• a second header section having a plurality of fore and aft extending row units and a second cross-auger section, said second header section pivotably movable about said at least one pivot axis between a raised position and a lowered position;
• at least one actuator coupled to selectively pivotally move said first and second header sections about said at least one axis between said raised and a lowered positions;
