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. A further embodiment discloses two windrow merging implements which respectively pick up the windrows at the opposite sides of the vehicle and convey them inwardly so as to be combined with the centrally located windrow.
