Abstract: An agricultural work assistance system includes a display to display a map representing an agricultural field, and a controller configured or programmed to define or function as an area setter to set a first area and a second area located inward of the first area in the map displayed by the display, and a route creator to create, in at least one of the first area or the second area, a travel route along which an agricultural machine is to travel. The route creator is configured or programmed to set at least a portion of the travel route as an automatic steering route on which the agricultural machine is to be automatically steered and a travel speed of the agricultural machine is to be changed manually.

Abstract: A work vehicle includes: an electronic control system for automatic driving; and a cabin with which a boarding space is formed. The electronic control system includes an antenna unit for satellite navigation, and the antenna unit is attached to a central area of a roof of the cabin in a left-right direction. An upper surface of an area of the roof around the antenna unit is formed so as to be an inclined surface that is inclined in a front-rear direction. Left and right end portions of the roof are provided with left and right bulging edge portions that bulge upward from the left and right end portions and have a length that spans between front and rear ends of the roof, and water drain grooves that guide water on the roof toward the left and right bulging edge portions such that water detours the antenna unit.

Abstract: A working vehicle includes a vehicle body, a linkage provided on the vehicle body to link a working device, a controller to cause the vehicle body to perform automatic travel, a rear obstacle detector to detect obstacles behind the vehicle body, and a setting changer to change rear setting information regarding obstacle detection performed by the rear obstacle detector.

Abstract: A controller for a work machine includes a steering control circuit, a memory, and a speed control circuit. The steering control circuit is configured to control a steering of the work machine to change a steering angle based on a travel route. The memory is to store a threshold angle. The speed control circuit is configured to control a speed of the work machine if the steering angle is equal to or larger than the threshold angle and if the steering control circuit does not control the steering.

Abstract: A controller for a master work vehicle, includes a wireless circuit, an acquisition circuit, a message generation circuit, and a display control circuit. The wireless circuit is to receive, from a slave work vehicle configured to travel automatically, first information indicating a state of work travel of the slave work vehicle. The master work vehicle is configured to work in cooperation with the slave work vehicle. The acquisition circuit is configured to acquire second information indicating a state of work travel of the master work vehicle. The message generation circuit is configured to generate a first message based on the first information and a second message based on the second information. The display control circuit is configured to control a display to display the first message and the second message.

Abstract: To properly manage data collected by a data collection device even when the data collection device is attached to an agricultural machine different from a specified agricultural machine.

Abstract: A travel support system for a work vehicle including a vehicle body and a work device provided on the vehicle body includes a first calculator to calculate a vehicle body occupied area including the vehicle body in a plan view. A second calculator is to calculate a work device occupied area including the work device in the plan view. A third calculator is to calculate a work vehicle occupied area including the work vehicle in the plan view, the work vehicle occupied area including the vehicle body occupied area and the work device occupied area. A position calculator is to calculate a position of the work vehicle in a work field based on positioning data. A controller is to control the work vehicle to move in the work field based on the position of the work vehicle and the work vehicle occupied area.

Abstract: Data on agricultural machines can be outputted to mobile terminals easily and properly. A data collection device is provided separately from a control device that controls the operation of an agricultural machine and is connected to a vehicle communication network installed in the agricultural machine, and is removably connected to the vehicle communication network. The data collection device includes a data collection unit for collecting agricultural machine data outputted to the vehicle communication network, an authorization determination unit for implementing authentication with a mobile terminal to determine whether or not the collected data is transmitted to the mobile terminal by wireless communication, and a data communication unit for transmitting data to the mobile terminal by wireless communication when the authorization determination unit authorizes data transmission.

Abstract: A route search system for a work vehicle includes a receiver, a processor, and a controller. The receiver is to obtain a reference position of the work vehicle. The processor is to define, as a search area, an area around a vehicle reference point in a plan view. The vehicle reference point indicates the reference position of the work vehicle. The controller is to determine a guidance travel route along which the work vehicle is to travel and which is closest to the vehicle reference point in the search area among travel route candidates stored in a memory.
