  • Traveling vehicle
    Patent number: 11533901
    Abstract: A traveling vehicle includes a controller to control a posture of a work machine via a connector. The controller observes whether a farm field surface on which the traveling vehicle travels and the work machine maintain a predetermined positional relationship therebetween, and controls the posture of the work machine when a positional relationship between the farm field surface and the work machine changes from the predetermined positional relationship, so that the positional relationship thus changed is reset to the predetermined positional relationship.
    Type: Grant

    Inventors: Shinnosuke Ishikawa, Komei Yamawaki, Ryo Kurata
  • Work vehicle
    Patent number: 11536356
    Abstract: A work vehicle includes an engine, a speed changing apparatus that includes a hydrostatic stepless speed changing mechanism and is configured to subject motive power transmitted from the engine to speed changing and output the motive power, a travelling apparatus configured to travel on the motive power received from the speed changing apparatus, a speed detector configured to detect a speed of the travelling apparatus, a pressure detector configured to detect a hydraulic pressure in a closed circuit of the hydrostatic stepless speed changing mechanism, and a controller.
