A working machine provided with a main body and a working device attached to the main body, the working device including: a working arm having a distal end movable in vertical directions and front-rear directions; and a bucket rotatably attached to the distal end and defining a space for accommodating an object and an opening face letting the space open, the working machine comprising: a load detection part for detecting a load value of the object accommodated in the bucket; a posture detector for detecting a posture of the working device; an angle detection part for detecting a bucket angle that is an angle of the opening face of the bucket with respect to a vertical direction orthogonal to a horizontal plane on the basis of detection data indicating the posture of the working device detected by the posture detector; characterised in that the working machine further comprises an accommodation determination part for determining whether the object is accommodated in the bucket or not on the basis of the load value detected by the load detection part; and a discharge determination part for determining that the object accommodated in the bucket is discharged when the bucket angle detected by the angle detection part is on a discharge side beyond a predetermined discharge reference angle, and the load value detected by the load detection part is smaller than a load threshold, after the accommodation determination part determines that the object is accommodated in the bucket, wherein the discharge reference angle is an angle of the bucket in a posture allowing the accommodated object to be discharged. the working device including: a working arm having a distal end movable in vertical directions and front-rear directions; and a bucket rotatably attached to the distal end and defining a space for accommodating an object and an opening face letting the space open, a working arm having a distal end movable in vertical directions and front-rear directions; and a bucket rotatably attached to the distal end and defining a space for accommodating an object and an opening face letting the space open, the working machine comprising: a load detection part for detecting a load value of the object accommodated in the bucket; a posture detector for detecting a posture of the working device; an angle detection part for detecting a bucket angle that is an angle of the opening face of the bucket with respect to a vertical direction orthogonal to a horizontal plane on the basis of detection data indicating the posture of the working device detected by the posture detector; characterised in that the working machine further comprises an accommodation determination part for determining whether the object is accommodated in the bucket or not on the basis of the load value detected by the load detection part; and a discharge determination part for determining that the object accommodated in the bucket is discharged when the bucket angle detected by the angle detection part is on a discharge side beyond a predetermined discharge reference angle, and the load value detected by the load detection part is smaller than a load threshold, after the accommodation determination part determines that the object is accommodated in the bucket, wherein the discharge reference angle is an angle of the bucket in a posture allowing the accommodated object to be discharged. a load detection part for detecting a load value of the object accommodated in the bucket; a posture detector for detecting a posture of the working device; an angle detection part for detecting a bucket angle that is an angle of the opening face of the bucket with respect to a vertical direction orthogonal to a horizontal plane on the basis of detection data indicating the posture of the working device detected by the posture detector; characterised in that the working machine further comprises an accommodation determination part for determining whether the object is accommodated in the bucket or not on the basis of the load value detected by the load detection part; and a discharge determination part for determining that the object accommodated in the bucket is discharged when the bucket angle detected by the angle detection part is on a discharge side beyond a predetermined discharge reference angle, and the load value detected by the load detection part is smaller than a load threshold, after the accommodation determination part determines that the object is accommodated in the bucket, wherein the discharge reference angle is an angle of the bucket in a posture allowing the accommodated object to be discharged.
