Abstract: An apparatus for collection and reduction of yard debris combining a frontally facing vacuum pick up with a chipper-shredder-blower unit to induce airflow for entraining debris collected at the vacuum pick up; reduce the entrained debris to a more manageable volume; impel the reduced debris to a two-stage free-flow-separator device for removing the debris from the air in which it is entrained; and deposit the debris in a detachable accumulator for subsequent dumping.

Abstract: An apparatus for collection of yard debris combines a vacuum pick up with a blower unit, a separator, and a detachable accumulator with an attached roller to support the accumulator upon detachment from the separator. The apparatus collects and entrains debris in an airflow induced at the vacuum pickup, impels the debris to the separator which removes the debris from the airflow, and deposits it in the accumulator which is supported by a roller to aid subsequent dumping when the accumulator is detached.
