Abstract
A series of rollers mounted at spaced locations on a windrow pickup about a rear discharge opening defined therein interengage with a circular track mounted on a crop material chopping chamber of a forage harvester and at least partially encircling a front receiving opening defined therein to continuously support the pickup on the chopping chamber in an operating field position, in a non-operating transport position and for pivotal movement relative thereto between the field and transport positions. The interengaging series of rollers and circular track are moveable relative to each other to provide pivotal movement of the pickup relative to the chopping chamber between the field and transport positions within a plane extending in a generally transverse relationship to the direction of movement of the forage harvester across the field and about a pivotal axis located generally at the center of curvature of the circular track.
