearbox controlled by a lever Rear Power-Take-Off controlled by a lever The main feature of the build are the moving intake and exhaust valves synced to the piston movements. They are driven by two cams phased 180 deg from each other. The biggest challenged was to figure out the way to move the valves for the central cylinder in the opposite way. The end solution was to link it to the opposite shaft using a 5M lift arm. See it in action in the video below. Video: The model is different from how I usually build. Since my last post more than 5 years ago I've been working on two projects, mostly in series (not in parallel). Both of them are very complex (to my taste) and move at a very slow pace inspite of huge amount of time invested in it. I am a perfectionist and while I am trying to restrict that side of me in the daily life, Lego is a way to let it go. So for two "real" projects I optimize every single module of a MOC dozens and dozens of time. And it takes forever to finish anything. That MOC here is my brake from it. It's a study into what I can get if I don't optimize too much. The idea was to accept the first solution which works. The finished result as you can see is not polished and rough around the edges. But it works. And it was completed in a fraction of a time needed for my serious MOC of mine. And I am happy with it. As for some other people, the inspiration came from the beautiful 4000025. At about the same time I saw an Allis Chalmer Model B displayed as a decoration at my local grocery store. And I felt in love with that thing. It's one of the most elegant piston-driven vehicles I saw IRL. Four cylinders, gearbox, torque tube, differential, and portal axles. What else do you need? So I've settled to re-create it in Technic with the following objectives: Do it quickly; Try to accept the first solution which works Function-over-looks Make it true Technic without much system parts Try to implement all the main functions in a small scale Make everything work reliably So in the end I wasn't able to build the Model B. It ended up as a generic tractor looking nothing like my inspiration. Which is fine, since function-over-looks was one of the objectives. With the release of this part I am now eager to build a true replica of the Model B. But, that a next step... I send my greetings to the talented builders who posted some truly incredible vintage tractors here recently: 4000025-Inspired Ferguson TE20 Tractor by @Brickend Vintage Tractor by @MangaNOID Old Little Tractor Lanz Bulldog by @Jundis To finish it off here are some additional photos. I am lucky to live in Southern Ontario, where farms are breathtakingly beautiful Criticism is welcomed! And stay tuned for a proper MOC. Hopefully won't be long. It is sitting on the shelf waiting for the video and some additional photos.
  23. Some time ago I started building John Deere 8RX model in 1:17 scale. Unfortunately, due to the difficulty of the model, the scope of the work is very slow. The project assumes rear and front three-point linkage, rear PTO driven by 2-3 m motors, one pneumatic output, 4x4 drive - XL or L motors ( if I have enough space), steering with servo motor, everything controlled by 2 sbricks. One of the biggest problems with this model that I encountered at the very beginning of the project was the drive of the tracks and the exact representation of all its moving elements. The second problem is the 8RX mask and its curvature. This is my 3rd mask concept. Now I'm waiting for the green bricks to finish the prototype of the mask. And move on to body design .

  25. Hi everybody, I'm newbie to the EB, so I'd like to introduce myself with this humble MOC. I'm a fan of LEGO Technic and pneumatics, especially RC ones. I hope I will meet here more fans of LEGO Technic pneumatics. I'd really appreciate any discussion and suggestions. Features: Powered and controlled by BuWizz 2.0 + 2 x Sbrick + PS4 controller + BrickController 2, 16 RC functions (12 can be used at once); 7 x PF motors - 4 x servo motors and 3 x L motors 6 x PF LED RC AWD powered by a PF L motor - with a central differential and gearing including the difference in the wheels’ diameters; pendular driven front axle controlled by PF servo motor - the pivot point is above the wheels’ axle to limit overlapping wheels on the front loader - like in a real tractor; differentials on both axles; 7 RC pneumatic functions controlled by 3 PF servo motors - 3 of them can be used simultaneously (selected manually). 3 at the front to serve the front loader, 4 at the back - one for 3-point hitch, and 3 outputs for additional attachments; pneumatic pump powered by a PF L motor and connected with all RC controlled pneumatic valves. It works proportionally to the opening of the pneumatic valves what ensures smooth work of pneumatic functions. Front loader with 4 attachments - brush grapple, wrapped bale grab, pneumatic sliding pallet forks and bucket; PTO shaft - powered by a PF L motor; trailer hitch; opening hood and doors; lights - front and rear, roof spotlight, blinkers, beacon lights; simple interior - steering wheel and driver seat; Here you can see it in action:
