PROBLEM TO BE SOLVED: To solve a problem that there is a case in which the volume of a grain tank can sufficiently not be utilized, because whether the grain tank is filled with the harvested grains in the grain tank or not is judged with a full volume sensor attached to a place of the grain tank and further because the filling rate (the rate of the bulk volume occupied with the harvested grains, when the volume of the space in the grain tank is 100%) is largely different by the kind of the harvested grains. SOLUTION: Grain sensors 121, 122, 123, 124, 125, and 126 as harvested grain-detecting sensors are disposed at different places for respective kinds of the harvested grains to detect the harvested grains, when the filling rates of the harvested grains in the grain tank 30 are enhanced.
