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.

A row unit drive assembly for a cotton harvester having a frame supported for forward movement over the ground at varying ground speeds, the frame supporting a plurality of transversely adjustable row units each having drivable cotton harvesting structure, the row unit drive structure assembly comprising: a source of hydraulic fluid located on the harvester; each row unit including a hydraulic motor drivingly connected to the corresponding cotton harvesting structure; flexible conduit means connected to each hydraulic motor for supplying fluid from the source to the motor to drive the harvesting structure and facilitating transverse adjustment of the row units without disassembly of the drive structure assembly; a sensor for providing a signal dependent on the ground speed of the harvester; and flow-control means located between the source and the hydraulic motor and responsive to the ground speed signal for causing the motor to drive the harvesting structure at a speed dependent on the ground speed of the harvester.
