The battery is between a front travel device and a rear travel device in a side view, and below a floor of the operation section.

Work vehicle

A self-driving work vehicle including a traveling apparatus, a vehicle body supported by the traveling apparatus on ground, a variable traveling power supply apparatus configured to supply rotational drive power to the traveling apparatus, a travel operation interface configured to adjust a rate of the rotational drive power, a parking brake provided for a transmission shaft of the variable traveling power supply apparatus, a rotation detector configured to detect rotation of the traveling apparatus or the transmission shaft, and a controller. The controller is configured or programmed to control the parking brake to a braking state or a non-braking state by a parking brake control module, and manage the braking state or the non-braking state as a vehicle body state by a condition management module. The braking state and the non-braking state are operating states of the parking brake.
