ABSTRACT:
To form a double windrow of a grass crop after it has been cut, a windrow grouper is mounted behind a mower conditioner unit. The windrow grouper has an upright rotating drum which is provided with crop-engaging tines, and is positioned to deflect the cut crop into the double windrow when the crop is still in flight from the mower conditioner unit and before it has any substantial contact with the ground. The windrow grouper is swung clear of the crop delivered by the mower conditioner unit to enable an initial windrow to be laid, and then is swung back into the flight path of the crop to form the double windrow.
