Abstract: A harvesting apparatus includes a crop conditioning element coupled to a frame, and a hood moveable relative to the crop conditioning element. An actuating system moveably connects the hood to the frame. The actuating system includes a driven lever arm rotatably attached to the frame and including a first lever connection and a second lever connection positioned opposite each other across a lever rotation axis. A first pivot assembly is rotatably attached to the frame and includes a first pivot connection coupled to the first lever connection of the driven lever arm, and a second pivot connection coupled to a first lift connection of the hood. A second pivot assembly is rotatably attached to the frame and includes a third pivot connection coupled to the second lever connection of the driven lever arm, and a fourth pivot connection coupled to a second lift connection of the hood.
