ABSTRACT:
An improved lawn mower grass clipping catcher using vortical separation of grass clippings from exhaust air. The catcher includes a vortex exhaust baffle which deflects and diverts upward flow of air and clippings down and outwardly into the vortical flow, decreasing the escape of suspended clippings and dust from the catcher. The clippings fall into a plastic trash barrel which may contain a plastic trash bag. The barrel supports the housing in which the vortical air flow is initiated. The delivery chute is rectangular in cross section and scrolls around the housing to provide smoother air flow at the inlet of the housing by optimizing the tangentiality of entry of the inlet air. The delivery chute is rigid and provides cantilevered support for the housing when the housing is lifted about a hinge and located in a retracted position while the plastic barrel is being emptied.
