  • Patent number: 6889569
    Abstract: A change speed apparatus for a working vehicle includes a first shaft for receiving driving torque from an engine, a second shaft for transmitting the driving torque to a rear wheel differential, a change speed mechanism for changing speed of the driving torque received from the first shaft and transmits the driving torque to the second shaft, and a shift lever for selectively switching the change speed mechanism. The change speed mechanism has a high forward speed stage, a low forward speed stage, a backward drive stage, and a neutral stage. The shift lever is movable along a transverse control path for the neutral stage, a first longitudinal control path for the high forward speed stage, a second longitudinal control path for the low forward speed stage, and a third longitudinal control path for the backward drive stage.
