Hydrator is used to hydrate tilled land. It is useless without a Basic Farmer or Galgadorian Farmer. Hydrator requires a tank with water installed in the cart. Old version of Hydrator requires water buckets to be placed into its slot (via cart's GUI).
The tilled land will be hydrated according to the tool installed: 3x3 square if Hydrator is used with Basic Farmer, 5x5 - if used with Galgadorian Farmer.
