Combine harvester

Provided is a combine harvester capable of shortening discharge operation time by moving a transverse discharge portion of a discharge auger above a sun shade of a manipulation portion. According to the combine harvester, a threshing device for threshing and screening grain stalks is arranged on the left side of the rear portion of a pre-harvesting treatment device for harvesting the grain stalks, and an operating part for an operator to ride is arranged on the right side of the rear portion of the pre-harvesting treatment device. A grain tank for storing threshed and screened grains and a discharge auger for discharging the grains stored in the grain tank to the outside are arranged on the rear side of the operating part; the discharge auger is formed by a longitudinal discharge part which extends in the vertical direction on the rear side of the grain tank and rotates around the axis, a transverse discharge part which extends to the front left side from the upper part of the longitudinal discharge part and
