Abstract

A mechanism for spring loading a transport lock on a crop harvesting machine having a pivotally movable tongue mounted to the frame of the harvesting machine, commonly referred to as a pivot-tongue windrower, is disclosed wherein first and second springs are compressible to exert a biasing force on a locking pin to urge the pin through suitable aligned apertures in the base of the tongue and in the frame of the machine to automatically extend the locking pin through the apertures when they become aligned due to manipulation of the pivotal movement of the tongue by the operator at a location remote from the locking pin. An actuating lever includes a camming surface that is selectively cooperable with either the bight portion of the housing or the base plate on the tongue to effect a compression of the first and second springs, respectively, to bias the locking pin toward either a locked or unlocked position. The lever maintains the respective spring in compression until the locking pin moves into the position in which it is being urged.
