This Combine/Harvester is a top to bottom demonstration of wonder of mechanics! When Harvester is moving forward, the reel starts spinning as in the real thing. The model has a built-in secret box which opens with a lever located to the left of the driver’s cabin.
Harvester's rubber band engine is wind up by simply dragging the model backwards or spinning of the large back wheel. On the other side of the cabin there is a ‘handbrake’ lever that can lock the vehicle in place.
