An improved mowing apparatus of the type having a rotatable reel-like casing about which a cutting string made of a high polymer synthetic material is directly wound. The coiled string is protected by a cap which is detachably mounted on the casing and locked for rotation therewith. The free end of the coiled string extends outwardly from the cap through one of guide ports provided in the peripheral wall of the cap, in order to form a cutting flail with an effective working length. The cap is elastically arranged to disengage from locking engagement with the casing for rotation relative thereto, so that the string may easily be payed out as the working flail becomes shortened through wear. |
