Work vehicle

A work vehicle having an engine and an exhaust gas purifying device for purifying exhaust gas of the engine in an engine compartment,

• wherein the exhaust gas purifying device is placed above the engine, and comprises a cylindrical oxidation catalyst device, a cylindrical reducing agent injection device, and a cylindrical selective catalytic reduction device,
• the oxidation catalyst device is placed with a central axis of the oxidation catalyst device oriented along a right and left direction of the work vehicle,
• the reducing agent injection device is placed with a central axis of the reducing agent injection device oriented along a front and rear direction of the work vehicle,
• the selective catalytic reduction device is placed with a central axis of the selective catalytic reduction device oriented along the front and rear direction of the work vehicle,
• the oxidation catalyst device, the reducing agent injection device, and the selective catalytic reduction device are arranged so as to have a relationship that the central axes thereof become the same in height, and
• the selective catalytic reduction device is placed with the central axis of the selective catalytic reduction device passing through the oxidation catalyst device.
