Abstract: A windrow merging implement with a pick-up, a conveyor and a connecting hitch or structure is provided in combination with a mowing vehicle, with the connecting hitch being releasably secured to a rear end of the vehicle chassis. The mowing vehicle is operative to form windrows of crop in one or more of three locations, namely, a central location passing longitudinally between the wheels of the vehicle and one on each side of the vehicle. The windrow merging implement may be positioned at either side of the vehicle for picking up the windrow deposited there, and includes a conveyor structure for either depositing the picked up windrow upon or alongside the centrally deposited windrow. Also disclosed is an embodiment where the windrow merging implement picks up and displaces transversely the centrally deposited windrow.

Abstract: A pull-type mower-conditioner has a windrow grouper mounted to its main frame by a mounting frame that is swingable between lowered working and raised non-working positions. The grouper includes a conveying arrangement defined in part by a belt conveyor mounted to the mounting frame for free pivotal movement, between angularly spaced stops, about a transverse horizontal axis. When the mounting frame is in its working position, the crop-receiving surface of the conveyor is inclined at a slight angle downward toward the rear of the mower-conditioner with gravity holding the conveyor in position against one of the stops. When the mounting frame is in its non-working position, gravity holds the conveyor in a position rotated against the other of the stops, the crop-receiving surface then being almost vertical so that the grouper is almost within the length of the mower-conditioner.
