Claim:
A grass catcher for a lawn mower, the grass catcher comprising: a frame; at least first and second venturi baffles supported by at least the frame of the grass catcher, the first and second venturi baffles each causing a venturi effect to be created in which air from outside the catcher is pulled or sucked into the catcher via a fresh air path in a vacuum manner during operation of the mower when grass from at least one blade of the mower is blown into the catcher via a grass-blown path, wherein the grass-blown path is different than the fresh air paths for the first and second venturi baffles; and wherein the first venturi baffle angles upwardly from a bottom of the grass catcher and causes grass coming into the catcher via the grass-blown path to move upwardly, and the second venturi baffle angles inwardly from a sidewall of the grass catcher and causes grass coming into the catcher to curve laterally so that the first and second venturi baffles cause incoming grass to move in different directions.
