PROBLEM TO BE SOLVED: To provide a work machine capable of accurately detecting plural kinds of abnormal states in which, shock generation directions are different respectively.SOLUTION: A work machine comprises a work element (for example, a rotary cutter) on a tip end side of a main pipe 2, and a rear end housing 21 on a rear end side. An acceleration sensor 44 is disposed in the rear end housing 21. The acceleration sensor 44 can detect a variation state of a position to a first direction (for example, an X-axis direction) and a variation state of a position to a second direction (for example, a Y-axis direction) at least. Based on the variation states in the respective direction detected by the acceleration sensor 44, a determination part performs predetermined determination processing related to a use state of the work machine.SELECTED DRAWING: Figure 5 |
