<p>The hydraulic system (40) for a work vehicle (1) includes a main hydraulic pump (p1), a main supply circuit (M) through which pressurized oil from the main hydraulic pump flows, a sub hydraulic pump (p2), and a sub supply circuit (S) through which pressurized oil from the sub hydraulic pump flows. The main supply circuit supplies pressurized oil to a hydraulic travel motor (5L,5R) that drives a travel device (2) and a service actuator (27) that is disposed in an attachment with which the work vehicle is detachably furnished. The sub supply circuit merges with the main supply circuit and supplies pressurized oil to the service actuator. The hydraulic system for a work vehicle further includes a flow amount adjustment valve (v11) that adjusts the flow amount of the pressurized oil from the sub supply circuit that merges with the main supply circuit.</p> |
