PROBLEM TO BE SOLVED: To provide a combine harvester which is equipped with a multi-row reaping pre-treating portion and can smoothly convey grain straws, even when the quantity of joined grain straws is large. SOLUTION: This combine harvester which comprises a travel machine frame 2 having a threshing portion 7, a pre-treating portion 3 connected to the front portion of the travel machine frame 2, a right plant foot conveyer 38A for conveying the foots of grain straws reaped with the right reaping portions C1, C2 of the pre-treating portion 3 to the threshing portion 7, and a left plant foot conveyer 38D for conveying grain straws reaped with the left reaping portions C7, C8 of the pre-treating portion 3 to the convey downstream side of the right plant foot conveyer 38A to join the grain straws to the grain straws, is characterized by dividing the right plant foot conveyer 38A into an upstream conveyer 44 on the upstream side and a downstream conveyer 46 on the downstream side for forming a joining portion P to the left plant foot conveyer 38D, and driving the downstream conveyer 46 at a larger speed than the upstream conveyer 44.
