A manipulator mechanism includes a rotary shaft rotatable about an axis extending in a first horizontal direction, an operation member disposed at one of opposite ends of the rotary shaft in an axial direction thereof to rotate together with the rotary shaft, an angle sensor disposed at the other of the opposite ends of the rotary shaft in the axial direction to detect a rotation angle of the rotary shaft, and a neutral return mechanism provided between the operation member and the angle sensor to return the operation member to a neutral position from a post-operation position which is a position to which the operation member has been moved.

Manipulator mechanism and working machine

A hydraulic system for a work machine includes a first switch valve and a first return circuit. The first switch valve is switchable between a confluent position and an isolation position. The first switch valve is switched to the confluent position such that a first operation fluid tube is connected to a second operation fluid tube and a first transmission fluid tube is connected to a second transmission fluid tube. The first switch valve is switched to the isolation position such that the first operation fluid tube is disconnected from the second operation fluid tube and the first operation fluid tube is disconnected from the second operation fluid tube.
