Provided is a working machine with which filter regeneration can be performed by means of a manual operation if an accumulated amount of particulate matter (PM) is equal to or greater than a first accumulation amount threshold and less than a second accumulation amount threshold. This working machine is provided with: a manual switch; a filter which collects particulate matter contained in exhaust gas expelled from a motor; a first regeneration control unit which performs automatic regeneration by automatically burning the particulate matter if the accumulated amount of particulate matter collected by the filter is equal to or greater than the first accumulation amount threshold; a second regeneration control unit which performs manual regeneration by burning the particulate matter in response to a command from a manual switch if the accumulated amount is equal to or greater than the second accumulation amount threshold, greater than the first accumulation amount threshold; and a third regeneration control un
