PROBLEM TO BE SOLVED: To provide a combine harvester having pulling-up tines capable of excellently securing harvesting efficiency. SOLUTION: The combine includes a grain culm pulling-up device and an auxiliary pulling-up device configured to pull up non-reaping grain culms by upward movement along the lower half-arcuate part and the linear part of a tine chain in a state wherein many pulling-up tines are fitted to the tine chain wound around and extended across a pair of upper and lower sprockets and protruded from the tine chain in a substantially orthogonal state, wherein the lower part of the grain culm pulling-up device and the upper part of the auxiliary pulling-up device are partially arranged overlapping with each other in the front-rear direction, and the moving speed (peripheral speed) of pulling-up tines of the lower semi-arcuate part at the auxiliary pulling-up device is substantially equal to the moving speed of pulling and raising tines of the linear part at the grain culm pulling-up device.
