Abstract
An apparatus for inverting a windrow of agricultural crop material on the ground as the apparatus moves along the windrow in a first direction has a lifting mechanism for lifting the crop material from the ground substantially without destroying the integrity of the windrow as the apparatus moves in the first direction. In addition, a transporting mechanism receives the crop material from the lifting mechanism and positively transports the crop material along a generally semicircular path substantially also without destroying the integrity of the windrow so that the crop material is positively transported generally in the first direction when it reaches an exit location where the crop material is dropped to the ground. The continued movement of the crop material by the transporting mechanism results in the crop material passing the exit location so that a lower surface of the windrow is repositioned to a top of the windrow.
