A work machine comprising: a work implement with a bucket; an actuator (16, 17, 18) for actuating the work implement; a controller for determining an operation of the work implement on a basis of at least one of posture information of the work implement and load information of the actuator (16, 17, 18), calculating a carried load representing a load value of carried stuff carried by the work implement in case it is determined that the bucket of the work implement has performed a carrying operation by turning and moving the bucket to a position above a cargo bed of a transportation machine, and integrating the carried load to calculate loadage (Mt) of the transportation machine; and a display device for displaying the loadage (Mt), characterized in that the controller calculates a remaining loadage (Mrem) that is obtained by subtracting the loadage (Mt) from a maximum loadage of the transportation machine, and a remaining loading cycle count (Nrem) that is obtained by dividing the remaining loadage (Mrem) by a bucket volume (Mbk) calculates a target carried load (Mtar) representing a target value for the carried load per bucket to be carried in a next carrying operation in case the loadage (Mt) is changed, on a basis of a quotient produced by dividing the remaining loadage (Mrem) by the remaining loading cycle count (Nrem), calculates a first set value, in case a magnitude of the target carried load (Mtar) is equal to or larger than a predetermined threshold value, and calculates a second set value smaller than the first set value, in case the magnitude of the target carried load (Mtar) is smaller than the predetermined threshold value, as a minimum integration load value for determining that the work implement has performed a loading operation depending on the magnitude of the target carried load, and calculates the loadage (Mt) by integrating the carried load in case it is determined that the work implement has performed a loading operation on the transportation machine on a basis of a posture of the work implement and in case the carried load is equal to or larger than the minimum integration load value. a work implement with a bucket;
