PROBLEM TO BE SOLVED: To surely and readily carry out vertically stretchable movement of an upper tank to a lower tank by a simple constitution and handle operation from an operation position in a stretchable grain tank. SOLUTION: The subject combine harvester is constituted of the upper tank and the lower tank and an upper grain-lifting cylinder and a lower grain-lifting cylinder by respectively vertically dividing the grain tank for housing grains and a first grain-lifting cylinder for feeding grains into the grain tank into two parts, and the upper tank and the upper grain-lifting cylinder are liftably installed so as to vertically carry out stretching movement to the lower tank and the lower grain-lifting cylinder, and the upper tank and the upper grain-lifting cylinder are interlocked so as to carry out integral lifting and lowering movement through a lifting and lowering drive means composed of a handle provided near a drive part, a rack installed on the side of the upper tank or the upper grain-lifting cylinder and a pinion engaging with the rack and rotating by rotation operation of the handle.
