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
I redesigned some parts of the tractor to improve the riding. Now it features a differential gear, improved rear tyres and I designed new optional rear tyres for smooth surfaces. You can check updated BOM spreadsheet with new parts and links. Moreover, I'm preparing a video tutorial of assembly and connections that I will add gradually.
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.
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.
I used same bearings as OpenRC F1 to make it easier for those who already have the F1.
