A pick-up header for a combine is designed to improve the control of the material from a windrow as it is picked up from the ground and transported to the feeder housing of the combine. Immediately rearwardly of the pick-up fingers is provided an air transportation device including a plurality of openings through which air is forced to carry the material rearwardly toward the feeder housing while allowing the escape of stones. Rearwardly of the air transportation device is a sheet which inclines downwardly toward the curved feeding surface of the feeder housing with the pick-up, air transportation device and guide sheet all pivotally mounted relative to the feeder housing. A feed roller includes a plurality of fingers which rotate with the roller about an eccentric axis so that the fingers project outwardly at the front of the roller to a length extending just to the rear of the pick-up fingers and then retract at the rear of the roller. The roller is of larger diameter than conventional allowing the fingers to project forwardly to a greater extent than conventional.

A pick-up for crop material in a swath for feeding into a feeder housing of a combine harvester, the pick-up comprising frame means, means for attachment of the frame means to the feeder housing, a feed pan member having a width transverse to a direction of motion of the combine greater than the feeder housing and arranged to define a surface over which the crop material travels for passage into the feeder housing, a cylindrical auger element mounted above the pan member with a longitudinal axis thereof transverse the direction of movement including flight means mounted on a peripheral surface of the auger element for driving the crop material inwardly from sides of the pan member toward the feeder housing, a pick-up member at a front of the pick-up including a plurality of pick-up elements rotatable about an axis transverse to said direction of movement for lifting the crop material from the ground over the pick-up member, and a conveyor member arranged to provide force on the crop material at a position rearwardly of said pick-up member for transporting the crop material from said pick-up member onto said pan member, the conveyor member defining a conveyor surface including opening means therein and means for generating an air flow through the opening means providing a force on the crop material in an upward and rearward direction.
