PROBLEM TO BE SOLVED: To provide a working machine preventing damage to a filter due to excessive accumulation of PM even under a situation that requires moving the machine to a place of regeneration upon compulsory regeneration of the filter.SOLUTION: The working machine includes an exhaust treatment device 4 having the filter 6 to trap the PM, a regeneration control section 31 for forcibly regenerating the filter, and a regeneration instruction device 23 for instructing the regeneration control section 31 to start the forcible regeneration. Further, the working machine includes an actual accumulation amount estimating section 35 for estimating an actual accumulation amount A, a reference accumulation amount storage section 36 for storing a reference accumulation amount B, a movement-associated accumulation amount estimating section 37 for estimating a movement-associated accumulation amount C accumulating upon moving the working machine to the place of regeneration, an accumulation amount determination section 39 for determining whether or not the actual accumulation amount A has reached an accumulation alarm amount D which is a value obtained by subtracting the movement-associated accumulation amount C from the reference accumulation amount B, and an alarm device 12 for notifying the arrival of a moving timing of the working machine to the place of regeneration when the actual accumulation amount A is determined to have reached the accumulation alarm amount D. |
