  • Patent number: 3983683
    Abstract: A crop harvesting machine is disclosed wherein tines of a transversely extending oblique reel pickup device pick up crop material from the ground and feed it into the crop harvesting machine. The oblique reel causes the tines to have velocity components parallel to the reel axis which are substantially greater than their velocity components parallel to the harvesting machine's forward motion as they feed the pre-severed crop material transversely into the crop harvesting machine. The tines are spaced relatively far apart yet provide efficient interception and clean-up of crop material from the ground.A second embodiment of a transversely-extending oblique reel pickup device is disclosed wherein tines pick up pre-severed crop material backwardly and below the reel.A u-joint type linkage member is disclosed herein to couple tine bars to spiders along with cam and followers in oblique reel pickup devices.A link-and-lever system is described for rotating the bars of oblique reel pickup devices.
