Abstract

A mulching unit for a mulching apparatus includes at least one cutting assembly or hammer having a rotatable support element and two cutting elements spaced apart from one another by a predetermined gap that allows debris to pass between the cutting elements, thereby increasing efficiency and enabling higher rotating speeds for sustained amounts of time. The cutting elements include tips that may be formed in one piece with the support element, e.g., a collar, and the tips may be covered with a protective layer of tungsten and/or carbide. Alternatively, the tips themselves can be made from tungsten and/or carbide and physically attached, e.g., by welding, to the collar to form an integral unit. The cutting elements may be mounted on support element halves that can independently rotate on a support rod of the mulching unit.
