ABSTRACT:
An agricultural harvesting combine is provided with a hydraulically positioned reel at the forward end of the combine. One single acting hydraulic cylinder is carried at each end of the reel. Hydraulic fluid is supplied to the cylinders through a rotary flow divider to cause each cylinder to synchronously be displaced to raise both ends of the reel in unison.
