Szilard Gyalay from the USA build our GBC 51 Gravel Works from the LEGO 42131 CAT D11 Bulldozer set.
We couldn’t be more fond of his review. This is what Szilard had to say:
GBC 51 Gravel Works - 42131 Building Instructions
Szilard Gyalay - October 2, 2023
I believe it is one of the best builds yet, with very stable lift mechanism simple conveyer belt and great use of gravitational forces for the „tilt-drop“ . The wave mechanism needs some tune-up but works well after. Dismantle and build about 8 -10 hours , Worked in the evening. I actually dismantled my CAT11 to build this.
