Abstract: A work vehicle includes a vehicle body, a guiding pipe, a first heating section, and a second heating section. The vehicle body has a partition wall that partitions a space in an inner section into a first region and a second region. The guiding pipe is configured to guide a reducing agent. The guiding pipe has a first pipe section and a second pipe section. The first pipe section is positioned inside the first region. The second pipe section is positioned in the second region. The first heating section heats the first pipe section. The second heating section heats the second pipe section and adjusts the temperature independently from the first heating section.

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 valve for switching between a merging position for causing a first oil passage for driving a bucket and a second oil passage for driving an arm to communicate with each other, and a diverging position for separating the first oil passage and the second oil passage. The work vehicle is adapted to switch the valve from the merging position to the diverging position, when one of a pump pressure in the first pump and a pump pressure in the second pump comes to be equal to a predetermined value during an excavation operation. The work vehicle is adapted to control both pumps, such that the amount of the oil discharged from the first pump is larger than the amount of the oil discharged from the second pump, when the pump pressure in the first pump is equal to or more than the predetermined value.
