    Abstract: An improved leaf and debris collection apparatus is described which features a centrifugal fan mounted on a wagon and driven by an engine, the inlet side of the fan being connected to an inlet head just above ground level and its outlet side connected to an outlet plenum, comprising an outlet port for attachment of a disposable bag. A punch is provided for punching a large number of holes in the disposable bag so that air pressure is not collected within, so that the disposable bag can be used to collect the leaves and debris. In a preferred embodiment, the plenum has holes formed therein for release of air pressure, and the bag is disposed vertically beneath the plenum.
