Abstract:
Provided is a hydraulic system that can suppress costs and achieve comfortable operability. A hydraulic system (10) that comprises: a first hydraulic pump (11) and a second hydraulic pump (12); a first travel motor (21) and a second travel motor (22); a first actuator (31) that drives a dozer; and a circuit switching unit (40). The circuit switching unit (40) switches a hydraulic circuit (13) between a first circuit state and a second circuit state. In the first circuit state, hydraulic fluid is supplied from the first hydraulic pump (11) to the first travel motor (21) and the first actuator (31) and from the second hydraulic pump (12) to the second travel motor (22) and the first actuator (31). In the second circuit state, hydraulic fluid is supplied from the first hydraulic pump (11) to the first travel motor (21) and from the second hydraulic pump (12) to the second travel motor (22) but is not supplied from the first hydraulic pump (11) and the second hydraulic pump (12) to the first actuator (31).
