Mower conditioner impeller hood actuating mechanism

A harvesting apparatus for an agricultural machine, the harvesting apparatus comprising:

• a frame;
• a cutting mechanism coupled to the frame and operable to cut crop material;
• a crop conditioning element coupled to the frame;
• a hood moveable relative to the crop conditioning element, the hood including a first lift connection and a second lift connection;
• an actuating system moveably connecting the hood to the frame, the actuating system including:
• a driven lever arm rotatably attached to the frame for rotation about a lever rotation axis, the driven lever arm including a first lever connection and a second lever connection positioned opposite each other across the lever rotation axis;
• a first pivot assembly rotatably attached to the frame at a first pivot axis for rotation about the first pivot axis, the first pivot assembly including a first pivot connection offset from the first pivot axis and coupled to the first lever connection of the driven lever arm, and a second pivot connection offset from the first pivot axis and coupled to the first lift connection of the hood;
• a second pivot assembly rotatably attached to the frame at a second pivot axis for rotation about the second pivot axis, the second pivot assembly including a third pivot connection offset from the second pivot axis and coupled to the second lever connection of the driven lever arm, and a fourth pivot connection offset from the second pivot axis and coupled to the second lift connection of the hood;
• and
• wherein the first pivot axis and the second pivot axis are spaced apart from each other along a central longitudinal axis of the frame.
