Mowing apparatus
 A mowing apparatus of the type having a rotatable disk-like casing containing one or more rolls of flatly and concentrically coiled string made of a high polymer synthetic material. Each coil of the string is interconnected at at least one point to the adjacent coil by the help of a fixing element so that it can be laterally payed out without the disjoining of the coil. The free end extends through the respective guide ports, outwardly from the casing in order to form a cutting flail with an effective working length.
