<p>Tractor-drawn agricultural mower has three crop-cutting rotors rotatable about vertical axes and carrying crop-feeding drums. Two of the rotors contra-rotate inwards to feed cut crop between them. The third rotor is offset rearwards from a straight line intersecting the axes of rotation of the other two rotors and rotates in the same direction as the rotor adjacent it so that the crop which it cuts passes behind the adjacent rotor and towards the crop which has passed between the other two rotors, whereby a single swath of crop is produced by the mower.</p> |
