A new OpenRC tractor tool is out, the fertilizer!!
You'll need a micro motor Link
I recommend more than 100rpm for this use. Moreover, you'll need some M3 screws and nuts. I connected it with the tractor ESC so it runs accordingly. In fact, in old tractors as this one, it used to work like this.
Hope you like it! ;)
With OpenRC tractor, possibilities are endless, new tools keep coming...so stay tuned!! (see below updates and get more details at (http://www.makitpro.com)
