Beschreibung
Zusammenfassung:	A harvester head may include a position adjustable reel having a first segment and a second segment, a hydraulic supply comprising a pump and a reservoir, a first plurality of hydraulic cylinders coupled to the first segment to reposition the first segment, a second plurality of hydraulic cylinders coupled to the second segment to reposition the second segment, a first bidirectional valve operably coupled between the hydraulic supply and the first plurality of hydraulic cylinders, a second bidirectional valve operably coupled between the hydraulic supply and the second plurality of hydraulic cylinders, at least one sensor to sense relative positioning of the first segment and the second segment and a controller. The controller may output control signals to the first bidirectional valve and the second bidirectional valve based upon signals from the at least one sensor to synchronize positioning of the first segment and the second segment.
