Abstract
Embodiments of the invention are directed to apparatus for selectively inverting one or more windrows of crop material on the ground as the apparatus is moved in a forward direction, each of the windrows having a lower surface and a generally defined width, the apparatus comprising, a frame for attachment to a vehicle, a first transport mechanism for picking up the crop material of a windrow, moving the crop material in a rearward direction, turning the crop material through a generally horizontal arc and depositing the turned crop material in an inverted condition, the first transport mechanism being movable between a raised non-operating position and a lowered operating position, a second transport mechanism having substantially the same structure and functionality as the first transport mechanism, and a hydraulic control system selectively moving the transport mechanisms between the raised and lowered positions and for driving the transport mechanisms.
