    Abstract: A work vehicle includes: a display device provided in a cab and configured to display work assistance information to be overlaid on an actual view of a work site; a bucket position detector configured to detect a position of a bucket; and a display controller configured to control a content to be displayed on the display device and configured to cause the work assistance information to be displayed around the bucket while causing the work assistance information to follow the movement of the bucket based on the detected position. When work assistance information becomes close to a boundary of a display area of the display device due to the movement of the bucket, the display controller is configured to cause the work assistance information to be displayed on the display device with a relative position between the work assistance information and the bucket in the display area being changed.

    Abstract: A work implement includes a breaker. Sensors detect an attitude of the work implement. A pilot valve controls the operation of the breaker. A controller controls the pilot valve. The controller detects, from the attitude of the work implement obtained by the sensors, a distance between a tip of the breaker and a striking limit. When it is determined that the tip of the breaker has reached the striking limit, the controller controls the pilot valve to stop the operation of the breaker.

    Abstract: A work vehicle includes a work implement, a main body, a display device, and a display controller. To the main body, the work implement is attached, and the main body has a cab. The display device is provided in the cab and configured to overlay and thus display work assistance information on an actual view of a work site. The display controller causes the display device to display target design topography as work assistance information. When a work starts, the display controller causes the display device to display final target design topography that is achieved after the work is completed, and subsequently, switches to displaying target design topography to be achieved depending on a working step performed.

    Abstract: A work vehicle includes: a main body having a cab; a display device provided in the cab and configured to display work assistance information to be overlaid on an actual view of a work site; a display controller configured to cause the work assistance information to be displayed on the display device; and a bucket position detector configured to detect a position of a bucket relative to the main body. The display controller is configured to cause a display position of the work assistance information on the display device to follow a movement of the bucket. The display controller is configured to change a display manner of the work assistance information on the display device based on the position detected by the bucket position detector, when the bucket is moved relative to the cab in a forward direction and a rearward direction.

    Abstract: A work vehicle includes a reducing agent tank, a battery, a reducing agent tank mounting member, a battery cover and a first guide member. The battery and the tank are positioned in a row. The mounting member has a bottom plate, and a partition plate extending upward from the bottom plate between the tank and the battery. The tank is mounted on the bottom plate. The battery cover has an upper plate above the battery, and a side plate extending downward from a side of the upper plate between the tank and the battery. The first guide member extends from the side plate toward the tank and slopes downward. Preferably, a first end of a second guide member disposed below the first guide member is positioned closer to the battery than a distal end of the first guide member, with the second guide member sloping downward toward the tank.

    Abstract: A work vehicle includes a traveling unit, a revolving unit disposed on an upper side of the traveling unit, a work implement disposed on the revolving unit, a revolving driver that revolves the revolving unit, a receiver, an end position setting component, a revolution position sensor, and a drive controller. The receiver directly or indirectly receives information related to a position of an object serving as a target of a revolution of the revolving unit, from the object. The end position setting component sets an end position of a revolution of the revolving unit based on information related to the position of the object. The revolution position sensor senses a revolution position of the revolving unit during a revolution. The drive controller controls the revolving driver based on the revolution position to revolve the revolving unit from a start position of a revolution to the end position.
