PROBLEM TO BE SOLVED: To provide an operation mechanism related with traveling for a mobile agricultural machine in which a speed change input member 41 of a traveling HST 38 can be recovered to a position where the speed change input member 41 is accurately aligned with the neutral position p2 of a parking brake operating member when the parking brake operating members 32, 33 are operated at the time of entering a parking state. SOLUTION: The mobile agricultural machine is constituted as follows. A recovery force input member 45, which recovers the speed change input member 41 of the traveling HST 38 to the neutral position p2, is fixed to the speed change input member 41 of the traveling HST 38. The mobile agricultural machine is provided with a recovery force imparting member 44 for imparting the neutral position recovery force with a specified magnitude to be generated by the elastic force of an elastic member 48 to the recovery force input member 45. While, it is provided with the parking brake operating members 32, 33 for regulating rotational operation at a traveling part to which traveling rotation of the traveling HST 38 is transmitted. It is also provided with an interlocking means 50 to interlock the parking brake operating members 32, 33 with the recovery force imparting means 44. The operating force imparted to the parking brake operating members 32,33 increases the neutral position recovery force. COPYRIGHT: (C)2004,JPO
