A wind turbine includes a tower member a yaw system, and a wind energy collection system. The wind energy collection system includes a central hub and a plurality of blade members. The wind turbine further includes a component manipulating system operatively coupled between at least one of the plurality of blade members and the tower member. The component manipulating system includes a blade member support structure including a first end pivotally connected relative to the tower member that extends to a second end operatively coupled to the one of the plurality of blade members, and a winching system operatively connected to the one of the plurality of blade members and the tower member. The winching system is selectively operated to shift the one of the plurality of blade members relative to the tower member in order to enable serving of the wind turbine.
