ABSTRACT:
A convenience improvement in rotary mowers, trimmers and edgers of vegetation that have a rotating body from which one or more flexible cord-like filamentous cutting blades or flails extend radially so that additional flail length can be fed from the device by merely bumping the rotating body on the ground. The improvement includes a plurality of spline lugs on one portion which extend into a serpentinous cam slot on another. Bumping of the device on the ground causes the lugs to move from stable positions to other stable positions allowing relative movement between the outer case of the mower and a spool of flail therein so that predetermined length of flail is fed out through the case.
