A work vehicle comprising: an engine; a hydraulic pump configured to discharge hydraulic fluid due to being driven by the engine and be able to change the discharge direction of the hydraulic fluid; a hydraulic motor configured to be driven by the hydraulic fluid which is discharged from the hydraulic pump and where a driving direction is changed between a forward progression direction and a backward progression direction according to the discharge direction of the hydraulic fluid from the hydraulic pump; a pump displacement control cylinder configured to control the displacement of the hydraulic pump according to pressure of the hydraulic fluid which is supplied to the pump displacement control cylinder and switch the discharge direction of the hydraulic fluid from the hydraulic pump according to the supply direction of the hydraulic fluid which is supplied to the pump displacement control cylinder; a forward and backward progression switching valve configured to switch the supply direction of the hydraulic fluid to the pump displacement control cylinder; and a forward and backward progression operation member configured to be operate in order to switch forward and backward progression of the vehicle; characterized by a pressure control valve configured to control the pressure of the hydraulic fluid which is supplied to the pump displacement control cylinder according to a command value which is input the pressure control valve; and a control section configured to execute pump shuttle control which reduces the command value to the pressure control valve when switching between forward and backward progression using the forward and backward progression operation member. an engine; a hydraulic pump configured to discharge hydraulic fluid due to being driven by the engine and be able to change the discharge direction of the hydraulic fluid; a hydraulic motor configured to be driven by the hydraulic fluid which is discharged from the hydraulic pump and where a driving direction is changed between a forward progression direction and a backward progression direction according to the discharge direction of the hydraulic fluid from the hydraulic pump; a pump displacement control cylinder configured to control the displacement of the hydraulic pump according to pressure of the hydraulic fluid which is supplied to the pump displacement control cylinder and switch the discharge direction of the hydraulic fluid from the hydraulic pump according to the supply direction of the hydraulic fluid which is supplied to the pump displacement control cylinder; a forward and backward progression switching valve configured to switch the supply direction of the hydraulic fluid to the pump displacement control cylinder; and a forward and backward progression operation member configured to be operate in order to switch forward and backward progression of the vehicle; a pressure control valve configured to control the pressure of the hydraulic fluid which is supplied to the pump displacement control cylinder according to a command value which is input the pressure control valve; and a control section configured to execute pump shuttle control which reduces the command value to the pressure control valve when switching between forward and backward progression using the forward and backward progression operation member.
