PROBLEM TO BE SOLVED: To solve such a problem that in the conventional combines, it is difficult for workers to confirm the abnormality in a threshing-screening work. SOLUTION: The combine is provided with a threshing part 4 to thresh culms reaped by a reaping part 6, a screening part 5 to separate the threshed culms to clean grains and tailings, and a grain tank 8 to store the clean grains. The combine is further provided with: a charged quantity detection sensor 61 to measure the quantity of threshed material charged to the screening part 5; a mass detection sensor 62 to measure the mass of the clean grain stored in the grain tank 8; a loudspeaker 67 generating an abnormality alarm; and a controlling part 60 to calculate the estimated mass of the clean grain in the grain tank 8 based on the quantity of the charged grain detected by the charged quantity detection sensor 61, judging the abnormality when the difference between the estimated mass of the clean grain and the mass detected by the mass detection sensor 62 is larger than a preset level, and generating an abnormality alarm from the loudspeaker 67.
