Abstract: There is provided an agricultural field work vehicle capable of entering a work travel path intended by the driver in transition from manual turn travel to autonomous work travel. An agricultural field work vehicle includes an autonomous travel control section configured to cause the agricultural field work vehicle to perform autonomous travel on the basis of work travel paths and the position of the agricultural field work vehicle, a manual travel control section configured to control manual travel of the agricultural field work vehicle along a turn travel path, a destination travel path singling-out section configured to single out a destination work travel path from among a group of candidates of destination work travel paths that the agricultural field work vehicle is able to enter from the turn travel path through which the agricultural field work vehicle is driven manually, a notification device configured to notify the driver of path notification information, which is information on the work travel paths, which include the destination work travel path singled out, and an autonomous travel start operation tool for use to instruct the agricultural field work vehicle to switch from controlling the manual travel to controlling the autonomous travel.

Abstract: A traveling vehicle includes a controller to control a posture of a work machine via a connector. The controller observes whether a farm field surface on which the traveling vehicle travels and the work machine maintain a predetermined positional relationship therebetween, and controls the posture of the work machine when a positional relationship between the farm field surface and the work machine changes from the predetermined positional relationship, so that the positional relationship thus changed is reset to the predetermined positional relationship.

Abstract: A working machine includes a vehicle body to which a working device is connectable, a driving estimator to estimate whether the vehicle body is drivable along a road based on a road condition and a device condition, a controller to control a driving operation of the vehicle body based on an estimation result obtained by the driving estimator, and a communicator to transmit to an external device driving information regarding driving the vehicle body under control of the controller. The controller is configured or programmed to drive the vehicle body based on a command received from the external device after transmission of the driving information from the communicator to the external device.
