Abstract: A working machine according to one aspect of the present disclosure comprises an operation rod, a leading end unit, a rear end unit, and a drive permitter. The operation rod is configured to be transformable between an extended state and a non-extended state. The leading end unit is provided at one end of the operation rod. The leading end unit comprises a motor configured to drive a working element. The rear end unit is provided at the other end of the operation rod. The rear end unit comprises a controller configured to control driving of the motor. The drive permitter is configured to permit driving of the motor when the operation rod is in the extended state and not to permit driving of the motor when the operation rod is in the non-extended state.
