  • Patent number: 12268113
    Abstract: An agricultural machine includes a vehicle body, a travel switch operable to issue a command to start autonomous travel of the vehicle body, and an autonomous travel controller to perform autonomous travel of the vehicle body based on a planned travel line when the command is issued. When the command is issued by operating the travel switch, if at least one of a positional deviation between the planned travel line that is selected and the vehicle body and an orientational deviation between the planned travel line and an orientation of the vehicle body is greater than or equal to a corresponding one of respective first thresholds, the autonomous travel controller is configured or programmed to perform line alignment to make the positional deviation and the orientational deviation less than the respective first thresholds.

  • Patent number: 12017526
    Abstract: There is configured a work machine whose engine and fuel tank will not be damaged at time of a work even when the engine and the fuel tank are arranged with offset to one side in the left/right direction of the machine body. The work machine includes a machine body that can travel with left and right front wheels and left and right rear wheels and an implement supported to the machine body. An engine driving the front wheels, the rear wheels and the implement and a fuel tank are disposed between the front wheels and the rear wheels in a front/rear direction of the machine body and at positions offset to further outer side than the left/right center of the machine body. There is provided a protection member which protrudes to a further outer side than an outer end position of the fuel tank in an offset direction of the fuel tank.

  • Publication number: 20240107931
    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.

  • Patent number: 11696525
    Abstract: The present invention provides an autonomous traveling work machine that can accurately receive positioning signals from navigation satellites and autonomously travel without deviating from a traveling path, even in the case of an inclined slope. The autonomous traveling work machine includes a traveling machine body, a positioning receiver that receives positioning signals from navigation satellites, an autonomous traveling control device that performs control for autonomous traveling along traveling paths based on the positioning signals, an inclination detection unit that detects the inclination of the traveling machine body and outputs inclination angle information, an inclination angle determination unit that determines an inclination angle based on the inclination angle information, and a rotation control mechanism that rotates the positioning receiver with one or more degrees of freedom. The rotation control mechanism keeps the positioning receiver horizontal based on the inclination angle.
