A hydraulic circuit for a work vehicle comprising: a first actuator; a second actuator; a hydraulic pump that supplies hydraulic oil to the first actuator and the second actuator; a first direction switching valve that switches a direction of and adjusts a flow rate of the hydraulic oil supplied to the first actuator; a second direction switching valve that switches a direction of and adjusts a flow rate of the hydraulic oil supplied to the second actuator; a pilot pump that supplies pilot hydraulic oil to the first direction switching valve and the second direction switching valve; a first operation device capable of switching, according to an operation, a direction and a pressure of the pilot hydraulic oil supplied to the first direction switching valve; a second operation device capable of switching, according to an operation, a direction and a pressure of the pilot hydraulic oil supplied to the second direction switching valve; a pressure control unit that is provided in an oil passage between the second operation device and the pilot pump and controls a primary pressure of the pilot hydraulic oil supplied to the second operation device; and a control command transmitter that transmits a control command to the pressure control unit, wherein while the first operation device is operated, the control command transmitter transmits, to the pressure control unit, a first command to reduce the primary pressure from a reference pressure to a first command pressure and keep the primary pressure at the first command pressure, and when the second operation device is operated in a state where the first operation device is operated, the control command transmitter transmits, to the pressure control unit, a second command to gradually increase the primary pressure from the first command pressure to the second command pressure. a first actuator; a second actuator; a hydraulic pump that supplies hydraulic oil to the first actuator and the second actuator; a first direction switching valve that switches a direction of and adjusts a flow rate of the hydraulic oil supplied to the first actuator; a second direction switching valve that switches a direction of and adjusts a flow rate of the hydraulic oil supplied to the second actuator; a pilot pump that supplies pilot hydraulic oil to the first direction switching valve and the second direction switching valve; a first operation device capable of switching, according to an operation, a direction and a pressure of the pilot hydraulic oil supplied to the first direction switching valve; a second operation device capable of switching, according to an operation, a direction and a pressure of the pilot hydraulic oil supplied to the second direction switching valve; a pressure control unit that is provided in an oil passage between the second operation device and the pilot pump and controls a primary pressure of the pilot hydraulic oil supplied to the second operation device; and a control command transmitter that transmits a control command to the pressure control unit, wherein while the first operation device is operated, the control command transmitter transmits, to the pressure control unit, a first command to reduce the primary pressure from a reference pressure to a first command pressure and keep the primary pressure at the first command pressure, and when the second operation device is operated in a state where the first operation device is operated, the control command transmitter transmits, to the pressure control unit, a second command to gradually increase the primary pressure from the first command pressure to the second command pressure.
