On the 30th of September 1971, my father bought his first tractor. On its 45th anniversary, I proudly presented my star project, the OpenRC tractor.
It's an open source 1/10 scale replica of an original Ebro 160D tractor. I designed it all from scratch and 3D printed all parts. Then, I added some electronics, nuts and bolts and I made it work!
Since I released the first version, I never stopped designing new tools, mods and improving my original design. Here in my site you'll find links to materials, stl files, tutorials and, everything you need to build your own tractor.
Versions of the tractor
OpenRC Tractor MK1
Download MK1
This is the first version of the tractor. It was released in 2017, on the 45th annyversary of the actual real tractor.
This version is functional but it has been greatly improved. There is a motor mod for this version (allows 540 size motor) but I don't recommend it as the tractor becomes uncontrollable.
If you're printing the tractor for the first time, you should always print last version of the tractor.
OpenRC Tractor MK2
Download MK2
This version was released in 2019 and improves several things:
- I redesigned the transmission so you can add a differential gear. That makes the riding much better.
- I used a new motor that has much more torque.
- I designed new rear tires for smooth surfaces.
- New under motor channel for rear cables.
- I redesigned original tires to reduce vibration on smooth surfaces.
- New series of assembly videos on youtube: Build with me videos
- New updated spreadsheet with materials and links.
I tried to modify as few parts as possible, but you'd have to print some new parts. Please, check the BOM spreadsheet because there are some original parts that you won't need.
OpenRC Tractor MK2.1
Download MK2 tractor
Download differential mod
Download MF 65 mod
In 2020 I added a differential mod that helps with diff problems. They are just 3 new pieces but it makes a big difference.
You'll need OpenRC tractor MK2 and differential mod.
I also added MF65 mod parts. You can print original looks or MF65 mod but, if you print original, I suggest you print tires from MF65 mod (parts 28Am and 28Bm), they are much better looking (in my opinion).

I spent almost two years working on it. It has been completely designed from scratch and has many improvements over the previous versions:
- Dual motors
- Much more detail and realism
- Much easier cable management
- No differential (forget grinding problems)
- Ackerman style steering
- Standard servo steering (micro servo optional)
- 3 part rims (beadlock style), so tires can be printed in any filament, flexible or not.
You can already check list of materials and printed parts
Instructions
There are different tractor versions (see below). It's always strongly recommended to print the last one, as it is always the better improved one.
I shared a spreadsheet with all parts and updated links to buy components that you can find here: OpenRC Tractor BOM
The tractor is designed to be easy to print and generally you won't need supports except for some few parts.
If you have any question, please check FAQ section where you can find updated information about assembly and some tips on choosing components.
