A hydraulic soft-start system includes a first flow valve in fluid communication with a pressure source and an inlet of a motor. A first restricting orifice is disposed between the first valve and the inlet. A second flow valve is in fluid communication with the first valve and the inlet. A pilot for actuating the second valve is in fluid communication with the inlet. A second restricting orifice is disposed between the pilot and the inlet. Upon actuation of the first valve, a first flow is passed from the pressure source via the first orifice to the inlet, placing the motor in a partially-actuated state. The second valve being actuated after a threshold pressure of the pilot is reached allowing a second flow to pass from the pressure source to the inlet. The second flow being higher than the first flow, thereby placing the motor in a fully-actuated state.
