A machine for cutting vegetation comprises a vegetation cutter for cutting vegetation, a sensor element (8a) for detecting the boundary (13) between a region of cut vegetation (9) and a region of uncut vegetation (10), mounting means for mounting the sensor element such that, in use, the sensor element scans across an area of vegetation and produces a sensor signal which varies as the sensor element scans across the area of vegetation, and means for analysing the sensor signal to determine the position of said boundary. |
