Abstract: An improved apparatus for cutting vegetation which is especially adapted to be employed with units having a top mounted gasoline motor interconnected by a drive tube to a lower rotating cutting head. An accessory handle is carried adjacent the motor. A housing carried on the lowermost drive tube encloses bearings and provides a journal for the cutting head. An actuator housing bolts to the housing and interfits for rigid support. A mechanical line feeder on the cutting head is operated by an actuating lever carried on the accessory handle through an interconnecting control cable. Reciprocation of the control lever operates the mechanical line feeder so that a predetermined length of cutting line is extended from the cutting head during rotation without interrupting cutting.
