ABSTRACT:
A cotton harvester (10) is provided with several independently hydraulically adjustable header units (16) that are movable in unison or completely independently responsive to ground plane elevation. A rotary flow divider (30) is positioned between a manual control valve (32) and the header units to control synchronous movement of the units. A plurality of one way check valves (44 and 104) are positioned between the manual control valve and the rotary flow divider (30) and the header units respectively for prioritizing fluid flow from the manual control valve to the adjustable header units.
