ABSTRACT:
A working machine control device is provided which can surely determine whether working equipment attached to a working machine is in an operation state. The working machine control device is configured to control a vibration generating device that is supplied with pressure oil from a hydraulic pump to generate vibration to operate working equipment attached to a working machine. The working machine control device includes a controller that is configured to obtain frequency characteristic of the pump pressure based on a pump pressure value that is detected by a pressure sensing section, and to determine whether said working equipment is in an operation state or not based on said frequency characteristic.
