Abstract: A balanced mower head for carrying a plurality of monofilament lines. The mower head is suitable for being mounted on the shaft of conventional rotary mower and includes certain features which particularly adapt the head for universal fit and for replacing the conventional mower blade with monofilament cutting lines thereby substantially enhancing the safety of the cutting operation. The head defines a bore extending therethrough which is proportioned for receiving the shaft which normally carries the blade of a conventional rotary mower. A plurality of line holders extend outwardly from the head body and define at their outboard end portions an opening which is proportioned for receiving a line such that the line extends outwardly from the outboard end portion of each of the line holders to perform the cutting operation upon rapid rotation of the head. Means are provided for generating air currents in a vertical direction during the cutting operation to stand the vegetation up prior to its being cut.
