A vegetation cutting device comprising a housing rotatably coupled to a shaft; a cutting head comprising a rotary cutting means for cutting vegetation, the cutting head being coupled to the shaft and being arranged to move between an edging mode in which the rotary cutting means rotates in a substantially vertical plane and a trimming mode in which the rotary cutting means rotates in a substantially horizontal plane; a motor mounted in the housing, the motor being arranged to drive the rotary cutting means; and a switching means mechanically coupled between the housing and the shaft and arranged to be actuated when the shaft rotates relative to the housing thereby changing the speed of the rotary cutting means when the cutting head moves between the edging mode and trimming mode. |
