    摘要： A 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 vehicle allowing a simplified operation to open and close a shutter in a simple configuration is provided. The shutter can be disposed alternatively at a first position at which the shutter protrudes forward from a lower end of a blade or at a second position at which the shutter is farther away from the lower end than at the first position. The controller is configured to receive an input of an operation instruction from an input operation unit for moving the shutter from the second position to the first position, to cause the shutter to move from the second position to the first position. After a lapse of a prescribed time period since the shutter is moved to the first position, the controller causes the shutter to move from the first position to the second position.

    摘要： A circle rotator of a motor grader includes a worm, a worm wheel and a shaft. The worm wheel has an inner peripheral portion, an outer peripheral portion enclosing the inner peripheral portion from outside, and a plurality of first clutch discs to be spline-coupled to the inner peripheral surface of the inner peripheral portion. The inner peripheral portion is made of a material harder than a material of which the outer peripheral portion is made.
