Abstract
A working machines includes an identifying unit. A force sensor detachably supports a working head in the identifying unit. A controller circuit is designed to identify the working head based on the load detected at the force sensor. When the working head is replaced with another one, the load changes in the force sensor in the identifying unit. In general, the individual working head has the specific weight. The working heads can thus be differentiated from each other based on the weight. Accordingly, the controller circuit is allowed to reliably identify the working head after the replacement with a higher accuracy based on the detected load.
