Ugears Combine

This is one of our more advanced models. The model is inspired by a grain mower. The combine has a threshing drum that rotates when the combine is moving.
 
On the roof of the combine is a secret room where you can transport small items. The lever on the left opens a secret compartment and the lever on the right turns the engine on and off. You wind the model and after turning the lever it goes to work.
