する。Amendment 12/25/2012 The brief description of the drawing is amended as follows. " in the specification, page 20, lines 19 to 20
FIG. 8 is a diagram showing patterns during steering operation and changes in operating load. '' has been corrected to read, ``Figure 8 is a circuit diagram of the hydraulic operation system, and Figure 9 is a diagram showing the pattern during steering operation and changes in operating load.''

Claims

[Scope of utility model registration request]

The transmission 1 includes a speed change gear 13 for traveling speed operated by a speed change lever 65, a forward rotation shaft 19 and a reverse rotation shaft 41 inputted from the speed change gear 13, and a mechanism for cutting off reverse rotation input from the speed change gear 13. a switching clutch 43 in contact with the switching clutch 43;
In this mechanism, the gear shift lever 65 is also used as an operating lever for the switching clutch 43, and the gear shifting lever 65 is used to operate the switching clutch 43 only in non-high speed ranges. A turning operation mechanism for a traveling work vehicle, which is provided with a lever guide 66 for a gear shift lever 65 that can be operated to "on".
