<P>PROBLEM TO BE SOLVED: To solve such a problem that foliage portions for two ridges are discharged between the ridges on every other ridge, accumulated and stepped with a travel vehicle to obstruct the travel of the travel vehicle and the harvesting works of the harvester. Ž<P>SOLUTION: In the subterranean stem crop harvester having a pull-out conveyer 3, a cutting portion 4 for cutting off the bulb portions of subterranean stem crops from the foliage portions, a conveyer 6 for discharging the foliage portions, a bulb-receiving portion 5, and a foliage portion-discharging chute 7 disposed below the final end portion of the conveyer 6 for discharging the foliage portions, the foliage portion-discharging chute 7 is disposed in the lateral direction orthogonal to the travel longitudinal direction with the opened surface side of the foliage portion-discharging chute 7 facing upward, can be turned around the approximately middle portion thereof in the longitudinal direction as a turning support 70b so that the right or left ends of the foliage portion-discharging chute 7 are moved in the upward or downward, and is disposed in a left inclined or right inclined state on the rear side view. In addition the foliage portion-discharging chute 7 are vibrated. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
