    Abstract: 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.

    Abstract: A work vehicle includes a vehicle frame, a radiator, an engine, a first post-treatment apparatus, a second post-treatment apparatus, and a bracket. The engine is provided in front of the radiator. The first post-treatment apparatus and the second post-treatment apparatus are positioned in front of the radiator and treat exhaust from the engine. The bracket is positioned in front of the radiator and is elastically supported by the vehicle frame. The bracket supports the engine, the first post-treatment apparatus, and the second post-treatment apparatus. Both the highest position of the first post-treatment apparatus and the highest position of the second post-treatment apparatus are no higher than the highest position of the radiator.

    IPC: E01H5/06

    Abstract: 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.
