A two stage hydraulic tongue swing mechanism and a tongue latch mechanism for controlling and affixing the tongue of a pull type implement while the implement is being laterally transported. The two stage hydraulic tongue swing mechanism comprises a tongue plate attached to the tongue. A free plate is pivotally attached at the tongue pivot and is controlled by a hydraulic cylinder. The tongue plate and free plate are selectively attached to each other by a lateral transport latch. The tongue latch mechanism is partly affixed to the tongue and partly to the trailframe. Attached to the tongue is a tongue handle that controls the position of a tongue pin. The tongue pin is biased into an angled strike plate with a slot on the edge of the trailframe. The tongue pin may be held in a retracted position by a notched lock bar.
