Abstract

A hay harvesting machine in which previously cut crop material in a windrow or swath on the ground is picked up and inverted to position a damp side up and a dry side down; as the crop is inverted, it is directed laterally toward one side of the machine and rearwardly; after inversion, the crop is turned further and conveyed for discharge back onto the ground laterally displaced from its original position on the ground.
