PROBLEM TO BE SOLVED: To increase the capacity of a grain tank while preventing the interference of the grain tank with a transmission system for unloading grains in swinging displacement of the grain tank. SOLUTION: A grain tank 5 furnished with a grain unloading device 6 is placed in a swingably displaceable state around a rear vertical shaft P1 between a working position and a maintenance position. The input part 21 of the grain unloading device 6 is placed at the front part of the grain tank 5, a grain-unloading transmission system 22 to transmit the power of an engine 8 to the input part 21 is extended from the output shaft 9 of the engine 8 to the input part 21, the grain-discharging transmission system 22 and the input part 21 are made to be switchable between a transmitting state to connect these components in a transmittable state and a non-transmitting state to release the connection, and the grain-unloading transmission system 22 is made to be shiftable between a forwarded position entering into a swinging area A of the grain tank 5 to enable the connection with the input part 21 and a retreating position departing from the swinging area A of the grain tank 5 to allow the swinging displacement of the grain tank 5.
