ABSTRACT:
A transport lock actuating mechanism for a crop harvesting machine having a pivotally moveable tongue mounted to the frame of the harvesting machine, commonly referred to as a pivot-tongue windrower, is disclosed wherein a single spring is compressed 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. The transport lock actuating mechanism is alternatively operable to exert a biasing force on the locking pin to urge the locking pin into a position withdrawn from the apertures so that the machine can be moved from a transport position to an operating position.
