<p>A lawn mower comprises a cutting unit consisting of two rotors (17) coupled together within a single casing (14) to rotate in opposite directions, they carrying at least two aligned blades (18), the distance between the axes of the rotors (17) being such that the areas covered by the blades (18) when rotating are partially superposed in correspondence with that axis of symmetry of the pair of rotors which coincides with the mower axis, the direction of rotation of the two rotors (17) being such that the direction of movement of the blades (18) when in proximity to said axis of symmetry is the same as the forward travel direction of the mower. <IMAGE></p> |
