PURPOSE: To maintain a harvesting mechanism at a fixed position in transporting by blocking control in the state of being freely lockable to the supporting beam of a limiter to the supporting beam by a locking device at the time of transporting. CONSTITUTION: The limitter 41 provided for a chassis 3 is connected with a connecting structure 5 through a joint 64 with a geometric axis nearly parallel with the geometric axis 16A of a joint 16 at the time of operation and connected with the supporting beam 6 in the freely rockable state or in a state similar to it. The rocking tip part of the limiter is locked to the transporting position of pulling up the harvesting mechanism 4 by the locking device 43 blocking to the supporting beam at a position where the supporting beam is rotated upward by the maximum amount.
