Stage: PROBLEM TO BE SOLVED: To improve the convenience of an operation system for changing an operation speed of an actuator of a work machine.SOLUTION: An operation system comprises a change gear for maintaining a speed stage of an actuator to a first speed stage when an operation current is not inputted, and switching the speed stage to a speed stage corresponding to the operation current when the operation current is inputted, a control device for inputting the operation current corresponding to an operation of a first operation member to the change gear when a work mode is other than a prescribed work mode, a second operation member, and a relay harness connected between a power supply and the change gear, and inputting the operation current from the power supply to the change gear not via the control device. The relay harness has a first switching part for carrying the operation current when the second operation member is operated, and blocking the operation current when the second operation member is not operated, and a second switching part for permitting the supply of the operation current to the change gear from the first switching part when the work mode is other than the prescribed mode, and blocking the supply of the operation current to the change gear from the first switching part when the work mode is the prescribed mode.SELECTED DRAWING: Figure 5 (Grant)
