Claims

[Scope of utility model registration request]

In a mobile agricultural machine in which traveling speed is achieved by interlocking a main gear shift lever provided on the driver's seat that can be fixed at any operating position and a hydraulic continuously variable transmission that can be forward-reverse reversed via a connecting member, A sub-shift lever is provided in another working part, and the sub-shift lever is connectable to the shift shaft for changing the swash plate angle of the continuously variable transmission through a connecting/disconnecting means, and the sub-shift lever is connected to the shift shaft for changing the swash plate angle of the continuously variable transmission. A traveling operating device for a mobile agricultural machine, characterized in that the connecting/disconnecting means is switched from a disconnected state to a connected state in conjunction with each other to perform traveling speed change.
