PROBLEM TO BE SOLVED: To provide a crop harvester for solving problems in which a work height such as a drawing device of a conventional onion harvester can be changed by enabling a ground track roller provided at left and right one side of a machine body and turnable in the lateral direction to move up and down, however, when the ground track roller turns freely in the lateral direction due to the ground resistance with the field surface, the traveling direction of the machine body is swung in the lateral direction, and the operability of the machine body is lowered and the drawing position of the onion is disturbed.SOLUTION: A crop harvester is provided with: a handling member (91) for operating a machine body by a worker; left and right travelling drive wheels (84R, 84L) traveling on furrow ridges; a drawing device (20) for holding and drawing crops from the field; and a ground track roller (73) for changing a drawing work height of this drawing device (20). A traveling posture of the ground track roller (73) can be operated by the handling member (91). |
