Abstract
Apparatus for collapsing an on-board crop receiver of a harvester to a transport position, utilizing a remotely releasable locking element to allow telescopic collapsing or retracting the receiver without entering the receiver, and powered apparatus for positively collapsing a duct extending between a row unit of the harvester and an inlet opening of the receiver. The duct is telescopically retractable at an inclined angle by a similarly inclined duct driver to a height about equal to that of the receiver when in the transport position, so as to be freed from the receiver and any associated hood extending outwardly therefrom associated with the inlet opening. Using crop compactor apparatus within the interior of the receiver, the compactor can be lowered and the locking mechanism unlocked, and then the compactor operated to telescopically collapse or retract the receiver. The receiver can be extended in the reverse order.
