Abstract: A vehicle control device causes the work machine to execute automatic travel when an automatic travel button is operated by an operator in a state where a guidance screen relating to automatic travel of a work machine is displayed on an operation terminal, and does not cause the work machine to execute automatic travel when the automatic travel button is operated by the operator in a state where a non-guidance screen is displayed on the operation terminal.

Abstract: The operation control method displays a horizontal control operation screen relating to horizontal control that controls a tilt of a work implement with respect to a machine body, for a work machine including a machine body, and a work implement attached to the machine body. The setting related to the horizontal control is performed in accordance with an operation of a user on a control operation unit included in the horizontal control operation screen.

Abstract: Provided is a display device for a tractor that displays states of a work machine connected to the tractor in an easy-to-understand manner. The present invention is configured to have: a work machine display section indicating an operational state of a work machine at the center of a screen of a display; a depth display section showing a work depth of the work machine in a region on the right side of the display region of the work machine display section; an inclination display section showing the inclination of the work machine in a region below the display region of the work machine display section; various sensors for detecting states of the work machine such as the operational state of the work machine, the work depth of the work machine, and the inclination of the work machine; switches for switching the display contents on the screen; and a control unit for controlling the display sections, the sensors, and the switches.

Abstract: This tractor includes a work machine, a control device, and an imaging unit. The control device operates as a work machine state detection unit and a display control unit. The work machine state detection unit detects a work machine state relating to the work machine. The imaging unit acquires a work image by imaging the status of work performed by the work machine. The display control unit displays simultaneously on a display device a first display area that displays the detected work machine state, and a second display area that displays the acquired work image.

Abstract: A tractor, which is a work vehicle, includes a control device. The control device operates as a travel control unit and a work control unit that perform work travel in a field, and a finish detection unit (detection unit) that detects a finish level of the work at each work position in the field after performing the work travel.

Abstract: An automatic traveling method includes causing a work vehicle to automatically travel according to a target route in a farm field, execute a spraying work of spraying a chemical liquid on crops, execute a stirring work of stirring the chemical liquid in a storage tank, and start the stirring work if a predetermined condition is satisfied before the work vehicle starts automatic travel.
