Apparatus for cutting vegetation and the like, comprising:
- a housing rotatable in a cutting plane about an axis of rotation and having at least one flexible non-metallic line with a free end extending outward of the periphery of said housing and with an unobstructed peripheral travel in said cutting plane,
- driving means for revolving said housing about an axis and to extend said free end of said line radially from said housing into said cutting plane,
- tubular handle means connected between said housing and said driving means to manipulate said apparatus,
- a cutting blade assembly for manually and selectively cutting said line adjacent said free end,
- mounting means for securing said cutting blade assembly on said tubular handle means in spaced relationship from said cutting plane, and
- said mounting means providing for movement of said cutting blade assembly to a selected location along said tubular handle means whereby said line in taut configuration is severed by said cutting blade assembly to a predetermined working length of said free end of said line which extends radially into said cutting plane for effective and efficient vegetation cutting.
