The multi-purpose attachments for power lawn mower blades are designed to increase the efficiency and usefulness of the mower both to cut lawns and blow snow, leaves or debris from areas. The serrated cutter attachments allow replacement with ease, have longer lasting sharpness and the cutting surface is protected from foreign objects. In addition, the serrated cutters may be manufactured economically enough to allow used cutter attachments to be discarded. The blower attachments are designed to create adequate air pressure to remove snow, leaves and debris from select areas. The blower attachments are also designed to be resilient to assure safe use if foreign objects are struck during such use.
