Abstract
A controllermounted on a work machine calculates a target carried load representing a target value for a carried load carried by the work machine on the basis of loadage of a transportation machine in case the loadage is changed, calculates a minimum integration load value depending on the magnitude of the calculated target carried load, and calculates the loadage by integrating the carried load in case it is determined that a work implement has performed a loading operation on the transportation machine and in case the calculated carried load is equal to or larger than the minimum integration load value.
