<p>The mower is suspended by arms (11) at an adjustable height from an agricultural implement (10). A lifting mechanism (12) is controlled by a feeler (15) on the mower (1), movable up and down and bearing against the ground (13). This is connected to a movement detector, which supplies control signals to the lifting mechanism. The feeler is mounted partly underneath the mower, bearing against the ground close to the mower working position.</p> |
