The UGEARS Combine Harvester is a top-to-bottom example of the wonders of mechanics. Drag the harvester backwards to wind up its rubber band motor. Release the hand brake lever and off you go to bring in the crops. You'll see the cutter board reel at the front spin just like a real harvester, but what you won't see is a hidden box to the left of the driver's cabin for sending love notes to your favourite farmer.

• Moves slowly with a help of rubber motor.
  
• You can open a secret box using the special lever.
  
• No glue or any hand tools needed for model assembly – the parts are ready-made and can be simply removed from the board and assembled together.
