A mounting structure for attaching an elongated swather head to a tractor of the bi-directional type, the structure mounting the head in front of the tractor in a swathing direction of travel and accommodating swinging movement of the head to a trailing transport mode behind the tractor when travelling in a direction opposite to the swathing direction. The mounting structure is carried by the tractor which, in the operational mode of the swather, is disposed to one side of the center-line of the swather head. The mounting structure includes members for securement to the tractor and an elongated support member projecting transversely across the front of the tractor to the side of the tractor opposite to the center-line of the swather head. The head has a rear frame member which extends parallel to the head behind an intermediate portion thereof and is carried at one end by a hinge connection to the support member at the side of the tractor opposite to the center-line of the swather head. The hinge connection permits pivoting of the frame member of the swather head about a substantially vertical axis for accommodating the swinging movement of the swather head to a trailing transport mode. A lock is associated with the frame and support members for selectively holding the frame member against the swinging movement when used in the swathing operation.
