Abstract
An apparatus for collection and reduction of twig-containing yard debris combining a frontally facing twig breaker 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 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.
