On the 30th of September 1971, my father bought his first tractor.
On its 45th anniversary, I proudly presented my next 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!
Important update 2019
There are a few important changes for this 2019 version. Please check updated BOM spreadsheet with new parts and links.
List of improvements:
- 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
- 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.
I shared a spreadsheet with all parts and updated links to buy components that you can find here: OpenRC Tractor BOM
Please, check the BOM spreadsheet because there are some original parts that you won't need.
The tractor is designed to be easy to print and no supports are needed for any part.
If you have any question, please check FAQ section where you can find updated information about assembly and some tips on choosing components. YOU'LL ALSO FIND LINKS TO NECESSARY COMPONENTS.
Before asking, please watch my new assembly videos: Build with me videos
Points to bear in mind:
As part of optional parts, you'll find different optional plates. There is one for Spain and one for Sweden because there are already OpenRC tractors in both countries. If you print your tractor and you would like to have a plate with your country letters, write a comment and I will try to add it.
Original recommended motors have poor torque. They work on smooth surfaces but not off-road. I strongly suggest you use 2019 version with differential gear and a motor with more torque.
