  • Patent number: 4085570
    Abstract: A forage harvester and attachment therefor are provided wherein such attachment serves the multiple purposes of cutting, conditioning, and selectively moving a crop in two basic directions from a crop transfer zone within the attachment, one of the directions being toward the ground and the other being away from the ground. The attachment comprises a flail device of predetermined width for cutting and conditioning a standing crop in one mode of operation and for picking up a pre-cut ground swath of a crop in another mode and moving that swath to the transfer zone. The attachment has an auger for gathering a crop into the transfer zone immediately after cutting to define a dense swath thereof which has a width less than that of the flail device and approximately equal to the width of the ground swath. The attachment has an additional auger and a door for selectively moving crop from the transfer zone in the above-mentioned two basic directions.
