Abstract: A travel assistance system for an agricultural machine includes a traveling device included in an agricultural machine, an acquirer to acquire a travel route to be traveled by the agricultural machine and created on a field representing an agricultural field, a corrector to correct the travel route acquired by the acquirer, and a controller configured or programmed to control the traveling device based on the travel route corrected by the corrector. The travel route includes lines connected to each other and the corrector includes a creator to create an auxiliary line extending from an ending portion of a first line of the lines to a starting portion of a second line of the lines connected to the ending portion of the first line, the auxiliary line being inclined relative to the second one of the lines.

Abstract: An agricultural machine includes a traveling vehicle body, a position detector to detect a position of the traveling vehicle body, a lifting device to link a working device to the traveling vehicle body, and an automatic operation controller to perform an automatic operation to cause the traveling vehicle body to travel and cause the working device to perform an agricultural job based on a travel route and the position of the traveling vehicle body. The lifting device is operable to, during the automatic operation, place the working device in a work position in which the working device performs the agricultural job, and the automatic operation controller is operable to cause the lifting device to keep the working device in the work position even after stopping the traveling vehicle body and/or the working device to end the automatic operation at a location short of an unworked area of the agricultural field.

Abstract: An agricultural assistance system includes a route creator to create, on a map representing an agricultural field, a travel route along which an agricultural machine travels, an input to receive input of a turn mode which is one of turn modes differing in terms of how a traveling device of the agricultural machine is driven, a position detector to detect a position of the agricultural machine, an automatic operation controller to perform automatic operation in which the automatic operation controller automatically causes the agricultural machine to travel and automatically steers the agricultural machine, and a turn mode changer to, during automatic operation of the agricultural machine, allow the input to receive input of another turn mode to change the turn mode, and output, to the automatic operation controller, a change command to cause the agricultural machine to turn in the other turn mode inputted via the input.
