Abstract
A hydraulically powered working vehicle includes a turning section provided at an upper side of a travel unit capable of turning, and hydraulic circuits for the working vehicle. The hydraulic circuit for the working vehicle has a first actuator group including a one side traveling motor, a first variable capacity pump for driving the first actuator group, a second actuator group including an other side traveling motor and a turning motor, and a second variable capacity pump for driving the second actuator group. The second variable capacity pump is set so that a maximum value for discharge capacity per unit time becomes large compared to that of the first variable capacity pump.
