Abstract
The invention provides a cutting head assembly for a lawnmower, trimmer, or similar device which includes a plurality of lower cutting elements mounted to a disc-shaped support member. A plurality of upper cutting elements are also mounted to the disc-shaped support member at a higher elevation, such that each upper cutting element is directly above a corresponding lower cutting element. This allows for a double cut mulching effect in use. An air foil can be provided with the upper cutting elements to create an upward vacuum which positions the grass for a clean cut by both the upper and lower cutting elements. The cutting elements can comprise cutting blades and/or flexible cutting filaments.
