falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingWow, that is a very informative comment, thank you @Jandel47 You are correct, the diecast model is a 7480. And because of that I was planning to build a 6480/7480 at the beginning, yet to find the 6-cy engine is quite a challenge. Even I get rid of the small turnable to allow the steering rack moved further back, there is no easy way to have a 6 pin thin beam setup easily for the engine. If use a normal beam instead, it means more height(5L) and the available height under the front part of hood is 4L... Based on my very inaccurate measure, the ideal wheelbase is between 19 and 20L, current setup is 20L, I can shorten it after the central structure is finished and it stills looks too long. Then I'll keep the wide fender and consider it a 64/7480 with wide tires -
falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHi @Jandel47, thank you for your offer for help , also if you don't mind, please feel free to point out the places of it you think needs to be improved. That's a very detailed info which I didn't know before. I knew that that are two different looks of the hood of the 6400/7400 tractors, and I'm planning to build the newer version. A quick google search told me that there are other difference between them like engine, suspension, etc. Basically, my target is the die-cast model like below: Currently, I'm working on the rear fenders, and I made two versions, a wide one and a narrow one, the I checked the "Farmer Phil" YT channel where he has a wide tyre 6499, the red potion of rear fender does cover almost all the width of tyre. So I think the wider version is better, although it has a down side of more red 3# connectors are needed. What do you think? Thanks @1gor for your suggestion. Here is a closer look of the hub support structure. Due to the space for pivoting, the space above the 1L beam(between 6536 and 41677) needs to be not occupied. So if a T shape beam put there, only its end tip pin hole is available to be used which is not very stable as well.

falconluan replied to Jundis's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingMy topic is this one I've managed to make an axle connection avail place at the wheel hub steering link connection point, it may not be ideal but it is the best I can do at the moment.
-
falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingThe chassis is somewhat finished, there is very limited space since a realistic scaled chassis width is 5L. Also since it is now a 4 cylinder engine, I think I'm now building a 6400 series

falconluan replied to Jundis's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingA very interesting machine you've picked. Looks like the axle with black simple fenders(hard to tell it's front or rear) are not swingable in your model, not sure if it can in the real machine. Currently I'm struggling building the front fenders on my tractor. Only have very limited space around the wheel hub...

falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingThank you for offering help and you've already helped me As to broken parts, I will definitely ask you for more help when I want to power my tractors

falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingIf you meant that you derailed my moc introduction topic then you did not at all. The discussion above is very informative and I enjoyed reading them very much. I've read and watched the drivetrain pics and videos like you pasted as well and found it very hard to replicate with lego, at least for me to do so ... So I set my minimum goal of my first bigger tractor moc as a directly enlarged moc of my smaller one, I take any function beyond that as a bonus. Then I will try to improve the chassis with following iterations and mocs gradually.

falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingSome update The height diff between front and rear axle is now reduced to 1 stud as @1gor and @Jundis suggested. Other change includes steering link moved to the backend of axle, making some room for the fake engine. Lot of places still need to be further reinforced.
-
falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingThat's a good idea Interesting that I planned to make a suspended axle in next MOC as part of iteration process . Another solution I can think of is accepting the 1 stud height difference. Use 20 to 16 gear pair followed by 16 to 16 gear pair to achieve 1 stud height diff. By doing so will create a 5mm higher sitting rear axle than front and it may look better than a higher front anyway.
-
falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingThank you guys for the height suggestion 1.5 studs diff seems to be a hard thing to achieve based on my current setup, no universal connector in the drivetrain. Any further suggestion? I'll think about it as well...
-
falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingIt is probably not clear enough in the photos, I used a pair of 20 to 12 gears at the central diff front axle output to overcome the wheel speed difference .

falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingAfter some break, I started my larger scale tractor moc series. By saying larger scale, I mean using 81mm front tyre and 107mm back tyre. Even at this scale, the available internal space is rather limited, so I started from a full manual moc and maybe would add some electric and/or pneumatic functions to following mocs. Managed to build a proto chassis and this is what I've got so far: I'm trying to replica real tractor drivetrain layout like below as best as I can. Now it has: Four wheel drive with central diff and accelerated front axle Front and back PTO connected directly to engine(I know there is no engine yet) Pivoting front axle As to the target tractor model, I chose the MF 6400/7400 this time, hope you like it. As always, any suggestions, ideas, comments are welcomed!

falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHi everyone, I've finished the forth one of the series: Steyr Terrus Features: Pivotable solid front axle HOG steering Adjustable front hitch Adjustable rear hitch Rear PTO connected directly with rear differential Detailed interior and decorations Modular design: chassis, rear hitch, cabin are built separately Just like it's real world counter part, Steyr Terrus and New Holland T7 are basically siblings, so the cabin, fenders and chassis of this tractor are same as my New Holland T7. The hood is newly designed. Scale-wise, this MOC is larger than a 1:32 model as it shows in pics. Instruction at RB is here More pics are at here Hope you like it. Now I'm working on their other real world sibling: Case IH Optum, stay tuned if you are interested.
-
falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingYes! and also Case IH, Massey Furguson and Deutz, these many brands are either a good thing or bad thing Will definately update the instruction once I've done the Steyr, only with virtual build now since I've not got my hands on those red wheels yet
-
falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingThanks again mate! As to keeping more tractors coming, a preview of the finished Steyr Terrus

falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingThanks @MP LEGO Technic creations and finger crossed that TLG would release some 72mm tractor tires someday... Currently no, but I'm thinking of making some trailed fertilizer spreader or baler. It works well with @Thirdwigg's great looking dump trailer like below: The trailer is free and you can get the trailer in RB here. Thanks @Thirdwigg and hope you don't mind my reference

falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingThank you To be honest at first I chose 8284 because I wanted to reuse the chassis of my other small tractor MOCs. As the building went on, I altered the path to trying to reproduce the original set as much as possible. Glad that you and maybe other guys weigh the structure similarity as a plus feature of this contest. Despite the final result model is almost "useless" for my following tractor MOCs(the proportion is way off to modern tractors, even tractors of 80's and 90's), I did have lots of fun during building it, it's a great contest without any doubt!

falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingThank you! I think the white rims usually come together with "normal" versions of New Holland which are painted blue, I could be wrong here though. And pity that we don't have 7L soft axle in blue and that's why I'm using dark blue and LBG combination here. I'll use the white rims in my Steyr MOC of course.

falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHi everyone, Finally I've finished the third one of the series: New holland T7 Heavy Duty Features: Pivotable solid front axle HOG steering Adjustable front hitch Adjustable rear hitch Rear PTO connected directly with rear differential Detailed interior and decorations Modular design: chassis, rear hitch, cabin are built separately The hood and chassis are based on my Claas Axion with some improvements and reinforcements. The cabin and fenders are all newly designed. Comparing with Axion, the rear fenders are mounted half stud higher thus completely eliminated the possibility of touching the rear tires. Scale-wise, this MOC is larger than a 1:32 model as it shows in the comparison pics. Instruction at RB is here More pics are at here Hope you like it. Now I'm working on its real world siblings: Steyr Terrus and Case IH Optum, stay tuned if you are interested.

falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingSorry for misleading you about this, I was trying to say the bigger scale stuff will be my next project.
-
falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling@1gor It took some time from me building the Steyr's hood and I'm still not pleased with it now .... The whole thing is based on my Claas Axion instead of the mini 8284 here, since the proportion of 8284's chassis is quite different from modern tractors'. I've also updated the progress in my other thread, let's discuss more on it here if you are interested
-
falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingAm building some new tractors now. This time I chose New Holland T7 and Steyr Terrus, and maybe include Case IH Optum in the end as well, since they are more all less the same tractor The chassis is largely based on my Claas Axion with some improvements while the cabin, hood, fenders are newly designed. Took a dozen of iterations on the Steyr hood and still not pleased with it, so any suggestion is very welcomed.

falconluan replied to falconluan's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingAfter making the Claas Axion, New Holland T7 and Steyr Terrus(The latter two will be published soon ), enlighten by this shrink contest, I will try to "enlarge" those small MOCs into bigger ones. Will use 81mm front and 107mm back tires for sure, but not sure about the function setup yet. I think I will build a chassis mock up first and decide the next move based on that. Since even with the max available tractor tire set, the space in chassis will still be very limited, which means not many things can fit in if I want to still achieve the realistic look of everything.
