ABSTRACT:
A mechanism for pivotally moving the windrow forming shield on a crop harvesting machine from a generally horizontally extending operative position to a generally vertically extending transport position is disclosed wherein the pivotal movement of the frame relative to a pivotal axis carried by the draft member effects a pivotal movement of the windrow forming shield. A first sprocket is stationarily fixed to the draft member while a second sprocket orbits about the first sprocket as a result of the frame being pivotally moved about its pivot axis. An endless chain entrained around both the first and second sprockets effects a rotation of the second sprocket during its orbital movement around the first sprocket to cause a rotation of a connected pivot shaft and effect a pivotal movement of the windrow shield. By making the second sprocket half the size of the first sprocket, the windrow forming shield can be moved through 180 degrees of movement while the frame is being rotated 90 degrees.
