[MOC]Falconluan's technic tractor MOC series: RC Case Magnum Rowtrac

[falconluan]

#2 CLAAS Axion Terra Trac

As its real world counter part, it is easily modified from a normal wheeled Axion 900 . The modified area is rear axle, central area and rear fender(the track is longer while lower than wheel, so the tank is moved from center to the rear fender position) .

Features:

• Pivoted solid front axle
• Pivoted rear track
• HOG steering
• Adjustable front hitch
• Adjustable rear hitch
• Rear PTO connected directly with rear differential
• Modular design: chassis, rear hitch, cabin are built separately

Instructions on RB:

Thanks for watching!

Nice variant! I've bought the instructions for the wheeled version and planning to build it with some little mods.

Thanks for your support! Please let me know your feedback on the model and its instructions. Also it will be nice if you can share your mods here once done

I've built my own version starting from your instructions: it was scaled down to 1:21 scale to fit my other mocs (Mack scale). I like it a lot, thanks for your input!

In the model there are 4 not-Lego parts (rear wheels), because TLG doesn't produce them in the right colour.

Great update @mpj to a great tractor by @falconluan. It's a shame those rear wheels don't come in red. Maybe someday.....

Glad you like it and it looks cute in smaller scale!

Am 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]

Hi 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.

There are white rims also if you know 

They are cute

Thank 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.

Yup, the Blue Power version is indeed coloured dark blue & silver whereas ordinary models are blue & white.

I have to agree it looks absolutely great! (though it would be even better with rear tractor tyres in the right size...)

It would be nice to see more tractors (and other agricultural equipment) in such scale. Haven't you thought of some kind of attachment?

Thanks @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

Yeah it does!

You bet, I'm always happy to see the Thirdwigg Farm expand. There is plenty of work to be done, so keep the tractors coming.

Thanks again mate!

As to keeping more tractors coming, a preview of the finished Steyr Terrus

Love the New Holland and the Steyr!
Now missing a John Deere and a Fendt

yes! And @falconluan could also update the Claas!

Yes! 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

Hi 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.

After 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!

To use 4wd with 81 mm at front and 107mm rear, you have to use 12 to 28 tooth at front differential (as you made) but use 20 to 28 tooth at rear because rear tire has bigger rolling circumference (front 81mm × 3.14, rear 107 x 3.14)

It 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 .

[1gor]

Probably your colir combination blinded me; another thing - this chasdis will be a tail dragger or sled...tractors have a bit raized rear part and rear axle should be just one stud higher (107 - 81 = 26; 26 / 2 = 13 mm which is 1.625 studs -> 13 / 8)

[Jundis]

Very cool you started a tractor with this wheel combination :-)

From my first attempts for a John Deere 8R, I use a height difference of 1.5 studs. It's a little bit unconvenient to build, but looks better than the 2 stud height difference, IMHO.

Thank 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...
