Abstract: A controller of a wheeled hydraulic excavator executes control of a vibration suppression function to control the flow of a hydraulic fluid from a hydraulic cylinder that drives a work implement, thereby suppressing vibration of the hydraulic cylinder when the rotation speed of wheels reaches a predetermined speed or higher. Furthermore, the controller disables the control of the vibration suppression function when the vehicle body is jacked up by the work implement, even when a vibration suppression instructing device has given an instruction for enabling the control of the vibration suppression function.
