Abstract: PROBLEM TO BE SOLVED: To prevent a grass dividing lever at an unreaped ground side from coming into contact with a levee in positioning a reaping part outside and reaping at the edge of the levee. SOLUTION: A reaping part 5 is connected to the front part of a self-propelled machine body 4 placed on a thresher 2. The reaping part 5 is integrally constituted changeably from the self-propelled machine body 4 in position in a set zone in the right and left direction. A grass dividing lever 10 at an unreaped ground side is constituted so as to freely operate the rocking position change from a grass dividing action position in which the grass dividing lever 10 at the unreaped ground side is extended laterally outward to a housed position in which the lever stands in line with the side of the self-propelled machine body 4. The grass dividing lever 10 at the unreaped ground side is constituted so as to be operated and rocked to the self-propelled machine body 4 side while passing the housed position in a changed state in position to the unreaped ground side. This grass divider is equipped with a stopper 16 changeable from an obstruction position for preventing the rocking of the grass dividing lever 10 at the unreaped ground side over the housed position to a releasing position for canceling the obstruction position.
