Abstract
Picking unit drive structure for transversely adjustable row units of a cotton harvester. A hydraulic drive system with an engine driven pump supplies fluid under pressure through flexible conduits to individual hydraulic motors located on the row units and drivingly connected to the unit harvesting structures. Flow to the motor is regulated by a flow-control valve and an electronic valve controller to synchronize picker drum speed with harvester ground speed. The hydraulic drive eliminates external drive shafts and significantly enhances transverse adjustment of the row units.
