Abstract
A hydraulic system of a work machine with a hydraulically controlled implement includes: an operating oil flow passage for flowing operating oil from a main pump; a boost flow oil passage for supplying operating oil to the operating oil flow passage; a connection unit for connecting the implement which is provided downstream of the confluence on the operating oil flow passage; a controller for controlling the high-flow valve; and a high-flow switch which is connected to the controller and is configured to effect or cancel a command of the amount increase on a high-flow valve. Annunciation is made when the connection unit is connected to a high-flow actuator for the implement requiring an amount increase of the operating oil, and the amount increase is effected by the high-flow valve in accordance with an operation of the high-flow switch.
