Abstract
A pickup reel for a harvesting machine comprising a reel support and a first shaft rotatably supported by the reel support and extending along an axis transverse to the frame. A cam is supported by the reel support and defines a generally endless cam path extending about the first shaft. An arm extends radially from the first shaft and is rotatable with the first shaft. A second shaft is connected to the arm and supports a first tine and a second tine located on opposite axial sides of the cam. A cam follower is engageable with the cam and movable along the cam path. A crank arm assembly is connected between the cam follower and the second shaft. The rotation of the first shaft and movement of the cam follower along the cam path cooperate to cause the tips to move along the tip path.
