ABSTRACT:
A rotary cutter head mounted on the end of a handle to power rotate at high speed one or more centrifugally whirled free ends of a reserve of nylon line wound on a spool co-axially pivotally mounted within the head.
A co-axially spring biased indexer is subject to inertia applied through the handle while the device is running to effect the feeding of precise increments of line from the spool to the free line ends. The indexer is automatically self-inhibiting when the line ends reach a predetermined optimum length of approximately eight inches and continues to be self-inhibiting until the line ends wear down, in use, to less than a predetermined minimum length of approximately five inches.
