A blower attachment for a lawnmower. The blower attachment includes an impeller and a shroud that are attachable to the lawnmower deck or undercarriage. The shroud includes a disc-shaped bottom portion defining a reduced-diameter opening. The impeller is centrally positioned over the reduced-diameter opening. Rotation of the impeller draws air through the reduced-diameter opening before being discharged from the lawnmower for the removal of debris from a lawn surface.
