The UGEARS Combine Harvester is a truely magnificent model that demonstrates the wonder of mechanics. When it starts moving, the Combine’s reel starts spinning as well – like it would on the real thing! The Combine Harvester model comes with a secret built-in box that conceals a lever to the left of the driver’s cabin. To get your Combine harvesting, simply drag it backwards to wind up the rubber-band engine, and release. The engine can also be wound up by spinning the large back wheel. To the right side of the driver’s cabin is a handbrake lever which stops the Harvester from moving. Wind up your Harvester and release the lever for an unconventional drag race!
