ABSTRACT OF THE DISCLOSURE In a mowing machine of the kind comprising a frame adapted to be mounted on a tractor three-point linkage, and a plurality of cutting units connected to the frame, including at least two laterally spaced side cutting units and a centre cutting unit positioned so as, in use, to cut the swath between the two swaths cut by the side cutting units, the side cutting units are mounted directly on the frame, so that in use part of the weight of the frame is supported by the side cutting units, and the centre cutting unit is mounted at the rear end of a mounting arm connected to the frame by a universal joint, biassing springs being connected between the frame and the mounting arm to increase the pressure exerted on the ground by the centre cutting unit so that it takes some of the weight of the frame from the side units and ensures uniformity of cut. The universal joint between mounting arm and frame also allows the centre unit to take the optimum line when the machine follows a curved path.
