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.

Agricultural work assistance system, agricultural work assistance apparatus, and agricultural machine

A travel line creation system for an agricultural machine, includes a position acquirer to acquire position measurement points for the agricultural machine, a display, a first generator to associate the position measurement points with a field displayed by the display and generate creation points on the field by shifting the position measurement points inward in an agricultural field, a second generator to create a travel line including a loop which passes through the creation points and calculate each of virtual lines by connecting together adjacent ones of the creation points, and a setter to extract a pair of virtual lines adjacent to each other and extending in different directions and set, as a work point regarding a breakpoint in work performed by a working device, one of the creation points shared by the extracted pair of virtual lines.

Travel line creation system for agricultural machine

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.

Agricultural machine and agricultural assistance system

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 Wof a work deviceis larger than a lateral width Wof 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 Dbetween a front end position of a work vehicleand a reference position SP at which the work deviceis switched from a working state to a non-working state.
