This authenticated and licensed John Deere windmill comes with a 10 foot tower and 27” fan blade face. Completed it stands 12’ tall. This windmill is crafted from the finest quality steel and coated with UV protected powder to ensure that it will last for years to come. Some assembly is required and a 7/16” and ½” wrenches are required. Ground rods are included and it is recommended that you concrete them into the ground for more stability in strong winds. A separate aeration kit (OWS-BY0007) can also be purchased to convert the ornamental windmill to a functional aeration system for a small backyard pond.
