Abstract: A working machine includes a machine body, a lifting device to link a working device to the machine body, the lifting device being capable of moving up and down with the working device between a grounding state in which the working device is in contact with a ground and an ungrounding state in which the working device is out of contact with the ground, and an automatic travel controller to cause the machine body to perform automatic travel according to a planned travel route. The automatic travel controller includes a lifting controller to control the lifting device to move up with the working device from the grounding state to the ungrounding state, and cause the machine body to turn or travel rearward after the lifting controller controls the lifting device to move up with the working device from the grounding state to the ungrounding state.

Abstract: A working machine includes a machine body capable of traveling, a position detector to detect a position of the machine body, and a controller to control the machine body based on the position of the machine body detected by the position detector and a planned travel route. The planned travel route includes a straight section on which the machine body travels straight, and the controller includes a threshold setter to set a threshold according to work, and causes the machine body to perform a recovery movement to make a deviation between the position of the machine body detected by the position detector and the planned travel route less than the threshold when the machine body is at a start point of the straight section or is about to enter the start point of the straight section.

Abstract: An agricultural machine includes a traveling vehicle body, a coupler to couple a working implement with the traveling vehicle body, and a takeoff/landing station to restrict a skid of an unmanned aerial vehicle when the unmanned aerial vehicle takes off or lands. The agricultural machine includes a protector to protect an operator's seat. The takeoff/landing station is provided on the protector. The takeoff/landing station is attached to the protector and includes an arm extending in a horizontal direction when the unmanned aerial vehicle takes off or lands.

Abstract: A travel control system includes a permission unit that permits outermost periphery automatic traveling if predetermined permission conditions are satisfied. The permission conditions include a first condition and a second condition. The first condition is that a reference value corresponding to a working width W1 of a work device 30 is larger than a lateral width W2 of the work device. The second condition is that the reference value is larger than a threshold value determined by a threshold value determination unit. The threshold value determination unit determines the threshold value based on a reference distance D1 between a front end position of a work vehicle 1 and a reference position SP at which the work device 30 is switched from a working state to a non-working state.

Abstract: An agricultural machine includes a vehicle body, a travel switch operable to issue a command to start autonomous travel of the vehicle body, and an autonomous travel controller to perform autonomous travel of the vehicle body based on a planned travel line when the command is issued. When the command is issued by operating the travel switch, if at least one of a positional deviation between the planned travel line that is selected and the vehicle body and an orientational deviation between the planned travel line and an orientation of the vehicle body is greater than or equal to a corresponding one of respective first thresholds, the autonomous travel controller is configured or programmed to perform line alignment to make the positional deviation and the orientational deviation less than the respective first thresholds.

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.
