Abstract
Abstract A method of harvesting forage crops such as hay including novel windrow maintenance steps which improve the curing thereof in the field and enable an earlier harvest of a second crop thereof is disclosed. A machine specifically adapted to perform the windrow maintenance steps of such process is described. The machine includes a main platform having a back wall and an end wall, means for picking up a windrow of the crop and placing it on the main platform, means for moving the crop along the platform away from the end wall and means for replacing the windrow on the ground.
