Abstract: A work machine includes: an operation state detection unit detecting a physical amount output; a time integration unit calculating a time integration value; a determination unit determining that the operation of the operation lever is performed at a time the time integration value is not smaller than a predetermined integration value; a counting unit counting number of a series of the operations of the excavation-loading mechanism performed in a predetermined order as one series of the excavation-loading work; and a specific state detection unit detecting a specific operation state not related to the series of operations of the excavation-loading mechanism in a state in which an operation of the excavation-loading mechanism related to the series of excavation-loading work can be performed, and at a time the specific operation state is detected, the counting unit resets or corrects counting processing of the number of times of the series of excavation-loading work.
