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

An agricultural machine comprising:

• a traveling body that is capable of traveling;
• a coupler that is capable of coupling a working device to the traveling body;
• a controller including a processor and a memory;
• a touch panel connected to the controller;
• and
• a positioning system connected to the controller to detect a position of traveling body;
• wherein
• the controller is configured or programmed to:
• cause the memory to store dimension information input by an operator via the touch panel, indicating an entire width, a work width, an entire length, and a work end position at which the working device ends the ground work from a coupling position of the working device coupled to the traveling body and a work condition for performing agricultural work on an agricultural field by the agricultural machine and the working device;
• create a traveling route of the traveling body on a map indicative of the agricultural field on a basis of the dimension information of the working device and the work condition;
• determine whether or not the working device or the agricultural machine has crossed a boundary out of the agricultural field on a basis of the position of the agricultural machine, the map, the dimension information of the working device, and dimension information of the agricultural machine;
• stop traveling of the agricultural machine based on the traveling route when it is determined that the working device or the agricultural machine has crossed the boundary out of the agricultural field;
• determine that the dimension information of the working device input by the operator via the touch panel does not satisfy a predetermined restriction condition when the entire width is less than the work width or when the entire length is less than a length to the work end position, with the agricultural work performed by the working device including either one of a cultivation work, a puddling work, or a stubble cultivation work;
• and
• delete the dimension information of the working device from the memory to prevent creation of the traveling route of the agricultural machine and determination of whether or not the working device or the agricultural machine has crossed the boundary out of the agricultural field in a case where it is determined that the dimension information does not satisfy the restriction condition.
