Abstract
A working machine includes: an operation state detection unit configured to detect a physical amount output according to an operation of an operation lever; a time integration unit configured to calculate a time integration value by performing time integration of the physical amount; a determination unit configured to cause the time integration value and a predetermined operating angle of an excavating and loading mechanism associated with the operation of the operation lever to correspond to each other, and to determine that the operation of the operation lever has been performed, at a time the time integration value becomes a predetermined integration value or more; and a counting unit configured to count number of times of a series of excavating and loading work.
