Abstract
A hay harvester has a double windrow cross-conveyor supported rearwardly of the harvesting header to receive a stream of conditioned crop materials from the header and transport the same laterally to an outboard position. A deflector adjacent the discharge end of the conveyor is maintained in a lowered position to direct materials to the ground to form a first windrow during a first pass and is then placed in a raised position during a return pass so as to allow the stream discharging from the cross-conveyor to be deposited close to the first windrow, thus forming a double windrow. The cross-conveyor is hingedly affixed to the vehicle in such a manner that the normally tilted down, lower front edge of the cross-conveyor can be raised up into a transport position for higher ground clearance or to switch to single swathing. The header and cross-conveyor are preferably plumbed in a parallel fluid flow relationship so that they are raised or lowered simultaneously.
