Abstract
Abstract A wheel supported attachment for a self-powered lawn mower is attached in trailing relation to the mower and a cylindrical brush, driven by power from the mower, sweeps grass cuttings and other debris upwardly into a hood in which a centrifugal blower operates to receive the material and blow it into an open-topped container removably mounted on the attachment.
