A work vehicle includes an engine, a variable displacement hydraulic pump, a hydraulic motor, an exhaust treatment device, and a controller. The engine drives the variable displacement hydraulic pump. The variable displacement hydraulic pump is configured to change the discharge direction of the hydraulic fluid. Depending on the discharge direction of the hydraulic oil from the variable displacement hydraulic pump, the hydraulic motor is configured to change the driving direction to the forward direction or the reverse direction. The exhaust treatment device is configured to treat the exhaust from the engine. The controller is configured to increase the speed of the engine to a predetermined first speed or greater and to change the discharge direction of the variable displacement hydraulic pump to a neutral state during regeneration of the exhaust treatment device.
