Claim 19:
20. A crop conditioning system for a harvesting apparatus, the crop conditioning system comprising:
a frame;
a crop conditioning element;
a hood moveable toward and away from the crop conditioning element to define a gap therebetween, the hood including a first lift connection and a second lift connection;
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.
