Description
This is a fully 3D printed RC tractor featuring 4WD and, even more exciting, a servo-shifted HI-LO transmission. That means you can cruise around in high gear, then shift into low whenever you need extra torque to climb, pull, or power through rough terrain.
While it may be an “RC” model, it’s really closer to a high school or college robotics project. The goal is not only to build something fun, but also to learn a bit about electronics, mechanics, and coding along the way.
The 3D files are provided completely free so you can decide if it’s a project you’d enjoy building. If you do, the Professor Boots Workshop is linked below and includes step-by-step instructions for turning it into a fully functional RC tractor. Supporting the workshop helps fund future projects like this, so thank you to everyone who builds one!
