A traveling work vehicle includes a gear-shifting control unit (6) that outputs a gear-shifting control command to a main gear-shifting apparatus (30) for shifting gears without cutting off power transmission, a sub gear-shifting apparatus (31) for shifting gears by cutting off power transmission, and a first operation unit (MU) and a second operation unit (SU) that provide gear-shifting, upshifting or downshifting, operation commands to the gear-shifting control unit. The gear-shifting control unit (6) has a first travel control section (61) that generates a gear-shifting control command for shifting gears in the main gear-shifting apparatus (30) in response to the gear-shifting operation command from the first operation unit (MU) in a work traveling mode, and a second travel control section (62) that generates a gear-shifting control command for shifting gears in the sub gear-shifting apparatus (31) in response to the gear-shifting operation command from the second operation unit (SU) in the work traveling mode.
