A working machine includes a machine body, a steering device capable of changing an orientation of the machine body, a first wheel on the machine body, a second wheel on the machine body and separated from the first wheel in a machine-body width direction, a rotational difference generator to cause a rotational difference between the first and second wheels and that is a braking device, and a controller configured or programmed to include a first control unit to set a steering angle of the steering device based on a planned traveling route, and a second control unit to control the rotational difference generator based on the planned traveling route to cause a rotational difference between the first and second wheels. Based on the planned traveling route, the second control unit is configured or programmed to cause the braking device to perform setting about braking of either the first or second wheels by performing pumping control.

Working machine

An agricultural support system includes a terminal to hail a self-driving agricultural machine to a hailing point, and a processor to generate, in an area excluding an already-worked area of the agricultural machine, a travel route for the agricultural machine to head toward the hailing point.

Agricultural support system, and device and method to generate travel route for hailed agricultural machine

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.

Agricultural machine

An agricultural machine includes a traveling vehicle body, a detector to detect objects in an area surrounding the traveling vehicle body, a detection adjuster to adjust a detection direction of the detector, a position sensor to detect a position of the traveling vehicle body, and an information acquirer to acquire information relating to an entrance/exit of an agricultural field. The detection adjuster is operable to perform a first adjustment of orienting the detection direction toward an end point of the entrance/exit when the traveling vehicle body is traveling toward the entrance/exit and a distance from the position of the traveling vehicle body to the entrance/exit included in the information is a predetermined value or less, and a second adjustment of orienting the detection direction toward the end point of the entrance/exit or a space forward of the end point in a traveling direction when the traveling vehicle body is traveling on the entrance/exit.

System to adjust object detection direction for agricultural machine

An agricultural support system includes a first communication device located in or on a tractor to transmit information, and a second communication device located in or on a transport vehicle to acquire the information transmitted from the first communication device. The transport vehicle is capable of transporting the tractor. The agricultural support system further includes a position sensor in or on the working machine to detect a position of the working machine. The first communication device is operable to transmit the position detected by the position sensor to the second communication device as the information. The second communication device is operable to receive the position transmitted from the first communication device.
