ABSTRACT:
A laterally shiftable draper header for a windrower is disclosed wherein a pair of draper sections are laterally shiftable on the header subframe to vary the position of the crop discharge opening between left, right and central positions. When the discharge opening is positioned at a central location between separated draper sections, it is necessary that the draper conveyors rotate in opposing directions to deliver crop material to the discharge opening. However, when the draper sections are positioned adjacent one another and shifted to one side of the machine or the other it is necessary for the draper conveyors to rotate in the same direction to convey crop to the discharge opening. A reversing mechanism for changing the direction of rotation of one of the draper sections relative to the other in response to the relative position of the other draper section is provided and includes a push rod for sensing the proximate location of the other draper section to cause the associated draper conveyor to reverse direction of rotation.
