Connect the swivel adapter to the end of the steel pole then bolt the wind turbine to the top of the adapter. The turbine should rotate freely around the steel pole.
Drill a 3/4-inch hole in the side of the pole at 8 feet 4 inches from the open end.
Feed the wires from the turbine down through the center of the steel pole and out of the hole you drilled in the side. You may need pliers to pull the wires out the hole initially.
Dig an 8-foot-deep hole using the post-hole digger. The hole will need to be about 2 feet square at the bottom.
Mix 10 pounds of concrete and the corresponding amount of water, as stated on the concrete package, in the wheel barrow using the shovel until the concrete is a consistent mixture.
Pour the concrete into the bottom of the hole and then insert the steel pole into the center of the hole, down into the concrete. Use the level to make sure the pole is perfectly vertical.
Bury the concrete with the dirt you dug out of the hole until it is about 6 inches from full.
Mix up the last 10 pounds of concrete and pour it onto the top of the hole. This will form a strong base to keep the pole upright.
