    摘要： A work vehicle capable of notifying surroundings about information of the work vehicle at appropriate timing is provided. The work vehicle includes a blade, a shutter, a notification unit, and a controller. The blade includes a lower end. The shutter is attached to the blade. The shutter can be alternatively disposed at a first position at which the shutter protrudes forward from the lower end of the blade or at a second position at which the shutter is farther away from the lower end than at the first position. The notification unit is configured to notify surroundings of the work vehicle about information of the work vehicle. The controller is configured to change information notified by the notification unit in accordance with an arrangement of the shutter at one of the first position and the second position.

    摘要： A work machine is provided that can achieve an automatic brake retention function without hindering work. The work machine includes a vehicular body that travels, a work implement supported on the vehicular body, an accelerator operation device operated to increase a traveling speed of the vehicular body, a brake operation device operated to decrease the traveling speed of the vehicular body, and a controller. The controller performs automatic brake retention control to retain a braking force to maintain a travel-stopped state of the vehicular body when the traveling speed of the vehicular body becomes less than or equal to a threshold by operation of the brake operation device, and release the retention of the braking force by operation of the accelerator operation device. The controller determines whether work is being performed by the work implement, and when work is being performed, disables the automatic brake retention control.

    摘要： A vehicle body cover of a work vehicle is provided with an outside ventilation cover part and an inside ventilation cover part. The outside ventilation cover part has outside ventilation holes that communicate with an external space. The outside ventilation cover part is disposed in an inclined manner with respect to the vertical direction. The inside ventilation cover part is disposed to face the outside ventilation holes on the inside of the outside ventilation cover part. The inside ventilation cover part has a rain gutter part and a ventilation part. The rain gutter part is configured to receive water entering from the outside ventilation holes. The ventilation part has inside ventilation holes that communicate with a space on the inside of the inside ventilation cover part. The ventilation part is disposed above the rain gutter part.

    摘要： A motor grader includes an operation apparatus, a front frame, a draw bar swingably attached to the front frame, a first actuator attached to the draw bar, the first actuator moving the draw bar in a lateral direction with respect to the front frame, a second actuator attached to the draw bar, the second actuator moving the draw bar in a direction toward the front frame and a direction away from the front frame, and a controller that causes the first actuator and the second actuator to operate. The controller causes the first actuator and the second actuator to operate based on an operation signal received from the operation apparatus such that a position of the draw bar with respect to the front frame comes closer to a neutral position of the draw bar with respect to the front frame.

    摘要： A motor grader includes an operation apparatus, a swing circle, a blade supported on the swing circle, a first actuator arranged along a longitudinal direction of the blade, the first actuator moving the blade in a lateral direction with respect to the swing circle, and a controller that causes the first actuator to operate. The controller receives an operation signal from the operation apparatus and causes the first actuator to operate based on the received operation signal such that a position of the blade with respect to the swing circle comes closer to a neutral position of the blade with respect to the swing circle.

    摘要： Detection accuracy of a device for obtaining a position of a blade is improved. A motor grader includes an antenna for reception of a satellite position determination signal arranged in a roof portion of a cab, a first IMU mounted on the cab, a second IMU mounted on a draw bar, a rotation angle sensor that detects an angle of rotation of a swing circle with respect to the draw bar, an inclination angle sensor that detects an angle of inclination of a blade with respect to the swing circle, and a controller. The controller obtains the position of the blade in a global coordinate system based on the satellite position determination signal received by the antenna and results of detection by the first IMU, the second IMU, the rotation angle sensor, and the inclination angle sensor.
