<p>The machine has a main frame (18) with two hinged support frames (16). The implements carried on the frames are driven by shafts (25,27), and the frames can be swivelled between a transport and an operating position. - When the hinged support frames are swung to their working position, their shafts (25) are aligned with the shafts (27) of the fixed frame cross-member (23). The abutting ends of the shafts have coupling elements (50) in the form of short arms with coupling heads at the outer ends. These heads are so shaped that the flat surface of a head, attached to the arm of one shaft, abuts against the flat surface of a head on the arm of the opposing shaft.</p> |
