Claims

[Scope of utility model registration request]

In a mobile agricultural machine in which the main gear shift lever, which can be fixed at any operating position provided on the driver's seat, and the hydraulic continuously variable transmission, which is capable of forward and reverse rotation, are interlocked via a connecting member to change the traveling speed, A sub-shift lever is provided in another working part, the sub-shift lever is capable of being linked to a shift shaft for changing the swash plate angle of the continuously variable transmission, and furthermore, the connection between the shift shaft and the main shift lever is released. A travel operating device for a mobile agricultural machine, characterized in that a release means is provided, and the release means is operated in conjunction with a speed change operation of an auxiliary shift lever.
