Abstract: A work vehicle includes: a hydraulic operation apparatus for operating an actuator; a main controller configured to generate a command current in accordance with an amount of operation of the operation apparatus; an electromagnetic proportional control valve configured to generate command pilot pressure in accordance with the command current; and a main valve configured to adjust a flow rate of hydraulic oil for operating the actuator based on the command pilot pressure. The electromagnetic proportional control valve is provided in a pilot oil passage that connects a pilot pump and a main valve, and configured to utilize hydraulic pressure supplied from the pilot pump to generate command pilot pressure. The operation apparatus is provided in an operation apparatus oil passage that is different from the pilot oil passage.

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 translation: 工作车辆包括还原剂罐，电池，还原剂罐安装构件，电池盖和第一引导构件。 电池和水箱位于一排。 安装构件具有底板和从罐和电池之间的底板向上延伸的隔板。 油箱安装在底板上。 电池盖具有在电池上方的上板，以及从罐和电池之间的上板侧向下延伸的侧板。 第一引导构件从侧板向罐延伸并向下倾斜。 优选地，设置在第一引导构件下方的第二引导构件的第一端被定位成比第一引导构件的远端更靠近电池，其中第二引导构件向下倾斜朝向水箱。
