The author remixed this model.
The tractor is great, but I decided to improve some parts and designed additional parts as well. The file format is STEP instead of STL because of better print quality. Prusa Slicer can handle it as well.
Everything except the tires (TPU) was printed in ESUN PLA+
The tractor itself is the same, but some parts according to the pictures are my own design:

The ESP32 Arduino Sound & Light Controller & ESC are my own creation and can be found here:

The driver figure is based on a a free model from https://renderpeople.com/free-3d-people/ and not my own work. It was just adapted to the shape of the tractor, using blender
