Windmills are set up by using a Windmill Kit on Pit Stakes. After five minutes, the windmill will become a Windy Windmill. When it becomes windy, players can use it to turn Bucket of Grapes into Bucket of Grape Juice and Sacks of Wheat into Sacks of Flour. After two more minutes, the windmills will stop being windy. They can also be cut down with axes to leave a Windmill Kit.
