摘要： PURPOSE: A speed change apparatus for a working vehicle, which engages in operations while moving forward and backward is provided to improve manipulability of a gearshift lever and simplify the structure of the speed change apparatus. CONSTITUTION: A speed change apparatus for a working vehicle, which engages in an operation while moving forward and backward, includes a first shaft(14) for receiving driving torque from an engine, a second shaft(18) for transmitting the driving torque to a rear wheel differential, a speed change mechanism(9) for changing speed of the driving torque received from the first shaft and transmits the driving torque to the second shaft, and a gearshift lever for selectively switching the speed change mechanism. The speed change mechanism has a high forward speed stage for changing the speed of the driving torque received from the first shaft to a high forward speed for transmission to the second shaft, a low forward speed stage for changing the speed of the driving torque received from the first shaft to a low forward speed for transmission to the second shaft, a backward drive stage for changing the speed of the driving torque received from the first shaft to a low backward speed for transmission to the second shaft, and a neutral stage. The shift lever is movable along shift control paths including a transverse control path extending transversely, a first longitudinal control path extending longitudinally from one side of the transverse control path, a second longitudinal control path extending longitudinally from the one side of the transverse control path and spaced from the first longitudinal control path, and a third longitudinal control path extending longitudinally from the other side of the transverse control path. The high forward speed stage is selected when the shift lever is operated to an end of the first longitudinal control path. The low forward speed stage is selected when the shift lever is operated to an end of the second longitudinal control path. The backward drive stage is selected when the shift lever is operated to an end of the third longitudinal control path. The neutral stage is selected when the shift lever is operated to the transverse control path.
