<P>PROBLEM TO BE SOLVED: To provide a combine harvester designed to make hard to accumulate water in a crawler-traveled trace after its crawler traveled to prevent the soil from getting weak to improve the combine harvester's travelability in the farm. Ž<P>SOLUTION: The combine harvester 1 including a pair of left and right crawler traveling gears 17 is provided with a furrow opener 24 for forming furrows for draining use on the crawler-traveled traces is provided behind the respective crawler traveling gears 17. Thereby, furrows for draining use can surely be formed, resulting in making hard to accumulate water in the crawler-traveled traces. The furrow opener 24 is provided liftably relative to the machine body and disposed forward from the rear end of the machine body. Thereby, when a furrowing is not needed (when making no working travel, when the machine body is going back, or the like), the furrow opener 24 can be housed at a raised position, while, as the furrow opener 24 is forward from the rear end of the machine body, there is also no disadvantage of increasing the whole length of the machine body.
