With more than 550+ pages of building instructions and many hours of building fun this new GBC 51 Gravel works is a true master build.
Created entirely from the LEGO 42131 CAT D11 Bulldozer set we re-used almost every part to make this machine become reality. It took months to complete and we are happy to share with you that you can now build it yourself via our building instructions. You can power it via our USB Power Box optionally to save on batteries. The GBC Funnels are also optional parts which can simply be clicked into place.
