An agricultural harvesting machine is provided having a frame, a crop processing unit that is movable with respect to the frame between an operating position, in which it is inserted into a channel through which crop can flow, and a non-operating position outside the channel. A transport unit is provided with a first arm articulated to the frame of the harvesting machine pivotably about a first vertical axis, a winch and a traction device connected to the winch for lifting the crop processing unit out of its non-operating position and for moving the crop processing unit into a position outside the harvesting machine. The transport unit further is provided with a second arm holding the traction device and articulated to the outer end of the first arm pivotably about a second vertical axis.
