。 In a structure in which a speed change operation lever and a speed change operation pedal are connected to a pump swash plate of a continuously variable hydraulic transmission mechanism for traveling, the swash plate adjustment member that connects the pump swash plate and the speed change operation pedal is configured to absorb a forward/reverse drive reaction force. The speed change operation lever is interlocked and connected through an element, and when a driving reaction force of a certain level or more is generated on the swash plate during longitudinal running, the swash plate is moved to a neutral position while the speed change operation lever is held at the speed change operation position. A traveling transmission device for a mobile agricultural machine, characterized in that it is configured to perform return control.
